When the mercury begins to rise outside your home, you expect your air conditioner to keep your residence comfortable. Your AC may be operating, but the air blowing from your vents appears lukewarm.
Here are the most standard reasons why this happens and what you can do to fix 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 supported by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Wrong
Check the fan setting. If it is switched to “on,” the fan will operate even when the AC compressor isn’t running. This isn’t a problem, but your utility expenses will go up if the fan runs constantly. Change the setting to “auto,” and the blower will only work when the compressor is working. This also means the air issuing from the vents will consistently appear cold.
2.Filter is Clogged
The HVAC air filter captures airborne particles that can ruin your heating and cooling units. If it becomes too blocked, it can restrict airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant moving through the coil becomes too cold, it freezes, stopping the cooling cycle from taking place. To avoid this, put in a new filter every month or as advised by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is critical for air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will run badly and may not produce adequate chilled air. It may also cause 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 solve any refrigerant issues.
4.Condensing Unit is Dirty
The outdoor piece of your AC system is called a condenser. This is basically a large heat sink that removes 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 clear accumulated debris and trim back grass to make sure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Out
While you’re checking the condenser, confirm the big fan at the top of the equipment is running. If the fan motor has stopped working, the condensing unit can’t exhaust heat properly, and your air conditioner may start blowing muggy air into your home.
Listen for the sound of the compressor operating in the condensing unit also. This is what drives your air conditioner, as the piece lowers 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 likely need to purchase a new air conditioner and book air conditioning installation.
