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 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 They completely changed both of my bathrooms, and I was finally able to get rid of that outdated 1970s pink look, and the results are better than I expected honestly.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 most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

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.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

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.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
