We Promise Five Star Service

Polite and Very Knowledgeable
“Mike came by to give me an estimate. He was polite and very knowledgeable. He gave us a bid for a better furnace for less money than another company. There is an excellent chance we will be booking our installation because of Mike and with Betlam. We already know that John Betlam is a very reputable company from friends who do business with them.” – F.C

Great Experience
“Your service man was a perfect gentleman and explained everything. Because of him, we signed a service agreement. Great experience.” – T.B.

I Wish More Companies Were Like Yours
“I am a former customer of Lang. I’ve continued with your company and am very satisfied with the service I have received over several years. It can be uncomfortable having strangers in your house, but I have NEVER felt that way with your employees. I wish more companies were like yours.” - K.K

Dedication and Professionalism

Would Definitely Recommend
“The power goes out way to often in our neighborhood, and with a little one at home, we didn't want to risk not having power. Ever. Steven and the team at John Betlem made the process of getting a generator installed very easy and at the right price. They were very responsive, friendly and did a great job of keeping us educated and informed throughout the process. Would definitely recommend.” - S.W.

Very Professional and Friendly
“Very professional and friendly. Very thorough. I needed a new furnace for my 92 year old mom. They came out that day. Installed within 2 days. Would recommend them to everyone.” – S.E.
