"Damien arrived on time and determined our issue quickly and corrected our clogged pipes. We also asked him to check out another issue. He stayed and fixed this issue as well. He also cleaned everything up before leaving. A true professional. We will definitely be hiring him again and recommending him to all of our friends. Thanks again Damien"

"I am absolutely thrilled with Domination's Service.  A highly skilled plumber (today Tristen) comes quickly, determines exactly what the problem is, recommends the best products to solve the problem, then the service manager calls with pricing so there are no surprises, and Tristen does an excellent job of fixing the problem and installing new products.  I have had this company come a couple of times and I am always completely satisfied with the excellent work they do.  I highly recommend Domination."

"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."

"Jason and Noah did a great job replacing the old knob and tube wiring and installing a three-way switch on a dark flight of stairs. They worked on our project from start to finish, without interruption, which we greatly appreciated. They did a good job patching the holes they had to make in walls and ceilings in order to run the new wires. They cleaned up nicely at the end of each day and stored their tools out of the way in our basement overnight. At the end of each day, Jason gave us a walk-through of the progress he and Noah had made during the day. He had a positive, professional, "can-do" approach to the work and challenges of the project."

Install Boiler FAQs, answered by experts

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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

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.

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.
