When the mercury begins to rise outdoors, you depend on your air conditioner to keep your residence cool. Your AC could be on, but the air blowing from your vents appears warm.
Here are the most standard reasons why this takes place and what actions you can take about it. If you need air conditioning repair in Knoxville, the Experts at R & M Climate Control Service Experts can support you. Like always, all our AC repair work is upheld by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Examine the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t running. Nothing’s wrong with this, but your utility costs will increase if the fan is on frequently. Switch the setting to “auto,” and the blower will only run when the compressor is running. This also means the air coming from the vents will consistently feel cold.
2.Filter is Dirty
The HVAC air filter captures airborne particles that can damage your heating and cooling units. If it ends up being too blocked, it can restrict airflow. This limits how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, stopping the cooling cycle from occurring. To avoid this, change the filter monthly or as recommended by the manufacturer.
3.Insufficient Refrigerant
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 the refrigerant is low, your air conditioner will operate poorly and may not create adequate cold air. It can also cause a frozen evaporator coil, which as previously mentioned, halts the cooling cycle altogether. You’ll need aid from an HVAC tech, like one from R & M Climate Control Service Experts, to fix any refrigerant issues.
4.Condensing Unit is Dirty
The outdoor part of your AC equipment is referred to as a condenser. This is essentially a giant heat sink that transfers hot air from your residence. If the metal fins are laced with dirt, the condenser can’t work efficiently. Wash down the system to remove debris that builds up and trim back vegetation to ensure the condenser isn’t blocked.
5.Condenser Fan or Compressor has Gone Bad
While you’re examining the condenser, confirm the large fan on the top of the system is going. If the fan motor has gone bad, the condensing unit can’t dissipate heat properly, and your air conditioner could start blowing hot air into your residence.
Pay attention to the sound of the compressor operating 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 capture more warmth when it circulates back into your home. If the compressor fails, you’ll likely need to buy a new system and schedule air conditioning installation.
