Dirty Sock Syndrome Part 1

Upon entering your home, the first thing you noticed is the stinky odor. It is not the garbage, neither the piled-up laundry of your little munchkins. What could be the culprit then?

Your air conditioning.

Your house might be suffering from dirty sock syndrome.

The average American spends almost 93 percent of their life indoors, which makes indoor air quality an immediate issue. Dirty sock syndrome attacks most homes, and you need to pay strict attention to it.

In this two-part article series, we will discuss what dirty sock syndrome actually is, what causes it, and how to solve it efficiently.

You can jump to part two here.

What Is Dirty Sock Syndrome?

Dirty sock syndrome is a stale, foul-smelling odor that is often produced from an air conditioner with a dirty coil. This coil is the heat pump coil in the blower or air handler of your AC. Apart from a very dirty coil, there are also little microbial organisms present that feed on the dust, dirt, and other things that’s accumulated on it. This is why your home is dealing with a terrible smell.
The smell travels as your AC pushes air around the home, making all rooms have a disgusting odor. Some homeowners mistake dirty sock syndrome as a mold problem because of its mold-like smell. This can cause for a serious concern since mold leads to headaches and other health issues.

What Causes Dirty Sock Syndrome?

Bacteria and fungus growing on the evaporator coil.
Constant use of your air conditioning can cause moisture formation on the evaporator coils. Dust will then be collected inside the system and fasten itself to the coils.
Once attached, the dust and moisture can grow bacteria. The cold and hot temperatures used by the air conditioning makes it an excellent place for the bacteria to flourish.
The bacteria and fungus growth will lead your AC system to slow rot from within. It is because of the decomposition that you smell a stinky odor when the unit is on.

Is Dirty Sock Syndrome Dangerous?

No doubt, dirty sock syndrome smells horrible and is a real annoyance. But fortunately, it is not usually considered devastating or life-threatening since the mildew and bacteria are not extremely hazardous to the health but could irritate asthma or other respiratory conditions.
Though at some point, dirty sock syndrome can pose health risks if mold occurs in the air conditioning unit and starts to develop. It can cause sneezing and coughing and those with severe allergies, asthma, or have respiratory problems will likely the suffer most.
You may also experience eye irritation and difficulty breathing if mold grows within your system. The strong smell from the AC unit can make you feel sick too. Long exposure to mold also carries long-term health risks as it emits microbial volatile organic compounds – gasses which generate the odor that associated with mold.

If you have Dirty Sock Syndrome or mold has grown inside your AC, you need have a professional  conduct an immediate, thorough inspection and cleaning of the HVAC system.

How-to Tips For AC Use In Florida Winter

Winter is just around the corner! You are almost ready – how about your air conditioning unit? Check out our important tips you can take so as to ensure the best performance of your unit in the next summer season!

How to prepare your AC for Winter

  1. Check And Replace The Air Filter

    When was the last time you look over the filter of your AC unit? Cleaning the filter is specifically crucial if you run the unit often. The filter’s purpose is to ensure healthy air and good airflow as well as prevent and protect air conditioning from breaking down. This will also save your energy costs. Replace the air filter at least every two months, preferably every month. We recommend changing your filter every time you get your power bill. It is an easy reminder that it has been a month.

  2. Change The Thermostat Settings

    In order to enjoy electricity savings and home comfort during winter months, consider programmable thermostats. A programmable thermostat allows you to set humidity and temperature according to the weather condition and to your schedule.

  3. Give The AC System A Thorough Cleaning

    Winter can cause debris and leaves to accumulate around or on your AC system. Debris is responsible for minimizing the flow of air and can lead to other issues. Give the exterior casings, inner coils, and other frequently used parts a rigorous cleaning before the wind gets chilling. Another important air-conditioning component you should thoroughly clean is the outdoor condenser.

