Energy Efficient, Clean Air & Radiant Heat: The Power of Water
For homes with hot water heating systems, Preferred Air installs and maintains highly efficient boilers. We repair and service all major makes and models — and provide 24-hour emergency service.
What is a Boiler Heating System?
Boiler heating systems have two parts: a boiler that heats and delivers the hot water, and a network of pipes that carries the water through the rooms. The pipes are typically installed in the subflooring, but can also be installed in baseboard heaters and radiators. The hot water evenly radiates heat throughout the room, providing comfortable, high quality heat.
Benefits of a Boiler Heating System
Installation
Preferred Air offers condensing boilers that provide the most efficient, environmentally friendly form of heating for hot water baseboard and radiant systems. Thanks to low fuel consumption and lower heating costs, our customers sometimes find that a new boiler can pay for itself in only two to five years.
Service
A well-maintained, good quality boiler can last for decades if it receives regular inspections and servicing. For boiler service, our techs have seen a wide array of boilers of all makes, of all ages, and of all conditions. We will ensure that the repair will be done right — the first time. We’ll do everything possible to provide same-day service, especially in no-heat situations.
Don’t wait until your boiler dies on a freezing winter night. Call us for a no-obligation consultation of your home or business. Contact us to get your questions answered about boiler installation and service. 978-750-8282

At Preferred Air, we believe that maintaining the system that works for you is the best option. That being said, if your furnace is over ten years old, a replacement may be worth considering. Within the past ten years furnaces have improved in efficiency, and replacing an old furnace can save a homeowner up to 50% in heating bills.
Types of Furnaces
How it Works
Although there are different types of furnaces, they generally work by first heating air and then utilizing ductwork to circulate it through your home. Efficiency of a furnace is measured by how much fuel the furnace converts into heat during a year. This is called the annual fuel utilization efficiency or AFUE.
In the 1990s and earlier, furnaces had a 65% or less AFUE. This means that 65 percent of the fuel was converted into heat, while the other 35 percent was lost. Today’s furnaces have a 80% or higher AFUE. This efficiency means the unit uses less fuel and produces less pollution, resulting in a lower cost for you.
