  • 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(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.
  • How often should I service my HVAC system?

    It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.
  • How often do I need to change my HVAC filter?

    Your filter should be changed every one to three months, depending on conditions in your home and your region’s climate.
  • Do you offer purchase financing?

  • What are the advantages of a smart thermostat?

    Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.

    The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.
