I have used Mike and Jason for nearly the 25 years I have lived in Louisville. They have replaced several systems for me and I shopped them each time. Safe, reliable, straightforward and trustworthy are just a few terms that come to mind. Like most HVAC companies, they sell and service particular brands because they have grown to know and trust those companies. Like themselves, they deal with hard working middle-priced units and they have worked great for me. They don't sell Lexus or Acura, but if you want a reliable Honda or Toyota, they got what you need. They also don't oversell. They are happy to talk options over with you including repair vs. replace. Good luck!! read more
