"My boiler in Wolfeboro NH failed suddenly. It was old and needed to be replaced anyway but I was hoping to get another season out of it. I called quite a few boiler companies and had difficulty even getting someone to answer the phone. Then I lucked out. I called Ed Grant and he answered his phone. It was November and getting cold. He came out to the house promptly and very professionally installed my new boiler. Not only is this guy honest, straight forward but he is such a hard worker. He worked diligently until the job was up and done. Absolutely no headaches, no bullshit, and not a salesman whatsoever. Ed Grant is the REAL deal if you need a new heating system. I would hire him again in an instant without a worry. A+. Thanks, Ed Brian Whitehouse"

"Tyler was extremely helpful and accommodating and helped me on very short notice with 2 plumbing projects recently, even spending almost an entire Saturday working when a washing machine install ended up being more work than expected. He is professional and extremely reasonably priced. Will definitely recommend and use for all of my plumbing needs."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"

keep mold from returning.  Since I have respiratory issues, it seemed a necessary expense.  They did not have the proper light on the truck so we had to reschedule the install for a week later and that appointment also had to be rescheduled for the following day.  I was very happy with the work done, though only time will tell if it really was an issue for my health problems and I certainly know it needed to be done.  I would highly recommend this company to anyone and have done so.  I am going to write it up in the condo newsletter as something all should address and have told friends and family who have any respiratory issues about having it done.  I was told they will maintain the light every two years at no expense.  My suggestion would be that when someone is interested in booking there be more information about the possibility of needs to educate the consumers involved.  Once they are in the house doing the job it is too late to compare pricing for the work.

"Work with Tylor. His quality and customer responsiveness is top notch. I had him install 3 mini splits in our home. I originally wanted Mr Cool.. He coached me into upgrading to Mitsubishi for our area due to it’s significant quality increases vs Mr Cool and he was able to purchase and install faster and significantly cheaper than the “Home Depot” “Mr Cool” 3rd party install pricing company Highly recommend Tylor and his work"

Install Boiler FAQs, answered by experts

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

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.

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.