  4. Don’t Forget The Ducts

    Dirt and debris, dust mites, pet dander, pollen, and other allergens can get stuck in the air ducts, contributing to a dangerous living environment. You are likely putting yourself at risk for health issues (e.g., hay fever flare-ups) if you are sensitive to allergens or contaminants. Therefore, it is hard to overlook the importance of getting your air ducts clean. Cleaning your ducts can also help reduce odors in your home.

  5. Cover Your Unit

    There are two benefits associated with a covered air conditioning unit: (1) keep your system from freezing rain, winds, and animals; and (2) prevent thieves who might be looking for air conditioning units to ransack for copper wiring. Your local store will give you lots of options to choose from.

  6. Change Worn-Out Components

    If you want your unit to work smoothly and efficiently year-round, most especially in the cool months, now is the right time to replace parts that are worn-out or have outdated. Assuming the AC you own is more than five years old already, have it inspected by an HVAC professional. Any parts or damages will be detected to do replacement before a major issue arises.

  7. Maintain A Consistent Temperature

    As much as possible, avoid big temperature changes. Otherwise, you will notice a big spike in your energy bills. Consider using a ceiling fan or turning off your AC during cool nights or days. Aside from reducing the work of your air conditioning, it is also an excellent way for improving your overall comfort.

  8. Schedule A Maintenance Check Up

    Preventive maintenance is one of the great solutions to protect air conditioning units from potentially expensive repairs. Spending a little bit now on an annual maintenance checkup means saving plenty by avoiding costly repairs later. Most companies or AC service providers offer new duct systems and replacement of air conditioning and heating equipment aside from preventive maintenance, so if there is an issue, they can easily get to work.

Winter is a perfect time to get warm inside and do things you love most, such as cooking your favorite food and having movie marathon – all with the warm air coming from your HVAC unit. Take advantage of the season while it lasts!



What Temperature Should I Set My Thermostat To While Away?

What temperature should you set your thermostat to while away? Well, that depends, mostly on preference and goal. Here are some tips from the professionals at EasyBreezy A/C.

Before we begin, the most important step is…

Invest In A Programmable Thermostat

There is actually no perfect home temperature no matter what the season is or whether you are away or not – that mostly depends on the demands of homeowners. But if you want to make adjusting temperature less hassle on your part, consider what a programmable thermostat can do for you.

It enables you to set different temperatures all through the day, depending on various factors such as when you are home, when the house is empty, the time of the day, and the weather condition. Simply plug it, the programmable thermostat allows you to “set and forget.” You can even control the temperature through your tablet or smartphone with most programmable thermostats sold these days.

Now the tips:

What should be your thermostat setting when you are away for business or a holiday vacation?

Well, you do not want your unit to be completely off with no air movement. BUT, you also do not want to leave the AC running at full blast, cooling the house when no one is there to enjoy it. There is a Goldilocks zone in the middle.
If your trip is in the middle of summer or even in the early warmer months, set your thermostat closer to 80° F. This will help you to save energy (and subsequently, money on your cooling bill) while you are away. If you have a programmable thermostat, you don’t have to wait for your home to cool down until after you get home. Adjust the thermostats settings so that it begins to cool off about an hour before you get home.
As for vacations in the winter, Florida doesn’t get many consistently cold days – at least not until January, so set your thermostat to auto so it can switch to heat or cooling as needed and keep the cooling around 78° and the heat around 64°. Since you won’t be home, it won’t need to kick on as much while you are gone.

What temperature should I set my thermostat in the summer and spring?

During summer and spring seasons, the temperature increases in the home just as it does outside, which can make it extremely uncomfortable without the air conditioner running. However, it can be costly for keeping our home cool during the extreme heat of Florida summer. This is where thermostat setting comes very beneficial as it can help us save more in our energy bills but still manage to be comfortable while at home.
When you’ll only be gone during the day, you can program your thermostat to adjust while you are gone to a few degrees warmer and then begin cooling again when you are on your way home from work. Just like while on vacation, there is no need to have heir air conditioner working overtime when you aren’t home to enjoy it.
When you are home, your temperature can be set to personal preference but if your cooling bill is too high, consider rising your normal temperature up 2 or 3 degrees. Even a small change can make an improvement on your energy bill.

