"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.

"Hired the Comfort Company to install a new propane high efficiency furnace, air source heat pump and take out my old nasty oil tank. Very satisfied and my wallet took a smaller hit than I thought it would! Highly recommend!"

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

"The team arrived on time, and worked with Home Depot's man putting in the water heater. Everything was explained, put in, cleaned up in a timely manner. I was extremely pleased with their work."

Install Boiler FAQs, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

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).

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.
