What a wonderful experience. We were really nervous because the first company that came out (PlumbLine, reviewed separately) spent only 30 minutes looking at our system, indicated there was nothing they could do, and still charged us $250 for a certification they couldn't do and that we never asked for. The technician from Aand B Mechanical was wonderful and treated my husband with respect (husband has over 40+ years as an electro-mechanical engineer with most of it being in the HVAC business). He not only accepted, and used the Oand M/Service manual my husband provided for the unit, but he spent nearly 2 hours inspecting the system, made just a few minor tweaks, and reported that the system was safe to use and functioning properly. We would definitely recommend and use these folks again and we will make sure to pass along their name to the new owners of our house.
Description of Work: Inspected boiler/furnace.

We had used A and B for yearly maintenance for 22 years, maybe why our old furnance lasted 24 years. They worked with us when it started having problems, at first thought the thermostat , then control module. They came out twice and got it going on very cold days and nights. The service techs Derek and Nate, and their boss Dave the owner, were very patient and they diagnosed eventually a problem with the mother board. They could have fixed it, but the smartest thing we thought by then, was a new energy efficient furnace for our difficult to heat tri-level home. They did not talk us into this. Their heating/AC expert Bruce led us through the options so we could make an intelligent decision. We are very happy with the new one which is heating much more evenly, more comfortably, quieter, and easy to adjust. We highly recommend them. The price was in line with what we researched and we wanted a high quality, energy efficient furnace. With the other company we called when this first started, the technician immediately started saying that everything was wrong with the type of furnace we had and wanted us to buy a new one practically on the spot. This was Applewood, similar to the review I read above. I will review that separately.
Description of Work: Got our old furnace running when it stopped working on a bitterly cold night, worked patiently over several visits to diagnose the problem. It was very old and we ended up buying a new furnace from them. They did not push us into it.

My heating system sounded as if it were about to completely go - as if the motor were on its last legs. I was able to get an appointment the same day , unusual, given the cold, and time of year. they were prompt, diagnosed effectively - it was a very minor isue, easy to fix and not expensive. Once before I called them for help on the same unit, except during the summer for the A/C I had already called two other companies who had come in, charged me, did not fix the issue and never returned my calls for follow up - i will rate them later. A & B came in the technician explored every single possibility, again diagnosed correctly and since it did not require any fixing - tjhey never even scharged for the visit. They are very honest, very good at what they do and I trust them 100% I highly highly recommend them
Description of Work: fixed furnace this visit - last visit managed to get the A/C working when no one else could!

Dave and crew did an excellent job. They were punctual and professional. Dave made recommendations on the number and locations of heat runs as well as modifications to improve the subfloor ventilation. The end result was a quality job that significantly improved the warmth of the basement.
Description of Work: HVAC for Basement remodel. 7 Supply runs, bathroom exhaust venting, 2 return air intakes, 3 existing heat runs moved and subfloor ventilation modification.

A & B has performed my annual service for 6 years and even installed my system. They have been a screw up from the very beginning and now I find them actually cheating me on an annual basis. I would never use this firm and suggest others run the other direction.
Description of Work: I had requsted my annual AC service and had my 3 AC units checked out. My tech, Derck was here to perform the service and after he finished I noticed my system wasn't cooling my home like it was before he arrived. I called Derk back and he looked over the system and said he thought the repairs would be upward of $600 for a part but wasn't sure of the actual repair until he talked with Dave the owner. They said they would be back to me in the next 2 or 3 days. That never happened. I went into there office and asked when they were going to get back to me. The office people indicated within a few days. I never heard back from them in the following week. I called another HVAC firm who came by and inspected my system and found that no actual service had been performed by A&B as they indicated and that the problem was a minor $10 repair part. So for all the years that I used A&B HVAC to service my AC and Heater, I find out they never did anything but charge me a high fee and did not perform any maintenance services.

THIS COMPANY WAS OUTSTANDING. THEY NOT ONLY CAME IMMEDIATELY, BUT THEY GOT US THROUGH, NOT PRESSURING US TO BUY. THEY WERE SO UNDERSTANDING OF US NEEDING HEAT IMMEDIATELY, BECAUSE IT WAS FREEZING, SO THEY CAME IMMEDIATELY AFTER WE CALLED. THEY ALSO DID A TEMPORARY FIX TO GET US THROUGH UNTIL WE COULD PURCHASE A NEW FURNACE. THEY DID SUCH A GREAT JOB THAT THE FURNACE IS STILL WORKING!!!! WE WILL DEFINITELY GO BACK TO THEM. ANY OTHER COMPANY WOULD HAVE TOLD US THAT WE NEEDED TO BUY A NEW FURNACE RIGHT THEN, THEY REALLY TRIED EVERYTHING TO GET THE OLD ONE TO WORK THROUGH THE HOLIDAYS. THEY KNEW WHAT THEY WERE TALKING ABOUT AND DID AN OUTSTANDING JOB.
Description of Work: OUR FURNACE DID NOT WORK AT ALL IN THE DEAD OF WINTER. THIS GREAT COMPANY CAME OUT ON A HOLIDAY AND FIXED IT SO IT WOULD WORK TEMPORARILY UNTIL WE COULD GET A NEW ONE INSTALLED.
