Common Problems with Air Conditioning Units:

1. Refrigerant Leaks

If your air conditioner is low on refrigerant, either it was undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. A trained technician should fix any leak, test the repair, and then charge the system with the correct amount of refrigerant. Remember that the performance and efficiency of your air conditioner are greatest when the refrigerant charge exactly matches the manufacturer’s specification and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment.

2. Inadequate Maintenance

If you allow filters and air conditioning coils to become dirty, the air conditioner will not work properly, and the compressor or fans are likely to fail prematurely.

3. Electric Control Failure

The compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently, as is common when a system is oversized. Because corrosion of wire and terminals is also a problem in many systems, electrical connections and contacts should be checked during a professional service call.

4. Sensor Problems

Room air conditioners feature a thermostat sensor, located behind the control panel, which measures the temperature of air coming into the evaporative coil. If the sensor is knocked out of position, the air conditioner could cycle constantly or behave erratically. The sensor should be near the coil but not touching it; adjust its position by carefully bending the wire that holds it in place.

5. Drainage Problems

When it’s humid outside, check the condensate drain to make sure it isn’t clogged and is draining properly. Room air conditioners may not drain properly if not mounted level.



Our Air Conditioning Technicians Will:

  1. Check for the correct amount of refrigerant
  2. Test for refrigerant leaks using a leak detector
  3. Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it into the atmosphere
  4. Check for and seal duct leakage in central systems
  5. Measure airflow through the evaporator coil
  6. Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously
  7. Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary
  8. Oil motors and check belts for tightness and wear
  9. Check the accuracy of the thermostat.

GH&AC installed my furnace three years ago. I am very happy with the installation and the furnace. I recently ran out of heating oil 🤦🏻‍♂️. After refilling the tank, the furnace would not produce heat. GH&AC sent Woody over to have a look. He did a great job of fixing my furnace and charged me a very reasonable fee. If you’re looking for old-fashioned service, look no further.
