“We had an emergency and called A&S. They were busy like everyone else this time of the year. They made time to get out and give us an estimate so we could satisfy the insurance co.
The furnace was replaced 5 days, a beautiful neat job, later at a very fair cost according to the adjuster. She said her estimate was higher!”

He got the job done efficiently and the way it should be done. They have been living here for 30+ years and this service was the best yet. Definitely recommend!”
“I am very pleased with not only the service I received from this company but with the prompt response from them in a time of need. I contacted them very early morning as I had no heat throughout the night and my call was returned within a half hour and a technician was sent out first thing. Scott arrived at my home and was very professional and friendly. The work done to repair my heat was only what was necessary and at a reasonable price. I feel they are very honest and they now have a customer for life! I will highly recommend them to family and friends!”
