Servicing

Has your hydro bill increased recently? One of the best ways to check if your system is running efficiently is to look over your hydro bill. If your usage has increased, it could be an indication that your geothermal unit has an issue and may need servicing.

We recommend setting an annual inspection and maintenance for your geothermal system and  loop system. Especially important is freeze protection. All ground / ocean and water loops must be protected from freezing to be able to work effectively during the colder months.

Maintenance for Your Geothermal System

One of the biggest issues we find today with geothermal systems is that they are not well maintained. This will cause your energy bills to increase, since a unit under pressure will cost more to run annually. In order to keep your equipment running as efficiently and safely as possible, it is recommended by the manufacturer to have your geothermal unit and the water or ground loop serving it maintained once a year.

Our geothermal maintenance checklist includes:

  • check source temperature in
  • check source temperature out
  • record source delta T
  • check load temperature in
  • check load temperature out
  • record load delta T
  • check compressor amps
  • check compressor bearings
  • check contactor
  • check capacitor(s)
  • check blower amps
  • check blower bearings
  • check return air temperature
  • check supply air temperature
  • check pressure drop/rise across the coil
  • check operation of all circulation pumps
  • check operation of thermostat
  • check condition of air filter (change out if necessary)
  • check all wiring for tightness and wear
  • inspect pipe insulation
  • check to make sure nothing is rubbing (ie copper on copper)
  • check controls and set points
  • check operation of reversing valve
  • check system refrigeration pressures (only if there is an issue)
  • check and record heat of extraction
  • check source temperature in
  • check source temperature out
  • record source delta T
  • check load temperature in
  • check load temperature out
  • record load delta T
  • check compressor amps
  • check compressor bearings
