Why is my air conditioner blowing warm air?

Nothing is more frustrating than turning on your air conditioner on a hot day, only to feel warm air blowing out of the vents.

There are a number of reasons that your air conditioner can be blowing warm air, and here are a few things you can do about it.

The first thing you should do if your air conditioner is blowing warm air is to change your air conditioner filter. Your air conditioner filter works to remove dirt, dust, pet hair, and other debris out of the air in your home, and over time, the filter can become clogged, and make it difficult for your air conditioner to properly circulate the air in your home. Most HVAC professionals recommend changing your air conditioner filter every 30-60 days, especially if you have pets. Another reason your air conditioner may be blowing warm air is because your thermostat is faulty. Older thermostats tend to break down over time, and will not be able to correctly set the desired temperature. A thermostat can be replaced quickly and easily, and is a good investment, especially if your thermostat is older than 20 years. Another reason that your air conditioner may be blowing warm air is because your HVAC system might not have enough coolant. Air conditioners use coolant to distribute heat energy from inside the house, to the outside through the condenser. If there is not enough coolant in the system, then your air conditioner will not be able to displace the heat energy accurately. A licensed HVAC professional will be able to quickly assess the level of coolant in your system and fill it if necessary. If your air conditioner is blowing cold air, contact your local HVAC provider today to get your system blowing cold again.
