"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

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.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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.
