Testimonials
“I had some aging equipment that needed to be replaced. Jeff was honest about what needed to be replaced, unlike the other companies. I would highly recommend and will be using them to do the preventative maintenance from now on.”
— Tim W.
“Jeff spent a TON of time diagnosing and getting to the bottom of multiple HVAC issues on a new home I purchased. Jeff showed me the issues, showed me how to keep them from happening again and REPAIRED rather than REPLACE where he could. Jeff is thorough, thoughtful and his vast experience made it a no brainier to call him to start the repairs on my new home. I will be calling Jeff for annual maintenance to make sure my stuff doesn’t break but if it does, he’s still my first call. I highly recommend for all of your HVAC needs.”
— Brent O.
“The blower in our furnace (which also blows our AC) quit in June. We had someone come out and look and they indicated we needed to replace the furnace, which would have cost thousands of dollars, we needed to give them a retainer and they couldn't schedule before October.
I asked Jeff Hayden to come take a look and in ten minutes he had diagnosed the issue as a short in the wiring and had it fixed a few days later.
Jeff will be the only person I call next time I have an issue.”
