"Abel Air came to the rescue! Doug was a godsend for us on one of the coldest days of the winter. He replaced our boiler in a timely manner and did so within the quoted price he first gave us. There was some wrinkles and additional work he did not expect, but he did it all for the same price he initially quoted. Doug and his team are thorough, communicative and completely professional. I would recommend Abel Air for all your HVAC needs. Doug is also one of the nicest guys we have encountered to do work on our home."

"They came out and gave an estimate for a new boiler and we contracted with them for the replacement. The technicians seemed very knowledgeable and thorough. We had a few issues after the installation with air getting in the line and blocking the flow of hot water. However, Our installation came with a 1 year service contract and they returned to remedy the problem promptly and professionally. Bell stands behind their work. We would recommend Bell and will use them in the future."

"The tech arrived promptly, introduced himself and donned paper boots before entering our home. After installing a new control panel and two new Honeywell T6 Pro thermostats, he walked us through steps to download the app and connect to the thermostats. He explained each detail and answered all our questions. He was a seasoned professional from start to finish. John Viggiano provided the initial quote and inspected the job beforehand to ensure everything we needed and offered a very reasonable price. We will be using Perfect Air Solutions for all of our future cooling or heating services."

Install Boiler FAQs, answered by experts

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
