I decided to replace aging (rental) conventional gas water tank with a power vent model. Air Quality One delivered and installed a heater for a price that was just slightly higher than I would have paid for an equivalent heater at a big box store. The installers were professional and tried to oblige my requirements (I'm pretty fussy) about exactly how to do the install. Amir and his coworker arrived on time, did a great install, explained the basics of how to use heater and how to register with the manufacturer. I'll use this company again when it's time to repair or replace my aging furnace.
