Testimonials

I just wanted to say thank you to the gentleman who took my call over the weekend. The advice was perfect and I am sure glad to have had the answers he provided. The oil burner is going strong, and I can't say enough good things about AHS. Almost 15 years and the boiler is working as well as new, and you even provide phone support on weekends to customers who bought from you a decade and a half ago. You are a wonderful company.

Daniel K.

They are excellent people to deal with. They are trustworthy. They treat you like family.

Darlene F.

Just want to say what a great product you make. I purchased an s260 back in May of 2014, and just got it installed... and runs like a champ. You make an awesome product, thank you.

I found the adjustment, maintenance and cleaning of the Coal Gun boiler to be easy for a mechanically-minded, do-it-yourselfer.

My days of getting up in the middle of the night are over, thanks to the E-140 Woodgun boiler! My expectations for this boiler have been surpassed at every level. It is easy to operate, easy to clean and easy on wood. My only regret is that I didn't buy one sooner.
