"Very glad I did it. I need a new furnace. There's a lot wrong with it. Found out it's almost 15 years old and could die during winter. The tech will get me prices on different ones and will go from there."

"Bassett was fast to respond to my inquiry on Home Advisor/Angi. They offered to evaluate my old boiler furnace that evening so we didn't have to miss work to be there. I though we may need a new furnace but they were able to make some adjustments to make our upstairs heat work that night (which it hadn't for a while). They made a plan to return in less than 48 hours with the supplies and equipment needed for a permanent fix. They stayed within the price quote and even moved my thermostat as a last minute request."

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"He came in inspected the area, made suggestions on hot water heater replacements. Left to get the replacement, returned quickly, and installed unit with additional upgrades, plus offered and completed additional work to reduce the chance of having flooding problems damage my heater in the future! Great guy! He’s on my “go to guy” for any future issues in my 1850 home!"

Install Boiler FAQs, answered by experts

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.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.
