Heat pumps provide homeowners with an efficient way to both heat and cool their homes. They use advanced technology to draw heat from the home when it is hot outside, or into the home when it is cold.
Like all modern appliances, they require periodic maintenance. Unlike some appliances, though, most of the maintenance that heat pumps require will take the expertise of a professional plumber or repair technician.

Both the indoor and outdoor coils must be inspected for signs of wear. They must also be cleaned to remove any dust or debris. The outside unit should also be kept clear of any encroaching vegetation, as it requires at least two feet of space on all sides for proper air circulation.
All ducts within the home require periodic inspection to ensure that there are no leaks. Most of the time this can be accomplished through a basic visual inspection. However, in some cases, the inspection may require pressure tests and reseal if any evidence of leakage is present.
Wiring and Connectors
All wiring and connectors should be inspected for safety and signs of wear. Connections often must be tightened periodically, and outdoor wiring must be weatherproofed to ensure that it does not come into contact with moisture.
Belts, Pulleys, and Motors
The blower motors for both the indoor and outdoor units must be lubricated periodically, as must the drive belt pulleys. These drive belts should also be inspected for signs of excessive wear and replaced as needed.
Calibrating the Thermostat
A professional technician can verify thermostat readings in order to ensure their accuracy using a mercury thermometer. Should the readings be inaccurate, the thermostat will need to be recalibrated to reflect actual indoor temperatures.
Checking Air Flow
The air flow from all ducts will be checked to make sure there are no blockages in the system and all rooms are receiving adequate air flow. Optimum temperatures should also be verified for each individual supply vent during a routine Heat Pump Service in Bellingham WA. Visit to schedule a visit with a professional today.
