When the temperature begins to rise outdoors, you rely on your air conditioner to keep your residence cool. Your AC might be operating, but the air coming from your vents appears lukewarm.
Here are the most common reasons why this occurs and what you can do about it. If you need air conditioning repair in North America, 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
Examine the fan setting. If it is switched to “on,” the fan will run 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. Switch the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air issuing from the vents will consistently seem cool.
2.Filter is Dirty
The HVAC air filter traps airborne particles that can wear out your heating and cooling system. If it gets too blocked, it can reduce airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cool, it freezes, blocking the cooling cycle from taking place. To stop this, change the filter each month or as recommended by the manufacturer.
3.Refrigerant is Low
Refrigerant is the key to air conditioning. It shifts from a low-pressure gas to a high-pressure liquid as it shifts between the indoor evaporator coil and outdoor condensing unit. If the refrigerant is low, your air conditioner will cool poorly and may not produce enough cold air. It can also result in a frozen evaporator coil, which as previously mentioned, prevents the cooling cycle altogether. You’ll need assistance from an HVAC professional, like one from Service Experts Heating & Air Conditioning, to fix any refrigerant leaks.
4.Condensing Unit Need to be Cleaned
The outdoor part of your AC equipment is known as a condenser. This is actually a large heat sink that transfers humid air from your house. If the metal fins are clogged with cobwebs, the condenser can’t run well. Wash down the equipment to eliminate built-up debris and cut back bushes to make sure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Bad
While you’re examining the condenser, make sure the huge fan on the top of the equipment is spinning. If the fan motor has gone bad, the condensing unit can’t break up heat properly, and your air conditioner could start sending warm air into your residence.
Listen for the sound of the compressor working in the condensing unit also. This is the heart of your air conditioner, as the component cools the refrigerant. Then, the refrigerant can trap more warmth when it moves back into your house. If the compressor goes out, you’ll probably need to purchase a new system and schedule air conditioning installation.
