Why Is My AC Blowing Hot Air?

One of the most frustrating issues you may encounter with your home air conditioning system is that it continues to blow hot air. Fortunately, there are some simple fixes you can try to remedy the situation. However, in some cases, it may be necessary to call us for prompt repair service.

Thermostat Settings

The first reason your AC unit may be blowing hot air is that you have the wrong setting on your thermostat. Check to see what your blower fan is set to. If you have your blower fan set to ‘on’, it will constantly run, even when your air conditioner isn’t. This can cause the air coming out of your vents to feel warm at times when your air conditioner isn’t running. Instead of having your blower fan set to on, switch it to auto. This will ensure the blower fan only runs when your air conditioner is working.

Dirty Air Filters

Another simple reason your AC may be blowing hot air is that its air filter is excessively dirty. Air filters typically last for between one and three months. When the filter gets clogged with debris, it can restrict the operation of your cooling system. This can make it feel as if lukewarm air is coming out of your air vents.

This is another easy fix that you can do on your own. Remove the existing air filter from its housing and hold it up to a light. If you can’t see through the filter, it’s time to replace it with a new one. Ensure you choose a filter with the same dimensions, as it’s imperative to the proper functioning of your cooling system.

Refrigerant Leaks

As your air conditioning system works, it removes heat from the air via a substance called refrigerant. As hot air passes over the evaporator coil in your indoor air handler unit, it naturally transfers into the low-pressure refrigerant. This refrigerant gets pumped outside to the outdoor condenser unit, where its heat naturally transfers to the lower-pressure air that’s blown over it.

Unfortunately, if your system’s refrigerant level becomes too low, it will be unable to remove enough heat from your home adequately. This can allow the air coming out of your vents to remain relatively warm, rather than cool. You’ll need to call us for prompt air conditioning repair near Roanoke, VA if you suspect you have a refrigerant problem. We can easily work to locate the source of the leak, repair it, and add more refrigerant to your AC unit to restore its normal functioning.

Electrical Issues

Another reason your AC unit may not be cooling properly is an electrical issue. The most common is with your outdoor condenser unit. It’s essential to note that your indoor air handler unit can continue to operate even if your outdoor condenser unit is turned off. The subpanel of your outdoor unit can easily trip without you even realizing it. This is a simple fix, as all you need to do is reset the circuit breaker for your outdoor condenser unit.

Getting Prompt Repair Assistance

When you first notice a malfunction with your cooling system, it’s necessary to call us for prompt repair service. You never want to continue to run your system, as it will simply lead to more damage. This can ultimately be more expensive to repair. Instead, opt for shutting your unit completely off when it malfunctions and let our knowledgeable HVAC technicians handle repairing it for you. We can do repair work that’s covered under your unit’s warranty so you can pay less out of pocket.
