My hot water tank was leaking while I was at work. They responded promptly to help my family stop the water leak to prevent damage and replace the hot water tank. Great communication and explained everything. No pressuring or up selling.

MaxPro replaced my aging water heater, they were extremely professional, very easy to work with, explained multiple options, they were able to install my new WH 24 hours after I contacted them, I ended up going with the Heat Pump WH, which qualifies for a SnoPUD rebate, I would highly recommend them.
