Why Is My Air Conditioner Blowing Warm Air?
Warm air blowing from your vents can be a sign that something is wrong with your air conditioner. Here are a few common reasons why your air conditioner may be blowing warm air. Some reasons are an easy do-it-yourself fix while other diagnoses will require the aid of a professional. Contact our office if you are unable to resolve your warm air issue.
The Thermostat Is Set Incorrectly
This may seem like an unlikely scenario but too often we have been called only to find this at the root of the problem. Many thermostats now are touch screen and settings may be changed if they are bumped into. Make sure that the thermostat is set to “cool” and not “heat”. Also check whether the thermostat is set to the “on” or “auto” setting. The “on” setting will keep the fan blowing air through the home (to circulate it), even when the air conditioning unit itself is not currently cooling. The air being circulated through the vents may feel warm or not as cool as the rest of your home but the air has not actually been warmed by your unit and is normal. The “auto” setting will only circulate air as the unit is cooling and the fan will stop when the ac completes a cooling cycle.
Restricted airflow can cause your cool air to warm up as it fights to be circulated through your home. Restricted airflow can cause a number of issues within the air conditioning system, like causing your compressor to freeze up, and should be resolved as soon as possible. Restricted airflow is usually a sign of poor maintenance. Check your air filter to see if it needs replacing; they should be changed every 1 to 3 months, sooner if you run your AC more often or have pets. You should also have regular maintenance performed on your unit, at least once a year, to keep your coils clean and all gears moving smoothly.
The Outside Unit Isn’t Working Properly
Your air conditioning system is comprised of two units. The unit located outside on the side of your home and an indoor unit that is either in a hidden closet or in your attic. Your indoor unit blows the cooled air through your home but if the outside unit isn’t working properly, it won’t be able to blow cool air. Some issues the outdoor unit may be having are:
