The core of an HVAC system, a compressor is important to the cooling and heating of a house. Propelling coolant inside an HVAC emits heat. However, if this heat gets too strong, the system may shut down.
Compressor Overload: What does it mean?
Thermal overload of an AC compressor is a very common cause of breakdown, and usually happens on the coldest or hottest days of the season, when the system has to work overtime. The overload is responsible for component failures 49% of the times. It is a serious and expensive problem if it progresses. Depending on the system’s age, it may result in you having to completely replace the system.
Compressor Burn Out: What causes it?
The main causes of compressor burnout is neglect by homeowners, careless maintenance and installation, including,
- Dirty condenser coils.
- A dirty air filter.
- Undercharged or overcharged refrigeration system.
- Refrigerant leaks.
- Acid burnout.
- Other heat sources situated near the condenser (hot water pipes, dryer vent).
- Improper airflow due to poor system location (covered by deck, weeds or bushes).
- Improper airflow due to debris (trash within external system components, grass clippings).
- Failure of other components (capacitor, fan motor, reversing valve, thermal expansion valve, refrigerant lines, etc.).
- Corroded wires and loose connections, or inadequate electricity supply into home, leading to high amperage / low voltage problems.
How do you prevent compressor overloads from damaging the whole system?
Never neglect homeowner maintenance.
It is important that you change the air filter after every three months. Also, make sure you clear debris around the external system, preserving 18-36 inches of clearance at all sides.
Hire a HVAC professional you can trust.
Extending the compressor’s life requires accurate installation performed by a knowledgeable professional, and routine professional maintenance that includes verification of refrigerant levels, connections, lubrication, coil cleaning, and maintenance of operation as per the manufacturer’s specifications to ensure system longevity.
Consider extra protection.
Adding a compressor overload protector can safeguard your HVAC system. Located nearby the condenser, this special sensor monitors temperatures, shutting down the compressor temporarily to prevent it from overheating. By turning your system off to let the compressor cool, can help prevent thermal overload of the AC compressor and give you an indication that your system needs repair before the problems become too costly. In case your compressor is overheating, it is important to understand why, as just replacing components may lead to the problem repeating itself again. In case your system is experiencing increased incidence of overheating, make sure you call for help immediately. The professionals will check your system and find out what is wrong. It is a good idea to hire a service that has good reviews.
