5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp starts rising outdoors, you rely on your air conditioner to keep your house cozy. Your AC may be on, but the air issuing from your vents feels too hot. 

Here are the most frequent reasons why this happens and what actions you can take to repair it. If you have to have air conditioning repair in Voorhees, the Experts at Atmostemp Service Experts can assist you. Like always, all our AC repair work is supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Look at the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t going. This is okay, but your electricity expenses will increase if the fan is on all the time. Adjust the setting to “auto,” and the blower will only operate when the compressor is on. This also means the air issuing from the vents will consistently appear cool. 

2.Filter is Dirty

The HVAC air filter catches airborne particles that can damage your heating and cooling system. If it becomes too obstructed, it can reduce airflow. This reduces how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too chilled, it freezes, blocking the cooling cycle from happening. To avoid this, put in a new filter each month or as recommended by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is critical for 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 there isn’t enough refrigerant, your air conditioner will operate poorly and may not produce sufficient chilled air. It may also result in a frozen evaporator coil, which as we already mentioned, stops the cooling cycle completely. You’ll need assistance from an HVAC tech, like one from Atmostemp Service Experts, to solve any refrigerant leaks. 

4.Condensing Unit is Blocked

The outdoor piece of your AC unit is known as a condenser. This is essentially a large heat sink that removes muggy air from your house. If the metal fins are laced with cobwebs, the condenser can’t work efficiently. Rinse down the unit to remove debris that accumulates and cut back grass to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Gone Out

While you’re inspecting the condenser, ensure the large fan at the top of the unit is going. If the fan motor has gone bad, the condensing unit can’t break up heat appropriately, and your air conditioner could start sending muggy air into your house. 

Pay attention to the sound of the compressor running within the condensing unit too. This is what drives your air conditioner, as the piece lowers the temperature of the refrigerant. Then, the refrigerant can capture more warmth when it moves back into your house. If the compressor goes out, you’ll likely need to get a new system and schedule air conditioning installation.
