"This company was excellent all the way around. The staff member who contacted me was very nice and helpful. They were able to come out the same day (I did not have heat). They sent me a text message with a picture of the technician which I thought was an excellent feature. The technician, Jeff, was very nice and extremely knowledgeable. I would definitely hire them again because the work was top quality and the cost was fair and reasonable."

His installation crew was very professional thorough and courteous. I’m very happy with my decision and the completed project."

"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!"

"American Appliance Service was wonderful - extremely responsive, communicative, on-time, polite, knowledgeable, etc. Highly recommend. Our serviceman was Vic (I think he's the owner) and he installed a new ice maker in our Samsung refrigerator and installed a new lower heating element in our KitchenAid oven."

Install Boiler FAQs, answered by experts

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
