If you are building a new home or thinking of replacing your current electric forced air furnace, you should consider making the switch to a ground source heat pump (GSHP). GSHPs work by pulling heat out of the earth and moving it into your house, concentrating that heat and disbursing it within the living space. The key to a GSHP’s efficiency is the fact that it doesn’t make heat like a traditional furnace, rather it moves heat from one place to another which uses far less energy than burning a fuel source or converting electricity to heat by means of resistance. GSHPs depend on the fact that at a certain depth, the ground temperature stays relatively constant.

If you are thinking about upgrading your current heating system and would like to have whole house air conditioning for the dog days of summer, consider installing an air source heat pump in your home. Heat pumps have come a long way since their introduction. The efficiency and performance of today's air source heat pumps is one-and-a-half to two times greater than those available 30 years ago.

Ductless heat pumps (mini splits) make good retrofit add-ons to houses with "non-ducted" heating systems, such as wall heaters, baseboard heaters or in-floor radient heat.  Ductless systems provide heating and cooling, and do so more efficiently than any other room-size units.  They can also be a good choice for room additions where extending or installing distribution ductwork is not feasible, and very efficient new homes that require only a small space conditioning system. Be sure to choose an ENERGY STAR® compliant unit and hire an installer familiar with the product and its installation.

Like standard air-source heat pumps, mini splits have two main components -- an outdoor compressor/condenser and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units.  Installation is easy and only takes about a day.  MEC currently pays an $800-1,200 incentive for a ductless heat pump that is added to a home with electricity as its primary heat source.
