Been impressed by discussions here, so I thought I would ask:
1. I have a 20-year-old-plus Central AC. It works Ok, but is old and obviously not energy efficient. But I wonder if I should replace it before it breaks down some hot July and no contractor will see any reason to give me price discounts. Or is it right to wait until it dies?
So: Should I replace now? Or wait?
2. I have bids on a Lennox XC13 and a Trane XL 14i. Prices are pretty close. Trane installer would be Home Depot subcontractor. Lennox by a company highly recommended on Angie's list. Lennox guy did a heat load calculation, but is pushy. HD guy eye-balled it, but hasn't pushed me.
So: Which would be the better choice from the point of view of reliability and repair record: The Lennox or the Trane?
Many thanks in advance.
