We installed whole home heat pumps after purchasing our home in 2022, and we absolutely love them! They heat and cool the house so well, and are very energy efficient.

We do not hire contractors for house projects easily. So we know that we would not have installed a ducted heat pump without the help from our Harvard Energy Coach. He was very responsive and gave us the confidence to move ahead. Our oil furnace and  air conditioner were close to 40 years old and we knew we needed to do something soon. After attending the meeting at the General Store in early 2023, we moved forward, starting with the free energy audit and more insulation (most of which was paid for by MassSave).

Our coach provided us with a list of heat pump contractors who had done work in this area and recommended that we get proposals from 5 contractors. He said we would learn something different from each contractor, and he was right. Most of the proposals came in with similar equipment and pricing, so we narrrowed the list down to two to focus on. We ended up choosing Advanced Mechanical Devices because we liked the people that came to the house and that we talked to in the office. We highly recommend AMD.

We are very happy with our new equipment and how it has heated the house this winter (2024). We expect to be happy with the air conditioning, this summer, as well. We got about $5k in rebates from MassSave and it looks like we'll get at least $2600 in tax credits. We also worked with Workers Credit Union to get a no-interest loan that covered the work we had done. They were very easy to work with - and quick!

After 9 years of heating/cooling with Mini-splits, we decided to switch to geothermal heating and cooling. Massachusetts Geothermal was excellent to work with, throughout the process and communicated well. We have been very happy with the installation and performance of the Climatemaster systems, and are enjoying the quality of the climate control. Smooth, consistent heating and cooling that moves the air gently throughout the house and keeps us comfortable all the time.

Earlier this year our heating system failed on one of the coldest days!  We met with Dave an amazing energy coach who jumped into action, helping us evaluate and understand our situation by analyzing our consumption and energy use and then evaluating our proposals. Christie Cooling and heating installed our new heat pump quickly and we were able to get the Mass Save Rebate to cover one third of the cost!

In 2018, under the HeatSmart program, we installed a Ground-Source Heat Pump system for heating and cooling.  One unit in the basement, with new ductwork, handles the first floor,  A second compressor in the basement with air handler in the attic covers the second floor through pre-existing A/C ductwork.  Cooling is much more efficient than our old central A/C.  Heating uses a lot more electrical power, but is still cheaper to run than our old oil-fired baseboard heating (even with more comfortable thermostat settings).

We used Bill Wenzel Heating and A/C for the installation, and Skillings & Sons for drilling the ground-source wells.  Both were highly professional, and we are happy with the results.

Last winter we installed a heat pump powered air conditioner. The bonus was it also provides supplemental heat, which offsets our oil use a little bit. No more high energy window units and we can easily get fresh air too. When the temps get really high, the unit still cools but wont over work, it balances indoor temp with outdoor temps. We are very happy with this home upgrade and highly recommend Advanced Mechanical. 

We installed heat pumps a few years ago when we gave in to adding A/C.  For some reason that I can't explain, the quality of our heat is so much improved  - more even and comfortable.  For the A/C we run it at a high temperature during bad heat waves and the result is reduced humidity - also very even, comfortble and not overly chilly.  We have solar panels and the only downside is the increase to our electrical usage, but that is nicely offset by savings on oil for the furnace.

My house had heat pumps on one side when I moved in, but they didn't cover the other half. This summer I had the a second outdoor unit with two heads installed, and upgraded the exiting outdoor to the more efficient hyper-heat type, which I probably wouldn't have done were it not necessary to qualify for the $10k whole-home reabte.  I do like the fact that I'll be able to use the system for heating now instead of oil, but I have to say my primary motivation was to get AC in the bedrooms that didn't have it.  And on that front alone, it is certainly worth it.   The system cools the whole house quite effectively, even places you would think are too far away from any of the heads.  It's also a lot quieter than I would have thought, which is nice.  I'll probably be switching them over to heating mode soon so we'll see how that goes.  I engaged a few different places trying to get quotes and Denommee was by far the most responsive and organized.  They were easy to work with during the installation as well, so I would definitely recommend them. 

I had worked with Wilson Brothers (Pepperell MA) for many years when it came time to replace the central airconditioning unit we had purchased from another vendor in 2003.    Despite the supply chain challenges of the COVID-19 era, and a challenging attic to work in, they installed a heat pump that provides air conditioning, as well as heat down to 15 degrees Fahrenheit.  Wilson Brothers is easy to work with and kind and professional in all their interactions with me.

The fourth year living in our new/old(1781) home we discovered that our window mounted airconditioners would not keep up with the hottest summer days.  After deciding to "go solar", we then installed efficient Mitsubishi "mini-splits", which not only keep up with the hottest days but also take the chill out of the spring and fall mornings.  We get more cooling for far less noise and we no longer need to install/uninstall our prior window warts.  (I highly recommend doing both solar and mini-splits.  It is very gratifying to know that the sun beating down on a hot day is also doing the work to keep your home cool.)

