3 Best HVAC Services in Buffalo, NY

Recommended by my neighbor who just had their furnace replaced. Everything from start to finish was fast and easy with Zenner and Ritter, and a good deal cheaper, too. They scheduled me for a consult same day and were on time. Jimmy the salesman/tech was very friendly and knowledgeable. Install team (Shelton) was friendly, fast and on time. All while a couple thousand less than any other company I called. Can't ask for more than that.

Quick and professional service. As the GM of Stellar Roofing who takes a lot of pride in our customer service I can say that my experience with this company was top notch. Would absolutely do business with them again and recommend them going forward. Thank you for getting Dominik out here quickly. He fixed my problem quickly and charged a fair price for the work performed. A+ across the board.

This company is friendly, knowledgeable, did a great job, I recommend. And Sean is super friendly, and a great guy really knows his stuff. He put in a boiler along with Mike who is very friendly also. I am happy, and looking forward to doing business with them in the future. And I would like to give a shout out to Maria, who coordinated and put the whole thing together.

Woke up to a freezing house on the coldest day of the winter, called O’Donnell Heating at 8am and they had someone out to us within the hour. They check our furnace out determined we needed a new furnace and showed us why. Gave us options and advice on best unit to install and even has options for financing. Then the guys that came to install were professional, nice and worked fast and efficiently. They explained everything to us and finished within 3 hours. Heat back on within a total of 5 hours and they even moved a bigger job to get my family heat (3 children at home). Best part was the owner called us and told us they would gave me the higher end/energy efficient furnace at the same price as the lower level/energy efficient furnace. You have a heating or cooling problem in WNY, call O’Donnell Heating and Cooling if you want your moneys worth.

O'Donnell really saved the day for me (and saved my bank account)!! My furnace quit, and because a sticker was on the furnace I had, I called a different company in the WNY area who tried to charge me an exorbitant amount. I called O'Donnell while the other guy was at my house, and they gave me a WAY better price and were here within hours. Nick, Dean, and one of the other O'Donnell employees were fantastic- very efficient, very friendly, and very knowledgable. Two hours later, my new furnace was in and I was very impressed. I have already recommended them to my family and friends! Will definitely be a return customer!

Dawn and Tim were very polite and professional. My heat went out Tim came right over diagnosed the problem and everything was installed by the next day . The two installers were also very professional and courteous. They installed the new furnace in a few hours. Did a great job. I would recommend ODonnell I’ll be using them again for other projects.
