I am looking to upgrade an existing, but very old and underperforming, Trane. I have a toss up between two make/models of air handler and heat pump replacements. I say 'toss up' because what do I know about HVAC? Hence, I post this question to a Pro!
Here is what was spec'd for my home:
Lennox Elite Series - XP13-024 Heat Pump
Lennox Merit Series - CBX26UH030 Air Handler
Trane XR13 Heat Pump 4TWR3024C1
Trane GAF2A0A24S21 Air Handler
The cost difference between the Trane and Lennox systems is minimal. My question is not whether these are the right units for my home. (I trust that my HVAC consultant did the math correctly and spec'd out properly matched systems.) Rather, I want to know more about the longevity and reliability between the two. How do they compare against each other? Is one typically more costly to maintain over the years? Does one have a bad reputation over the other? Or, rather, does one model have more issues over another model in the same brand family? How do the manufacturer's warranty stack against each other?
Any advice would be greatly appreciated. I understand that any answers posted are your opinions only and not an indication of which replacement I should purchase. I would, nevertheless, like to weigh the opinions of others with my own. I don't know anything about HVACs, makes and models. All I know is that it should keep my house cool in the summer and warm in the winter and my existing unit does neither.
