“One Hour Heating and Cooling is independently owned and was formerly Olathe Heating and Cooling. This is a top notch company and the employees are very knowledgeable, honest, and considerate. They figured out why I was on my 4th air conditioner way too soon. Recently, I had them replace that ac unit, furnace, and upgraded. My 1st question was, "Is this Olathe Heating and Cooling?" They didn't push me to buy, I wanted a bigger unit and the furnace was 30 years old. They gave me a substantial discount for bundling. It's well worth it Outstanding service! Thank you Travis.”

“We were to have another company come out today to service our AC, but they cancelled this afternoon and weren't even sure they could come out by Wednesday. Called One Hour Heating and Cooling, and they had a technician here in 90 minutes. Our tech, Tristen, was very friendly and thorough. We now have cool air and are very satisfied with this company! We will be using One Hour Heating and Cooling for all our heating and cooling needs. We even purchased a plan!”
