Best Annual Maintenance in Buffalo NY

Mark did an awesome job for us. Ver courteous and great customer service skills. He showed me the problem, so I will know what to do. AGAIN, thanks Zenner n Ritter for your quick response, Mark completed the job in a short time. I hope ppl read all these positive reviews...yes, sometimes costs may be high, and sometimes its low, but I never went wrong with zen n rit. Merry Xmas and Happy New Year. Fran

Steve was great. Efficient but thorough, and came in an emergency. Highly recommend his service.

I had no heat during that super cold spell we had. I called on Saturday morning and that afternoon Paul and Bob came to my house and put in my new furnace. They put a tarp down covering my floors from my entrance all the way to the basement door. They worked the entire time they were there and cleaned up everything when they finished. Needless to say we’ve been toasty warm ever since. I would highly recommend this company they truly care about their customers.
