5 Reasons Why Your Air Conditioner May Not Feel Cool
When the mercury begins to rise outside your home, you expect your air conditioner to keep your residence cozy. Your AC may be operating, but the air blowing from your vents feels lukewarm.
Here are the most standard reasons why this happens and what you can do to fix it. If you have to have air conditioning repair in the U.S., the Experts at Service Experts Heating, Air Conditioning & Plumbing can help. Like always, all our AC repair service 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 blow even when the AC compressor isn’t going. Nothing’s wrong with this, but your utility expenses will be bigger if the fan runs all the time. Switch the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air coming from the vents will repeatedly appear cool.
2.Filter is Dirty
The HVAC air filter traps airborne particles that can wear out your heating and cooling units. If it becomes too clogged, it can lower airflow. This limits how much warm air flows over the indoor evaporator coil. If the refrigerant moving through the coil becomes too cold, it freezes, blocking the cooling cycle from taking place. To avoid this, replace the filter monthly or as recommended by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is essential for 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 run inefficiently and may not create enough chilled air. It may also create a frozen evaporator coil, which as we mentioned before, stops the cooling cycle fully. You’ll need help from an HVAC pro, like one from Service Experts Heating, Air Conditioning & Plumbing, to fix any refrigerant issues.
4.Condensing Unit Need to be Cleaned
The outdoor part of your AC unit is referred to as a condenser. This is essentially a large heat sink that exhausts muggy air from your house. If the metal fins are covered with yard debris, the condenser can’t do its job. Hose down the equipment to remove accumulated debris and trim back bushes to ensure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Out
While you’re examining the condenser, ensure the huge fan at the top of the equipment is running. If the fan motor has gone bad, the condensing unit can’t break up heat appropriately, and your air conditioner can start blowing warm air into your house.
Pay attention to the sound of the compressor operating within the condensing unit as well. This is the heart of your air conditioner, as the component lowers the temperature of the refrigerant. Then, the refrigerant can trap more warmth when it comes back into your residence. If the compressor goes out, you’ll typically need to purchase a new system and schedule air conditioning installation.
