"Tom did an incredible job. We had no heat and no hot water with freezing temperatures outside. We were told by other companies that the boiler was beyond repair and had quotes from $16,000-$21,000. When I told Tom I was told the boiler could not be repaired, he insisted on seeing it for his own evaluation. He came in on a weekend and fixed it for a completely reasonable and affordable price, saving us over $15,000! Best of all our heat and hot water are both back and the house is once again warm and toasty! We are saving his number and will hire him again without hesitation. He is honest, reliable and trustworthy."

"I called in the late morning and the friendly office person took down all my information and gave me a window of time between 2-4 PM. She later called and said that the serviceman got done early with his morning job and would like to know if he can come earlier. The repairman, Andrew, was professional and knowledgeable. He opened the heating system access doors and found an error code. He promptly fixed the issue and also cleaned another part, which he said could give problems in the future. He took the time to explain why the problem occurred and what he did to fix it. He also took down the make/model of the heating system in case it needs more work in the future. Since there were not parts required, I was only charged the minimum service fee. The heat is working solidly now."

"We have been very pleased to use Raynor Services for installing new outlets in our home as well as yearly service to our heating system and electrical inspection of our electrical systems. Bob E. just left after inspecting our electric and offering some options for projects we plan next spring. The attention to customer satisfaction from Raynor has been exemplary. We can always reach a live polite person by phone, receive immediate attention, and on-time respectful technicians that clean up after they are done working. Bob E. was professional and yet cheerful and friendly in explaining options and costs to me this morning. Who could ask for anything more? We do pay $19 per month to insure our HVAC and electrical systems are safe and effective. Raynor is our trusted "go-to" company."

Install Boiler FAQs, answered by experts

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

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.
