Why is My A/C System Blowing Hot Air? 

Aug 11

You bought your air conditioner with one thing in mind: to keep you cool during those hot summer days. But what happens when your A/C system starts blowing hot air? While it may seem like your unit is malfunctioning, there are a few potential explanations for why this could be happening.

Below are some of them:

Your A/C system is not receiving enough power. 

For your air conditioner to function at its best, it needs to have enough power running to it. But sometimes, A/C systems can trip breakers or overload circuits, which is why you are left stuck with the hot air.

As a troubleshooting tip, you can reset the breaker. All you have to do is simply turn off the power to your air conditioner at the breaker box and then turn it back on. If this doesn't work, you may have a more serious issue with your electrical system, and you will need to call the pros for immediate A/C repair Signal Mountain, TN.

The refrigerant levels are low. 

The refrigerant is what helps your air conditioner to do its job properly. But the copper coil that holds the refrigerant can sometimes develop a small leak, causing it to slowly escape. When this happens, it can no longer reach your comfort needs, and you will start to notice that your home is not cooling off as much as it used to.

What are you going to do about it? Instead of continuing to use your cooling system with low refrigerant, you need to call for A/C repair Signal Mountain, TN so that a professional can come out and recharge your system right away before any additional damage is done.

The air filter is dirty. 

What if your air conditioner is no longer tripping the breaker and the refrigerant levels seem to be okay, but you are still left feeling hot and sticky? It could be that your filter is in need of replacement.

When the filter becomes full of dirt and debris, it can no longer do its job of allowing air to flow freely through the unit. This puts unnecessary strain on your system, causing it to work harder. To prevent this from happening, be sure to check your filter monthly and replace it as needed.

The evaporator coils are frozen. 

The evaporator coils are responsible for removing the heat and moisture from the air in your home. They do this by absorbing the heat and releasing it outside. But sometimes, the coils can freeze over, which prevents them from doing their job.

One way to tell if your evaporator coils are frozen is if there is ice build-up on them. If you see this, turn off your air conditioner and allow your unit to thaw out completely before turning it back on. You may also need to call for A/C repair Signal Mountain, TN so that a professional can take a look and make sure that there isn't anything else going on.

The thermostat is set incorrectly. 

Another potential cause of your air conditioner blowing hot air could be that the thermostat is set incorrectly. The thermostat is responsible for telling your cooling system when to turn on and off. If it is set too low, it could cause your unit to run continuously, which can lead to a frozen evaporator coil. To fix this, be sure to keep your thermostat set to a temperature that is no lower than 78 degrees.