What temperature should I set my thermostat in the winter and fall?

The ideal temperature range during winter is from 60-65 °F, though, most people prefer 68 degrees.
The best temperature during the winter will really be your preference but if cutting down costs or energy usage is your goal, then lowering the temperature for your heater will help lower your bills.



Why Does My Air Conditioner Leak Or Drip Water?

Most of the time, people rarely give their air conditioners much thought until there is a problem and it needs troubleshooting. One common problem with air conditioning unit is they end up leaking water inside. If your air conditioner has this problem, then here is some information you should know about the cause, and how you can fix it.

Humidity in the Air

Humidity is the amount of water in the atmosphere. The function of an air conditioner is to remove the moisture in the air. This then reduces the humidity levels in your home and can be the cause of the water you see “leaking” from your unit.

Generally, your air conditioner producing water is a good sign – you’ll likely see the water draining out of the back of the AC unit outdoors. However, if water is not draining here, then there might be a problem – like it is draining where it shouldn’t or is clogged in your unit.

Causes Of Leaking Air Conditioners

Air conditioners usually produce water as part of their operating process. It comes out of a specific drain line. However, if the water is coming from somewhere else, then your air conditioner is leaking and will need fixing. Some of the causes of a leaky air conditioner include:

Clogged Drain Lines

Air conditioners produce a lot of water, and they usually discharge it down the drain line. If the line is clogged, the water will end up backed-up inside. A clogged drain line can cause water to leak out of other areas. If your air conditioner is leaking water indoors, the first thing you want to do is unplug it (water and electricity don’t mix). Next, you’ll want to inspect the drain lines and clear out any debris that may be clogging it. If you are the DIY-type, then you can use a shopvac to clean out the drain line. If not, troubleshoot with another possibility below or contact an AC repair company, like EasyBreezy A/C to help you get your air conditioner back to normal.

If you have a really old unit that is still going, it may drain into a pan. Check to ensure the pan has not rusted or damaged as these effects can cause leaking.

Icy Coils

If the water is not draining properly, it can back up over the cooling coils. As a result, the water freezes over the coils. To check for this use, turn off your unit and open the cage to inspect the coils. This can be complicated for homeowners unfamiliar with their AC unit – if so, give us a call to solve your leaking air conditioning issue.

Dirty Air Filter

Now… we put this down here at the bottom, because we know that you regularly change your filters, right?  We have found that dirty filters are the number one cause of water leaks in your air handler. If it has been several months since you changed your air filter, it COULD be the cause of the AC leaking.  When the air conditioning’s air filter is dirty, it inhibits proper air flow over the evaporator coils. As a result, the coil gets too cold and freezes – and when it thaws, it leaks.

Call An Air Conditioning Pro

If you cannot find the source of your leak or your troubleshooting methods have not resolved the AC leaking issue, contact EasyBreezy A/C to fully inspect your unit for the source of your problem. Our skilled and professional AC technicians will help your air conditioner get back to normal.



Why Would An Air-Conditioner Stop Working?

We have come in an age of a constantly moving forward economy. The living conditions that were only for the privileged rich in the 1960s are now considered as the basic necessities for everyone. One such necessity is air conditioning. Today, almost everyone in Florida has an air conditioner system in their homes in order to cope with the blazing hot summers. Failure of an air conditioner can cause a lot of stress and panic for repairs. An air conditioner can stop due to many reasons, as simple as of a fuse tripping off. Other common causes for an air conditioner to stop working include:

  1. Mechanical issues
  2. Air Filters Getting Clogged
  3. Your Refrigerant Is Low
  4. The Unit Has An Old Thermostat

Mechanical issues

An air conditioner has 5 components:

  • Fan
  • Compressor
  • Evaporator Coil
  • Condenser Coil
  • Expansion Valve

There are two units of the AC: One inside the home where the fan blows air through the cooling evaporator coil and cools the house. The compressor, condenser coil, and another fan on the outside vent the warm air. The expansion valve controls the regulation of the refrigerant that moves between the evaporator coil and the condenser coil.

Any issues related to any of this machinery can keep your air conditioner from functioning normally. It is advisable to have a yearly checkup to prevent any of these from becoming faulty and replacing a single component is as costly as purchasing a new air conditioner.

Air Filters Getting Clogged

One of the most common reasons because an air conditioner stops working is because of failure to replace the worn-out air filters on time. A clogged filter obstructs the flow of the cold air and decreases the cooling of your house. So, if you are experiencing even a little less cooling, have your air filters checked before it creates any damage to your air conditioner. It can cause your unit to leak water and also result in a clogged drain line. Here is an article about why your air filters may be getting dirtier faster.

Your Refrigerant Is Low

Cooling can’t happen if the refrigerant is low. The amount of refrigerant in your unit must exactly match with the amount specified by the manufacturer. There are two possibilities why your refrigerant is low – the refrigerant was not added properly when the unit was first installed or more commonly, your unit has developed a leak. Leaks are t reason for low refrigerant about 90 percent of the time. That is why you must have regular checkups of your air conditioners by authorized technicians to check for potential leaks and stop them before they occur.

The Unit Has An Old Thermostat

It is common to upgrade an AC unit and not a thermostat – or vice versa. Often times the thermostat is not properly calibrated with the air conditioner. As your thermostat ages, is ability to keep up with your cooling needs can diminish as parts and wires wear out. This is one reason why we, at EasyBreezy A/C, provide a new thermostat with every install.



What To Do When Your Server Room Cooling Fails

In today’s fast-growing technological world, the server room/ data center is considered the backbone of daily organizational operations. Server room hosts their databases, network systems, servers, backup hardware and in some large companies, even the communication system is installed as well. All these devices are constantly operating and produce a great amount of heat for which state of the art cooling systems are installed to keep the steady room temperature in order to ensure the proper function of the server room devices.

In the worst case when cooling system of the server room fails, it could be very costly for the organization if not fixed with in time and it can result in damaging of the hardware installed or even the loss of their precious data. Now when the server room cooling failure occurs there is need to take decisive and swift action.

The right actions in this regard will help the organization keep running longer and also to avoid any further serious failures. In this article, below are few helpful tips that will keep the IT administrators out of a bind if the entire cooling system has a failure.

Call A Professional To Fix

The first and most important step is to know about your maintenance team. The first call you will make should be to your HVAC engineer at EasyBreezy A/C. Make sure to explain the problem in detail so that all necessary (or possible) parts and tools will be brought along for all possible scenarios and causes.

Understand And Anticipate Critical Temperature Values

You should be familiar with the duration for which server room devices will last before the room temperature reaches its critical values. Perform a heat stress test on your current environment in order to understand and anticipate the time for which your server will last before the critical value of operating temperature.

Time To Arrange Portable Cooling System

If you are left with only few hours before the critical values are reached, get ready to make use of your portable cooling system if you own one or make arrangements for renting. These financial sacrifices will save you from costly consequences if you can’t get the temperature back down before the data cooling system technician arrives.

Turn Off Unnecessary Hardware

Some types of servers, like development servers or test servers, consume more power and thus produce more heat. Such servers are not required to run during production and can be turned off to reduce heat production. Any other servers or systems that are not important should be shut off to minimize heat production.

Make Arrangements For An Large Fan

If server room temperature rises, approaching critical temperature values, open the doors to the server room and windows, if there are any. Use (by renting or from your company supplies) any kind of fan to help pull the hot air out of the room. The best way to do this is to face the fan in the doorway, facing out so that it is sucking the warm air from behind it and blowing it out of the room.

