A Heat Pump Tuneup Equals Peak Performance

Your heat pump has probably proved its value over the past several seasons. However, even the most reliable heat pump needs preventive maintenance to keep it working at its best. A heat pump tuneup improves system performance, extends the useful life of the equipment, and reduces the possibility of malfunctions and breakdowns that could be expensive to fix.

When to Schedule Heat Pump Maintenance

Preventive maintenance should be performed on your heat pump at least once a year. Since heat pumps work constantly throughout both summer and winter, a better schedule might be twice-yearly maintenance, one in the spring and another in the fall.

Tune-Up Checklist

Your HVAC technician will conduct a series of tests, adjustments and replacements to improve system performance, such as:

  • Check refrigerant lines and add refrigerant, if needed: The heat pump requires a manufacturer-specified amount of refrigerant to function properly, so if the system contains too little refrigerant, your technician should add some. He should also check refrigerant lines for leaks and fix any that are found.
  • Verify and calibrate system controls: The heat pump should be checked for proper control operation, and any bad controls should be repaired or replaced. Thermostats should be calibrated to ensure proper indoor temperature readings. Any moving parts, such as fans, should be lubricated.
  • Clean and tighten electrical connections: Consistent vibration could loosen electrical connections within the system. All connections should be tightened and cleaned.
  • Check ductwork: The system’s ductwork should be checked to ensure all connections between duct sections are tight and well sealed.
  • Clean the indoor and outdoor coils and change air filters: Air filters should be changed to ensure proper airflow. The system’s outdoor condenser/compressor should be cleaned to ensure nothing is obstructing airflow inside or out. If you want to give the technician more time to work on technical issues, you could take care of these simple tasks yourself.
