Honestly, customer service was less than helpful. I'm a high-volume builder in Boston, and after a heater recently died before my clients even moved in, I reached out to customer service about getting a replacement shipped out. They said I need to remove and send back the unit for repairs before a new one could be shipped. I ended up having to spend money to purchase a new unit and rush-ship it, as this item could hold up the closing, putting millions at risk. The unwillingness to work with me in this predicament or even help me place a new order made me never want to use this brand again. There’s a lot of competition in building products, in short. Do better. I’m part of a few nationwide builder groups and I’ve shared my experience with your company in the group, hoping they don’t make the same mistake I did. Thanks.
