"Very glad I did it. I need a new furnace. There's a lot wrong with it. Found out it's almost 15 years old and could die during winter. The tech will get me prices on different ones and will go from there."

"During the massive December 2022 blizzard in Western New York, my house lost power for three consecutive days. I'd just switched to an all electric HVAC system weeks before, and none of it was connected to the small electrical panel that my gas generator could power. We were facing no heat, in a blizzard, for three days. I called Connor who, despite the weather conditions, came out to the house that evening. He opened my generator panel and rewired it so it would get heat to my kids' rooms. Without asking, he then found a great price on a Generac whole house generator and passed the information along to me. Long story short, I hired Enchanted Mountain to purchase and install the generator. They did that and more. My family now has no worries when the next blizzard hits. The care, knowledge, and attention to detail that go into Enchanted Mountain work are unmatched. I've since hired them for everything from roof repairs to insulation and weatherization jobs. They can do it all, and you won't find a nicer, more helpful and caring crew anywhere in the region. Hire them once, and, like me, you'll plan to hire them for life."

"The guys were great, very professional and friendly. They came to inspect the basement area before the installation to make sure they would have everything they needed to do the job. When they came back to do the furnace installation it was done quickly and effectively. We love the new furnace and are toasty warm!"

Install Boiler FAQs, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

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.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
