"Friendly service. Was on time and blew insulation in attic over garage. Perfect transaction!"

"The entire process from estimating (Kenny) to project management (Walter) to team members (four), was efficient, respectful of our property and extremely communicative. The team went multiple extra steps to make sure our crawl space free of entry points for critters while installing all new insulation"

"I hired Acorn Attics to insulate my house and I couldn’t be more happy with their work. Phil and his crew were on time, friendly and incredibly hard workers. He worked with me on scheduling and made sure to keep our project moving even when we had a setback with another repair. I highly recommend them. They will get the job done. Thank you Acorn Attics and Crawl Spaces!!"

"I used Boulton Insulation and they were fantastic. They were efficient and there was little to no "dust"."

"My 20 year old furnace died on a cold Thursday evening and I got online to find a company to replace it. After entering my contact info, I immediately received a text message from the company's owner, Casey, making himself available for me if I wanted to talk by phone. I had him call me, and he checked in to see what the problem was, what I wanted to do, and to be sure I had heat for the evening. He even offered to drive space heaters to my home if needed, even though he was at least 45 minutes away. He then scheduled to meet with me at my convenience the next day to look at my home and discuss options. During the meeting, Casey was very personable, knowledgeable,and professional about the products and services his company offered and helped me design a heating/air conditioning system to replace my old, inefficient furnace and wall a/c and insulate existing ducts. He also referred me to my utility company to see if rebates were available, which there were. The workers who installed the products were pleasant, professional, and skilled and ensured that their work met the city's requirements so that I was eligible for the rebate. I am very happy with the products and services I received from them and would recommend them to anyone having problems with their heating/air conditioning units or looking to upgrade to more efficient systems.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"Good quality work, completed in a timely fashion and a fair price. Their cleanup was also thorough and they even stacked old cedar shakes for our later use. I really can’t think of what more we could ask. There was a mixup with our neighbors’ roof, but Pro Cover even dealt with that professionally."
