People who have a geothermal heat pump or are interested in having one installed are often curious about these systems’ requirements for maintenance. On the one hand, it seems as if geothermal heat pumps would need a great deal of maintenance because of the extent of their layout, which consists of a set of underground coils to carry out heat exchange. On the other hand, geothermal heat pumps are known for their durability and longevity, and the buried coils would seem to be removed from where they could sustain damage.
The truth is neither good nor bad: geothermal heat pumps require the same amount of maintenance as air-source heat pumps. They have longer lifespans, but the type of work that goes into maintenance and the frequency with which it should be done (annually) is similar. Maintenance for both is mandatory; you can’t expect energy efficiency or a long service life without regular inspections and tune-ups
Advantage Airtech specialises in installation, repair, and geothermal system maintenance in Toronto, ON. Call us today to start regular maintenance visits for your heat pump.
Some of the needs geothermal systems have for maintenance
For the most part, a geothermal heat pump has the same set of maintenance steps as a standard air-source heat pump. The maintenance techs will check on the air filter and change it. They will look over the thermostat to make sure that it is calibrated. They look over the reversing valve to see that it can correctly switch the heat pump from one mode to the other. They will take care to investigate the condensate pans and drains to check that water is draining properly from the system. Motors parts are inspected and cleaned where necessary. The indoor coil also receives cleaning if needed.
Of course, geothermal systems have a few specific concerns that the technicians will keep in mind. If the technicians suspect that there is water leaking from the ground loops, they’ll insert a colored dye into the system and then check above ground to see if the dye has seeped up from any holes in the loops. If the geothermal heat pump uses an open loop system, its coax heat exchanger will need to be cleaned to eliminate deposits from hard water; a chemical flush will keep away build-up.
If you schedule regular geothermal system maintenance in Toronto, ON, you should expect at least 25 years of life from the internal heat pump components and more than 50 from the ground loops. That’s a fantastic service lifespan for a system, especially one that is as energy-efficient as a geothermal heat pump.
