What does the One Hour mean in your company name?

If we do not show up within that window, your service call fee is waived. 1. Express Appointment: This is an appointment that is scheduled during a specified one-hour time slot. You are promised that a technician will arrive at your home within this one-hour time window. You will also receive a call when the technician is en route to your home. 2.

You will also receive a call when the technician is en route to your home. 3. Standard Appointment: This is an appointment that is scheduled during a specified four-hour time slot. You are promised that a technician will arrive at your home within this four-hour time window. You will also receive a call when the technician is en route to your home. 4.

Emergency Appointment: This appointment is for an unspecified time after normal business hours Monday – Saturday and all day on Sundays/Holidays. Calls are dispatched in the same order they are received. You will also receive a call when the technician is en route to your home.

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.

“Brendan worked tirelessly to diagnose and fix our furnace that, of course, quit working during the two weeks where nightly temperatures dipped to single digits. We very much appreciate his determination and diligence to get to the bottom of our furnace's issue. Thanx also to One Hour Heating and Air for getting on the schedule the same day we called.”

“Hello, I’m Jason Murphy logged into my gaming account (lol). I’m here to leave a fantastic review for my HVAC technician today from One Hour Heating & Air. Neil Randolph did an outstanding service maintenance for the winter season tuneup and inspection. He was very professional, knowledgeable, and walked me through everything he was doing prior to getting started. I highly recommend him to anyone who has a need for service and / or repairs for your HVAC system. You won’t be disappointed. Thank you to Neil and One Hour Heating & Air for helping take excellent care of all our home service needs! I wish everyone a very blessed day and 2026!”
