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.

“Dishon was a professional well informed gentleman. Now, installation on a new thermostat for $397.00 plus $77.00 for coming out is simple ridiculous on any level. Remember I'm only changing thermostat and not having to rewire. As any smart consumer would say, No Way. I bought a new thermostat at Lowes for $49.99. Installation is $125.00. Unfortunately I can not recommend your company moving forward. Positive side; i give your employee 5 stars.”
