Best Heating & Air Conditioning / HVAC In Berkeley Heights

“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!“

“We have a colonial split level and could never get the half 3rd floor cooled/ warmed. We were prepared to put in a second condenser unit but Chris recommended a different more economical solution. They responded to our subsequent questions quickly... So Happy with our choice.“

“Cleared drain line. Toilet and tub were clogged. we had two technicians. The first one communicated there would be a guarantee for the work because we were Having the camera look into the drain. The second technician three days later said there is no warranty unless we do a jetting which was ridiculously priced at over $4000 for two drains over $2000 for the one drain that was clogged. so communications was poor and contradictory. We also felt the overall price was exorbitant.“
