"Following discovery and repair of a roof leak, I needed to have my existing attic insulation removed, and new insulation installed. I received several quotes, and decided to choose Prudent based on David's timely and professional communications, honest appraisal of what the job would entail, and competitive pricing. David and his team did an excellent job throughout the process. They arrived on time, used drop cloths and plastic covers to keep everything clean, walked me through the process and progress, and shared pictures of areas I couldn't easily see or get to myself. At the end of the job, they thoroughly cleaned up all debris and left the house and property as they had found it. We discovered a minor issue later that evening, and David sent a member of the team out to fix it the next day. Excellent communication and work - very happy with the end result, and would hire again in a heartbeat."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"The job went as quoted was , everything was great as I expected . The team was very hard-working and professional. They cleaned up and I could not tell they had been here. They were able to get everything done in a day. Other quotes I'd received said it would take 2 days. I am so happy to finally have the old blown insulation out of my house"

"I found Positive Energy and Patrick Michaelyan on Angies List after meeting with and getting estimates from several other insulation contractors. I selected Positive Energy for this job because Patrick has BPI certification, he gave me several alternative approaches and reasonable prices for each of them, and because of Patrick himself. We discussed the attic portion of this job extensively, primarily the pros and cons of sealing and insulating the attic floor vs. the interior of the roof. Patrick was patient and candid throughout the process, and never pushed higher-priced options. He has a strong knowledge of building performance issues, particularly regarding energy use and efficiency.
I have to emphasize that this was a difficult and unpleasant job. The attic of our house is very low - barely enough height to move around on hands and knees, and ductwork around the perimeter makes getting into the eaves extremely difficult. Cleaning out the old insulation was required because (as we learned only after we moved in) the attic had been occupied in the past (fortunately, not currently) by raccoons, whose mess had to be removed. Bottom line is that Patrick spent the better part of two weeks on his hands, knees, and belly, wearing a respirator, to clean out, seal, and re-insulate this attic. The only access to our attic is through a closet in the master bedroom, so he had to set up equipment every morning, and take it down and clean up every afternoon. I can only conclude that he loves his work, because this was a nasty, dirty job, and he was pleasant, patient, punctual, and professional every day. He did the work for a fair price, never tried to up-sell or add anything unnecessary, and did a first-rate job. Though we have done other work done that also contributes to the reduction, our energy bills this winter have been 25-30% lower than the previous year, even though this winter has been significantly colder. I strongly recommend Positive Energy.

"First, there are a lot of dubious roofers out there. We wanted a GAF Roof System with a 50 Year Warranty. American Home Contractors was the only one that was Master Elite Certified by GAF to install a 50 Year Warranty roof in our area. A lot of roofers said that they were, only to find out by the regional GAF Representative, that they were intentionally/unintentionally misleading. It is conceivable that quite a few people out there think they have a warranty, that won't and will find out from GAF that the number one reason they don't is because their installer wasn't certified to do so. Stop right here. American Home Contractors is the one of the very few Master Elite Installer in area. Shaun coordinated our installation. He is the very best at what he does, which is answer your questions honestly and make every request that we made to the owner. From the very first meeting to the signing of the contract to the day of and after the installation, he patiently and promptly answered all of our questions and addressed all of our concerns. Most that we got estimates from focused exclusively on the shingles, but if you want your shingles to last more than a few years, you need adequate ventilation in your attic. Their was a small miscommunication about the day of the installation, but they more than made up for it. We have a very steep roof (11/12 pitch). The day of the installation, the Carlos and his crew put down tarps and thoroughly cleaned after each day. Because the roof was large and pitched, it took two full days and a few hours on the third. The second day was Thanksgiving. That is right, they came out on Thanksgiving to finish but were a few shingles shy of completion. These were Slateline GAF shingles. They are not on the shelves at your big boxes and have to be ordered. But Shaun and his supplier were able to find a pack locally and delivered on Saturday before a big storm was moving in. They crew showed up, finished installation, and we were sealed tight well before the rain started. Everyone was polite and professional. The financing could not be easier. I would not hesitate to do it again. Thankfully, because of the warranty, I won't have to. We have other exterior projects, and these guys have more than earned my loyalty. I will give them first option on those projects. They also have 0% financing for 18 months. This was the longest of all roofers we received estimates from. American Home Contractors is top notch, you absolutely will not be disappointed. A new roof is a major expense and a potentially stressful renovation, but these guys made it a minor hassle. I am sure that all of their staff are great, but ask for Shaun. Probably don't need to ask for him, he likely will be your guy and you are going to be very happy at how easy he and AHC make this for you. Best Regards!"

"Debbie, the AC&R salesperson, was very knowledgeable and confident. They were the 2nd quote I got for work and came in even lower than I expected (which gave me pause as a low bid is a red flag). But true to her word, they did the work professionally (mostly...see below) and promptly. While I had another company do the energy audit for the Pepco rebate, AC&R took over the work, did the blown fiberglass one day and the spray foam the next.



For the blown fiberglass in the attics above our additions, they added spray foam (from a can) around any gaps per the contract and foam board baffles at the soffits. The installer noted that all our soffits were blocked and the batting insulation was too wide for the rafter channels, so he leveled it out as best he could to ensure an even coating of blown insulation. At the end, he sealed up the gaps between the attic and our to-be-finished upstairs (cape cod style, so all one room).



For the spray foam insulation, the team came in the next day, and I had to be out of the house due to fumes. I did come back around noon as they expected to be done well before then. They didn't know I came in and I went to the back of the house to watch TV on my work break. The one annoyance was during their cleanup, one of the installers came down into our kitchen and then saw me. He said he was looking for a vacuum cleaner to clean the stairs. I told him don't worry about the carpet as it was getting pulled up, but this was the one piece of unprofessionalism I noted above. Contractors should NEVER use the homeowner's property; they should bring their own tools, including vacuums!



While the spray foam can get very messy, they kept the splatter mostly contained to inside the crawlspace, not the finished flooring. However, I was surprised that they didn't tape off the outlet covers or light switched. since the particles are so small, we're going to have to replace the switches/receptacles at our cost. Also, there was a storm door screen that wasn't covered and now needs cleaned. Basically, I think they should have taken more care in covering the very few items we left upstairs and the outlets/switches.



They didn't spray around the window frames (large gaps where window weights used to be) because the open cell foam would expand too much. If I wasn't there, I think they would have just left, but it was clear in our contract discussions they needed to insulate those spaces too. They used a few cans of "Good Stuff" equivalent, but didn't fill in the gaps entirely. It did the job well enough, but it's a ding against them as I expected more preparation.



Lastly, I thought that AC&R would walk me through all the scheduling and final "test out" (for the Pepco rebate), but I had to contact them and schedule with someone different each time. They were always prompt, but I expect the experts to know to do this for/with me rather than expect me to know the process. I go through it once in a lifetime while they do it weekly.



While the end of the review sounds more negative than positive, I would definitely recommend AC&R out to others as they're priced right, they have been in business for over a century, and like any contractor, you just need to follow up to be sure everything is done to your satisfaction.

"They pointed out areas of air loss that needed to be covered or blocked and advised  more attic insulation which service they will provide. Their price offer seems reasonable.  I'm still crunching numbers.
