"We had an older Heatmaker combination unit boiler that was 32 years old that needed to be replaced. We started out with several estimates and first decided what could be used in our space constrained garage. We decided on a Navien combination unit and focused a obtained a couple more estimates. Dawson in fact was one of the last estimates we obtained. While Dave from Dawson had the benefit of us being well along the learning curve, he was able to answer all of our questions about the new unit and how best to solve the condensate dilemma. He even was spot on with regards to treating our well water to minimize scale buildup in our new boiler. We knew we had reached that point where we felt we had found the best installer in Dave. Dave verified his condensate solution with the local township inspector and we scheduled the install date in two weeks. Carlos and Pablo showed up on time and dismantled the old unit and piping and did a first rate and well thought out installation job. Carlos had extensive experience installing these Navien units and it really showed. They managed to work in a tight space that PSE&G’s installers would not have with relocating a well tank. After all the plumbing was done, Ricky did the electrical work and adjusted some final dip switch settings before firing up the new boiler. Dave and his crew really are top notch. His front office staff (Wanda and Ondrea) made the PSE&G interest free financing and permitting approval process seemless. We are looking forward to the operation and efficiency of our new high efficiency boiler for years to come. If you are installing a Navien high efficiency combo unit, we highly recommend using Dawson Mechanical!"

"Another great service from GOOD TIDINGS. Steve and his assistant came in and explained thoroughly the job that needed to be done and offered great advice for preventative maintenance. They replaced my rear outdoor faucet , shutoff valve handle , and heating system tune up. Don’t hesitate to use this great company."

"the process was better than I expected. The sale man knew what he was talking about . The installation crew had worked for the company a long time and were also very knowable . When we could not understand a few things they sent out a serviceman just to show us how it works. They also directed us towards financiers and reabate availability."

"The technicians performed routine maintenance and repair of two boilers their company installed two years ago. They did a thorough job of flushing the water heating lines, testing the system, and re-installing a low-water shut off valve that had failed last year. I have used this plumbing company for years and will continue to do so, highly recommended to people in the Northeast New Jersey area."

"Great Experience with Kevin guiding us with the proposal of a Central Air and Furnace replacement. Very professional and answered all questions timely. No hard sell at all. We did have an existing Lennox AC. The install team of Shakil, Ty and Brandon were just as professional. True to their proposal, they came in and installed both systems in one day. Left the area neat and clean."

Install Boiler FAQs, answered by experts

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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.

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.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
