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, Inc., is a locally owned and operated plumbing company that has been servicing Western New York since 1995. If your toilet is plugged, we can fix it, If your sewer is backing up we can repair it. Is Drain running slow? No problem, we can clear it. We can do it all from whole house remodels to drain cleaning, sewer repair, toilet and faucet installation. For your convenience, most of our plumbing calls are completed in just one visit. That's because we feature a service truck that is really more of a rolling warehouse. Every truck is stocked with the same high-quality parts, supplies, state-of-the-art equipment and tools, to repair virtually anything on the spot. Give us a call today!

"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."

"Terrible, technician left and I still had a leaky sink. Said that I would have to make another appt. “Bullied” me into getting a $800.00 garbage disposal two months prior to avoid pipes clogging, two months later, same clogging !!! Technician went in my basement and told me I needed a new sump pump. Cellino is trying to get as much money from me as they can, without finishing their repair work. Never again. Horrible customer service and technicians have absolutely no idea what they are doing."

"Mike Nichols - the owner, did a top notch job from the time he came over to evaluate the leaking from my 28 yr old furnace, estimate repair cost and options to replace it, to doing the actual install yesterday with his associate Rick. Extremely professional, polite, personable, thorough, extremely detailed resulting in a very, very clean install. Mary from Mike’s office is also very friendly and efficient! Highly recommend Mike and Precision Heating & Cooling!! Adding to the review I did in December 2023 after the furnace install. Today (5/23/2024)Precision Heating & Cooling installed the new air conditioner as it needed to wait for the warner weather. Once again, Mike Nichols and his assistant did a top-notch job. Completed it within the estimated time window, very clean job from the furnace to the outside AC unit. Due to Mike's obsession with ensuring any wires, pipes etc he installs are very neatly tied down, he even tied down some long hanging cable wires I was just resting on the hanging ceiling. Now all tightly, neatly secured!! Highly recommend Mike Nichols and his company."

His estimated 3 day repair was done in 2, and the fact that he started on a holiday Monday meant I barely missed any use of my work from home office, which is one of the rooms he worked in. The repairs were done exactly as I’d hoped. I only wish I had done this earlier. I never expected the process to be so easy. Definitely use Nickel City Repair.

FAQs for thermostat installation and replacement projects in Buffalo, NY

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
