"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!"

"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."

"Mo was a very able, responsive and professional technician who installed our furnace in one day and our new boiler two days later. He patiently answered my many questions, walked me through why we needed two new units (instead of repairing our old ones) and worked well and efficiently. It was painful to have to pay that much money at once for a furnace and a boiler, but Mo made it as positive an experience as it could have been. I am grateful to him and his assistant for their work and professionalism."

Install Boiler FAQs, answered by experts

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.
