Are you experiencing problems with your air conditioner blowing warm air?
Air conditioning units operate solely on the need for efficient airflow, temperature conversion, and air redistribution.
Air conditioners are complicated machines, and unfortunately, many kinks can arise and cause malfunctions in the cooling process.
There is nothing more frustrating than coming home on a sweltering day, only to discover your HVAC system is no longer blowing cool air as it should be.
After all, your air conditioning unit is on and blowing air through your vents, so why isn’t it cooling?
Although the thermostat is set to 70, your indoor temperature reads 80, and even worse, your home feels every bit of 90 degrees!
So what’s going on?
How can your air conditioner be working, but not working at the same time?
In this article, we will go over a few reasons why your air conditioning unit may be blowing warm air.
Getting frustrated is one of the first things most people do when their HVAC system isn’t working, and rightfully so.
But before you let your AC troubles ruin your day, be sure to check your thermostat to ensure that it is, in fact, on it’s the proper settings.
You always want to make sure that your HVAC system is set to (cool) and your fan is set to (auto) for efficient performance.
In many cases, this simple oversight can be the key to all of your cooling problems.
Clear airways are an essential part of keeping your HVAC system performing correctly.
If your air conditioning unit is blowing warm air, check all of your system’s air passages for debris buildups and/or blockages.
Be sure to check for:
Air filters improve your home’s indoor air quality.
They also help minimize the debris buildup your system takes on during operation by filtering all airflow before it is cooled and distributed throughout your home.
If your air filter becomes clogged, your HVAC system will have to work twice as hard to cool your home.
A clogged filter may also cause your unit’s coils to freeze over, which will result in your air conditioning unit blowing warm air.
Be sure to change your filter and give your unit an hour or so to resume proper performance.
Your air ducts are how your HVAC system distributes cooled air throughout your home.
Without proper maintenance, air ducts can become leaky, dirty, or clogged, affecting your airflow and temperature.
It is advised that your air ducts get professionally cleaned every three to five years to prevent performance problems.
Be sure to clear your outdoor unit of any overgrown vegetation and/or debris buildup, as these may hinder your unit’s performance and disrupt your comfort.
If your unit does not seem to be crowded with vegetation or debris, you may need a professional to assess the equipment and perform proper maintenance.
Refrigerant leaks are a prevalent cause of ac units suddenly blowing warm air.
Your unit’s refrigerant plays a vital role in the cooling process.
If the line somehow develops a leak, you can expect your system to lose its cooling capabilities and blow warm air.
Signs of a refrigerant leak include:
