Atlas Home Energy Solutions is committed to providing the highest quality home energy improvements to homeowners interested in reducing their utility bills and improving the comfort of their home year round. Customer Satisfaction is our number one priority and we promise that we can make a real impact in your home in a way that keeps you happy every step of the way.

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

Super Service Award Winner 6 Years in a Row!! Special Pricing for Angie's List Members on all Insulation jobs. Energy Audit work! Veteran Owned & Operated, Family business focused on Exterior Upgrade Packages, Energy Efficient Improvements, Siding, Roofing, Windows, Doors, Gutters, Insulation, Efficiency Auditing, Decks, Screened Porches, Additions, and more.

"Hired them to do a BGE home energy audit, and Larry Tennant performed this for the company. This included an inspection of the attic insulation which resulted in a lot of ceiling drywall essentially coming off the joists, multiple nails popping through the paint. I was really unhappy with this new problem, since what was supposed to be a $100 energy audit now led to damage that would cost several hundred dollars to repair. From Larry's point of view, the ceiling drywall likely had pre-existing problems making it vulnerable to damage from the inspection, something he had no way of knowing. After a lot of discussion, Larry contributed $500 toward the costs of fixing the ceiling, a reasonable compromise for both parties since the drywall already appeared to have pre-existing issues. Through the experience, he was professional, responsive, and was 100% committed to finding a mutually agreeable solution months after the audit was completed. Even though I would have rather never gone through the experience, I have the highest level of respect for Larry's integrity and commitment to customer satisfaction. I would gladly hire him again if we needed his services again."

"American Home Contractors and Hugo in particular were great to work with. We had multiple jobs done which required several trips and Hugo kept us informed and worked around several weather delays. He relocated and installed a new attic fan, hooked up the bathroom fan to a new roof vent, insulated a pipe in the attic, installed apron flashing on four windows, painted the flue vent, reconnected some lose siding and replaced three pieces of rotted trim and painted it. The work appears to be top notch and we appreciate the hard work and long hours Hugo put in! I would definitely recommend this company and most certainly Hugo to everyone. We also had American Home Contractors replace our gutters and install gutter guards. They did an excellent job with that as well."

Insulation questions, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Winterization includes blowing out water, shutting off the system, and insulating exposed components to prevent freezing.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

Yes, guiding choices between open-cell and closed-cell foams based on needs.
