When the mercury starts to rise outdoors, you depend on your air conditioner to keep your residence cozy. Your AC could be on, but the air issuing from your vents feels lukewarm.
Here are the most common reasons why this occurs and what you can do to repair it. If you require air conditioning repair in Memphis, the Experts at Service Experts Heating & Air Conditioning can help. Like always, all our AC repair labor is upheld by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Wrong
Look at the fan setting. If it is switched to “on,” the fan will operate even when the AC compressor isn’t running. This isn’t a problem, but your cooling costs will go up if the fan operates constantly. Adjust the setting to “auto,” and the blower will only operate when the compressor is on. This also means the air coming from the vents will repeatedly feel cold.
2.Filter Need to be Changed
The HVAC air filter traps airborne particles that can damage your heating and cooling units. If it gets too obstructed, it can restrict airflow. This reduces how much warm air goes over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, stopping the cooling cycle from taking place. To prevent this, change the filter each month or as recommended by the manufacturer.
Refrigerant is critical for air conditioning. It changes from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If the refrigerant is low, your air conditioner will run poorly and may not generate sufficient cool air. It might also cause a frozen evaporator coil, which as we mentioned before, halts the cooling cycle completely. You’ll need assistance from an HVAC professional, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor part of your AC unit is known as a condenser. This is actually a giant heat sink that removes muggy air from your home. If the metal fins are laced with cobwebs, the condenser can’t run well. Rinse down the unit to clear built-up debris and cut back bushes to make sure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Worn Out
While you’re checking the condenser, confirm the huge fan on the top of the unit is going. If the fan motor has stopped working, the condensing unit can’t break up heat properly, and your air conditioner might start blowing muggy air into your home.
Pay attention to the sound of the compressor running inside the condensing unit also. This is what drives your air conditioner, as the component lowers the temperature of the refrigerant. Then, the refrigerant can capture more heat when it comes back into your home. If the compressor stops working, you’ll typically need to purchase a new unit and set air conditioning installation.
