It was bumped up against a copper wire and literally melting. He quickly repaired that, explaining as he went along. Discovered some other glitches and needed to come back a second time, in 2 days with an ordered part that he replaced. Now the heater is working correctly and that was well worth the money. I liked the office staff and their excellent communication skills. Highly recommend their service.

Great service and friendly staff. I've been using them since 2006. They have my trust.read more

Mike & his roofing crew are some of the hardest working guys I know. They worked on my 1920's…read morehouse complex roof and did an excellent job. Great job with clean up too. I'll use them again. I can't speak as highly about the furnace dept however. I used them a few yrs back & was very happy. But this time around, I had the furnace cleaned & serviced (as it was old) to the tune of $160. Kept smelling something gassy, called the gas company (3 hrs after the service), they red tagged it & turned it off. Said I could have been killed in my sleep as the exhaust was being blown thru the vents. When I called the office, the manager listened but offered no solution or reimbursement of the service call. Guess the $160 is worth more than the $3000 sale on the new furnace. So a BIG yes on the roofing dept & a BIG NO for the heating dept. from me.

We used this company before and was happy with the service, however now 2+years later they are not!…read more We had an issue with cold air leaking around the system they installed. We asked them to come out to look and fix if need be. The technician came out but not able to "fit" (their words not mine) and could not fix the problem. They told us we had to call another company to come fix the issue. To add insult to injury we were charged $175 for this "service". We called the office to question and the lady was so rude, didn't care about this issue, and was nasty. I will pay for this non service, however I will never use this company again, and when recommending when asked will turn away ANY and ALL to from this company.

My elderly sister was taken advantage of by Advanced Energy…read more She left $450 cash an envelope for a $430 service call. They took the full $450 and did not leave the $20 change. They did not leave an invoice or receipt. Worse, her heat pump was under warranty, but they still charged her for the part. This is exactly the kind of thing that makes people distrust service companies. An elderly customer should not have to worry about being overcharged, having cash kept, or being billed for warranty parts. I would not recommend Advanced Energy

Absolutely incredible company, the owner Israel is so kind and extremely efficient!!…read more I requested an estimate on Monday & the job was scheduled for Wednesday. (Today!!

We hired Capitol Duct because they were the only company we called that used a scope (camera) to…read moreexamine the ducts before cleaning. We should have gotten the ducts cleaned before installing an in-duct booster fan, but we didn't think of it, so we needed the cleaners to be extra careful with their rotating brushes in that area. They came out 3-2-26. We asked for photos of the fan. Did not receive them. We asked them not to use the fungicide but they did. Both requests were clearly typed right onto the Case Report. (Once we found out the type, we learned it wasn't as dangerous for sensitive people as we had thought.) The dryer vent was supposed to have a pre- and post-cleaning flow test per the Sales Order, but the results weren't reported. This cost a grand. I wasn't going to write a review at all until I saw what was on our filter only 9 weeks later. Today 5-9-26, we went to change the filter and found piles of crap on it... my husband threw it out before I could get a picture ... but this is some of it. I actually have an old ad that shows the prices charged for this kind of service 10 years ago... I used to get the ducts cleaned yearly back then. Now it is 20x more and far less dependable, obviously. Oh, and they tried to upsell us an Air Scrubber, too.
