I had a Rinnai RU 199i tankless installed last week by Ash and his team. Another great experience. This tankless unit and Ash and his team is highly recommended. Previously had a return vent moved, A/C unit moved from the back to side of the house and April Aire humidifier installed. It's nice knowing that I have a go to HVAC company!! No doubt who I'll be calling when my builder furnace gives up the ghost. Also great tips on how and where to move my floor drain.
