"Service technician was very professional. He took time to show me what had to be fixed and explained how it would improve furnace performance. He took the time to make certain I was satisfied with the outcome. He tested the systems to check they were in good working order. Finally we have excellent customer service."

"Response time was incredible fast and a service appt was scheduled that was early and convenient for my husband to be present. Donnie and John texted their arrival time. They were prompt and professional. They accessed the furnace and located the problem. Within a few hours problem solved, and house was warming. I highly recommend this service."

"These guys were amazing. They were the first ones to call after I submitted a request on Angie's List, and they came out the same afternoon. They did everything they could to keep the price of the repair down, including calling the furnace manufacturer to see if some of the parts were covered by warranty. Then they were willing to work with me when it ended up costing a bit more than I expected (something that was out of their control.) They lent me a few heaters to put in my kids' rooms overnight since the parts place had closed for the day by the time they knew what they needed. The level of care I received from this company was incredible - not something I expected at all. I'm really happy to have worked with them, and I most definitely will be giving them my business in the future!"

Install Boiler FAQs, answered by experts

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

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.

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