"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."

"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.

"House was built in 1890, 2800 SF, 3 bed room 2 bath and heating and cooling it was a struggle. I had enough, enough of wasting my money on fuel(350 gallons + a month), pellets (2 pellet stoves), and trying to keep the thermostat set on 78-80 degrees in hopes it would be 64 degrees upstairs where my kids, and newborn sleep. I entered all my information into Home Advisor(Angi) and I found Mark Reed and his company on this website. I then read all the reviews this company had, then read the reviews on the other companies the website recommended. I found that Mark and his crew were best suited for the undertaking that was about to take place in my home. Mark and his son Gary met me at my house within a couple days and we spent 3 hours walking my home, studying the problems and climbing in the attic. I received a quote from Mark in person and I asked them to start as soon as possible. The crew was great, kept a clean work space and understanding about all my concerns of them working in the house at the same time my family and I were living there. The project took over 2 weeks to complete, and as the project was nearing the end I could feel the changes almost immediately. I could walk up the stairs and it was the same temp though out the house, even though it was 20 degrees outside. All my thermal barriers were met, and exceeded. Out with all the old insulation(and much more), and in with all new blown-in -R60! The crew exceeded my expectations, and Mark was there on and off checking in. While I was at work, I received pictures and updates throughout the day and the communication was nice. Even with the crews in my house working for the month of February I burned over 90 less gallons of fuel at month. That was with over a week and half of no insulation in the attic at all, holes in my walls, a hole in my gable end for access, crew guys in and out all day, and outside temperatures between 12*-31* degrees. I would contract with The Climate Chief again. I hope this helps the next person looking to save money long term, and I hope everyone has the same blessed experience that my family and I had as well."

"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."

Install Boiler FAQs, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

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).

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
