"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."

"David and his crew were great! They were very communicative on what the issue was and responsive to my questions and calls. I had a pipe dug out and replaced in my yard by then. Will definitely hire them again if anything else happens. Would highly recommend to anyone looking for work done correctly."

Customers say: Quality work

"David Kappas was very responsive-- he called me on Monday and we set an appointment for Wednesday. Tuesday he called me to tsay that he would be arrive at 11am instead of 9am as he needed to finish up some work. He fixed my clogged faucet and installed a shut off valve in an effective, efficient, calm manner. I went over some other plumbing needs and he discussed each one in a sensible way. I'm planning to use him for the other plumbing projects and am awaiting his estimate."

"I selected Polar Plumbing because of the many positive reviews on Home Adviser. I was not disappointed. My ultimate selection of Polar as our vendor of choice was based on their total solution proposal to our heating and water issues. The primary interfaces were Ray and Jared. Ray was the communication link to the project and kept us informed throughout the process. Jared was the front man. His plumbing, heating and water treatment expertise was clearly evident. The project began shortly thereafter and the team was precisely on time and very professional. The oil fired boiler was installed the first day and the old oil burner and associated equipment were disposed of. The installation looked and performed great. The next day was the installation of a water treatment system, 2 Nest thermostats and baseboard covers. In two days our lives changed: reliable consistent heat and hot water, and the odorous sulfur smell was gone. Kudos to the Polar team."

Install Boiler questions, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

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.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
