Struggling to keep your home at a comfortable temperature?

March 10, 2019

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!
