"From start to finish, NETR did a fantastic job. I met 3-4 other vendors, and they didn't come close to NETR's responsiveness, professionalism, or timeliness. NETR earned my business before I even got a quote from some of the others. The salesman, Mark, arrived on time, was respectful & attentive to what we needed, explained our options well, and provided a competitive quote before he left my home. NETR also offered a 5-year 0% interest loan for the project (via a relationship with GreenSky). It took only a few days to schedule installation. The installers were prompt, professional, respectful of our property, and did an excellent job installing the electrical components, compressor, branch box, and 5 heads. They did a nice job of consolidating and hiding the lines on the outside of the house. This past year, we've worked with many contractors, some good, some terrible, so I can compare. NETR was one of the best, and I would hire them for my next project in a heartbeat. "

"We were in the market to convert off oil and switch to a heat pump system. CRM Green Energy Consulting helped us every step of the way. They arrived on time and were very professional during the home assessment process. We agreed to the proposal and set up a time for installation the following week. Throughout the whole process CRM was communicating with us on progress. There was a placement issue for one of our mini-splits and one of CRM’s Carpentry team members came out and opened a wall and patched/painted like they were never there. Super friendly team members and very knowledgeable on green energy and home heating efficiency. At the end of the project they sat us down and taught us how to use the phone app for our GE mini split unit. They helped us fill out of MassSave rebate form as well! We couldn’t be happier with CRM Green Energy! We are so glad we chose them for our heat pump project!"

Heat pumps rely on evaporation and condensation processes. The unit transfers heat through the system via a compressed refrigerant. The compressor within the pump circulates the refrigerant through two coils. The first coil evaporates the refrigerant and absorbs warmth from the air. The refrigerant then passes to the second coil, where it condenses, and the unit releases the absorbed heat.
A well-installed and well-maintained heat pump lasts an average of 12 to 20 years. Routine filter changes, annual tune‑ups, and prompt repairs help the equipment reach the upper end of that range, while skipped maintenance or poor installation can shorten its life and raise long‑term costs. Ask your heat pump installation pro for maintenance recommendations so you can get the maximum benefit from your unit.
Heat pumps are most effective in regions where winter lows remain above approximately 40°F. Efficiency starts to drop below that point and falls off sharply near 25°F. If you live in a colder area, look for a model with a high Heating Seasonal Performance Factor (HSPF) and plan on supplemental heat during deep freezes to keep energy use in check.
The biggest drawbacks are the upfront cost and poor cold-weather performance. Installation can require electrical upgrades or duct changes, and once temperatures fall well below freezing, the unit may need help from a furnace or electric resistance coils. Factor in those add‑ons, along with routine maintenance, when you weigh the long‑term savings against the initial investment.
