When the temperature starts to rise outdoors, you expect your air conditioner to keep your house comfortable. Your AC may be on, but the air blowing from your vents appears warm.
Here are the most common reasons why this happens and what you can do to repair it. If you require air conditioning repair in Columbus, the Experts at Service Experts Heating & Air Conditioning can support you. Like always, all our AC repair labor is supported by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Examine the fan setting. If it says “on,” the fan will blow even when the AC compressor isn’t running. This is okay, but your energy expenses will be bigger if the fan operates all the time. Adjust the setting to “auto,” and the blower will only run when the compressor is on. This also means the air radiating from the vents will repeatedly seem cold.
2.Filter is Clogged
The HVAC air filter traps airborne particles that can ruin your heating and cooling equipment. If it gets too obstructed, it can lower airflow. This limits how much warm air flows over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, blocking the cooling cycle from happening. To prevent this, put in a new filter every month or as advised by the manufacturer.
Refrigerant is essential for air conditioning. It shifts 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 poorly and may not produce sufficient cool air. It can also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle completely. You’ll need assistance from an HVAC technician, like one from Service Experts Heating & Air Conditioning, to fix any refrigerant problems.
4.Condensing Unit is Dirty
The outdoor component of your AC unit is referred to as a condenser. This is essentially a giant heat sink that removes hot air from your house. If the metal fins are covered with dirt, the condenser can’t work efficiently. Wash down the equipment to clear accumulated debris and trim back shrubs to make sure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Out
While you’re checking the condenser, make sure the large fan at the top of the equipment is working. If the fan motor has gone out, the condensing unit can’t exhaust heat appropriately, and your air conditioner might start sending warm air into your house.
Pay attention to the sound of the compressor running inside the condensing unit as well. This is the heart of 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 home. If the compressor fails, you’ll probably need to buy a new unit and schedule air conditioning installation.
