When the temp starts to rise outside your home, you rely on your air conditioner to keep your home comfortable. Your AC could be running, but the air coming from your vents appears too hot.
Here are the most standard reasons why this happens and what you need to do about it. If you require air conditioning repair in Raleigh, the Experts at Service Experts Heating & Air Conditioning can help. Like always, all our AC repair work is backed by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Incorrectly
Look at the fan setting. If it is switched to “on,” the fan will run even when the AC compressor isn’t running. Nothing’s wrong with this, but your cooling bills will increase if the fan is on frequently. Change the setting to “auto,” and the blower will only operate when the compressor is on. This also means the air radiating from the vents will consistently appear chilly.
2.Filter Need to be Changed
The HVAC air filter captures airborne particles that can damage your heating and cooling units. If it gets too obstructed, it can restrict airflow. This restricts how much warm air moves over the indoor evaporator coil. If the refrigerant passing through the coil becomes too chilled, it freezes, preventing the cooling cycle from taking place. To stop this, put in a new filter monthly or as recommended by the manufacturer.
3.Not Enough Refrigerant
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 operate poorly and may not produce sufficient cool air. It could also create a frozen evaporator coil, which as previously mentioned, stops the cooling cycle altogether. You’ll need help from an HVAC tech, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant problems.
4.Condensing Unit is Dirty
The outdoor part of your AC unit is called a condenser. This is essentially a large heat sink that removes warm air from your home. If the metal fins are laced with cobwebs, the condenser can’t run well. Rinse down the system to clear built-up debris and shear back grass to ensure the condenser isn’t blocked.
5.Condenser Fan or Compressor has Worn Out
While you’re checking the condenser, confirm the huge fan near the top of the system is working. If the fan motor has gone out, the condensing unit can’t break up heat appropriately, and your air conditioner may start circulating hot air into your residence.
Pay attention to the sound of the compressor running inside the condensing unit also. This is one of the most important parts of your air conditioner, as the part reduces the temperature of the refrigerant. Then, the refrigerant can capture more heat when it comes back into your house. If the compressor stops working, you’ll probably need to purchase a new unit and schedule air conditioning installation.
