Rittinger responded quickly. Alan, the tradesman they sent over was professional and quick. I hired them to install a clothes dryer vent and to open up a vent in my garage for the hot water heater. The work was high quality and installation was clean.

Called in the morning, and received a same day appointment. The repair tech (Andrey) sent me a text to let me know that they were on their way (within the 2 hour service window). The repair tech was able to find the broken glass in the drain tube which was causing the unit to not drain properly....
