Struggling to keep your home at a comfortable temerature?

One spring, a homeowner came to us with an urgent request for zoned comfort control—especially air conditioning and better temperature control—in the various zones of their home. Their current propane furnace did not evenly heat the home, and the master bedroom and downstairs parlor—with a grand piano—were continually at two different temperature extremes. No cooling was possible at all. A single heat pump with two heads, one in the master bedroom and one in the front room, were not able to heat and cool at the same time.

By installing two separate heat pumps, the problem was solved. We installed a combination system that could provide 90% of the heating needs, at our outdoor design temperature of 19 degrees F.  The most powerful two-head heat pump, by comparison, was only able to provide 75% of heating needs under similar conditions. And with the new system, air conditioning was now possible. The propane-fired furnace was left operational and our homeowner has reported occasional use under extremely cold conditions. 

Overall the homeowner has reported being very satisfied with the new system, with bedroom air conditioning a “Godsend” in the summer!

Own a large home that is expensive to heat or keep cool?

1970’s Home with High Heating bills from Electric Boiler

This is a beautiful 2700 sq. ft. home built in 1978, has moderate insulation values for its large square footage. This 3-bedroom home features separate rooms for both a living room and family room, along with a spacious kitchen and dining room. Additionally, this home has a complete apartment in the basement. 

The previous heating system was an electric boiler with a hot water system going to the many areas of the house, which was very expensive to run with several areas still being uncomfortable at times. The homeowner also brought up that they had no air conditioning as the system was quite old. 

We installed a Mitsubishi 42,000 BTU 5 head Hyper-Heat system with wall units in the two main living areas and the three bedrooms.

Additionally, we installed a separate Mitsubishi 15,000 BTU in the basement apartment.  Due to the size of the home and older insulation values, we needed to provide a lot of heat in the two main areas of the home to ensure it would stay warm in very cold Washington weather.

The Hyper-heat systems will produce its face value capacity or more as temperatures drop to 5 degrees. The 42,000 BTU system will provide up to 48,000 BTU when temperatures reach 17 degrees outside. 

This system uses a branch box distribution center for the refrigerant which increases its capacity and shortens the refrigerant lines.  The separate unit for the basement apartment allows that user to heat or cool regardless of what the rest of the house is doing. 

This system keeps the whole house comfortable year-round and the homeowner reported a 50% decrease in their heating bill! Did we mention that Heat Pump systems also work for Air Conditioning? Their new system provides cool relief from the rising summer temperatures as well as filters the air, protecting occupants from Smokey air outside during summer fires.
