Cardinal State

I had a friend recommend Cardinal State, Jim had done a lot of work with Cardinal in the past. They came out in 1hr, they diagnosed the problem in 5 mins. They had all the American made parts on the truck and replaced within 10minutes. Mike knows his trade very well, he knows what he's talking about. I work in construction as an electrical engineer. They did they work safe (lock out all the sources of energy). If you need any AC repair, please call Cardinal they are dependable and trustworthy. Don't mess around with anyone else. Call them. Very reasonable, good quality, good value, Professional, responsive!!!!!

We’ve been using Cardinal State for our residential HVAC service and remodeling for several years and couldn’t be happier with Mike and his team. He is top in his field by any measure and as an added bonus he’s a darn nice guy. You can’t go wrong.

We are so very pleased with the service and the product we received from Cardinal State! Mike and Kim (owners) and Sean (associate) were nothing short of professional on all counts and at all times during the removal of our old unit and cooler, to the installation of our new HVAC unit and thermostat. From our first meeting, we received clear and concise communication from them. The bid we received was comprehensive and fully laid out what we were committing too. They were personable, timely, clean and respectful of our property and our schedules. The biggest headache we had was in coordinating removing our old AC and Cooler units and have a new AC unit installed around our re-roofing schedule. All told, our project spanned a week and required two different roofing crews leapfrogging with Cardinal State to complete the installation. Everything was done when and as described – except dealing with an earlier than expected crane the day of install! We are confident that we chose the right company to install our new HVAC unit. This is one small business that is huge in all areas of product and customer service! We highly recommend Cardinal State for your residential or commercial air conditioning needs.

We have lived in our unit for years and not needed it serviced and probably due to wear and also this insane weather lately we had a system line get clogged which who ever heard of such a thing. Our technician came out last minute call promptly Sean (with an E) and was polite, professional, kind, he was able to explain what was going on in a way we understood. He didn’t just do a lazy check and assume something he took the time to walk the property check the unit and diagnose the issue. Even in Arizona weather. He corrected the issue went above and beyond what I’ve seen previous technicians from other companies do and was pleasant all while doing it. I would absolutely recommend him personally for any ac needs you may have and really would like to tell cardinal that they have a true gem of an employee in Sean. He vacuumed out the area and cleaned it allowed it time to dry while checking lines to make sure it shouldn’t occur again. Advised us on a way to monitor it in the future to prevent something from hopefully happening so quickly. Thank you Sean for your professionalism, your knowledge, your conversation, your kindness, your patience, and your work ethic it was appreciated more than you know from #2 -Sam

I've been using Cardinal State for many years now. They have always been prompt, professional and offered great service. I continue to recommend them to anyone I know needing Heating or AC repairs.

They came and diagnosed an issue on my system. That part of the work was professionally done and I was pleased with the work. They attempted to install a new thermostat for me but where unsuccessful due to larger concerns with the wiring. When removing the thermostat, they broke off a plastic piece and then hid it from me. I found it later on my own when I was selling the item and observed a large broken piece. Very unprofessional to not mention this during the job. Will find a more honest company to work with.

Fast and honest! Kim was so prompt for returning calls and scheduling. Mike was great and very knowledgeable! Highly recommend!!
