"Paul is highly professional and does excellent work. Our old system just wasn’t performing as it should. Paul arrived promptly, worked extremely hard all day long, resolved all problem areas, installing an efficient and wonderful brand new system that now cools our home like never before! He was extremely attentive to our concerns and was also courteous and neat as he worked throughout the day. Paul also followed up with us several times to make certain all was well and we were happy. It is rare to find a contractor who provides top notch service/work and truly takes pride in his work. He is awesome. Would highly recommend ! So glad we found him!"

"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 questions, answered by experts

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.
