"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!"

"Tom did an incredible job. We had no heat and no hot water with freezing temperatures outside. We were told by other companies that the boiler was beyond repair and had quotes from $16,000-$21,000. When I told Tom I was told the boiler could not be repaired, he insisted on seeing it for his own evaluation. He came in on a weekend and fixed it for a completely reasonable and affordable price, saving us over $15,000! Best of all our heat and hot water are both back and the house is once again warm and toasty! We are saving his number and will hire him again without hesitation. He is honest, reliable and trustworthy."

"I had such a great experience with Liv Air! They serviced my boiler, and from start to finish the process was seamless. Leo is incredibly professional, easy to speak with, and genuinely such a nice person. He?s honest, reliable, and you can tell he truly cares about his customers. The technician who came to replace the parts was also wonderful ? very clean, respectful, and efficient. I?ve dealt with other companies before, but no one even comes close to the level of service Liv Air provides. Their pricing is fair and reasonable, and they answer calls right away, which is so rare these days. I?m honestly taken back by how great they were. I highly recommend Liv Air!"

"One of Gold Medal service rep stopped by to assets the project. He was very knowledgable and informative. He explained the benefit of having this type of service done by a professional person. I immediately hired them to install the gas line for my dryer. Unfortunately, I could not complete the job due to family circumstances. The rep understood and was the job was canceled without any penalty."

"We ended up going with a tankless solution that was installed the next day. Everything was completed in a single day (including removal of the old tank). I can't speak highly enough of the guys who were here, they were all professional and courteous. I would definitely recommend Water Works and hire them again (so much so that I signed a service contract with them for the new unit)"

"Although I never ended up using Todd Weber's service, because the original installer finally contacted me, he did call me back promptly and was able to schedule a visit on very short notice. He seemed very knowledgeable, caring and very dedicated to his business - something I find lacking with many service providers. If I were not moving away form the area in a few weeks I would certainly keep this serviceman's number handy."

Install Boiler FAQs, answered by experts

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.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

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

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

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.
