"I have nothing but praises to sing for this company! Our heat stopped working on us last week right before the temp was expected to drop significantly. I checked Angie's List, found Air Temp Solutions, submitted my issue and within minutes I received a phone call to set my appointment. They sent over Rob Teixeira who was EXCELLENT!!!! He immediately detected the issue which was the flame sensor, fixed it and viola...we had heat again in no time! We are planning on doing further work with this company as we need to have an additional return grille installed. If you need fast and reliable heating or AC this company (and Rob) is who you should go with...you will not be disappointed!!!"

"After installing a new water heater, my husband discovered a backdraft issue with the chimney. He called Chadds Ford Chimney Sweep on a Friday, discussed his findings with them, received a likely estimate for that work over the phone, and was able to get an appt for Monday morning. Shortly before the scheduled appt, we received a call from them, apologizing for running late, offering the choice of a new arrival time or a reschedule. We were fine with them arriving later in the day. When they arrived, they went right to work, inspecting the chimney inside and out. They swept it, and explained we had a larger issue. Seems our chimney isn't lined. They gave us a price point for getting that work done (ranging from $2,500 for lining to $4,000 if a rebuild was necessary). I loved how they didn't try to press or bully us into having that work done immediately! They wrote everything down on the statement so we can follow up when we are ready. We would defnitely recommend them, and will be using them for all additional work, including vent cleanings."

Install Boiler FAQs, answered by experts

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.
