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."

"The company deserves 1000 stars l. Chris came and gave a well thorough inspection and estimate of my actic. Had my concerns and expectations, I had several other companies come and give quotes for double the price. Especially ORKIN. Orkin tried to use care tactics to sign contract without any explanation. Chris gave the quote and the crew arrived a week later as scheduled. Chris has a great work crew who were professional , caring, and did high quality work. Every step of the way, I was communicated and was filled in. I was shown before , during and after photos. And end results were UNBELIEVABLE Chris is fair and honest, he gives reasonable prices and will not take advantage of his customers."

Our cleaning procedures are in full compliance with the industry standards from NADCA and ACCA. Not all duct cleaners are alike. Our techniques involve far more than simply air whipping your ducts.

"We are having our HVAC replaced and our salesperson recommended DUCTZ. DUCTZ came out on-time today to clean our air vents. The communication prior to the visit was very clear and it was easy to understand the upcoming process. They were very considerate, we toured our home and they went right to work bringing in the needed equipment and moving necessary furniture to access the vent covers. They were diligent and stayed focused on the task. Before I knew it, they were reattaching the cleaned vent covers and removing the equipment. Within a few hours, we had before/after pictures and have a great sense of comfort knowing all the gunk is gone! I highly recommend DUCTZ!"

Insulation questions, answered by experts

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”
