"Fantastic contractor. Scott came to my house to provide estimate for furnace installation. Except for the fact that I decided on different approach, Scott would have been my #1 choice. He was over-the-top thorough and comprehensive in inpecting oil furnace, provided detailed and comprehensive information on options, was honest and candid in his assessment. Told me what was necessary and what was optional, not trying to sell me on what he wanted to sell. He also had excellent pricing. Bottomline, he is one of the best contractors I've ever met."

"Needed to replace a 40 year old gas boiler. JP had the best price for a high efficiency compared to 3 other quotes. Jim (owner) was in and out of the project but sensed he was on top of it. He was even able to save us a bunch of space by repositioning the boiler location. Definitely going to use these guys for my HVAC and plumbing needs going forward."

"Both Tara and Robert have been very professional and courteous from the time of the first call till the end. Robert gave extra attention to my specific water heater needs and came back a second time to install and remove a recirculation pump. Also fixed a minor leak on a Sunday. I have recommended to have them add to my HOA preferred vendor list."

"Install action went fine but after the installer left we had problems with water pressure. It turned out that the manufacturer installed tubes in the heater where the water goes in and comes out restricting the flow. The technician found this and once removed we had our water pressure back. Although it took two days to resolve, the technician stayed on top of it and made sure the heater worked to our satisfaction.

Install Boiler questions, answered by experts

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.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.
