"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!"

"7/30/19 contacted Home Advisor for a plumber referral because plumber we were using could not resolve the issue. Tom Brady called within five minutes of me submitting the inquiry. I forwarded information regarding the air switch error code, so he could research the issue for our condensing boiler. He followed up with NTIs Tech Support to fully understand the error code and possible solutions. We set up an appointment for 8/8 for him to assess the system. The first thing he did was check the air intake for obstruction and found a honeycomb nest. The previous plumber said there was no need to check the intake so never checked. He assessed the system, identified parts to be replaced, and set up an appointment to return to install parts and recharge the system with glycol anti-freeze which the previous plumber did not do. 8/21- Tom returned, installed parts, checked and adjusted the CO2 (which the previous plumber could not do because he did not have the tool), recharged the system, and advised our 15-year-old boiler was in good shape and did not need to be replaced. This was a relief given the previous plumber suggested it did need to be replaced. We are thrilled with Toms service and highly recommend him. He is thorough in his research and demonstrated he is a highly skilled plumber in analyzing/repairing our system. Since he completed the work we have on-demand hot water every time we called for it."

"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)"

Install Boiler FAQs, answered by experts

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

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.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Most installations take 2-5 days, including old system removal and setup.
