Why is my air conditioner blowing warm air?

One of the most frustrating things in the world is when you go to turn on your air conditioner on a hot day in the summer, only to be greeted by warm, stale air coming from your air conditioner vents.

Having warm air coming out of your air conditioner can be uncomfortable, even preventing some people from being able to sleep at night.

One reason your air conditioner might be blowing warm air is your air filter. Air conditioner air filters can become clogged over time with dust and debris, and if the blockage becomes too severe, it can prevent your air conditioner from properly circulating and cooling the air in your home. Many HVAC professionals recommend changing your air filter every 30 to 60 days, especially if you have pets. Another reason your air conditioner could be blowing warm air is because of a freeze. If your air conditioner has frozen up, then the coolant cannot circulate throughout the system properly, resulting in your unit blowing warm air into your home. Giving your air conditioner proper time to defrost could let the coolant be able to redistribute the heat from your home in order to cool the air inside your home. Another reason your air conditioner is blowing warm air could be because you are running low or out of coolant. If your HVAC system doesn’t have enough coolant, it will be impossible for your unit to cool the air inside your home. It is important that a professional HVAC technician is the one dealing with the coolant in your system, as HVAC coolant can pose a risk to the handler as well as the environment.
