(review) Mobile Home Initiative FAQ

1. What is a ducted whole-home heat pump?

A ducted whole-home heat pump is a high efficiency heating and cooling system that provides comfortable temperatures throughout your entire home using the existing duct work. It consists of an outdoor unit and an indoor unit which replaces the furnace. The two are connected by a line set which carries refrigerant, allowing for both heating in cold weather and air-conditioning in hot weather. Heat pumps are able to provide efficient heating in cold climates even at outdoor temperatures as low as -22°F.

2. Can heat pumps heat a whole-home without backup even in extreme cold?

Yes. Properly sized, and selected, heat pumps can heat a home, without backup, down to temperatures as low as -22°F regardless of windchill.

3. What types of homes qualify?

Currently, single-wide mobile homes on Efficiency Maine’s Eligible Towns for the Mobile Home Initiative list.

4. How do rebate-eligible models compare to ineligible models?

In general, rebate-eligible units are capable of producing heat at colder temperatures and are more energy efficient.

5. Can I remove my existing mini-split heat pump to qualify for the Mobile Home Initiative?

No.

6. Do I have to remove my current heating system?

Yes. Your current heating system will need to be removed in order to utilize the existing duct work.

7. Why are my electric bills so high during the winter months?

The bulk of annual heating costs occur during the winter months so it is natural that electric bills are elevated with the use of a heat pump. However, your household no longer has kerosene or propane bills to heat the home, allowing for potential net savings on winter heating costs. If you feel as if there is something wrong with your heat pump, contact your installer and see if they can visit your home and ensure that the system is working properly.

8. Why doesn’t my heat pump allow me to turn it down below 60-62 degrees?

Some heat pump systems prevent users from setting the temperature below 60-62 degrees to prevent frozen pipes and other complications.

9. What happens if my home does not qualify after the initial site visit?

The efficiency of a heat pump system can be reduced significantly if the duct work, underbelly or insulation in your home is not in good condition. If your home does not meet the program requirements, you will be referred to the Efficiency Maine weatherization program for recommended improvements, such as insulation upgrades and air sealing. If improvements are made, the home can qualify for the program provided funding remains and all other requirements are met.
