Gas Furnace Replacement In Mountain Top, PA 18797

“From the initial call to the final install, every employee at K.O HVAC both in the office and out in the field was professional, courteous, and efficient. I especially want to highlight Steve, who went above and beyond to help get our system up and running quickly, just in time for an incoming heat wave. His professionalism and clear communication made a stressful situation much easier to deal with.
Steve and Adam even came out early on a Saturday morning, when they didn’t have to, just to make sure our home would be cool and comfortable for my wife, kids and even the dogs. That level of care and dedication really stood out.
I honestly could not recommend K.O HVAC enough. They deliver excellent work and truly care about their customers.”

Gas Furnace Replacement in Wyoming, PA 18644

“Received quotes from 3 local HVAC company's on replacing my heating and air-conditioning units. After speaking with Cody I decided to proceed with K.O. HVAC. When Cody and his crew arrived they were very professional and courteous. The work was completed in a timely manner. They removed all debris and cleaned up afterwards. I would highly recommend K.O. HVAC plumbing and heating to anyone looking to having any HVAC work done.”
