Expert Boiler Installation & Replacement

A properly installed boiler is the foundation of a dependable hydronic heating system. At Tandem Mechanical, we handle the full scope of boiler installation and replacement — from sizing and equipment selection through piping, controls, venting, and startup. Whether you're replacing a failed cast-iron boiler, upgrading to a high-efficiency condensing unit, or installing a new system in a renovation or addition, our licensed technicians follow all applicable Massachusetts and Connecticut mechanical codes and manufacturer specifications. We work with hot water (hydronic) and steam boiler systems in both residential and light commercial applications, and we take the time to properly commission every installation so your system performs as designed from day one.

Repair vs. Replacement

A boiler repair makes sense when the unit is less than 10–12 years old, the heat exchanger is intact, and the repair cost is a reasonable fraction of replacement cost. However, once a boiler exceeds 15–20 years of age, shows signs of heat exchanger failure or significant corrosion, requires repeated repairs, or operates below 80% AFUE on a fuel-intensive system, replacement is almost always the more economical long-term decision. Condensing boilers operating at 90–95%+ AFUE can dramatically reduce annual fuel costs, often shortening the payback period on a new installation. Tandem Mechanical will give you an honest assessment of your existing equipment so you can make an informed decision.

HVAC Maintenance

Annual maintenance is essential for keeping a boiler system safe, efficient, and code-compliant. A proper boiler tune-up includes cleaning the burner and heat exchanger surfaces, performing a combustion analysis to verify proper air-to-fuel ratio, inspecting the flue and venting for obstructions or deterioration, testing the pressure relief valve and low-water cutoff, checking expansion tank pressure, and inspecting all controls and safety devices. For oil-fired systems, annual service should also include nozzle and filter replacement. Keeping up with maintenance extends equipment life, preserves manufacturer warranties, and reduces the risk of mid-winter failures.

System Performance

The efficiency and longevity of a boiler installation depend heavily on factors beyond the boiler itself. Proper hydraulic separation between the boiler loop and distribution system, correctly sized circulator pumps, adequate expansion tank pre-charge, and appropriate system water treatment all play critical roles. Condensing boilers in particular require low return water temperatures — typically below 130°F — to achieve their rated efficiency, which means the distribution system design must be compatible. Tandem Mechanical evaluates these factors on every installation to ensure your new boiler delivers its full rated performance throughout its service life.

What Customers Say About Our Boiler Replacement & Installation

Google

“I am a first time home buyer and not familiar with the boiler/heating system in my home and was apprehensive about finding a service provider to service my boiler. I def. made the right choice choosing Tandem Mechanical to service my boiler system. I needed my boiler serviced and Josh and Sam arrived today and serviced the boiler in a professional manner. Josh explained everything they were going to do before they started work. They were punctual, professional and went above and beyond. They also addressed questions I had on two other issues, one which could have been a problem later on if not addressed. I was very impressed with these guys and also the lady I spoke with re: setting up the appointment. Thank you TM! Much appreciated.”
