Why Is My Air Conditioner Blowing Hot Air?

A good air conditioner can be one of the most important appliances in your home, especially during the summer. If it starts blowing hot air, though, it can quickly become a major problem. Below are some of the reasons why your air conditioner might be blowing warm air instead of cooling down your home.

Airflow Restriction

In most cases, an air conditioner that blows warm air does so because of some type of restriction in the airflow. For most, this will come down to a failure to change the interior air filters in your home. Depending on the brand, these filters should be changed every one to three months, and failure to do so can lead to dirt and dust clogging up your HVAC unit. Any type of airflow restriction will end up causing a fairly major issue for your HVAC unit, and unfortunately, the problems caused by restricted airflow can end up being quite significant.

Low Refrigerant

If restricted airflow isn’t the issue, you may be looking at low refrigerant levels. Every air conditioner makes use of special refrigerant chemicals to help cool the air, and in time that supply will become depleted. If you have a very old AC unit and it hasn’t been serviced in quite some time, it may have simply run out of refrigerant. More problematic, though, is when you have a newer unit or one that has been recently serviced because you may be dealing with a refrigerant leak. Refrigerant leaks due to a variety of issues are distressingly common and may cause your AC unit to stop cooling your home.

Condenser Problems

Though it might not look like it from the outside, your air conditioner is still made up of moving parts. If something gets in your condenser and blocks it, your air conditioner will not work correctly. It’s very common to see issues like overgrown plants or even birds’ nests in ill-maintained units, and the removal of the blockages can actually help you to cool down your home rapidly. It’s still important to seek out the help of an HVAC professional if you note a blockage, though, as there could be more damage than you might assume.

It’s always a good idea to work with a trusted HVAC professional when your air conditioner starts to blow warm air. Though many of the root causes of the problem aren’t all that complex, it does still take a professional to get your air conditioner back in working order.
