“I had MJA Design do a complete HVAC renovation converting from a broken AC unit and oil furnace to a highly-efficient heat pump. Mike and his team are professional and knowledgeable. I am truly impressed by his passion to create the best possible solution for your needs, at a reasonable cost. Overall I am pleased with the quality of service, craftsmanship, and expertise of MJA Design and would highly recommend them for your next home project.”
