"These are different times with the virus. Because of my age I have to be careful. And so it's important to say that DMC followed all protocols without prompting, with masking, social distancing, and was even careful to contact no surfaces unnecessarily, and so was very professional and courteous with these not-so-pleasant issues. But to back up a bit, knowledgeable diagnosis of the problem began with the initial phone call. Experience counts, and the diagnosis was confirmed quickly upon arrival. Tests were done in front of me, and the problem explained clearly. I had called in early morning, and was scheduled in, despite three other jobs planned for Les (the tech) ahead of mine. He arrived in the first fifteen minutes of his predicted time-window, and his work, despite challenges described below, was as efficient as his predicted arrival, The job was complicated first by the furnace not being installed in its most conventional and accessible way, and second, even though he would have made the replacement with a universal motor to save cost, the particular furnace required its specific part only. This said, he knew exactly where the nearest distributor was, and retrieved the necessary replacement quickly. Despite the difficulty of the disassemble/installation and having to retrieve and use only the specific replacement, his price point was well within researched averages, This was a great comfort, and another reason to leave this highest possible review for a top-flight service company. Based on such, DMC will be the first company I call for any further a/c or heating concerns. Thanks!"

"Henry is professional, knowledgeable & friendly. He knows what he is doing. Plus…shows up on time!!!"

"Outstanding service.  Technician arrived on time and performed diagnosis.  Although unit appeared to be working, it was not detected until later that the thermostat would not turn off the unit, so the new thermostat was not installed.  Technician and office personnel very helpful in coordinating return visit to install the new thermostat at no additional charge.
Normally, I do not write reviews.  These guys earned an A rating and my business for life.

"All of the parts required for the job were staged before the technicians arrived.  The technicians were very nice and competent and they put down a drop cloth to protect the carpet and rug leading to the stairs to the basement where the furnace was located.  They removed the old, flood damaged furnace and the old air conditioner.  They installed the new furnace, air conditioner, the new exhaust and combustion air piping required for the high efficiency  furnace and replaced the copper tubing from the new air conditioner compressor to the "A" coil in the duct work.  The technicians answered all of my questions and I was impressed with the finished product.  I would recommend this company to my friends and family.

"My gas fireplace is fog free and works great. He even installed a new fan for me. Thanks, Dan!"
