Most contractors provide a free quote, make sure to ask each contractor for one. When you’re reviewing quotes, don’t rely on price alone since the quality of the design and installation matter just as much. If you’re replacing the heating throughout your entire home, make sure the contractor performs load calculations. For mini-splits serving multiple areas in your home, it’s important heating loads are calculated correctly so the indoor units are sized for the room they’re serving. When it comes to heat pumps, bigger is not better. Heat pumps that are “too big” can create home comfort issues such as being cold and clammy in the summer and heating unevenly in the winter. What are load calculations and why are they important? Load calculations are done by measuring the rooms and windows (including type and direction) and listing insulation values in attics, walls, and basements. The calculations determine the amount of heating and cooling needed to keep your home comfortable. These calculations are sometimes called a “Manual J.” After you’ve received your quotes, make sure to compare heat pump specifications, efficiency levels, warranties, size, parts and labor. Also be sure to check if your quotes include any improvements to the existing duct system such as adding ducts, duct sealing, or adding insulation. Quotes with equipment model numbers and itemized parts and services will make it easier to compare. Remember, the lowest bid isn’t always going to be the best bid. Here are some questions and tips to have on hand to make sure your contractor will correctly design and install your system. For a robust list of questions and considerations, see our FAQ section .
Contractor Knowledge/Experience Considerations Do you know about available rebates and tax credits, and will you help me apply for them? Will you provide training for me on how to properly use and maintain the system? Equipment Considerations Am I likely to save money on my heating costs and how much might I save? Will you do a heating load calculation? Are you familiar with the Northeast Energy Efficiency
Older homes switching from a fossil fuel furnace may need to upgrade their electric service panel to accommodate a heat pump. Weatherizing your home is a great step to reduce your home’s overall heating and cooling needs which may allow you to skip the electrical service upgrade. When replacing other appliances in your home, look for the blue ENERGY STAR logo. ENERGY STAR certified appliances use less electricity than noncertified appliances and last longer!
Partnerships (NEEP) cold climate heat pump list? What type of thermostat do you recommend?
• See the section on Controlling Your Heat Pump for more information.
Installation Considerations Where will you mount the outdoor unit(s) and how?
• Make sure you approve of the location of the indoor and outdoor units. • Ensure the outdoor unit is level, on a pad, and elevated above the snow line. • See section on Protecting Your Outdoor Unit for more information.
If exterior “line sets” ( piping ) will be visible, where will they be placed? • Make sure any penetrations are properly sealed. Will I need any electrical service upgrades to accommodate the heat pumps? • If yes, will I need to hire my own electrician?
