Why Is My AC System in Fairfax, VA, Blowing Hot Air?

If you own a home in Fairfax, VA, you know the importance of your cooling system and why it must remain in top condition. Blowing hot air is the most frustrating problem that can arise with air conditioning. Here are some of the possible reasons your AC system is blowing hot air:

Dirty Air Filter

Over time, the filter in your air conditioner can become clogged with dust and dust, restricting airflow through the system. When this happens, your AC system will start blowing hot air.

You need to check your filter at least once a month and clean or replace it as needed. Most experts recommend not going any longer than three months without a replacement.

Low Refrigerant Levels

Refrigerant is the substance that cools the air in your AC system, so if there isn’t enough, the air that comes out will be hot instead of cold. Low refrigerant levels can be caused by a leak in the system, which can be challenging to detect without professional help. If you suspect your AC system has a refrigerant leak, contact an HVAC professional in Fairfax, VA, to diagnose and repair the problem.

Faulty Thermostat

Sometimes, the problem with your AC system isn’t with the air conditioner itself but with the thermostat controlling it. If your thermostat is faulty or malfunctioning, it may not send the right signals to your air conditioner, causing it to blow hot instead of cold air.

Ask an HVAC service technician to troubleshoot the problem and apply the necessary solutions. This might mean replacing the batteries or even the whole thermostat.

Don’t suffer in the heat while you try to figure out what’s wrong with your air conditioner. Contact us at E.M. Logan Inc. to have one of our experienced service technicians determine the problem and resolve this and any other HVAC issues you may have.
