Wonderful experience with Residential. We just completed a replacement of our air and heating system, on time and on budget. Since we're on a hill, the install was a bit more complicated, yet the Pro's at Residential were undeterred. They've maintained our system for years and we are so pleased now that the new system is up and running in time for winter. So much better.
We'd like to give a special shout out to David, Andrew and Matt, Jessie, Nick and Noah. 2x for Noah for painting the conduit to match the house paint.

We've used Residential Heating for almost two decades now, and they are truly a cut above the rest. Here's an example: technician Hassan just left our house after our regular scheduled maintenance today. Most repair guys sort of mumble “everything’s OK” as they’re slinking out the door. Hassan’s customer communications with us have always been Way Stellar. First a top line view ("Everything looks good."), and then a bit of a window into the future ("As the systems get toward their end of life we’ll do a cost/ benefit analysis if something bigger fails in the system.") and then an actual

I had a recent terrible experience with this company. My main issue is that their rep came to my home and insisted that I needed a full replacement of my system. When asked why? "He explained, " Because your system takes R-22 and that coolant was phased out in 2019" I asked if there was any left to be purchased. He stated no, I quickly fact checked that info only to find out that R-22 will be phased out 2020 and is still available and it the cost online was 17.00 to 33.00 a pound. When I showed him the information on my phone he backed up and then stated that they could get R-22 but it would cost

We had an electrical issue that damaged our furnace. Even during these strange times. Jim was dispatched within an hour. Very appreciative for his professionalism and commitment to customer service. The team in the office were great too. Will definitely use them to upgrade our HVAC equipment. If you have problems, call them ASAP!

We couldn't be happier with the air-conditioning system installation we just had done by Cathy and her team. Cody and Eleazar were prompt, courteous, professional and finished the job in 2 days! They also took every precaution to assure we were all safe during these difficult times. This is the second good experience we've had with Residential Heating and recommend them highly.

Ten years of excellent service. Recently a compressor failed and Residential responded quickly to install a new compressor. Thank you.

My first encounter this company was when I had a leak in my furnace. They responded promptly and the representative was very professional and attentive.
Then I went shopping around for an AC, it seems to be hard to compare between Residential and other companies that came by for the estimation. The representative (Nick) was professional, thorough and honest. The professionalism continued when they came to install the unit, with great attention to details by the crew. Later on they followed up sending their representative to assist passing the city inspection.

My contractor friend has been using Residential Heating and Air Conditioning for years, and he recommended them to me. They replaced 2 heating units for me in two different properties and I am very satisfied with their competence and customer service. Cathy, Trina and the technicians are all experienced professionals, and working with them is always a positive experience. I highly recommend them!
