The long-awaited summer is here, but you can't stay in your house because your AC isn't doing its job. Instead of blowing cool air, it's blowing warm air, making it uncomfortable for you to relax in your house. That's a problem you don't want to deal with, especially during summer. Besides, what's the point of having an AC unit and it can't cool your space? 

Luckily, you can call for air conditioning repair services to diagnose the cause. In most cases, an HVAC technician can address the problem with some minor repairs. To help you understand why this problem occurs, below are a few reasons why your air conditioner might be blowing warm air. 

Low Refrigerant

Refrigerant is also known as Freon, and it's meant to last a lifetime. However, if something happens to your air conditioning system, the refrigerant might leak, and the unit will eventually run low on this vital commodity. As you well know, your AC unit can't cool air or remove humidity from your rooms if it doesn't have sufficient levels of Freon.

So, if your refrigerant is running low, you should call your HVAC technician. If the technician determines that the refrigerant is leaking, they'll repair the refrigerant lines and refill the system with more Freon. 

Duct Leakage

Another possible reason why your AC might be blowing warm air is if there is a leakage in the ductwork. If your current ductwork has been in place for a decade or so, there is a high possibility that it has developed tears and small holes, or the seams could be coming apart. This damage will allow cold air to escape before it's blown through the air vents. 

If your ductwork has an issue, you'll have to hire contractors to inspect it. Remember, the ductwork is located in areas that only professionals can access. The technicians will decide whether they'll repair, seal, or replace the ductwork depending on the extent of the damage.

Clogged Filters

Your air filters need to be in the best condition for your AC unit to work perfectly. But if you find that your AC system is blowing warm air, it is possible that your filters are dirty. If there's a build-up of dirt, dust, pollen, and other particles in your air filters, they will restrict air flow, impeding the cooling operation of your AC unit. You can solve this problem by cleaning or replacing the air filters regularly. 

Dealing with an AC unit that's blowing warm air can be frustrating. Thankfully, you can prevent that by servicing the unit regularly.
