"The installation took place on December 1st and went really smoothly. The two gentlemen, RJ and Sam, who did the installation were very professional and efficient. They completed the job in record time and made sure that the area was spotless when they left. I would definitely recommend Clean Air Mechanical, the owner, Jon, was very accommodating and friendly. If I had any complaint at all it would be that this furnace is considerably louder than my old furnace, but that has nothing to do with the folks who did the installation. Thank you CAM, Job well done! Doug Young Belchertown, MA"

"Josh and his crew were amazing. I had an air handler that needed to be removed and a new one installed. Great price for removal and installation. It felt like they were done in no time! Highly recommend tandem mechanical. Out side central air condenser is next on my list and I will for sure have these guys back."
