"They came out within 24 hours and I appreciated their promptness. They didn't charge me anything to come out and their quote seemed very reasonable for what they were asking. What stood out to me more than anything else was that they weren't stuck on any one brand of furnace or A/C unit. They marketed a wide variety of different brands and they picked the one that was the best to fit my needs. They found the best furnace for the size, the best efficiency, and the best cost. They're not getting a commission by pushing a particular brand like a lot of the others are. I think they could've done a tiny bit better on their pricing, but other than that the experience with them turned out to be was real enjoyable."

"When my computer refused to boot up, I took it to Jim and he diagnosed a virus infection as the problem. He got the machine working again by installing a new hard drive and adding more memory for increased performance. Just a couple of weeks later, the computer again was having problems. This time, Jim dianosed the culprit as being the machine's original memory. While I decided not to remove and not replace the faulty memory for the time being due to cost, Jim upgraded my operating system to enhance the overall system performance. Jim was very professional and timely and was very sensitive to my concerns. Communication is excellent."

"Jody did a great job and was very professional.  My only complaint is the price seemed a bit excessive.  I did receive a discount using an internet coupon, so that did help some. Considering it was less than 1 hour of work and the cost of the part was probably less than $200, I would not expect labor costs to be so high.  Typically I will not use a company who I feel overcharges, but I really had little choice this time.  I understand it was after hours when the work was performed, but I requested service during normal hours.  Unfortunately they were backed up with service calls, so it was 8:30 PM before he was able to arrive.
I am grateful that I was able to get the pump replaced.  I just wished it was not so expensive.  I fully support our local businesses and that's why I use them.  However, sometimes they make it hard to come back for services.  If I had an option, I probably would have shopped around more before choosing a company.  This was a crisis, so no time to research and schedule an appointment.

Install Boiler questions, answered by experts

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

Costs depend on issue severity, parts needed, and labor rates.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
