"Called Stephen MIchael for an estimate.  He came out the next nite, gave me the estimate and I hired him.  He
came the next nite in the rain exactly at the time advised.  Loaded a hugh truckload of old wood, fencing, etc on the
truck..got it all.   Then he even swept up the driveway in the rain.  Very professional and I was extremely happy.  
Would not hesitate to hire again.   "

"It went well. The new unit generates more than enough heat for that area. Very satisfied with his work. This is the third time I have used WTPI. When I purchased this house the furnace was not working (we knew this), They installed a new furnace and a separate hot water unit, all natural gas. We had a water problem in the cellar, the furnace was ok but the electronic control for the water heater was damaged. They replaced this within hours. Have always had a good experience with this company."

"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."

They sent out contractors on their list. They don?t do the actual work. What they would do is schedule the contractor and then the contractor would not show up and then they would say we thought we called you to tell you they had rescheduled or something like that. The contractors sent the quotes to Top Notch and then Top Notch gave us the quotes. There were a lot of different things to be done. One company they sent out added something to the quote that was not to have been in there. They did not provide the insurance company with the proper paperwork that was necessary

Install Boiler FAQs, answered by experts

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.

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

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.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.
