When the temp begins to rise outside, you expect your air conditioner to keep your house comfortable. Your AC could be on, but the air coming from your vents seems lukewarm.

1.Your Thermostat is Set Incorrectly
Check 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 bills will go up if the fan is on all the time. Adjust the setting to “auto,” and the blower will only operate when the compressor is working. This also means the air coming from the vents will consistently appear cold.
2.Filter is Dirty
The HVAC air filter catches airborne particles that can damage your heating and cooling system. 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 cold, it freezes, preventing the cooling cycle from taking place. To stop this, change the filter each month or as advised 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 shifts between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will cool poorly and may not generate sufficient chilled air. It can also cause a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle completely. You’ll need assistance from an HVAC pro, like one from Service Experts Heating & Air Conditioning, to repair any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor part of your AC system is known as a condenser. This is essentially a large heat sink that transfers humid air from your house. If the metal fins are covered with yard debris, the condenser can’t work efficiently. Hose down the unit to remove built-up debris and cut back bushes to ensure the condenser isn’t blocked.
5.Condenser Fan or Compressor has Gone Out
While you’re inspecting the condenser, confirm the big fan at the top of the unit is running. If the fan motor has gone bad, the condensing unit can’t break up heat properly, and your air conditioner might start sending muggy air into your home.
Take time to hear the compressor operating within 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 house. If the compressor fails, you’ll probably need to purchase a new air conditioner and book air conditioning installation.