Backups And Plan B

Last but not the least, when dealing with cooling system failure in your data room or server room is to make sure that you have your backups prepared and maintained ahead of the time. When these backup systems are set up in advance, it will help you to successfully deal with cooling issues without losing any data or downtime.



DIY AC Solutions

Sometimes, little things can make your air conditioning unit stop working – things that aren’t worth paying an AC repair company to check for or fix. If, however, you check each of these things and they have not solved your problem, then you can call in an AC pro to take it from there!

The following are the simple and yet effective steps to follow to repair air conditioners:

  • Turn The Power Off: No, this isn’t an IT blog, but yes, this can help with your air conditioner too. If your AC is having trouble or won’t kick on, then the first thing you should do is to turn it off at the power source (not the thermostat). After switching off the power, wait a few moments for the system to complete shut down and then resume power. Sometimes a little reboot is all that is needed to get things acting normal again.
  • Fan Motor Must Be Oiled And The Condenser Cleaned: AC failure tends to have common culprits – the fan and the condenser. The fan motor should be lubricated using oil that is specified by the manufacturer. The condenser has to be cleaned with the use of a soft bristled brush to remove all dust that has accumulated. Wear-and-tear is one of the leading causes of AC issues.
  • Check To See That The Air Filters Are Clean: This is one of the most comfortable air conditioner DIY tasks but is often the cause of many problems. Since the air filters are responsible for cleaning the air before it travels through your cooling system, it should be clean. If it is a dirty filter, it will fail to caputer the dust and debris in the air that can easily clogg up your air conditioning system and cause problems. The recommended time frame is replace your air filter (or clean a reusable filter) is every three months. If you live with smokers, in a home prone to dust, have pets or a sensitivity to natural allergens, then you should change your filter every one or two months.
  • Be Sure To Check That The Thermostat Is Appropriately Working: If you have a digital thermostat, working batteries are essential since they power the unit. Most digital units will show in the panel if the batteries are low and even remind you of when to change the air filter. If the thermostat is in the unit itself, as in window units and some ductless systems, check that no obstructions or debris are affecting the sensor.
  • Condenser Coils Have To Be Cleaned, Too: The next step would be to make use of a garden hose to clean the condenser coils. Be sure that the coil guard is removed before being sprayed with water.

Maintaining and extending the life of an air conditioner is something that any homeowner can do. With regular care, your air conditioner will work well all year-round. Don’t forget to schedule routine, annual maintenance from your local AC technician. At least once a year your AC and heating system should get a once over to check on moving parts, lubrication, and overall functioning to see if parts need replacing or cleaning.



How Cold Should A Server Room Be?

In the present world if we look around, data is considered the blood of countless businesses and server rooms work as a heart to keep it flowing. This clearly states that server rooms play a vital role in keeping businesses alive in today’s fast-growing world and in order to achieve the desired productivity level a malfunctioning of servers cannot be tolerated.

Most commonly when it comes about the server protection first few things that hit our mind are network threats, Spyware, and viruses. However, for a proper functioning of server a there are also considerable cooling requirements, which if not controlled and monitored properly as per required standards; can cause a significant damage to your business productivity.

Moreover, in the worst cases, this can even result in damaging or destroying your valued equipment and data.  Now the question is what are cooling requirements for a server room? How cold should a server room should be? And what causes the increased temperature of server room? Well to answer all those questions we are highlighting most commonly practiced industry recommendations.

For businesses that rely on data, there is need of server that is constantly online. Now when the server is constantly online it is continuously producing heat, increasing the temperature of server room, as a result the overall system will overheat. Most high-end system these days have protection system against overheating that shutdown the system when the temperature is too high, but it is not case for all systems. Therefore, to ensure well-maintained temperature of you server room you are in need to take proper precautionary measures.

