1. Blown Fuses. Found in the evaporator coil, fuses protect the unit against overheating of the motors and or compressor. Once a motor starts going bad, a popped breaker is normally the first thing the technician will check.

2. Worn Contactor. There are three contactors in a unit: one for the compressor, one for the condenser fan motor, and one for the blower motor. When a call for cooling or heating is placed, the contactors engage, making an electrical connection starting the compressor and motors. Arcing and pitting will form on the contactor making it hard for the electrical current to pass and start the particular motor.

3. Capacitors. The run capacitor is used to help the motors of the unit run at a consistent speed, rated in microfarads. Start capacitors give the compressor a brief increase in starting torque. If either capacitor burns out, it will need to be replaced for your HVAC to work properly.

4. Gas valve. The gas valve meters the gas to flow from your gas line to your unit. They are only used during the heating season. If the gas valve gets corroded, it will need to be replaced.

5. Filters. Filters will always get dirty and clogged from air particles. Once this happens, the filter will need to be changed. One way to tell if the filter needs to be changed is to hold it up to the light see if you can see light pass through it. If you cannot, the filter needs to be changed. If a dirty filter is left in, it will reduce the air flow to the unit causing the unit to freeze.

6. Thermostat. This is the device that controls the system, telling it what to do and when to do it. Before calling an HVAC company, make sure the thermostat is on. Many times the thermostat is accidentally turned off.

7. Drain lines. The drain line commonly becomes clogged with dirt or algae. With the unit clogged, the drain pan will fill up and cause water to leak over and create some water damage to the ceiling tiles or ceiling.

8. Refrigerant leak. Refrigerant leaks normally happen due to vibration of the unit when it is operating. The only refrigerant leaks that cannot be repaired are the ones in the condenser or evaporator coils. If the leak is found in another place the technician will remove what is left and charge the unit levels back to their correct amount.

9. Compressor. This is the heart of the A/C unit. The compressor is always located with the condenser coil. If the unit is undercharged the compressor it will run hot and will eventually seize. If the unit is overcharged, your liquid refrigerant will get back to the compressor and cause liquid slugging. If is important that the A/C unit has the proper amount of refrigerant.

10. Condenser Coil. These are always located outside with the compressor. They are exposed to the outdoor elements, so they often get dirty and should be cleaned yearly. This can be done with a water hose when the unit is not operating. If the dirt and grime get bad enough a HVAC technician will have to clean the coil with chemical cleaner.

11. Evaporator Coil. On split systems the evaporator coil is located in the attic, but on a package unit it is located outside with rest of the unit. If the coil is located inside, cleaning will only be necessary if suggested and should only be about every three years or so. If the evaporator coil cracks, an HVAC professional will need to fix the break.
