"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"I gave Petro an overall "C" rating because that's halfway between their good score for service and their bad score for prices. I was a Petro customer for approximately 22 years, but I switched to a different company this summer because I could no longer afford Petro's prices. If it weren't for their high prices, I would still be a customer of theirs. IMO, with respect to prices of home heating oil, Petro charges one of the highest per-gallon prices in northern RI. During the past few years I've compared oil prices with friends who bought their oil from other companies, and the prices I paid were always between 60 cents and one dollar higher per gallon than what my friends paid. As a senior on a fixed income, paying a dollar more per gallon is no longer an option for me. I was on automatic delivery for heating oil, and up until a few years ago that was great. However, at least once during each of the past two winters, I had to call for a delivery when the oil level in my tank was almost at the bottom. With respect to having one's boiler serviced by Petro, the service was good, and their technicians were always professional. If you have a service contract, you have the peace of mind knowing you can call them 24/7, no questions asked. But you will pay for the privilege. Overall, my opinion is, if you don't mind paying Petro's prices, you will be very happy using Petro for your home heating needs."

"I could not be more pleased with this company or this service. I found them here on AL and with a rebate, it was a great deal. When I called, the woman who answered was extremely polite and helpful and took the time to go over the entire audit process with me (she wasn't rushed as some receptionists are). They sent an email to confirm the date and time.
When the team arrived, they were on time and each of them introduced themselves by name to me before coming into my house. They were all very polite and courteous. The leader (I can't remember his name) gave me an overview of the process and explained things as they went. Basically, they simulate high winds around the house and then monitor for where leaks are. My house is relatively new and has no basement, so it was already pretty efficient, but there were some major leaks by the front door and attic door, which they sealed on the spot. They also showed me that I could hold my hand over any electrical socket, even ones on interior walls, and feel the "wind"--which means air was leaking out those! So I plugged them all with those little socket protectors. The guys also took me into the attic and showed me some leaks, and fixed them--and fixed the attic door by adding a little latch to help it stay closed. All in all, they reduced the amount of air getting into my house by 500 (I forget the units). It was clear they didn't just make up this number--they showed me the number after the first test and then after the second test (when they had treated the problem areas).
I also got a few free CFLs and LEDs, and bought 3 more LEDs since they were at a great price. They left some rebates with me, although all my appliances are new so I didn't need anything. 
When they left, they each said goodbye and were very professional until the end. They were respectful in my home and asked before opening any closets or doors, etc. I felt very safe with them here, which is not always the case when people are in your home working. I think the price is a fantastic one, especially with the AL rebate that was on when I scheduled. I feel I got my money's worth. My husband and I had tried to plug some leaks ourselves, but we didn't really know what we were doing and we had no way to measure if we were really helping anything. This audit gave me hard numbers to look at and I was impressed that they did the fixes on-site (included in the price--for instance, they plugged a whole around my front door frame by installing a clear plastic barrier). It was a great deal and a great experience. Highly recommend!
Bonus--when we resell this house in a few years, I will definitely list that we got a professional energy audit performed on it and that it's very efficient. Definitely a selling point!

"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.

"Vista Home Improvement was contracted to resurface my decking surface and to install new railings. The company also did
some siding work as well. Overall, I was very pleased with the work and the quality of work.  Brian is very personable and was always willing to answer any and all questions I had.  From the beginning of the job to the very end Brian was extremely helpful and whether it was through phone calls, emails or in-person conversations Brian always answered my questions and concerns and
ensured all my questions were answered. Additionally, the quality of the work was outstanding. I am very much a perfectionist and really strive to have contractors perform work to perfection.  With Vista Home Improvement even my very small concerns were addressed by the company even though for 99%of the population the very small concerns would not have been noticeable.  The employees of Vista Home Improvements were top notch professionals (I mean everyone from Brian to Kim in the office to the
on site employees!!) and they also answered any questions I had during the project.  They were all very professional and did not take short cuts even when the work was going to be covered up.  The employees, including Brian, were always very punctual and very responsive! I strongly recommend this company to anyone looking to have home improvement work performed and I would definitely use this Vista Home Improvement in the future for home improvement work!! In the end the desk and siding work came out fantastic! even the railing on the desk was perfectly installed!  Brian and his crew measured the railing sections to perfection and they fit perfectly!  I have used a good number of contractors in the past to perform a variety of home improvement projects so I can honestly say through quite a bit of experience using home improvement contractors that Vista Home Improvement was the best of all of them!! To Brian, Kim and everyone at Vista Home Improvement please keep up the Great Work!!!

Install Boiler FAQs, answered by experts

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.

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.
