Is your HVAC system more than 10 years old? Are you making frequent repairs or enduring hot and cold spells in certain rooms? Don’t wait until the system dies. Take a proactive approach and have its performance evaluated by a professional.

Aiming to replace your HVAC system before it actually fails will ensure that you have time to price and research options.

To prevent your utility bills from rising along with the mercury, consider installing a programmable thermostat or learning how to use the one you have now.

By tailoring your air conditioning (or heating) to your schedule, programmable thermostats can save both energy and money!

What Our Clients Say

I just had all new ductwork and a new unit installed at my home. The whole experience was a good one for me, first thanks to the tech who carefully explained what I needed and why and who came back later after the work was completed to make sure everything was up to snuff.

Yesterday we had new heating and air system units put in by Mountain Air and Heat. There is more even heat. We like also the credible looks of the units and the relatively short hours it took to install it all. Looks like a great job and we are very happy. Thank you!
