Definitely the best price out of everyone and they were able to replace my steam boiler in one day, 2 days after I requested an onsite quote. Was able to arrange financing through him. Most of the folks that service the area are larger companies asking at least 2k more. As a small business he was able to provide me with the best price. He was punctual and got the job done. Had one small issue and he was right back out to fix it.

Found this company through Angi HomeAdvisor. I wanted to get at least 3 estimates . Not only was AJB Mechanical able to offer me the lowest price to replace my Central A/C unit but he was the most professional of all. No slick talking, just straight to the point. He recommend top quality products and answered all my questions. On the day of the installation Andy was prompt, precise and engaged. Amazing work ethics and neatness. I highly recommend AJB Mechanical Heating & Cooling. Thank you Andy.

Cannot recommend AJB enough! Our induction motor went bad right at the start of winter and Andy came to our rescue with a new furnace at a very competitive price. He went over all the details and was able to get the system in just two days after the initial quote. An absolute pleasure to work with and I will be ready with his info any time a friend or family need some work done. 6/5 stars!

Gas Heating and Furnace Service
First, my project was to install, from scratch, a new HVAC system, including ducting, with tha furnace in basement (initially, it was upstears in a closed). Last year and early this year, I got 3 contractors on site, by direct call, and none of them answered my spefic questions but taking pictures and promising that will send an estimate. I never got it. I was getting anxious. So I got the idea go to Angi. First visit I got in the same day I put my request on Angie's site, called his boss advice me to just change the furnace. I could not, because the previous system was heating OK only one half of the house. Finally, next day I got AJB visit an made me happy. He understood perfectly what I wanted and my concerns and explained to better and quite ingenious solutions on my suggestions. I understood him perfectly because I have strong knowledge of aero-dinamicsor or fluid mechanics so I signed the contract right then. Now, I have a sweet warm house in every corner of it.

Demonstrated professionalism, integrity, and empathy during all aspects of the project, plus the rare event of having a contractor arrive on time for estimate and installation. It was a pleasure having no stress working with the owner Andy and his son. After having two other much higher estimates for inferior split ductless heat pumps than what Andy installed in my house, I was able to have the efficient system installed to fit my budget. So glad I chose a family business with lower overhead and stable expertise proven over their many years in business.

The owner Andy was a very nice and sweet man and he did the work by himself and I will give anybody credit for going up and down ladders, up and down ladders, up and down steps, up down steps and drilling holes in the brick and everything else. I have a brick home so it was a lot of hard work and he did a very very good job and I really appreciated it! And did I mention he was by his self !!! It took a couple days to be finally completed, but with the work that he had to do with the brick and the windows and everything I think he did a super job ! I would hire him again to do something if I needed too !! Thanks Andyâ ºï¸ also, I forgot to mention I think the price was pretty fair. I really do. I honestly think a bigger company Because of the overhead wouldâ ve probably charged me more.

Everything done exactly right, on schedule (ahead of what I was expecting). AJB quoted a Columbia boiler, which cost a little more than the others, but I believe will be worth it. Worked almost 13 hours the first day and a couple more the next day to get the job done. Cleaned the area and ensured everything was operating properly.

Gas Furnace / Forced Air Heating System - Repair
He charged $335.00 an hour... WAY too much. I will never hire AJB Mechanical Heating and Cooling for another project. He says that he did not charge that much labor, but instead charged me $370.00 for the pump which retails for $131.00 at Lowes which is .9 miles from here, a 5 minute drive. Still... charging an EXTRA $240.00 for running after the pump which is a 10 minute round trip is completely ridiculous. (That is a rate of $1440.00 an hour).

Andy from AJB Mechanical Heating and Cooling is a class act. He came to my home, did the work that was needed, recommended future work and maintenance and even came back to my home when I have further questions and concerns. I would recommend him and his company to anyone need work with their heating and cooling systems!
