"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."

Install Boiler FAQs, answered by experts

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
