Randy and his crew are awesome. Professional, competitive pricing and quick and efficient work. He didn't try up selling me on the best furnace on the market. He made sure I was getting the furnace and air conditioner that was best for my home and gave me all the options out there. I didn't feel like I was getting a sales pitch. Also, had him recently do some service on the humidifier (that he didn't install) that was acting up. Called him and he made sure that I got fit in ASAP.

Randy Sir and his assistant did an awesome job installing our new HVAC system in November 2019. In less than 8 hours they installed two new furnaces, evaporators and A/C condensers in my home and made several improvements and upgrades to other small components of the HVAC system such as the ductwork, gas line and condensation pump tubing.

Randy was very responsive with my follow-up questions in the weeks following the installation. The price for my new HVAC system was about 20% less than a few competitors that I checked.

I strongly recommend Sir Heating and Air!!

Sir heating was able to come out on a Saturday morning and get our furnace started for us. It was an easy fix and he did not take advantage and try to sell us something we did not need . Service and pricing were excellent! Thank you Randy
