HVAC systems are known for their reliability but they also have their own limitations. When your HVAC system encounters a problem, it’s usually a stressful encounter that needs to be addressed immediately.
Having a basic knowledge of the common problems and their solutions to make sure that your system is fully functional at all times is highly recommended. A few of the problems can be easy to handle on your own while others require hiring a professional HVAC contractor.
Condenser Fan Motor
The condenser fan motor contains the contactor which works whenever there’s a need for cooling in order to develop an electric connection. This will trigger the motor. Contactors can be located in the compressor as well as the blower motor. The most common problem with contactors is deterioration in the condenser fan motor. Pitting may also develop on the contactor, which will make it hard for electrical current to pass. This will prevent the condenser fan motor from starting properly. Another part of this motor that might burn out or prevent the HVAC system from functioning properly is the capacitor. It provides the compressor with a minor boost in starting torque.
Get in touch with an HVAC contractor who can inspect the condenser fan motor just in case your system does not cool the room so he can take a look at the contactor and have it replaced if needed. The North Myrtle Beach HVAC contractor will also change the capacitor in case it is burnt out.
Evaporator Blower Motor
The HVAC unit’s evaporator blower motor, which features capacitors and a contactor, should also be checked. One common problem with it is a blown fuse. The primary function of the fuse is to protect the motor from overheating whenever the system is heating your home. In case your HVAC system is not functioning properly, the breaker may have flipped off and has to be changed. It is highly recommended that you hire an HVAC contractor to do the replacement if you don’t know how to do it yourself.
Condenser Coil
The condenser coil is located outside along with the compressor and that means they usually get dirty and have to be changed at least once a year. If the grime and the dirt become worse, the HVAC system needs to be cleaned by an HVAC contractor. Apart from having the unit cleaned, you should also trim back or totally get rid of tall plants that are located close to the condenser because they may block the airflow.
Thermostatic Expansion Valve
The function of the thermostatic expansion valve is to tell the HVAC unit what it needs to do and when it should be done. In a few cases, the thermostat is turned off accidentally or perhaps set incorrectly, so before you contact any help, be perfectly sure that the thermostat is turned on. In case the thermostat isn’t lit up, the problem might be with the thermostatic expansion valve. Perhaps it is not functioning properly or the batteries have to be changed. You need to be sure that the thermostat is turned on and the settings are set correctly before you conclude that the thermostatic expansion valve has an issue and hire an HVAC contractor. If the problem looks complicated, don’t hesitate to hire a professional.
Compressor
The main part of the heart of the HVAC system is the compressor. If the unit is undercharged with a refrigerant liquid, the compressor will run hot and stop working. If it is overcharged, the liquid refrigerant will return to the compressor and cause liquid slugging. If you don’t know anything about the correct refrigerant, you have to consult an HVAC contractor who can recommend the correct amount. It is important for the system to have the right liquid refrigerant amount to ensure that the compressor functions at its best.
