It's not that we're freezing, but we do need to figure out what's wrong and get it fixed. Not in a million years would I call the crooks who installed it, but I can't get hold of the one person we'd trust. I got a recommendation from our neighbors and - surprise!! - no call and no show. What is with these people?! So.... if you know someone who is dependable and knows what they're doing, please pass along a name and number.
