Get matched with top thermostat installers and replacers in Brooklyn, NY

"We had trouble lighting our natural gas boiler about a month after we suffered flash flooding due to hurricane Ida's heavy rain. The unit's electricity turns on, but the gas was not lighting despite clearly hearing the sparks. I called Mario who was kind from the start, and scheduled an appointment to check the boiler. Mario worked backwards through his checks: the gas valve, each of the wires, the pilot igniter and pilot gas hose. He showed us the gas valve had corrosion and water in it and had to be replaced. He then vacuumed the gas pipes to remove excess water, and installed a new valve; however, after a test, the gas would not turn on. He checked the wires and voltage was proper. He checked the igniter pilot, and discovered the flame was not lighting - gas was not reaching the pilot; the pilot gas hose had to be unclogged. Once he did that, the unit started working again! Mario was very detailed and patient in his approach. He has been pretty honest and kind, and it shows through his work. He made sure to test the boiler works properly with different thermostat settings, and also checked the heat radiators were working and heating the rooms. He made sure we did not spend more than necessary by explaining exactly what need to be replaced and what could be repaired or cleaned to make things work. All in all a great experience. Definitely recommended!"

"Mo called less than 5 minutes after I posted at HomeAdvisor noting that my air conditioning had died, in July. He squeezed me in for the next morning. They've been diligent about replacing parts, found a way to keep me cool during as they're installed. I added some maintenance for my tenant unit and they were there instantly. Couldn't be happier. HomeAdvisor comes through again. And so did Mo."

"We had our old boiler removed and a new 250,000 BTU Weil-McLain installed. The experience was great. The price was really fair, especially for the quality of work. They showed up right on time, got straight to work, and you could tell they knew exactly what they were doing. Everything was done in a very organized and professional way, but still felt easy and stress-free on our end. What I appreciated most was how clean and quick they were—no mess left behind, and the job was done faster than expected without rushing anything. Overall, just solid, reliable service. Would definitely recommend them to anyone needing boiler work."

"Excellent company and excellent service. I would recommend them to anyone who needs a split pack AC unit installed or repaired."

"The installation was professional and efficient."

"Recently, I needed to replace the AC condenser unit, and I turned to Reliable Service NYC. I was very pleased with the quality of the work done. The technician arrived on time, diagnosed the issue, and quickly replaced the faulty unit. All the work was done professionally and neatly. After the replacement, the air conditioner works perfectly, and I can enjoy the cool air in my home again. I have an Irish Setter named Ginger at home, who is usually very cautious with strangers. However, with Grigory, it was different. Ginger immediately showed interest in him and stayed by his side throughout the work. This was surprising, as Ginger rarely warms up to new people so quickly. If my Ginger trusted Grigory, I highly recommend his services to you as well."

"He was responsive and installed the correct thermostat"

"Mario did a great job installing our electric water heater. He was very accommodating. The work was done on time at the price to which we had agreed. He was careful and cleaned up."

"Appointment was scheduled on the same day and they were on time. The employees were friendly and polite. $795 plus tax for a 10 vent system seems quite expensive and out of the range quoted on the website. I called because I had visible mold on the ceiling diffusers. They made an attempt to blow these but it didn't achieve anything so they suggested I replace all the diffusers. I cleaned them myself with bleach. The owner called me to follow up and I told him that I thought the price was a bit high so he offered a free dryer vent service. I thought that was an excellent follow up."

"Jonethan definitely delivered when installing my air conditioner. He was very polite and welcoming. I look forward to using his services again in the future. You won't regret hiring him!"
