"Purchased the deal in the evening on Friday Feb 12, 2016. At time of purchase I advised vendor that best way to reach me is by email or Angie's messaging. Also provided two possible dates in March for the work. Winston responded the next day via Angie's message, and we set up the service date for my  next weekday off, March 2. And I sent him some pictures of the plumbing and street valve. Could not get a commitment on an arrival time, but he called me that morning and advised he had a 9am dentist appointment, and would arrive after that. Showed up with his helper about 1.5 hours later. We could not get the street valve cover off, and thought it belonged to the city, so I made arrangements for Winston to come back today, March 15.
I called the city water dept, and they sent someone over, he said it was not their valve, it was mine and he couldn't touch it, I guess each city is different?.
Anyway, I got the cover off with the help of a saw, a big hammer and a pipe wrench in time for Winston to come back today. We communicated via Angie's messaging in the meantime. Still could not get commitment to arrival time, although I asked for 8am.
Called Winston at 8:15 this morning and he said he would be her by 9:15, arrived at  9:00. We could not get the street valve closed, it was stuck. Not surprised, as it has not been accessed in at least 30 years!. We decided he would put the new valve just downstream of my existing shutoff, and from now on, will not use the old one to prevent further leaks thru the valve stem packing. I also asked him to rebuild the hose bib in the garage adjacent to the main valve, and install heat tape on the pipe before wrapping it (I already had the heat tape, just never got around to installing it. When attempting to replace the washer in the hose bib, the retaining screw broke, so he installed a new hose bib into the old valve body for me. Although I was willing, Winston did not charge extra for the extra trip and the extras I asked him to do.
Overall, I am more than satisfied with this experience. My only complaint is not getting an advance commitment on arrival times. But once I did get a time, he was punctual, even early. Would give an A- on responsiveness if I could. But overall, an A experience!
Will definitely use A REAL PLUMBER again. In fact, we already discussed installing a freeze-proof valve for my backyard hose bib.

"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."

Install Boiler FAQs, answered by experts

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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.

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.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

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.
