When the temperature starts rising outside, you rely on your air conditioner to keep your home cool. Your AC might be operating, but the air coming from your vents seems lukewarm.
Here are the most standard reasons why this occurs and what you need to do about it. If you require air conditioning repair in Hillsborough, the Experts at Fras-Air/General Service Experts can support you. Like always, all our AC repair service is upheld by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Look at the fan setting. If it is switched to “on,” the fan will run even when the AC compressor isn’t going. This is okay, but your cooling costs will be more expensive if the fan runs constantly. Adjust the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air radiating from the vents will repeatedly feel cold.
2.Filter is Clogged
The HVAC air filter traps airborne particles that can damage your heating and cooling units. If it gets too obstructed, it can reduce airflow. This limits how much warm air goes over the indoor evaporator coil. If the refrigerant moving through the coil becomes too chilled, it freezes, preventing the cooling cycle from occurring. To avoid this, replace the filter monthly or as suggested by the manufacturer.
3.Not Enough Refrigerant
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 badly and may not create sufficient chilled air. It may also cause a frozen evaporator coil, which as we mentioned before, stops the cooling cycle fully. You’ll need help from an HVAC tech, like one from Fras-Air/General Service Experts, to fix any refrigerant problems.
4.Condensing Unit Need to be Cleaned
The outdoor component of your AC unit is referred to as a condenser. This is basically a big heat sink that transfers warm air from your home. If the metal fins are clogged with cobwebs, the condenser can’t do its job. Hose down the unit to eliminate accumulated debris and shear back grass to make sure the condenser isn’t blocked.
5.Condenser Fan or Compressor has Gone Bad
While you’re examining the condenser, ensure the huge fan near the top of the equipment is spinning. If the fan motor has gone out, the condensing unit can’t break up heat properly, and your air conditioner could start sending warm air into your house.
Take time to hear the compressor working within the condensing unit also. This is what drives your air conditioner, as the part cools the refrigerant. Then, the refrigerant can capture more heat when it circulates back into your house. If the compressor fails, you’ll probably need to buy a new system and schedule air conditioning installation.
