5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature begins to rise 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 Rochester, the Experts at Strogen's 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, replace the filter each month or as suggested by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is critical for 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 run poorly and may not generate adequate chilled air. It may also result in a frozen evaporator coil, which as previously mentioned, halts the cooling cycle altogether. You’ll need assistance from an HVAC tech, like one from Strogen's Service Experts, to repair any refrigerant issues. 

4.Condensing Unit Need to be Cleaned

The outdoor part of your AC system is known as a condenser. This is actually a big 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 system to clear debris that accumulates and cut back grass to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Gone Bad

While you’re checking the condenser, ensure the big fan at the top of the system is going. If the fan motor has gone out, the condensing unit can’t exhaust heat appropriately, and your air conditioner could start sending hot 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 part lowers the temperature of the refrigerant. Then, the refrigerant can capture more warmth when it circulates back into your house. If the compressor fails, you’ll typically need to get a new system and book air conditioning installation.
