    "Every step was smooth and competently handled."

    We contracted Marx to replace our aging oil furnace with a high-efficiency heat pump. They arrived, promptly and prepared, on the agreed-upon installation date, protected walls and floors, worked diligently, and cleaned up afterward. Very professional!

    My furnace suddenly died and Marx Mechanical staff rearranged their schedule to be here the next day to replace my furnace (in a snowstorm). All my questions were answered and they even helped me set up the Daikin app on my phone.
