I met Max on Boxing Day, 2016. Our furnace, which we inherited when moving a few months prior, decided to suddenly die on us. I called every HVAC company in Durham. Only one answered: Max. He showed up a few hours later, removed the old furnace and installed a new one. Which we'll be forever grateful for and won't forget.
This time I just wanted our furnace and humidifier checked. Sure enough, the humidifier filter was clogged up. And the thermostat's batteries needed changing. All minor, but it made a difference.
Needless to say, Max has my highest recommendation. I've had some good luck on Homestars, but he takes the cake.
