"Recently, during the cold spell, our boiler began acting up, turning on intermittently with just a little nudge each day. After reaching out to several companies for estimates, we chose M&R to replace our 50-year-old boiler. Tom was the first to arrive to assess the situation and provide an estimate. Once we decided to move forward, M&R was responsive and punctual with their appointments. The team handling the installation consisted of Dex, Jake, Josh, and Tony. They were professional, respectful of our property, and made sure to clean up the area around the boiler. The installation was completed in one day. Tony also stopped by twice to check on the progress and made adjustments to sync up our zones. We are very happy with the work and professionalism of the entire team and are glad to recommend M&R to anyone in need of heating repair or replacement. "

"We couldn’t be happier with our new central air HVAC system! Our old system broke down during one of the hottest weeks of the summer, and Ricardo and his team came to the rescue. They were incredibly accommodating for what was truly an emergency situation. From start to finish, Ricardo was responsive, professional, and communicative. He took the time to thoroughly explain everything to my husband and me, and made sure we were comfortable with the new system before wrapping up. The installation process was fast, efficient, and impressively neat—his team showed great care and attention to detail. Truly outstanding service and workmanship. Highly recommend Ricardo and his team to anyone in need of HVAC work!"

We joined Angie's List in August of 2007 and have earned their Super Service Award every year since 2009 when they started that program. HARP Home Services, LLC is here to take care of all your heating and air conditioning needs. Whether you are looking for a free quote on a new central air conditioning system or are ready to install radiant floor heating or a new boiler for those chilly winter months, we're just a phone call (or e-mail) away. Residential & Commercial.

"We had a furnace installed by Harp on July 8th 2024 after it being diagnosed by their technician as to the reason our ac system was not functioning properly. That’s when our troubles with Harp began. The installation was not done properly, we needed 3 service calls to get the ac to work properly. The installers were sloppy. We cleaned up screws and wire and parts from the old furnace for weeks. When heating season began we noticed that the humidifier installed with the furnace was not operating. We scheduled an appointment to have it repaired and they called the day of the appointment and told us they couldn’t come that day and we had to reschedule, so reluctantly we did. They finally came and repaired it. From what the technician told me it was not wired properly. On January 21st 2025( the coldest night of the year) the furnace stopped working. We called Harp to get someone to come to repair it as we had no heat in below 0º weather I was told the best they could do is to come the next day between 2 and 6 pm. I tried to explain that this was an emergency but to no avail. I called my local oil company and they were at my door within 30 minutes( which I would’ve expected from the company who sold us the furnace) the repaired it quickly and told us that one f the wires on the control panel was not attached properly. It cost me $300. I would NOT recommend Harp to anyone. They are not reliable and do not stand behind their promises of service 24/7. Stay as far away from this company as possible. We are sorry we ever started with them."

My name is Tom Mull of Mull Bros. Oil, a family-owned heating and cooling company in Wethersfield, Connecticut, where I was born and raised. There’s no doubt that you have seen many changes with the heating oil industry in the past decade or so. While many companies have given up or, out of desperation, have changed their business philosophies, we intend to be here for a long time. As a matter of fact, we’ve been around for over 60 years. My father, Bill Mull, started this company in 1945. At a time when stove-oil was in great demand and #2 fuel was being introduced as a home-heating fuel, Bill decided to get in to the delivery business. In the early 1950’s many oil burners were being installed on coal furnaces. Being mechanically inclined, Bill learned the art of installing and servicing the many styles of oil burners and heating systems.

"Said I was too far for a smaller job, and rather than try take advantage was genuine and honest and provided many good tips. Extremely nice and helpful --- just too bad there not in the neighborhood"
