5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury starts rising outside your home, you depend on your air conditioner to keep your home comfortable. Your AC may be operating, but the air blowing from your vents appears lukewarm.

Here are the most frequent reasons why this takes place and what you need to do about it. If you need air conditioning repair in Livermore, the Experts at Service Experts Heating & Air Conditioning can support you. Like always, all our AC repair labor is supported by a 100% Satisfaction Guarantee.*

1.Your Thermostat is Set Improperly

Look at the fan setting. If it says “on,” the fan will operate even when the AC compressor isn’t running. Nothing’s wrong with this, but your electricity bills will be bigger if the fan is on constantly. Adjust the setting to “auto,” and the blower will only work when the compressor is working. This also means the air coming from the vents will consistently appear cool.

2.Filter is Dirty

The HVAC air filter traps airborne particles that can damage your heating and cooling system. If it ends up being too obstructed, it can lower airflow. This reduces how much warm air flows over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, preventing the cooling cycle from occurring. To prevent this, put in a new filter each month or as recommended by the manufacturer.

3.Not Enough Refrigerant

Refrigerant is the key to air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it moves 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 adequate cold air. It may also cause a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle altogether. You’ll need help from an HVAC pro, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant issues.

4.Condensing Unit Need to be Cleaned

The outdoor component of your AC system is referred to as a condenser. This is basically a giant heat sink that exhausts humid air from your house. If the metal fins are covered with yard debris, the condenser can’t run well. Hose down the unit to eliminate built-up debris 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, verify the large fan at the top of the equipment is working. If the fan motor has gone bad, the condensing unit can’t dissipate heat appropriately, and your air conditioner might start sending muggy air into your house.

Take time to hear the compressor running inside the condensing unit as well. This is one of the most important parts of your air conditioner, as the part cools the refrigerant. Then, the refrigerant can collect more warmth when it moves back into your residence. If the compressor stops working, you’ll likely need to get a new unit and schedule air conditioning installation.
