The amazing thing about a geothermal system in Edmonds is that the maintenance that it requires is very minimal. Geothermal systems have less moving parts than most other heating systems – and the majority of the mechanism is contained underground or inside, so these essential portions of the machine are not exposed to the elements. The tubbing, which is where the system gets its heat, is made to last for 25-50 years, and the heat pump portion above ground are very easy to access if you ever need to service them.
Nonetheless, maintaining a geothermal system working at peak efficiency is very important. If the geothermal system loses some of its efficiency, it will cost home and building owners money in energy costs, which makes little sense since geothermal system installation costs are higher than most other heating systems.
Its key component is the ground loop system, polyethelene tubing which carries refrigerant from below the Earth’s surface and back to an above-ground compressor. When installed correctly, the buried ground loop can last for decades. A leak in the metal tubing is usually the only problem if the ground loop is not installed correctly. In the case of a leak, it may be necessary to dig up the tubing – often installed at least ten feet below the surface – and repair the leak.
Other geothermal system components include its air handling unit, compressor, and pump. These components require periodic system checks by qualified professional heating and cooling technicians. maintenance normally requires filter changes and component lubrication, to name the most common. In some cases, building owners can perform their own filter replacement and refill of lubricants. However, it is recommended that call G & S Heating, Cooling, & Electric to perform a multiple-point inspection of the geothermal system components, usually during regularly scheduled annual or bi-annual service calls.
