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."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"If I could give R. Pelton Builders, Inc. negative stars I would. I have worked with many contractors, architects, engineers and developers in my life good and bad. R. Pelton Builders, Inc. could be one of if not the worst company I have ever had the unfortunate privilege to work with. After signing up with them, they wasted almost 2 months of my time, misrepresenting timelines and expertise, mismanaging the process, communication and making multiple false statements along the way. I was clear from the outset that the time frame install the system was critical. They told me multiple times that permits had been filed when, in reality they never filed them at all. They did not even know the process to file permits in my town (another thing they had represented they had experience with) and did not even contact the town until the week we had initially targeted for the install. They told me they understood and had experience with Solar batteries. I had to design this part of the system myself because they had no clue what they were doing and were not even capable of effectively working with the vendor to design and solve for any issues that arose. They were terrible with communication, often telling me they would get back to me and never doing so. I had to chase them all the time. When you are spending any amount this would be unacceptable. I was spending over $100,000. 2 months into the agreement, after bailing on a site visit that I rearranged my schedule for, Michael P then called me to state that they would not install what they had agreed to and that Steve P (the owner) was no longer going to offer batteries as he did not trust them. But then I should just do the solar alone with them. I was clear from the beginning that the point of the project was to have a back up system not just a solar system. It seems to me that their plan from the beginning was to tell me what I wanted to hear and then pull the rug out from under me when the timing was such that I was in jeopardy of losing the full Federal Tax Credit and potentially the State incentives in hopes that I would adjust the install to solar only. Ultimately, they gave me no confidence that they were going to be able to successfully and properly install solar either. In my option and experience they are not to be trusted. My experience with them is that they are incredibly disorganized and inept, often gave me false and misleading statements and have real issues communicating at any level that would be considered acceptable. They also showed zero respect for my time or following through on what they had committed to do. All of this resulted in me losing time, money and expending a tremendous amount of effort for ultimately no reason. Simply horrendous on every level and I could not recommend a company less then R. Pelton Builders, Inc."

Energy Efficiency Auditing questions, answered by experts

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
