In 1902, Willis Carrier invented modern air conditioning. More than a century later, people still enjoy the comforts of HVAC. Despite immense technological progress, HVAC still occasionally has problems.

You can’t avoid HVAC repairs. Be prepared for when then the five most common HVAC problems arise by reading on.

1. Central AC Doesn’t Work

The central air conditioning not working is an all-too-common problem. Fortunately, there are some quick fixes.

Ensure the thermostat’s set to cool and its temperature setting is at least three degrees below the ambient room temperature. Also, make sure the power’s on.

You could try turning off the power to the air conditioner then removing the thermostat’s body. Separate the body from the base and replace the batteries.

A last-ditch solution is checking the compressor’s contactor and capacitor. It may be time to replace the capacitor.

2. AC Running But Not Cooling

Another of the most common HVAC issues is the air conditioner running but not cooling. Something could be limiting or blocking airflow. Look for dirty air filters that may be clogged by an accumulation of debris and dirt.

If that doesn’t fix it, verify that the thermostat’s working right. An electronic thermostat that doesn’t display any information may have dead batteries or be worn out.

An alternative cause of the problem is low refrigerant (freon). It’s often due to refrigerant leaks, in which case you should call one of the HVAC technicians in the Visalia or Hanford area.

3. Air Conditioner Doesn’t Turn Off

Your air conditioning should turn off when the room temperature reaches the temperature that the thermostat’s set at. If it doesn’t, then there’s a problem with the electrical system running the outside condensing unit or the thermostat itself.

You should probably replace your thermostat if it’s blank or if the AC turns off when you turn the heat on. You probably don’t need to replace your thermostat if it works with the furnace.

4. Air Handler Doesn’t Blow Air Right

Next, the air handler could fail to blow air properly. If that’s the case, the indoor evaporator coil may be frozen or dirty.

Reduced airflow can make the coil freeze and thus block airflow. A dirty coil, dirty filters, broken fan motor, or dirty squirrel cage blower can all decrease airflow.

Simply replace the belt that connects your air handler’s motor to the blower.

5. The AC Has a Water Leak

Air conditioners’ condensation is water that needs to exit the air handler. Use a drain tube or plastic pipe to get the water out.

A condensate pump connects to a half-inch rubber or vinyl tube that goes to a drain outdoors. A drain tube goes outside and ends near the compressor, condensate pump, or floor drain.
