UPDATE: I had an electrician come by to look at a wiring issue for something else. Something told me to check Confenergyâ s work. We paid over $1000 to have our bathrooms vented in addition to the insulation work. They never performed this work. I have a call to them now but with their history they probably wonâ t return my calls. I donâ t know what happened to this company but donâ t use them. Please. I used this company a few years ago for my townhome and we were very happy with them. This year we moved and noticed that the house was very cold so since we were so pleased with this company before we used them again. WRONG!!!!! The sales pitch with Pedro was fine and what he thought we needed to Be done to make the house warmer especially the r bedrooms was new insulation, fixing where the bathroom exhausts come out and few other minor things in the attic. We were eligible for the Dominion Energy Rebate program. We were told we would get our rebate about 6 weeks after the completion. The crew came out at the end of Nov 2023. I was told that the rebate would be taken out of our final payment to the Confenergy. The crew came and did their job but insisted on full payment before leaving (this was like at 8 pm when they were done so the office was closed). My mistake was paying them. I thought because this company was been so forthright previously they would still be. MY MISTAKE. It is now over 2 months later. Brenda the accountant hasnâ t returned my calls. The receptionist while nice told me now my check is coming from Dominion and can take up to 6 months. Pedro the original salesperson and the person in charge of the Dominion Rebates was supposed to call me to get me access to a portal to let me see my status of my rebate. He has not done so. And the kicker?! Is my house is still cold

From the start of the estimate with Jon to the insulation project with the Team Leader Carlos, the project went well as expected. Jon was very professional and knowledgeable. He did not try to up-sale services I did not need, and I appreciate his honesty. Jon went over the appropriate insulation for the attic and the garage ceiling to bring our home to a comfortable level. Carlos and his crew did a great job communicating with me while performing the insulation. Carlos immediately notified me of a leak he discovered from the attic fan and temporarily paused the work on the attic and moved to the garage ceiling insulation while I addressed the leak. As a customer, the only comments/suggestions I would give to the crew is: (1) make sure they keep their tools and materials off the lawn (2) make sure the plastic wraps from the materials they use and trash does not get blown away to the neighbor's yard/driveway, and finally, (3) ask the homeowner which bathroom the crew can use while on-site. Overall, I am very happy with Comfenergy and their service. In fact, I have already recommended them to a curious neighbor.

We had Confenergy blow insulation into our attic and it really has made a difference in keeping the heat out in the summer and in through the winter. Their team came in and sealed all gaps, covered all ducts, and blew in a thick blanket of insulation that has settled and compacted over the years to improve the barrier.

Response from Company:

Thank you for the great feedback and review. We love to hear when our clients can feel and see the results of the projects we get to work on.

A total disaster. An inexperienced, untrained crew created more issues than I had before they began their work. My goal was to increase comfort levels in my senior-living, one-level home built on a slab that is super cold in the winter. I hate as a senior being taken advantage of. I was very naive. I have spent thousands and now am having to throw more good money after bad to try and make my home comfortable to live in. It is so bad; I am ready to sell! And I can not afford to after all I have spent, without taking a loss on the sale. They dense packed my walls and now I am colder; in the process, they removed the flashing above my windows which now leak. I had to hire a window installer to replace the flashing that their incompetent crew removed. They failed to put back the siding properly, so it was hanging off my house. Once again, I had to hire a handy man to refasten the siding the crew removed while dense packing. And the dense packing was useless as it did not enter the cavities that already had batt insulation. While spray foaming triangle boxes, boots, and plenum, they sealed off all my dampers resulting in zero air flow. They reluctantly came back and had to dig out the dampers that they had foamed over. In fact, they over-foamed at junction boxes, boots, and plenum so that HVAC techs could not even tune my system. There is 2 feet of foam, yet hot air is rushing out of the flexible ducts that were not sealed properly. Yet there remain gaps on my boxes, boots, and plenum. Just today, a HVAC tech walked me around the attic, and I could feel the hot air rushing into my attic at the junctions, boxes, boots, and plenums that are all wide open; that I paid to have sealed. I almost threw up; I am heating my attic! And the tech said it looks like a dog was in my attic as the Comfenergy crews failed to put back my blown-in fiberglass insulation they removed when trying to foam, so there is no insulation at the boxes and boots. They were simply careless and failed to rake it back and even out my insulation resulting in further cold spots I did not have. In short, I now will have to hire another company to blow in more insulation and make sure it is even, so I do not have cold/hot spots. Additionally, they left the lights on in the attic, did not replace the attic access foam barrier, and failed to seal the major penetrations including light cans/recessed lights and supply vents I paid for. Next came the bathroom exhaust fans; they were installed improperly and did not vent because the outside flaps remained closed, while inside a cold draft came in my bathroom because the foam sealing, I paid for was not done properly. So now both my bathrooms are drafty. They were cold; now they are cold AND drafty. The HVAC tech today remarked he felt badly that I have two or more space heaters in every room, including the bathrooms! I strongly recommend carefully watching the crew if you ever choose to allow them to do any work for you. I trusted them. And I regret that. I was naive. I was cold. Rather I am still cold! I trusted their salesperson. The crew that did mine were either let go or quit. In fact, one of them still calls seeking to do side work. I politely declined. I suggest you do the same and seek a competent company that you can trust, does the work you paid for properly, and does not damage your home.

I am so impressed with Comfenergy. The sales rep explained why we only needed to improve the insulation at the top of our unfinished basement walls, not the whole thing as another company recommended. So it was considerably less money than we thought we’d need to do the job. Brent and his assistant arrived on time to do the work and were so quiet that we weren’t inconvenienced in any way. I definitely recommend this company.

Response from Company:

Tracy, Thank you for your kind words. It was a pleasure getting a chance to meet with you and help resolve your concerns. Stephen - Comfenergy
