    “Bryan designed a replacement system for my home. The old system was too small and seriously drawing tons of electricity, effectively causing a big chunk of my $1000 PGE bills in the summer. What I have now is a perfectly balanced system with the proper duct work and zones to keep my 4000 sq ft home very comfortable, while lowering my PGE bill at least 35%. He also arranged PACE financing, which was painless, quick and easy! Thanks again to Bryan and the entire crew!”

    “Thank you Certified Carl!! We cannot thank you enough for your outstanding service! We needed a new ac and furnace and like magic they were installed and running in less than 24 hours! (I run a home-based preschool and an ac is a must during these hot Summer months!) Your professionalism and customer service were above and beyond what we expected. Your speedy installation was greatly appreciated. We will be referring everyone we know and don't know to Certified! ”

    “Called these guys at the end of the week since our AC was not cooling the house down at all and our second floor was awful. The receptionists were friendly and helpful. We were able to get guys to come out this weekend and take a look. We didn’t get great news, but we were walked through the process step by step and given a list of what was needed and costs for each. We didn’t feel pressured to sign anything, but we signed abd felt comfortable doing so. We need our AC to work! Very grateful for the great care and service! Thank you Lucas, Chris, Kim, and Maggie and rest of the staff!”
