Follow-Up to Air Source Heat Pump Workshop

Follow-up Q and A to Heat Pump Workshop on 11/18/2013

Where can I view the presentations on air-source heat pumps?

What are the first steps towards investigating a heat pump system for my home, rental property, or business?

 Before you install a heat pump system, ensure that your building is weatherized properly.  There’s an adage: “The least expensive BTU is the one you never use.”   If you do not know how to measure the efficiency of your building, contact Bruce Whitney of the NeighborWorks H.E.A.T Squad at 802-246-2111.  He was an exhibitor at the workshop.

The next step is to find a certified heat pump installer. Here is a link to Efficiency Vermont’s approved list of certified installers:

When you contact a potential installer, ask how many ductless heat pumps they install annually and their level of familiarity with this type of product.

What information should I gather for an initial consultation with an installer?

Be clear on your intent for such a system.  For example, do you want to supplement your fossil fuel, biomass, or resistant heat (electricity) use, or have the heat pump be your primary heat source with another system as a back-up?

Have information about your building (square footage, insulation values if known), type of HVAC system (oil, propane, gas, biomass), and equipment model numbers, if possible.  Historical utility bills are helpful for estimating energy savings.  Most manufacturers have tools on their websites that will help with equipment selection as well as energy estimation. Here are links to Mitsubishi and Fujitsu’s websites: (offers a savings (ROI) calculator).

 What is the cost range for a heat pump system?

For a 12,000 BTU unit, the installed price could be approximately $2,500 to $3,500.

How do I determine the number of units/capacity I’ll need?

 There are industry rules of thumb (i.e.: 400 sq. ft./ton or 30 BTU/sq. ft), but it is best to leave equipment sizing to the contractor, as things like insulation values, window type, and ceiling height may affect the equipment selection.  Oftentimes, a good starting point is examining the size of the existing HVAC system and how well it has performed in the home.

What resources can Efficiency Vermont provide?

Homes, rental properties, and businesses that meet specific eligibility requirements are allowed to take part in the Cold Climate Heat Pump (CCHP) Program, which provides financial incentives for installing heat pumps. This program is only available to customers located in the former Central Vermont Public Service (CVPS) territory.  Information on the program, including eligibility requirements, can be found at the following link:

  1. If the duct work has standing water, wash it out with clean water.
    In accordance to market standards and the attic insulation guide, the R-38 is highly recommended.

    The filters are compact, well-informed, shockproof units designed to clean the air from the following contaminants:
    Radioactive dust, nuclear fallout, Biological agents and All known war

  2. When used as insulation material, it is harmless not merely to the home occupants but to the installer as
    well. This means beginning with the attic as a lot of
    heat is lost with poor insulation. Some items may be easily seen by the lay person,
    but you will want a professional inspector to review the home and all its components to get a
    complete picture.
