"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Brian and his crew were great. Brian came out and gave a great estimate for everything I needed. He was very responsive via email as we worked to schedule a time for his crew to come do the work, which was mainly water tank and heating system maintenance. Brian brought Jim promptly and explained the work. They then pointed out a couple of things that they recommended replacing, one they just included in the original cost estimate and another they added on due to additional parts being purchased. Jim was very thorough and professional and, by all accounts, did great work. I’ll be using Heavy Doody for all of my future plumbing and heating needs!"

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

Customers say: Super punctual

"The service tech arrived a few minutes after the end of their arrival window. Reception did call to notify a slight delay. No big deal here. We reviewed the steps I took and after some preliminary inspection the tech revisited the system bleed. No air this time. It happens the boiler in question is a Burnham Revolution, notorious for various cryptic failures. We were discussing the inevitable replacement option when he homed in on the primary loop pump motor again and realized it was locked up. It had everyone fooled as it was vibrating as if it was operable, but hot a Hades due to the frozen prop shaft. This gig would probably have summed up @$600 but for the tricky diagnosis and my loquacious tendencies. At least I know who to call when I'm ready for that replacement/expansion."

"I consider myself super lucky to have had Mike install our water heater, and then subsequently a gas boiler with indirect water heater. He truly IS a master plumber, that boiler looked like a piece of art at the end of installation, and it works like a charm! In addition he did quite a bit of plumbing by moving around a second water heater, to save us some room in the basement - free of charge! Not only is he an outstanding and extremely hard working plumber (you can judge from the number of reviews!), but also a deeply decent man of exceptional integrity, truly an inspiration to all of us..."

Install Boiler questions, answered by experts

Costs depend on issue severity, parts needed, and labor rates.

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.

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.

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. 

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
