"EXCELLENT. Needed this done ASAP with cold weather (and while we were out of town). Keith was super responsive - I trusted him with this install and defining the right equipment for us. VERY knowledgeable!! Team did GREAT work. Were super responsive to the one small complaint I had (didn't fill small hole in outside wall where AC piping went in, bummer for mice entry....). They offered to fix right away, but I had already. So far, very happy with American furnace that was installed!! Easy master controller to operate. Keith came over and reviewed equipment, install and operation as well as optimization points with us. VERY useful!!!!"

"We were pleased to work with Greg Mair who came to.our house the night of Jan17, 2024 after our 14 year old furnace died. He reviewed our entire system and made recommendations that fit our needs correctly. He arranged for a new furnace to be installed the next day and provided us with space heaters to be used until the work was completed. We will definitely call on Greg for any future needs."

"We called Eli when our old humidifier started leaking. He came out that day to take a look and recommended a new unit to replace it since it was 22 years old. He returned a few days later and installed the Aprilaire unit and it works like a dream. I would recommend Eli for all of your heating and air repairs."

Install Boiler questions, answered by experts

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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.

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.
