"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

"Phil came out to provide a free estimate for a new boiler. Appointment was scheduled for the same week and Phil called to move up the appointment due to a cancellation. He was very thorough, asked questions and answered all of mine. Would definitely recommend.

"Dan was incredibly helpful every step of the way. He broke our estimate down for us, separating the cost to just replace the boiler and to add a radiator to one of our rooms. He also had a plan to be able to do the projects separately, if we wanted. We ended up doing everything together. It was very quick, the techs were super polite and knowledgeable. Would HIGHLY recommend."

Install Boiler questions, 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.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

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.
