10 STARS IS NOT ENOUGHOn one of the hottest days of the year my AC stops working.called One Hour Air they made a appointment for me on Sept 9th.I then asked a friend for the name of a good HVAC contractorhe said to call Mark, he came the same day, got me up and running and didnt want to charge me to boot. I will be using Mark in the future

The proprietor, Mark Constantini, stopped by after 5PM on a Friday evening prior to a 3 day weekend to swap a faulty igniter on my furnace. Mark was cordial and communicative on the issue, and clearly outlined remedy and cost. The value was more than fair. I will engage Mark again if needed for my furnace or hot water heater.
