"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"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."

"Andre arrived on time prepared to service my Navien combination boiler and domestic hot water. He was knowledgeable and completed the service more thoroughly than others in the past. His pricing was as discussed. I recommend Andre to do this type of work for others."

Install Boiler FAQs, answered by experts

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.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
