Get matched with top furnace / forced air heating system install or replace pros in Gillette, NJ

"Our oil burner began emitting Carbon monoxide (CO) early one morning and stopped working. We called several repair services and no one called us back in a timely manner. We found AB Castello's on Angie's List, completed the Angie's List form and Desmond from AB Castellos called us immediately. Robert arrived less than an hour later. The first thing he did when he arrived was check for CO emissions. He then determined that our 16 year old furnace needed to be replaced. Later that day we received an estimate via email, had all of our questions answered on the phone, and arrived the next morning prepared to remove and replace our furnace. Desmond and Robert worked all day, into the evening, in order to install the new furnace. They were determined not to leave us one more night without heat. They were very polite, pleasant, neat and did an excellent job. I would highly recommend this company should you need service of any kind. Their response time was better than almost any other contractor we have hired, and their work excellent. They also cleaned up very well before leaving our home, and were very careful as they carried equipment in and out of our house. I cannot speak highly enough of them"

"They installed AC in our 1923 house back in 2006 and our AC bills are lower than our heat! Excellent courteous clean work. This past spring the fan motor for this system died and because of it’s design was an expensive repair but again the work was done fast and clean. Highly recommended!"

"After I talked to many companies about replacing my heating and cooling systems Overall Heating and Cooling were the misy resonate with pricing and professional company for the job. They were prompt to come out the next day and replace my entire heating and cooling system the same day. They were professional on every level possible and cleaned up after the job was done. I recommend this company for their services. AMAZING and I am very happy with the results"

"Great company! They've been super responsive when we've had questions or concerns, and deliveries are frequent enough that we never have to worry about running out of heating oil."

"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!"

"Kyle provided valuable information and insight on my heating system. He gave recommendations for now and future. I highly recommend him for his knowledge and service."

"Reliable, great customer service, and honest. Highly recommend them for all your heating and air conditioning needs. Alfredo came in and diagnose my furnace. He’s very knowledgeable and solved my furnace issue the same day. Went above and beyond to ensure the heat works like I informed the entire process while I was at work."

"The entire process was flawless. In the proposal stage, I was given 4 options detailing prices and differences in each option in great detail. There was also an explanation of why I needed a chimney liner. We signed the contract and work was started almost immediately. I was contacted via text and email with a description of all the techs being dispatched including photos and background information. The techs arrived as stated. My furnace was over 50 years old and in poor shape. The job site was prepared and all the old components were removed leaving the site as clean or cleaner than when they started. The tech fully tested the heat and air conditioning systems and showed me how to use and set up the programmable thermostat. Great job all around."

"Went great. Very professional. The workers were happy and friendly. Talked to a lady on phone very professional and helpful. Also spoke with the head of company very nice got a quote quickly. And installed water heater in a few days so family didn't need take cold showers. And furnace was fix a few days later before it gets cold outside. Thank you very much William"
