Taking care of your geothermal cooling system in spring can indeed save you money in the long run by ensuring it operates efficiently.


Let’s begin by checking on and cleaning the Internal Condensate Drain Pan.

The drain pan collects condensation from the air coil. Water dripping into the pan is normal; however, the drain hole (or drain hose) may occasionally become clogged. This will most likely occur during the cooling season.

How do I unclog the drain pan?

In the cooling mode, moisture removed from the air forms as condensation on the air coil, and the resulting water runs down to the condensate drain pan. The drain can pick up lint and dirt, especially with dirty air filters. If overflow occurs, the DRAIN light will come on (in units equipped with status lights) and the system will shut down. If the water does not run freely, clean the drain pipe. Dilute a capful of chlorine bleach in a quart of water and pour the solution in the drain pan once a year. This helps prevent algae.

To gain access to the drain pan for inspection or cleaning:

• Turn off all power to unit and auxiliary heat, at the breaker box
• Remove the screws holding the fan compartment door closed.
• Lift the door up and pull out at the bottom.

Note: The drain pan is the black plastic or metal rectangular pan with the drain hole under the air coil.

It is recommended that you have your system thoroughly checked by us twice per year (usually Spring and Fall) to maintain optimum performance.

Regular checks will ensure that your system performs safely and efficiently with less likelihood of major problems and premature failure.


Our preventative maintenance inspection package (PMI’s) is all about making sure your system keeps running as smoothly as the day you got it. It allows our technicians to review your unit to confirm that your geothermal unit is still operating optimally. We check things such as refrigerant pressures, loop pressure, temperature, the heat of extraction & rejection, amp draw, the hot water pump, strip heater, air coil, condensate drain, & more.

Next, let’s make sure that your Filter maintenance schedule is in tip top shape.

New air filters enable effective air circulation throughout all rooms. Replacing the air filters also averts sudden mechanical malfunction.

Electric and Pleated disposable filters (every 4-6 months)
Washable Filters (Clean every 1-2 months)

If you use a disposable filter, change it regularly before it accumulates too much dirt. Never attempt to clean it.
Simply throw it away and install a new one. Do not turn a dirty filter over to the clean side and reinstall it—this results in blowing the accumulated dirt right back into the home.
