"Excellent response. Pipe disconnect found immediately. Just needed gluing. The technician quickly explained and stated cost would be $89.00. I was SO relieved and happy. This company (unlike last one used which Angie's List rated as #1) included dispatch fee in price since repair was done during 1st visit. No hidden costs. No lies @ discounts."

"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."

"Their price is reasonable.  I can usually get an appointment fairly quickly.  They usually do what needs to be done.  They tend to explain to me what is going on with the car and why I might need something or not need something.  They seem to be knowledgeable about most cars.  They don’t keep the car for too long."

Install Boiler FAQs, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.
