"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"I'm a deep value oriented consumer and this guy is one of the best contractors I've come across for the money. Why would you want to pay for the administrative and marketing costs which comes with the fees charged by the big box guys. D-Day is a true professional and a master craftsman at his work. I've hired him to replace a water heater, install a dishwasher and washing machine, as well as miscellaneous plumbing repairs with exemplary results. I wouldn't even consider looking elsewhere."

Customers say: Super punctual

"As part of a second floor renovation, I needed some new baseboard heaters installed in two bedroom, a pipe connecting them relocated/replaced, and some leaky valves replaced on my boiler. Milltown was one of the only plumbing companies that actually returned my calls, and they were able to come out right away, which was great because it was almost October and was starting to get cold. They did an excellent job with all of the work, and I think the price was reasonable for what they did. They were punctual, clean, and professional. No complaints."

"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."

Install Boiler FAQs, answered by experts

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

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.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
