When the mercury begins to rise outdoors, you rely on your air conditioner to keep your home cool. Your AC could be running, but the air coming from your vents appears lukewarm.
Here are the most standard reasons why this takes place and what you need to do to repair it. If you need air conditioning repair in Birmingham, the Experts at Norrell Service Experts can help. Like always, all our AC repair labor is supported 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 blow even when the AC compressor isn’t working. Nothing’s wrong with this, but your electricity costs will go up if the fan operates constantly. Change the setting to “auto,” and the blower will only operate when the compressor is working. This also means the air radiating from the vents will always appear cold.
2.Filter Need to be Changed
The HVAC air filter traps airborne particles that can damage your heating and cooling system. If it gets too blocked, it can lower airflow. This reduces how much warm air flows over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, blocking the cooling cycle from occurring. To avoid this, replace the filter every month or as suggested by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is the key to 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 cool inefficiently and may not produce sufficient chilled air. It can also lead to a frozen evaporator coil, which as we already mentioned, prevents the cooling cycle fully. You’ll need help from an HVAC tech, like one from Norrell Service Experts, to fix any refrigerant leaks.
4.Condensing Unit Need to be Cleaned
The outdoor component of your AC system is known as a condenser. This is essentially a giant heat sink that transfers muggy air from your house. If the metal fins are covered with dirt, the condenser can’t work efficiently. Hose down the equipment to remove accumulated debris and cut back grass to make sure the condenser can “breathe.”
5.Condenser Fan or Compressor has Worn Out
While you’re inspecting the condenser, ensure the big fan near the top of the system is spinning. If the fan motor has gone bad, the condensing unit can’t exhaust heat like it should, and your air conditioner may start sending muggy air into your residence.
Pay attention to the sound of the compressor operating in the condensing unit as well. 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 capture more humidity when it comes back into your residence. If the compressor goes out, you’ll likely need to buy a new air conditioner and schedule air conditioning installation.
