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."

"I spoke with Alvin at about 9 AM on a Wednesday and he had a team at my house the same day. I had three plumbing issues and Eric and Bryan were able to fix them in about two hours. They gave me an estimate before they began work and that is what I ultimately paid. The team was efficient and courteous, and I was pleased with both the work and the fact they were able to come in a short time. I thought the charge was reasonable and competitive. Based on this work I highly recommend Alvin’s Plumbing and Heating/AC."

"Quote was straight forward and extremely fair to remove a tree from my yard and ultimately replace part of my exterior sewer piping. They even graciously waited while I went through the review process with my insurance and honored the original quote. The work was then expedient, professional, and thorough."

At Total Remodeling, we're more than a remodeling company, we're your partner in creating a home that reflects your family's style, comfort, and needs. We've been dedicated to delivering high-quality home improvement services to families throughout Connecticut and Massachusetts. Our commitment to excellence is rooted in our use of premium materials and expert craftsmanship. From energy-efficient windows to durable roofing and secure doors, we provide solutions that enhance the beauty, safety, and efficiency of your home.

"I had Total Remodeling handle several projects in my home, and when Nick came out, he helped me budget everything in a way that made it affordable without settling for cheap quality. Nick came out and was extremely thorough. He even showed me hidden damage from a bathtub leak behind the wall that I didn?t know about. They completely changed both of my bathrooms, and I was finally able to get rid of that outdated 1970s pink look, and the results are better than I expected honestly. They also helped me out with my front door, and I was able to completely customize the door and added new windows on both sides of it. About two months later, I had Nick back again to do my roof and gutters, which also came out fantastic. I couldn?t be happier with the work, I have no complaints, and I?m already looking forward to having them back in the spring to redo my kitchen!"

Install Boiler questions, answered by experts

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Costs depend on issue severity, parts needed, and labor rates.

Boilers are used mainly for central heating, and water heaters are used for ordinary household water use. In fact, a conventional boiler works best if your home already has a water heater system in place. Sometimes a boiler can be combined with indirect water heaters. But there are also premade combination boiler heaters.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
