When the temp begins to rise outside your home, you expect your air conditioner to keep your house comfortable. Your AC could be on, but the air blowing from your vents seems too hot.
Here are the most frequent reasons why this happens and what you can do to repair it. If you need air conditioning repair in Roanoke, the Experts at Service Experts Heating & Air Conditioning can support you. Like always, all our AC repair service is upheld by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Check the fan setting. If it is switched to “on,” the fan will run even when the AC compressor isn’t running. This is okay, but your energy expenses will be bigger if the fan runs constantly. Change the setting to “auto,” and the blower will only work when the compressor is running. This also means the air radiating from the vents will repeatedly seem chilly.
2.Filter is Dirty
The HVAC air filter catches airborne particles that can wear out your heating and cooling system. If it becomes too blocked, it can restrict airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, blocking the cooling cycle from taking place. To avoid this, replace the filter every month or as suggested by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is essential for air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will run badly and may not produce adequate cool air. It may also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle altogether. You’ll need assistance from an HVAC pro, like one from Service Experts Heating & Air Conditioning, to repair any refrigerant problems.
4.Condensing Unit is Blocked
The outdoor piece of your AC system is called a condenser. This is basically a large heat sink that transfers warm air from your home. If the metal fins are laced with cobwebs, the condenser can’t do its job. Hose down the unit to eliminate accumulated debris and trim back grass to confirm the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Out
While you’re inspecting the condenser, make sure the huge fan at the top of the equipment is running. If the fan motor has stopped working, the condensing unit can’t break up heat properly, and your air conditioner can start blowing muggy air into your home.
Listen for the sound of the compressor working in the condensing unit also. This is one of the most important parts of your air conditioner, as the piece reduces the temperature of the refrigerant. Then, the refrigerant can collect more heat when it moves back into your home. If the compressor stops working, you’ll typically need to get a new air conditioner and set air conditioning installation.
