A1 installed a new furnace and air conditioner to replace a 16-year-old system. Mike M and his helper James were very friendly, efficient, and supremely competent -- and dedicated! They arrived at 8 a.m. and left at 6 p.m., having not taken even a lunch break. We were greatly impressed by the level of service, and would have absolutely no problem recommending this company to friends.
