I needed a new hotwater heater. The one I had was in a crawl space.
ARS said that code would not allow them to replace it and the only solution was a tankless system costing $5200. I got two more quotes, both of which informed me that the code only applied to new construction.
Bottom line - I have a new hot water heater for $1200. OH, and I checked the cost of a tankless system from both reputable companies - $3500.
Reason of review: Pricing issue.
