Summer is in full bloom and surely you want your air conditioner to perform the one primary task it is built to do – blow lots of cold air throughout your living space. However, when your AC is blowing warm air not only does the atmosphere in your home become quite sticky and uncomfortable, but the overall situation can be quite an irritation on everybody. What actually causes an air conditioning system to blow warm air and is the problem easily fixable by the right HVAC professionals?
CHECK THE THERMOSTAT
One of the very first things you need to do when warm air is blowing from your AC system is to check your thermostat. Sometimes the thermostat setting can be inadvertently moved to the heat setting, causing the hot air to blow or can even be in the on position rather than the auto position which will cause the system to blow air consistently, and certainly not always cool air. Be sure your thermostat is set to the auto and cool setting so that it can operate effectively and efficiently all day and night.
CHANGE THOSE AIR FILTERS
If you have failed to change the air filters in your cooling system, then during the scorching hot summer months you may find your AC is blowing warm air rather than the expected cool air. You should change your filters monthly otherwise they will become extremely dirty and clogged, blocking the air circulation and ultimately causing warm air to blow. In addition, you should ensure that the evaporator coils are clean. This is a task you can easily perform yourself by turning the AC system off, removing the outer panel, and by using a soft bristle brush, water and a mild detergent, clean the coils with compressed air. If you are not comfortable, however, be sure to contact the skilled professionals here at M&A HVAC Services, LLC to handle the task for you.
HAVE YOUR DUCTWORK INSPECTED
If your system ductwork has become damaged or disconnected it can easily result in warm air blowing. If the ductwork is in need of sealing this will allow the hot air to get into your home. Be sure to call one of our professional technicians to identify the problem with your ductwork and provide either adequate repairs or replacement ducts.
HOW ARE THE REFRIGERANT LEVELS?
If your AC system has a refrigerant leak the system will stop blowing the typical cold air and instead you will note that your AC is blowing warm air. There are a few indicators that the refrigerant levels are too low such as ice forming on your AC unit, or you may notice a screeching sound coming from the system. If you believe your refrigerant levels may be low or you have a refrigerant leak, call on one of our professionals immediately to resolve the issues since refrigerant can actually be harmful to the overall health of your family.
DON’T FORGET TO CHECK THE OUTSIDE CONDENSER

Condensor Fan
If the outside condenser has something blocking the air flow generated by the condenser coils such as debris, dirt or outdoor growth, it will not be able to blow cold air. For this reason, it is important to properly maintain your outdoor condenser so as to avoid air flow problems.
