"Joe responded right away and was on time for the quote and installation. The central AC was done in half a day and he and his partner cleaned up after the work was done. In addition, his cost beat Jeff Lowe's Plumbing and Heating cost by over $2,000 on a comparable unit. AC works great. No complaints."

"The service he gave me was phenomenal. Willing to work with you at all cost. Especially on a day like this, On a ice Strom, he offered to come to my house in the middle of the night to shut off my water heater, he meet me at home depot and told me exactly what I need. He brought the water heater down to my basement, installed and removed the old water heater. Left no residue from the other water heater. I was just Amaze with his help since I'm single parent. Once again Thank you Mr.Crandall"

Install Boiler FAQs, answered by experts

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 want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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.
