"We hired Loudon Mechanical to install Daikin mini-splits in our home. The quote was reasonable. Each person in their crew was courteous, prompt, and efficient. They completed our job in two days and left the job site clean. W are extremely pleased with Loudon Mechanical and would highly recommend this company."

"I bought a really nice regency gas fireplace from South Shore Fireplace and couldn't have been happier with the way they treated me and completed the installation. They were the most attentive and considerate companies I approached which is why I went with them. We couldn't get the time of day from other fireplace stores. These guys were right on the ball from the start. Spent a lot of time going over the different stoves and options that go with them all. The installation was scheduled and went very well. Installers were very thorough and clean. This was a complete installation, needed the chimney as well as the stove. Everything was done perfectly and I couldn't be happier. Recently, the stove I picked had a recall and I was informed and updated by Scott as soon as he had news. This actually went on for a couple of months but Scott would contact me every couple of weeks and let me know what was going on. When the replacement part came in, they scheduled the work IMMEDIATELY and I met Jon, one of the senior techs and installers. Jon was on time, meticulous and thorough. Very clean and organized as you would expect a master craftsman to be. The repair went very well and made my stove run better than ever before. When your happy with a job someone does for you, you hardly ever write a review but something turns sour, people can't write one quick enough. When I need something done, I go online and read all the awful reviews of probably great companies so I do not hire them. This review is for all of you that are like me and come here to get the low down on a business. Do not hesitate to go with South Shore Fireplace. It is very hard to find craftsman who really care about what they do and also so nice to deal with. South Shore Fireplace will be my go to guys for the rest of my life. Love you guys - job well done and sincere thank you for your continued support throughout the years."

Install Boiler FAQs, answered by experts

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

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.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
