When the temperature starts rising outside your home, you rely on your air conditioner to keep your house cozy. Your AC could be on, but the air coming from your vents appears warm.
Here are the most common reasons why this happens and what you need to do about it. If you have to have air conditioning repair in Rochester, the Experts at Strogen's Service Experts can help. Like always, all our AC repair work is backed by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Look at the fan setting. If it says “on,” the fan will blow even when the AC compressor isn’t going. This isn’t a problem, but your energy expenses will be more expensive if the fan operates frequently. 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 appear chilly.
2.Filter is Dirty
The HVAC air filter captures airborne particles that can damage your heating and cooling equipment. If it becomes too blocked, it can reduce airflow. This restricts how much warm air flows over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cool, it freezes, blocking the cooling cycle from happening. To stop this, put in a new filter monthly or as recommended by the manufacturer.
3.Refrigerant is Low
Refrigerant is the key to air conditioning. It changes from a low-pressure gas to a high-pressure liquid as it shifts between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will operate inefficiently and may not create adequate chilled air. It could also lead to a frozen evaporator coil, which as we already mentioned, stops the cooling cycle completely. You’ll need help from an HVAC pro, like one from Strogen's Service Experts, to solve any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor piece of your AC unit is referred to as a condenser. This is basically a giant heat sink that transfers muggy air from your residence. If the metal fins are laced with yard debris, the condenser can’t run well. Wash down the equipment to clear debris that builds up and cut back vegetation to make sure the condenser isn’t blocked.
5.Condenser Fan or Compressor has Worn Out
While you’re examining the condenser, verify the large fan near the top of the unit is running. If the fan motor has gone bad, the condensing unit can’t exhaust heat like it should, and your air conditioner could start blowing hot air into your house.
Listen for the sound of the compressor operating in the condensing unit also. This is what drives your air conditioner, as the part cools the refrigerant. Then, the refrigerant can collect more warmth when it moves back into your home. If the compressor goes out, you’ll typically need to purchase a new system and book air conditioning installation.
