"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 FAQs, answered by experts

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.
