“When starting up our central air last week we ran into an issue where we knew it wasn't working. We called Jack, he came out quickly the next day and unfortunately gave us the news that we'd need a new unit. He is extremely professional and kind. He gave us an extremely reasonable price and had us up and running a few days later with a new unit. Jack is very responsive to his customers needs, and does great quality work. I would definitely recommend him to anyone looking for repairs or maintenance with their heating and cooling needs.”

“Was real pleased and impressed with Jack when he replaced our furnace. I got several quotes on the project but went with Jack because he seemed straightforward. Jack was flexible with timing and put the furnace in a week earlier than we planned. Jack put the furnace in, in just four hours. I would recommend Jack for anyone’s heating or cooling needs.”

- Greg S.

“Mr. Kiefer is an exceptional person. Very small job, cleaning dryer vent and reconnecting venting as they came loose. In spite of that, I received top-notch service. Knowing that I was grieving the recent loss of my husband, he would not accept any payment from me: ‘I was only here 15 minutes. It wouldn't be right.’”

- Mrs. “Dale” L.

“Awesome work, Glad to have an honest local business you can count on to get the job done.”

-Jeff S.

“He did things at a fair price and did exactly what he said he would. He was very responsive to our needs and was able to explain what he was doing and how things worked. We are very happy with Jack's work and his prices. We recommend him to anyone that needs service on their heating.”
