"Expert installation with the contractor choosing a great mini split unit which surpassed my expectations. Contractor showed respect for the property and left the job site clean and ordered. Would definitely hire the company again."

"Brady and Casey are an awesome team. They came a long distance when the locals couldn't or wouldn't. They're friendly, extremely knowledgeable and if they were closer, they would be our regular furnace experts!"

"I am very happy with how it went. You hire a company to perform the services they advertise, but you recommend a company (and person) based on the quality of the work and how each step of the process went, from initial contact to project completion. Stephen is extremely professional and comes with a great attitude to get the work done. Removing the demo from a plaster and tile bathroom is not white glove type work, which made the time he spent at cleaning up after every step of the process that much more appreciated. Highly recommended and I expect I will be calling on him again in the future."

"Everything was wonderful from start to finish. Norman and his staff were attentive and friendly throughout the whole process. We were given a quote and then took some time to get other quotes and secure financing. When we were finally ready to commit we let WTPI know and they had our furnace installed within a week! A few days later when the system needed to be balanced Norman was out that afternoon to get everything set up. He is very knowledgeable and made the whole process very comfortable and enjoyable. He explained everything very well and even invited us down to check things out every step of the way. I highly recommend WTPI for any job big or small. We will definitely use them again!"

"I had a lot of additional cost. It ended up at $1500. They only cleaned three, for the big deal. And then, I had a thing that they put in to make sure that the air stays clean. They said I had a humidifier on my furnace and they said that it had to come off. And then, they said you can get a much better one and then they kind of disappeared and they didn't talk about it or really sit down and have a conversation with me. I'm not even sure why they had to take it off or what they did."

"Company did a good job last summer with 3 bay windows, so I called them back when the rest of the windows in the house needed to be replaced. On the initial visit, I told the rep that I wanted the same windows as last year. He quickly found the job order and picked up the details of the window make/model/etc without any need for me to reinvent the order. The company had the opportunity to try to upsell me, as I asked them about replacement of the skylight in the bathroom. Refreshingly, they declined to do so and told me that it would be much better to wait until we needed to get the roof re-done, and to do the window at that time. As before, the first guy clearly explained the process: guy 1 to take the order and measure the windows, later follow-up visit from guy 2 to remeasure all the windows carefully before ordering their construction, and then a couple of months later, a follow-up call from their HQ to schedule the install. He gave me an approximate window for this scheduling call. It was a pretty broad time-frame because there had been an unusually large number of people needing custom windows. As before, everything went off exactly as the rep indicated. The install team showed up within a half-hour of the estimated time, and installed 11 windows without taking a break. They removed every scrap of rubbish, vacuumed thoroughly, and left the place as clean as it was when they arrived."

"Once again, NE Renovations did themselves proud! We had a problematic boiler system that was giving us fits for years, but were reluctant to pull the trigger for a new one. Richard and the team found the right boiler for our home's layout and our needs. They installed the boiler, took the other one away, and we barely knew they were there! To top it all off, they even took care of the rebate from National Grid and just took that amount straight off the already very reasonable bottom line! What other firm would do that? These guys are great and I will continue to use them for all kinds of work around our home! Professional service, great quality, reasonable prices, and honesty to the point where I am completely comfortable leaving them in my hone alone! Service as it used to be and as it should be!"

Install Boiler questions, answered by experts

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

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.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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.
