"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

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.

Deciding whether to repair or replace your HVAC system largely depends on its age, the cost of repairs, and its overall performance. If the system is over a decade old and requires frequent or expensive repairs (e.g., totaling over $5,000), replacement is often the more cost-effective choice, especially if the warranty has expired. It is usually worth repairing a newer system, but if it is approaching the end of its typical 15- to 25-year lifespan, replacement might be a better long-term investment. Signs that you may need a replacement include increased humidity, higher energy bills, uneven heating or cooling, and excessive dust. Before deciding, ask your HVAC contractor to check if any parts are covered under warranty, which could save you money on repairs.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.
