Brian is very easy to work with, his advise about which gas stove to go with was excellent and my parents ending up going with the high-end Regency model. His installers were very good and were easy to talk to about the job and they did an excellent job. I like it when a contractor works with their customers and cares about their company to back up the work done. I highly recommend them and a special thank you to Brian who runs an excellent company! My parents are extremely happy and can't wait on those cold nights to go by to feel the warm heat of their new stove.

-Furnace
-A/C unit
-Air cleaner and purifier
-Tankless water heater
-Fireplaces (Mantles)
