"In October 2020, I had a gas leak and I did not even know it until I was doing annual maintenance. The first company that came out made me believe that it could not be repaired and did nothing to mitigate the issue. I thought I would have to figure out where I was going find about $10 to $20 K to replace my boilers. I could not afford that. I called Sync Mechanical for a second look. They gave me an honest diagnosis of the issue and told me where the gas leak was as well. They told me that it is repairable and laid out what my options if I wanted to do repairs or replace it and the cost as well. They talked to me about their financing options at the time. I really had options. This gave me peace of mind because the gas leak was much smaller than I was made to believe before, but Sync Mechanical took the leak seriously. They identified other parts of my boilers that needed to be replaced to avoid pipes bursting such as my expansion tanks and pressure relief valves. I agreed to get the repairs made. Sync Mechanical ordered the parts, kept me updated on the arrival time, and called me when they arrived so I can schedule a time. Sync Mechanical was also honest about their schedule when also responding to emergency calls of no hot water. I appreciated that because I was never left with false expectations. They were able to fit me into schedule even when it was very busy. It felt great going with a local professional company that were honest at every step of the way and large enough to handle multiple jobs in the Hudson Valley. I did not feel overlooked. I have been stood up by contractors twice before so it was really important to me that my time was not being wasted. The repairs were done within a day and all the old materials were disposed of by Sync Mechanical. I also received my invoice in the mail which made it easy for doing my taxes. Sync Mechanical helped me make an informed decision and also learn more about how my boilers work. I never felt like they were condescending and I appreciated their respect for family as well."

"Moved heavy boiler up difficult site. Installed in one day. Very professional and patient in detailed explanations of complex zoning issues. Prices are high in Dutchess Co. compared to other areas of NY. I generally think plumbers are a safer bet for a maintenance plan and longer lasting businesses than most HVAC companies."

Boiler Repair questions, answered by experts

Yes, it is generally safe and effective to turn off radiators in unused rooms to save money on heating costs. This practice is especially beneficial with older heating systems. However, you should avoid cranking up the thermostats on the remaining radiators to compensate, as this can lead to higher heating bills and increased wear and tear on your system. While some HVAC specialists argue that modern, efficient boilers are designed to heat the entire home and work best when all radiators are on, turning off radiators in unused spaces still reduces the total amount of hot water your system needs to produce.

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.
