"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."

"Joe and Larry were wonderful! We bought a new house that needed work, including a serious issue with how our water heater was installed (without a pressure release valve!). Joe came by and looked at it all and because the situation was dangerous he and Larry came the very next day. Their estimate was clear and the job came in at the estimate (with one small additional nal.repair they found taking a part the toilet.). They walked me through everything and made me feel at ease. These are our new go-to plumbers!!"

"recently had the pleasure of working with Joel for an AC diagnosis and repair, and I couldn’t be more impressed with the level of service provided. From the moment he arrived, Joel displayed a high level of professionalism, courtesy, and technical expertise that immediately put me at ease. He quickly identified the issue, clearly explained the problem, and outlined the steps needed to get everything back up and running. What stood out the most was his thoroughness and honesty throughout the entire process. Joel didn’t just do a quick fix—he took the time to ensure everything was working properly and efficiently before he left.

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

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.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
