What We Do

Testimonials

Highly Recommended!

Nanette S.

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!

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!

My A/C went out last night and Bryan worked us into his already fully booked day and fixed or A/C!!! Very professional and great work! Definitely will be recommending you to anyone in need of HVAC services!

Brian K.

Certified professionalism, and great prices. The entire team is friendly and helpful. Everyone I’ve met used a consultative, no-pressure approach. Their technical expertise in explaining exactly how they’re going to design a system is the most unique. True service is about helping others, and this company is all about that.

It was awesome working with Brittany and Kristin during the whole process. They made scheduling easy and Brittany came back when we had some questions/concerns. Everything is all good to go! Had a whole new HVAC system, new attic insulation, and new ductwork. The house is way more enjoyable now. We use the system way more than we used our 30-year-old system and the page bill is about the same. It’s nice always being comfortable. Thanks to Brittany and the install team!

Victoria H.

The folks at Certified are great!! Brittany came out and assessed our 35 year old system and we had a new system in a little over a week!! The gentlemen who installed the system were fast and professional. They arrived on time and by 3 we were cool and comfortable!!! Thanks Certified!!
