"Paul Kittel came out on an emergency basis on a Saturday and helped me figure out where the problem was. Santina was incredibly helpful, as always. She is a treat to work with. Paul was able to get me up and running and suggested some additional work that he will be doing next week. This organization has the best customer service I have seen in our area. I highly recommend them."

At Roy's, we understand how stressful it is to lose plumbing, electrical, or heating and cooling comfort. And while we can't always prevent that stress from happening when those breakdowns first occur, we can give you a great experience that takes that stress away fast. Creating a worry-free service experience takes teamwork, resources, and skill. It also takes dedication from every technician, plumber, and customer service representative we have, all working with the same purpose: to make your repair or install as easy as possible, as quickly as possible. But it goes beyond good service. We're dedicated to giving back to our community, as well. Every month, our Roy's Cares program makes a $500 donation to a local charity, and each time a technician places a lawn sign at the end of a job well done, we donate $5 to another monthly charity recipient. It's just one way we dedicate ourselves to our city and the people in it, both in our business and beyond!

"Rep (Tyler) arrived on time. Was very personable and professional. Evaluated and completed repair quickly and without issue. I’m very happy with the results. (Note…Angi categorized project as a broken pipe when actual issue was wit an on demand water heater.)"

Cellino Plumbing, Heating, Cooling & Electric is a trusted home services company serving Western New York. With decades of experience, we specialize in residential plumbing, heating, air conditioning, and electrical work. Our locally owned and operated team is committed to delivering reliable service, upfront pricing, and top-notch customer care. Whether it’s a routine repair or a full system installation, Cellino’s licensed technicians bring comfort and peace of mind to every home we serve.

"I’m reluctant to leave a negative review, but my recent experience with Cellino has left me no choice. I initially hired Cellino for a greenhouse HVAC project, based on a positive recommendation and previous great service with a furnace issue. On September 6, Chris came out to assess the job, spending significant time taking measurements and photos, and assured me they had handled similar projects. After weeks of visits and reassurances, we received a quote on September 18. Though it was higher than others, I trusted Cellino based on their professionalism. However, on October 22, over a month later and after multiple assessments, the installation team informed me that the heater they specified was actually overpowered for our greenhouse—news that should have been caught early on. This oversight led to weeks of back-and-forth exchanges, ending with us exchanging the heater for a more suitable model. This delay has cost my business thousands in lost stock due to inadequate heating."
