"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"I selected this company because they are a member of my energy provider's energy saving program network. The customer service was top notch and the insulation installation team was top rate. There was a problem with the aeroseal team assigned to seal any holes in the air vents. The aeroseal solution leaked throughout the house, even into drawers, closets, on clothes, everywhere. It took over a month to clean up. Throughout this process, the owners remained in contact and assisted as best they knew how. The cleanup was stressful, but in the end, all worked out and I have noticed an improvement in energy savings. Thanks!"

"We had Xanvria remove the old insulation in our attic, air seal the attic, and install new R-49 batts. They did a really good job, were professional, and explained what they were doing along the way. Everything came out clean and we?re very happy with the work. I would definitely recommend them."

"This guy called promptly to schedule an in home consultation and came promptly the next morning. I received a courtesy call from him saying that he was running 10 minutes behind schedule. When he got here, he was friendly, he evaluated my attic and determined that no insulation was needed. I tried to push him a little to say that we might need a little more insulation up there since that particular room gets colder than others but he insisted that adding insulation wouldn't help. I think others might have tried to get some work out of the visit, but not these guys. I would recommend them based on their honesty, fairness, and integrity."

"I contacted Atlas not because of high energy bills but because of noticeable summertime temperature differences between the first and second floors. My home is 32 years old and had never had the ducts cleaned and I suspected there was leakage from seams in the duct work. While the house was built to the then current (1988) code levels, the code is now more stringent. For example, my attic insulation was R30 where code is now R50. Atlas first performed an energy audit. Based upon that outcome, they recommended: (1) rerouting the bathroom exhaust fans through the roof, (2) additional insulation in the attic bringing it to R50. (3) closed cell foam sealing in the main and garage attics where appropriate, (4) cleaning the heating/cooling ducts and (5) using the AeroSeal product in the same ducts. I opted for all of these services. The work was spread over 3 occasions, each no more than 2 days duration with most completed in a single day. Their friendly work crews were very attentive to my property, made sure to put down drop cloths throughout the house and generally made certain everything was clean upon leaving. They kept me informed throughout every task and showed/explained what they had encountered. My ducts certainly did need cleaning, even though it’s always been a smoke free home environment and without pets. The benefits of this work have been fantastic. The AeroSeal process yielded a 98% reduction in duct leakage. I can tell very little temperature difference between the first and second floors now. I’m expecting more noticeable improvements during the winter months. I strongly without reservation recommend Atlas Home Energy Solutions."
