Reliable Heating and Air has provided me with a wonderful stress free experience. Everyone from the initial service tech, the sales staff and the installers have all been extremely professional providing a high quality experience. Everyone was timely and took care upon entering and exiting my home. Each step of the process was explained and work completed timely. Enjoying my new system and this nice COLD air.


Thank you Caleb Elliott for servicing our water heater. We are ready for winter! Caleb was very personable and did a thorough job servicing our water heater. We appreciate Reliable's commitment to service and keeping things running for us. Every service person we've had has been top notch. So glad we chose Reliable to take care of us.


Forrest Paron was our Reliable rep and he did an outstanding job! He was able to offer us a great price, fabulous financing and immediate installation. He even had the estimates we'd had done several years back to reference. We are very pleased! Thank you!


Excellent service!!! The whole staff was very professional. My furnace was installed quickly and the company made sure everything was brought up to code.


If someone needs air conditioning, I will highly recommend your company. Thanks so much!
