Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour® technician will walk you through all costs using our Straightforward Pricing® Guide so there are never any surprise fees.

“Jason came and troubleshot and fixed the issue with my heating system in no time. From the time I called (about 11:30 pm the previous night) to the time the problem was fixed by Jason, the total time I was without heat was about 10 hours so you really can’t beat that type of speedy service. Jason was very friendly and accommodating with my dog too, who can be a big pain in the rear end when company comes over.”

“Our service with 1 hour heating and cooling was phenomenal! Our technician, Jason got here within 3 hours of our call and had everything handled. After half an hour he knew exactly what was needed to fix our issues. He drove from York to Lancaster to pick up the parts needed and after returning had our furnace back up and running in 15 minutes. The company was more then willing to work with us for payment and I will always recommend 1 hour heating and cooling to anyone in need. Great service and more then willing to get everyone whatever they need! Jason was the best and very professional!”
