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.

John and Manny are the best, when we had AC issues they were able to get out to us in less than 2 hours, even when we called on a Sunday morning! They are very professional. John was also able to save us money on future maintenance. Had our AC fully running again in less than a half hour! Cannot recommend them enough!

What a great company! I called at 2 AM today ( Sunday) because my AC was not cooling. I am older & live in South Florida. It was so hot in my house. John ( licensed AC repairman) answered the phone… listened to my troubleshooting & advised me what to do next with my unit. He set me up for a 9 AM appointment this morning ( Sunday). He was punctual, efficient & knew exactly what to do. My AC is working great!! Once my previous AC company’s Service Contract is up… I am switching to John & 1 hour AC! You should do the same! My neighbor came out while John was working & he was so impressed & is also switching to 1 Hour AC! Thanks for a job well done & on Mother’s Day!!!