This spring we installed units that provide heat as well as air conditioning; Acton Refrigeration has been a great resource and did a wonderful job of installing the unit as well as providing excellent customer service.

Our heat pump was a wonderful addition last fall - for heating, of course (SO nice not to rely on the big tank of oil anymore) - but even better, it was really effective at cooling the house during the hot spell in July. Our house isn't vintage - it was built in the 1970s - so we were able to utilize our existing ducting system, and didn't need to install mini-splits. I was worried we would start closing our windows all the time (I love leaving windows open in the summer) - but no need to worry. When the outside temperature dropped below where we set the pump to turn on (78), we just opened the windows to let the breezes and the sounds of the birds in. Go for it if you're thinking about it, you won't regret it!

Just over a year ago I had 3 mini splits (air exchange heat pumps) installed in my colonial-style home:  I upstairs in the master bedroom and 2 downstairs at opposite ends of the house (family room and my office).  The first year has been a learning process for sure, especially given the house has multiple heating zones which enabled me to heat only those areas I was in.  That said, I've learned how to balance heating with the mini splits and am looking into adding at least one more in the addition to the house.  An added bonus:  being able to have air conditioning in my bedroom and office on those very hot/humid nights and days this summer!  Great improvement over fans in the windows!!

We replaced our aging oil furnace with a geothermal heat pump system last summer, and it's kept our 18th century house perfectly comfortable through extraordinarily cold and hot days these last twelve months (even during the -14F, -46F windchill weekend this past February). The system is extremely quiet and requires little maintenance other than changing air filters every few months.

Our gas furnace was in need of replacement. We wanted a heat pump for efficiency and to electrify much of our heating needs. Given the age of our house (over 100 years), which still has the original single-pane windows, we decided on a dual-fuel or hybrid solution. It consists of a heat pump (for air conditioning and heating) with a high efficiency gas furnace as supplemental for the coldest days (if needed).  Our hope is the heat pump will be sufficient to supply the vast majority of our heating needs come the winter heating season.

We moved into our new house in August of 2014. We built the house, and as we worked with the architect to design it, we were sure to specify that we wanted our home to generate as close to zero carbon emissions as possible. As a result, we heavily insulated our home and built it with twelve-inch thick walls and triple-pane class throughout. We designed the house with an emphasis on LED lighting. We also installed geothermal heat pumps instead of a traditional oil furnace and heat our water using a heat pump. Since moving into the house, we've continued to reduce our carbon footprint. We purchased an electric car. We switched over to electric outdoor equipment. We invested in ecological landscaping. We reduced wasted electricity by implementing smart plugs throughout our home. While we are not quite at zero emissions ( we still cook and run our backup generator on propane), we are getting close and will continue to invest in going green in the coming years.

Had 2 mini splits installed at the end of August 2022, and so far I love them. Even produced heat when it was -15 degrees fahrenheit during that brief but brutal cold snap. I have a backup propane boiler, but haven't needed it. In the winter you do need to get the snow off the units pretty regularly. They have their own defrost cycle, but when there's ice build up efficiency drops. A/C and dehumidifier capabilities are also stellar. And the electric costs were very reasonable. 

Over the last few years, we have added several heat pumps, a couple as mini-splits, and the final one using existing ducts that were attached to an ancient and innefficient cooling only system.  We are now heated, and cooled, 100% by air-source heat pumps!  The $10,000 MassSave rebate was great too.  Signed up for a share in a Nexamp local solar farm, which also gives us a 12.5% discount on our electricity costs (until we get our own solar).

We had heat pumps and mini splits installed in March and couldn't be happier. The summer was very comfortable, despite the heat and humidity, and they used considerably less electricity than our LG portable units.

We finished installing our new geothermal heating and cooling system in late March. With summers getting hotter, we are incredibly grateful to have this efficient system to cool our home. We typically dislike using AC unless absolutely needed but this sytem is so gentle, uniform, and quiet, that you hardly know that it is on. This is in complete contrast to the old system which was loud and created cold pockets. Plus, my husband just commented that we were able to sell electricity back to NG in  June because of our rooftop solar panels. I don't think we were able to do this last year when we used our old outdoor AC units for cooling. I think that we will be equally pleased once we use geothermal to heat our home this fall and winter.

We had ground source heatpumps put in under the Heatsmart program back in 2018. You can see the pictures of the big drill that did three bores in our backyard. It was a big project but it took only one summer to put the yard back together and we love the results. The heating and cooling is quiet, efficient and requires minimal maintenance - basically changing filters every 4 months. It is clean (compared to the soot from our furnace) and has been much less cost than our oil heat and air conditioning units. Since the town's electricity is 100% renewable we think it's a win win!. Installer - Bill Wenzel, from NH with Skillings doing the drilling - both were great to work with.

Heat pumps were installed in the new COA building by Classic Construction, and paid for by the citizens of the town of Harvard
