Heat pump maintenance is a job for a qualified HVAC technician. Beyond regular air filter changes, there’s not much else about heat pump maintenance that’s DIY-friendly. When upkeep is performed according to manufacturer’s recommendations, heat pumps are capable of providing up to 4 units of heat or cooling for each one unit of electricity consumed. However, this superior efficiency and performance can be reduced by as much as 25 percent simply by neglecting proper maintenance.
Because heat pumps handle both the heating and cooling functions in most households, seasonal downtime is minimal, and wear and tear is year-round. Maintenance should be scheduled as close as possible to the outset of both the heating and cooling seasons.
Professional Heat Pump Maintenance
Here’s how a professional will ensure the long life and low operating costs of your heat pump:
- Inspect the indoor and outdoor coils for dust and debris and clean as required.
- Clear away any encroaching vegetation at the outdoor unit to create two feet of space for air circulation on all sides.
- Visually inspect the ductwork for evidence of leakage. If noted, pressure test and seal the ductwork.
- Measure airflow at supply vents in individual rooms.
- Check the system refrigerant level. If it’s low, perform leak detection procedure and repair leak.
- Inspect all the wiring and connectors. Tighten all connections and apply coating to weatherproof.
- Lubricate the blower motors indoors and out, as well as drive belt pulleys. Check drive belts for proper tension and excess wear.
- Make sure electronic controls operate properly and lock out heating function when cooling is activated at the thermostat and vice versa.
- Verify the thermostat reading with a mercury thermometer and calibrate the thermostat where necessary.
- Start the system and verify optimum air temperatures in supply vents of individual rooms.
