The first time our furnace was leaking water. He fixed it for not much money (I don't remember how much), warned us if it happened again we'd probably have to replace it, and that was like a year or more ago. All has been fine. The second time was the first really hot day of the year. Our AC stopped working. He came out right away, did a great, fast, and very competent job, and fixed our problem for $200. I trust this guy.

After pulling everything out and drying it up, we found it was leaking from our garbage disposal. Fortunately, we are members of the Cardinal Care Club, so of course we called Cardinal.

He gave me lots of options and explained different benefits of each. He really knows his stuff. By 9:10 am Ken had completed i still, cleaned up & was on his way. Well done!

And their communication is quite good. Maybe that's where the extra $5k is required!!!.... Complete BS

Special note about Mike Hoffer (the owner), he was incredibly helpful, responsive on the first or second ring of my call and assisted us choose a unit and answer many questions through the weekend; and they were able to get a new unit installed for us within 2 days. It's a small company with a small crew but their customer service was excellent; pricing seemingly competitive. I definitely recommend this small but very competitive for HVAC system assistance.
