Available accessories

  • Programmable thermostat Keeps the home more comfortable by operating the unit on a set schedule and temperature range. This also saves on energy costs by setting the unit back while the home is unoccupied.
  • Non-programmable thermostat Designed to take maximum advantage of the multi-stage functionality of the unit. This allows the unit to achieve maximum savings by only operating at the right range to match the current weather.
  • Auxiliary internal electric heater Adds that little bit of extra heat on those few coldest days. Also helps to balance the system size by balancing out those few extreme days. With a standard stab-in design, you don't have to drop the blower to install.
  • Auxiliary external electric heater Adds that little bit of extra heat on those few coldest days. Also helps to balance the system size by balancing out those few extreme days. These heaters are installed in the supply air duct outside of the unit. Mostly used on horizontal style equipment.
  • Flow centers - pressurized Circulates the fluid through the unit and the geothermal loop field. These types form a completely closed system.
  • Flow center - non-pressurized Circulates the fluid through the unit and the geothermal loop field. This type of system uses an expansion tank that can be topped off should the loop require it due to thermal expansion.
  • EWC zone control These highly sophisticated controls work with dampers in the ductwork to create multiple zones throughout the house. You can utilize one unit, but have different temperatures in each zone. The control panel controls both the unit, and the zone dampers.
  • Unit air pad (plastic or foam) The unit air pad creates a buffer between the unit and the home. This buffer prevents any vibration from the unit to be transmitted into the home which improves the already quiet operation of the unit.
  • Electrostatic filter (washable) This type of filter is a permanent media filter that can be washed from time to time as needed. This eliminates the need to buy new filters.
  • Electrostatic 24 volt air cleaner This type of filter uses an electrically charged media to increase filtration performance. This improves indoor air quality by removing more particles from the airstream. This filter requires the occasional media replacement.
  • Disposable pleated filter This type of filter uses a pleated media to remove dust and other particles from the air stream. It is important to check these filters regularly and replace them as needed.
  • Air handler (hydronic) These multi-positional air handlers are specially matched to our split systems for maximum performance. The match also qualifies the system for the 30% U.S. federal tax credit. The air handler can be installed in remote parts of the home, or hard to reach areas where space is at a premium.
  • "A" coil (hydronic) The specially matched "A" coil allows the split geothermal system to be added to an existing air handler or furnace in retrofit applications. Additionally, the "A" coil can allow the system to operate in a dual-fuel application where backup heat is supplied by a traditional furnace.
  • Radiant floor distribution systems
  • Consumer purchase plans With a wide variety of payment options and terms, our consumer payment plans make installing a geothermal system easier and more cost effective. By deferring your initial payments out, you can start enjoying your new system earlier and take time to obtain many of the various rebates and tax credits offered.
  • Lifetime warranty coverage The ultimate protection for you and your new system. Allows for one-time replacement of compressor and all-aluminum microchannel air coil for the life of the unit.
