"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"The salesman was knowledgeable and thorough. I did significant research and went with Carrier. I believe I received a fair price on excellent equipment. The installer arrived promptly at 7:00am as promised. He was cordial and clearly knew what he was doing. I was very happy with them and would recommend them."

"I cannot say enough wonderful things about this amazing company! My daughter and I had been without a furnace for over 6 years. We used space heaters in the bedrooms, bathroom and kitchen, but the rest of the house stayed cold. Along with that, I had a constant fear of an electrical fire resulting from the units, because last year a young mother and her baby died in a house fire down the street from us, most likely caused from a space heater. When Schraer came to our home that offered to install gas furnace free off charge that was just sitting in their shop! We are truly Blessed and Grateful for their kindness and generosity! There are good people out there in the world, and the owners and employees of Schraer Heating and Cooling are some of best!"

Install Boiler FAQs, answered by experts

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

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.
