  • How long do HVAC units last?

  • What's a ductless mini-split system?

    A ductless mini-split system is an alternative to traditional heating and cooling like central air. Ductless HVAC works similarly to central heating and cooling, except that it doesn't require ductwork. Your mini-split system will have an indoor and outdoor unit, but it'll only require a small hole cut through the exterior wall. Inside your home, the air will be conditioned and returned to the room by the same unit. Have any questions for our HVAC contractors? Call Richard A. Davis HVAC, LLC today.

  • How do I know when it's time for an AC replacement?

    As part of our annual residential contract, we help with all repairs and other services necessary. Our HVAC contractors can help you identify when it's time for a new unit.

  • What are the benefits of a programmable thermostat?

    "Programmable" means you can adjust on-site and set the temperature to change at certain times. With the "Nest" feature, you can change the settings from your phone remotely.

  • What are the most common signs and symptoms of needing a new system?

    Our HVAC contractors can take a look and help you determine the need for a new system, but if you're curious, here are the most common ones to look out for.


    1. Your energy bills are going up.

    2. Your interior air quality isn't great.

    3. You're spending quite a bit on HVAC repairs.

    4. You're not comfortable in your own home.

    5. Your HVAC system relies on fossil fuels.

    6. Your HVAC system has an air conditioner that uses R-22 freon refrigerants.

    7. Your HVAC system is aging.

  • What's the difference between R-22 and R410A?

    R-22 is the old refrigerant that has been phased out of use. R410A, the new equipment, is more environmentally friendly and less costly to homeowners. If you'd like to learn more, give our HVAC contractors a call today.

  • When is the system considered aging?

    A system in the aging stage is 10 or more years old, per our team.
