    Customer Review

    By Christian B.
    Leesburg, VA

    I had a great experience from Brenda and her crew at Comfenergy to fix a problem that has been in my attic for many years. My townhome is in Leesburg, VA and the air handler is high up in the attic, so every time it is hot and humid outside, the AC cool air forms condensation outside of the ducts and then drips down three flights to the basement, pools on the drywall and ceilings, that led to rot and mold. Comfenergy explained and educated me in full detail how to fix by closing up all the small gaps around the ducts, bathroom and kitchen exhausts, reduce heat in the attic from the roof with a heat barrier, and put in cellulose insulation to fill all areas that help reduce energy bills. I would recommend Brenda and Comfenergy for anyone experiencing a similar problem.

Project Location: Sterling, VA 20165

Comment: Hi, I'm interested in home insulation and sealing improvements in my 1985 home. I am also interested in air duct testing and sealing if that is a service that you offer.

Project Location: Ashburn, VA 20148

Comment: Upstairs bathroom fan vents to roof through attic. Water is collecting in the duct and leaks through the bathroom fan. We are pretty sure this is due to uninsulated ducts and would like an assessment and quote from professionals.

Project Location: Ashburn, VA 20148

Project Location: Round Hill, VA 20141

Comment: Need to insulate my basement walls, maybe flooring and ceiling.

Project Location: Annandale, VA 22003

Comment: Hi, I have a home built in about 1973, wood construction, large single pane windows, with a very uninsulated, and very obviously unsealed attic. The heat on the second floor that rises, but also emanates from the hot ceiling, is my main concern. I also have a dark brown roof which will remain that color. I also have a single stage AC 3 ton unit that is not very effective in balancing out the temperatures amongst all three floors. A balanced heat distribution is also a challenge. I had an home energy audit done about 7 (?) years ago, and I can provide those results. I'm interested in another home energy audit, the one you offer for I believe it's $250, to see what the cost would be for various energy upgrades. Although a lot of things I can do myself, I'm at the point I think I'd rather pay somebody else to crawl around in my attic. I am very familiar with building science and have followed many of the home energy website and blogs.
