When the temperature starts to rise outside your home, you rely on your air conditioner to keep your home cozy. Your AC might be running, but the air issuing from your vents feels warm.
Here are the most common reasons why this happens and what actions you can take about it. If you need air conditioning repair in Belleville, the Experts at D & K Heating Service Experts can help. Like always, all our AC repair service is upheld by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Incorrectly
Examine the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t running. This is okay, but your cooling costs will be more expensive if the fan runs all the time. Adjust the setting to “auto,” and the blower will only operate when the compressor is on. This also means the air issuing from the vents will always feel cold.
2.Filter is Clogged
The HVAC air filter catches airborne particles that can ruin your heating and cooling system. If it gets too clogged, it can lower airflow. This restricts how much warm air moves over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, preventing the cooling cycle from happening. To avoid this, put in a new filter each month or as suggested by the manufacturer.
Refrigerant is essential for air conditioning. It changes from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If the refrigerant is low, your air conditioner will operate poorly and may not produce adequate cool air. It may also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle fully. You’ll need assistance from an HVAC tech, like one from D & K Heating Service Experts, to solve any refrigerant issues.
4.Condensing Unit is Dirty
The outdoor part of your AC equipment is called a condenser. This is essentially a big heat sink that transfers muggy air from your home. If the metal fins are laced with yard debris, the condenser can’t work efficiently. Hose down the unit to clear debris that builds up and cut back vegetation to confirm the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Out
While you’re checking the condenser, ensure the big fan near the top of the system is running. If the fan motor has gone bad, the condensing unit can’t break up heat properly, and your air conditioner might start circulating warm air into your home.
Listen for the sound of the compressor running inside the condensing unit too. This is one of the most important parts of your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can collect more warmth when it moves back into your house. If the compressor fails, you’ll likely need to get a new air conditioner and schedule air conditioning installation.
