"Dave (Dawson Mechanical) is awesome. He is the only plumbing company I use. His knowledge is on another level and he runs a great company. It is easy to get an appointment and he responds right away. You can feel confident, if you have an emergency or non-emergency situation you that can get touch with him. In the past he installed a new boiler, furnace and converted us over to gas from oil heat. The work he and the guys did on the furnace/boiler is so good that other contractors comment on it. It really is a work of art - very neat. Most recently, he helped fix a bad plumbing job a contractor did during a bathroom model. The bottom of the toilet was flooding and the shower made a gurgling noise every time the toilet was flushed - it was an annoying odd problem. John came over during the covid pandemic, analyzed the situation and came up with a solution. He wore gloves, a mask and maintained space between us. I am very impressed with his expertise and the level of detail and attention he works with. However, I shouldn’t have been surprised based on how great of a company Dawson Mechanical is. He hires quality technicians. Lesson learned - dont let the contractor do plumbing work. I will definitely use Dawson Mechanical again."

"Very satisfied with their service and workmanship. Our boiler stopped working 3 days before Christmas and we had a houseful of guests. Brian diagnosed our issue quickly and work hard to find the replacement parts we needed. All good now."

"Tom did an incredible job. We had no heat and no hot water with freezing temperatures outside. We were told by other companies that the boiler was beyond repair and had quotes from $16,000-$21,000. When I told Tom I was told the boiler could not be repaired, he insisted on seeing it for his own evaluation. He came in on a weekend and fixed it for a completely reasonable and affordable price, saving us over $15,000! Best of all our heat and hot water are both back and the house is once again warm and toasty! We are saving his number and will hire him again without hesitation. He is honest, reliable and trustworthy."

"I had such a great experience with Liv Air! They serviced my boiler, and from start to finish the process was seamless. Leo is incredibly professional, easy to speak with, and genuinely such a nice person. He?s honest, reliable, and you can tell he truly cares about his customers. The technician who came to replace the parts was also wonderful ? very clean, respectful, and efficient. I?ve dealt with other companies before, but no one even comes close to the level of service Liv Air provides. Their pricing is fair and reasonable, and they answer calls right away, which is so rare these days. I?m honestly taken back by how great they were. I highly recommend Liv Air!"

"Zach from PipeWorks came today to install a new kitchen faucet and do an annual clean/diagnostic of the basement boiler. In both cases, he discovered and patiently explained upgrades and replacements, which he performed expertly. He also answered all of my questions with care â including the dumb ones â and explained the charges clearly. Zach didnâ t try to upsell me anything unnecessary â he did what he needed to do and didnâ t do what he didnâ t need to do. Finally, heâ s a very nice and polite guy, which made the event comfortable and trustworthy. Iâ m thrilled with my upgraded faucet, which works perfectly, and glad to have the boiler in tip-top shape for the season. I happily recommend Zach and PipeWorks to be your in-home experts for fixes and recommendations."

Install Boiler questions, answered by experts

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