The simplest and yet often ignored practice is the proper arrangement of your servers to obtain optimum efficiency of air conditioning. In this practice, one must ensure that the cold air enters the front and is ejected through its back. In addition, doors of the server room must be kept closed and in case of the event when your primary air conditioning system stops working, there must be a backup system to keep the things cooled.

What are the industry standards?

According to the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), keeping the server room temperature between 77 ℉ to 81 ℉ is good for the trouble-free functioning of server room devices.

In addition, it is also needed to maintain relative humidity in server room between 41% to 50 %, otherwise there will be condensation if there is too much moisture.

Server rooms can operate safely between temperature ranging from 64.4 ℉ and 80.6 ℉ based on your needs and location. For IT administrators or service providers located in colder climates, American Society of Heating, Refrigerating and Air-Conditioning Engineers states that “Class 1 and 2 equipment shouldn’t operate at temperatures lower than 18 degrees Celsius, which converts to the relatively mild 64 degrees Fahrenheit. The standard for Class 3 and 4 equipment is a bit looser at 5 degrees Celsius, 41 degrees Fahrenheit”.

In short, climate control is the foremost responsibility of server room staff in both cold and hot climates to maintain a steady temperature with a goal to avoid overheating of server room devices, condensation and presence of static charge due to low humidity levels.



Why Does My AC Smell?

Common Air Conditioning Odors And Their Causes

Air conditioning falls under the category of basic necessities (like food, shelter, and water do) given how important it is in a home in the present era. However, unlike most other necessities, air conditioners require maintenance and if not kept up with. Luckily, air conditioning systems typically give off warning signs when something is not right – poor air flow, warm air instead of cold, buzzing or other odd noises, and smells.

The following are some of the common smells that you might experience when something is wrong with your air conditioner, along with the likely culprit.

Smell musty or smell like mildew

This is a result of excessive humidity in your AC system along with the presence of mold or mildew in the ducts, clogged drain lines, or stagnant water in the drip pan. To solve the problem of this particular smell, you usually do not need help from expert. Check where the drip pan or wherever the AC releases the moisture pulled from the air for standing water or poor drainage. Also check the drain pipe – if it is dry, then there is likely a clog somewhere. Be sure to change all of the intake filters and continue to do so regularly. If your home is prone to humidity, install a humidifier in one of the main rooms to help pull moisture from the air and lighten the burden placed on your air conditioning system. If the smell persists, then your duct work may need a thorough cleaning. If you have never done this before, it is recommended to give us a call to ensure that no damage befalls your duct work or system.

Smell like dirty socks

Dirty Sock Syndrome is an actual “illness” that can affect your air conditioning system. The dirty socks smell (or gym bag, work boot, 3 day pile of wet laundry smell) is usually a product of mildew somewhere in your system. It could be in the duct work or around the evaporator coil.  Like the above smell, it is typically the cause of high humidity in the home or clogged drain pipes only stage of mildew is long past changing filters to resolve the issue. This will require an in-depth cleaning of your system.

Cigarettes

You guessed it – this smell is caused by of the presence of tobacco smoke residue in your AC system. Even if the smoker uses a designated room or part of the house for their smoking habit, the smoke can and will inhibit the air conditioning system and be filtered to the rest of the home. Change the filters more often and encourage the smoker to some only outdoors. At a minimum, better ventilate the areas where smoking is occurring by opening a window and using a fan to help circulate the air.

Acetone

The scent of acetone, or nail polish remover, is an indication that you have a refrigerant leak in your system. A refrigerant leak can not only be disastrous for the efficiency of the system, but also your health. It poses serious health hazards so if you smell this odor in your air conditioning system then turn off the system immediately and get help from an expert.

