"I had a new AC and Furnace installation done. Like the review before me, I had thermostat issues at first. The owners and workers are really very nice people. It was a bit of a hassle scheduling because they had to come out to St. Peters 3 times. However, I was confident that they would get it fixed for me, and they did just that!! Everything is working great!"

"very professional service and completed in a timely manner"

"They replaced the furnace and AC for a reasonable price. They seem like good units."

"Fantastic!! We had never had our ducts cleaned or sanitized. To my knowledge it was the first time ever and our house is 24yrs old. I can breathe again and the dust that is normally there 3 days after cleaning is gone. Nothing like before! The man explained all of my options clearly and did an amazing job. It was alot of work since we had just about everything done except the dryer vent because it is brand new. Kevin was on his own for the day as his helper was sick and he still had a good attitude and did a spectacular job. Didn't leave a mess either and cleaned up great before he was finished!"
