"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."

"The service technician Victor arrived on time and politely introduced himself. Prior to commencing work he inspected the work area (installation and clearances etc). He explained the house heating would be off as he cleaned filters etc. After cleaning/adjustment/testing was conducted, he went over the test results printout with me. All good and nothing required further work."

"Steve and his team are real pros. Jason came out and talked us through the various install options, with a lot more thought and consultation than the other two contractors we talked to. In the end, the quote was higher, but we felt we were getting a better product, backed by a better company. Steve (the owner), Travis and Mike (installers) were pros too. Keeping us up to date, starting/completing the work on time, etc. The crew were super clean throughout the project. They even hooked up everything and reprogrammed my ecobee3 smart connected thermostats. Jason spent an hour on the phone with me about the unit and i know any of them would stop by if we needed more help. We were worried about what we heard about the noise factor with high velocity units and these guys take great care to design the lengths and add sound-dampening material to the last 3 feet of the vents. The whole system is super impressive. Couldn't recommend them highly enough."

"They came when scheduled, did very careful job, attentive to details. The office scheduled the required plumbing and electrical inspections by my town (for new boiler) and that was efficiently handled too. The salesman who made the initial presentation was very informative and measured home carefully before making his recommondation. Very pleased with Heritage."

Install Boiler FAQs, answered by experts

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

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

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.