Rotten Eggs

This will only be a concern for residents or commercial offices who have gas-drive AC units. The smell of rotten eggs is a common description used when there is a gas leak. If you smell this in your house and you’re sure that it is coming from the air conditioning system, then immediately call a professional for help. Also, open the windows and turn off the appliances to avoid any spark that can result in an explosion, then wait outside for assistance to arrive.

Burning Smell

In Florida, this smell is typically not a concern. You may experience a burning smell after turning on your systems heater after it is dormant for the majority of the year. When you don’t use your heater for a long period of time dust can settle on the heating coils. When you do start using it the dust gets burned off, resulting in a burning smell. The smell will eventually dissipate and fade away.
However, if you have been running your heater for the last 24 hours and the smell has already dissipated, or you never experienced it and you now are, then the smell could be an indication of overuse. When parts are dormant and do not receive regular maintenance, they can wear out from lack of use (just like a tool in your garage that never gets used may rust). It can also be a sign of a bad or malfunctioning compressor. If you smell burning several hours after the heater is in use, then turn off your unit and contact us to evaluate your system.

Smell like Rotting Carcass

Sounds gross and the smell itself can be really disturbing and you can’t help but notice it. As the name shows, this smell is due to a bird, mouse, squirrel, or other creature dying after getting caught somewhere in your system. So, if there is a rancid, rotting smell and no other indication to its cause, you should turn off your air conditioner and contact an AC repairman. A decomposing body of a small mammal can be very harmful to your health and you don’t want your AC system to circulate it through your home.

In all cases, you can avoid, reduce, and prevent smells with routine maintenance and a whole home indoor air quality product.



How Your AC Works

There is hardly any building or car without an air conditioner these days. It has become a useful component of houses, homes, vehicles, and so on. With each passing day, air conditioning is becoming more and more of a necessity.  Although everyone enjoys a cool room, not all know how the air is cooled. While this may seem like something only a professional air conditioning repair company may need to know – understanding how something works will help you identify any issues that arise and whether they can be simple DIY AC fixes or require professional AC repair.

Parts Of An Air Conditioning Unit

To understand how an air conditioner works, you’ll need to know the four major components of an air conditioner. These parts are:

  1. Evaporator

The evaporator collects heat from a space via a refrigerant gas. The evaporator coils are where the absorption of heat by the liquid refrigerant takes place, and after the absorption process, the liquid evaporates into a gas.

An additional function of the evaporator coil is to dehumidify the room by drawing out moisture from the incoming hot air.

  1. Compressor

As the name suggests, this is the area in which the compression of the gaseous refrigerant occurs. By increasing the pressure of the gas, the temperature rises. The gas is the transferred to the condenser for conversion.

  1. Condenser

This is where the gas refrigerant is converted back to liquid, and the heat I absorbed from the air is expelled outside.

  1. Expansion Valve

The valve is positioned between the cooling coils of the evaporator and the hot coils of the condenser. Sometimes referred to as the throttling device, it monitors the amount of refrigerant that moves into the evaporator.

How An Air Conditioner Works

When you turn on an air conditioner and select your desired temperature, there is a sensory device in the AC that senses whether there is a difference between the temperature of the room and the one selected by you.

If there is, then warm air is taken into the air conditioning system through an intake vent, typically located at the base of the indoor unit or in a central part of your home. Some homes have multiple intake vents. The warm air then follows through your ducts and over the evaporator coils containing the liquid refrigerant. The refrigerant absorbs the heat from the air and turns into hot gas.

The hot refrigerant gas is sent to the compressor which is on the unit installed outside. The gas is compressed, further increasing the gas’s temperature.

The now high-temperature, high-pressured compressed refrigerant gas is then transferred to the condenser which cools the hot gas back into a liquid. The heat of the gas is released into the open air through metal fins in your outdoor part of the AC unit.

The liquid travels through an expansion valve and back into the evaporator as a cool liquid refrigerant. The air passes over the evaporator coils and cools before being blown back into you’re your home.

The process is repeated until the desired temperature is achieved.
