Although HVAC systems are well-known for their reliability, they have limitations. If your HVAC system experiences a problem, it is usually a stressful situation that must be resolved immediately.
It is highly recommended that you have a basic understanding of common problems and solutions in order to ensure your system runs smoothly at all times. Some problems are easy to fix on your own, while others will require the assistance of a professional HVAC contractor.
Common HVAC Problems
Condenser Fan Motor
The contactor is part of the condenser fan motor. It works when there is a cooling need in order to create an electric connection. This will activate the motor. The compressor and the blower motor can both have contactors. Deterioration in the fan motor of the condenser compressor is the most common problem. The contactor may also become pitted, making it difficult for electricity to flow. This can prevent the condenser fan motor from starting correctly. The capacitor is another component of the motor that could cause problems with the HVAC system. The capacitor gives the compressor a slight boost in torque.
If your HVAC system is not cooling the room, contact an HVAC contractor to inspect the fan motor. He can also replace the contactor if necessary. If the capacitor is damaged, a North Myrtle Beach HVAC contractor can replace it.
Motor for the Evaporator Blower
You should also check the HVAC unit’s Evaporator Blower Motor. It has capacitors and a contactor. Blowing the fuse is one of the most common problems. The fuse protects the motor from excessive heat when the heating system is running. If your HVAC system isn’t working properly, the fuse may have flipped on and needs to be replaced. If you are unsure how to replace the breaker, it is strongly recommended to hire an HVAC contractor.
The condenser coil is located outside. They get dirty easily and should be replaced at least once per year. An HVAC contractor should clean the HVAC system if the grime or dirt gets worse. You should clean the HVAC unit and trim or completely remove any tall plants near the condenser. They can block airflow.
Thermostatic expansion valve
The thermostatic expansion valve is designed to inform the HVAC unit when and what it should do. Sometimes the thermostat may be turned off incorrectly or accidentally. Before you call for help, make sure the thermostat is on. If the thermostat doesn’t light up, it could be the thermostatic expansion valve. It could be that the thermostatic expansion valve isn’t working properly, or that the batteries need to be replaced. Before you hire a local HVAC contractor, make sure the thermostat is on and all settings are correct. Do not hesitate to call a professional if the problem seems complicated.
The compressor is the heartbeat of an HVAC system. The compressor will stop working if it is not properly charged with refrigerant liquid. Overcharging the unit with liquid refrigerant can cause liquid slugging. You should consult a North Myrtle Beach HVAC contractor if you are unsure about the right amount of refrigerant. The compressor will function at its best when it has the correct amount of liquid refrigerant.
