When the temp begins to rise outside, you depend on your air conditioner to keep your house comfortable. Your AC may be running, but the air coming from your vents appears warm.
Here are the most frequent reasons why this occurs and what you can do about it. If you have to have air conditioning repair in Nashville, the Experts at Donelson Air Service Experts can support you. Like always, all our AC repair work is upheld by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Incorrectly
Look at the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t going. This is okay, but your utility bills will go up if the fan is on frequently. Switch the setting to “auto,” and the blower will only work when the compressor is on. This also means the air coming from the vents will repeatedly appear cold.
2.Filter is Clogged
The HVAC air filter catches airborne particles that can wear out your heating and cooling system. If it becomes too obstructed, it can restrict airflow. This restricts how much warm air moves over the indoor evaporator coil. If the refrigerant moving through the coil becomes too chilled, it freezes, preventing the cooling cycle from taking place. To stop this, put in a new filter each month or as suggested by the manufacturer.
3.Insufficient Refrigerant
Refrigerant is the key to air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will run badly and may not create adequate chilled air. It may also lead to a frozen evaporator coil, which as previously mentioned, stops the cooling cycle altogether. You’ll need help from an HVAC pro, like one from Donelson Air Service Experts, to fix any refrigerant issues.
4.Condensing Unit is Dirty
The outdoor component of your AC system is known as a condenser. This is essentially a big heat sink that removes muggy air from your residence. If the metal fins are laced with dirt, the condenser can’t do its job. Hose down the unit to clear built-up debris and trim back vegetation to make sure the condenser can “breathe.”
5.Condenser Fan or Compressor has Gone Out
While you’re inspecting the condenser, confirm the big fan near the top of the system is running. If the fan motor has gone bad, the condensing unit can’t exhaust heat like it should, and your air conditioner might start circulating hot air into your residence.
Take time to hear the compressor running in the condensing unit as well. This is what drives your air conditioner, as the part reduces the temperature of the refrigerant. Then, the refrigerant can trap more humidity when it moves back into your house. If the compressor goes out, you’ll typically need to buy a new system and book air conditioning installation.
