"Very prefessional and thorough. Left my place clean after the install, and even loaned me some goo-be-gone from their toolbox for a project that I was working on while they were installing my furnace. They reviewed what they did at the end, and gave me a card so that I could call with any issues. Would highly recommend Sears and their contractors."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

Install Boiler questions, answered by experts

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.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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.

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.
