Trane, RUUD, Lennox, Kenmore: how do you make a decision?
I live in a flat roof row-house in DC with flex ducts in a crawl space; and I now need to replace the package unit on my roof that heats and cools only the 2nd floor (approx 800 sq'); my current system has a cracked hear exchanger. We've been visited by nationals and local independents but no one has recommended the same machine. What direction would you recommend:
RUUD RRRL-C-024 (16 SEER residential, limited Lifetime HX)
Lennox 15GCSX-024 (15 SEER res, 20 yr HX)
Rheem RRPL (14 SEER)
Rheem RQPM (14 SEER)
Trane XL14C (14 SEER, 20ys HX)
Goodman GPG (15 SEER, 20 yr HX)
Kenmore (14 SEER)
Carrier (14 SEER)
We are leaning towards the Trane XL14C (14 SEER, 20ys HX), simply understanding the value of a long warranty on a heat exchange and a stainless steel HE. Any other thoughts on any of these machines would be greatly appreciated. -O.
