Ductless Mini-Split Heat Pumps: FAQ
How do ductless heat pumps work?
Air source ductless heat pumps work extracting the heat from the natural air, and using a refrigerant process to bring it to your desired temperature. If you have a refrigerator in your kitchen, you already have experience with this technology.
A single outdoor condenser unit attaches to up to five indoor air handler units. The refrigerant technology allows you to keep all zones of your house within one degree of desired temperature, all while operating more efficiently than any other traditional heat or AC method.
Do ductless heat pumps work for heat and AC?
Yes, ductless heat pumps work for both heat and AC. What’s even better, is that they cost three times less what it costs to operate either window AC units, or a central AC system for the same size space.
Do ductless heat pumps run on electricity?
Yes, they run on electric but are approximately three times as efficient as electric baseboard heat. In fact, air source ductless heat pumps consistently clock in at the most efficient and cost-effective way to heat your home.
Do ductless heat pumps stop working below 32 degrees?
Many models of ductless heat pumps manufactured before around 2014 would lose significant functionality below freezing temperatures. However, in the years since, Fujitsu and Mitsubishi have been designing and manufacturing heat pumps that can withstand harsh Northeastern winters.
Fujitsu models are rated to function efficiently down to -15°F, and Mitsubishi models function down to -13°F. They can still provide heat below these temperatures, however they do lose some efficiency.
Do I need a unit in every room?
Typically no. For a multi-zone set-up, there are different indoor units which have different output power. So you might put a more powerful one in a living room with airways into other rooms, and less powerful ones in bedrooms with the intention of only serving that smaller room.
Our experts have handled thousands of ductless heat pumps installs, and are well-trained to create a zoned system that is both efficient and comfortable in your home.
Can I qualify for a Mass Save 0% Heat Loan?
Most likely, yes. Residents in Massachusetts eligible for the Mass Save program can usually get financing to cover the cost of their heat ductless heat pumps. The heat loan is no-money down, with 0% interest for 7 years. You can learn more about it, here.
UPDATE: now, residents who are not in territories serviced by Mass Save can also qualify for the heat loan, via the MVP program. Learn more on Mass.gov.
Endless Energy is experienced in walking our customers through the heat loan process both with Mass Save and Home MVP.
Can I qualify for Mass Save rebates if I install ductless heat pumps myself?
No, the heat pump must be installed by a Mass Save certified installer to qualify for Mass Save rebates.
