Corey was kind, knowledgeable, and went above and beyond to get our furnace in working order. Professional and reliable company.
The installers were kind and very professional. The wore booties over their shoes to protect my floors.The installers were here most of the day installing a new heating and air system. They didn't leave a mess or a sign of them being here.I would highly recommend Wallace Heating and air.

My elderly parents had been having problems with their 15 year old furnace/heatpump/AC. New Comfort had serviced it recently and gave them a quote to replace it, $16,400!! Plus told them they were buying Wallace Heating & Air! I contacted Tom, who had installed their old system, he came out and his quote was so much lower than New Comfort. Wallace was able to install the new system that week. The tech's were polite, professional, and patient with my aging parents. I'm very happy with Wallace and their entire team and a special thanks to Becky and the office staff for squeezing us in!
