I need to replace an 11 year old outdoor gas/electric unit.
One company suggests the Trane xl1400 which is NOT dual fuel but does have "two-stage gas valve" for heating. It would be 3.5 ton, 14 SEER.
A second company could install the American Standard Triumph 3.5 ton, 14 SEER which is also the two stage heating for $1500 less. They tell me the Trane and American Standard models are exactly the same, only different labels. However, they also suggest a Rheem "dual fuel" unit. The price for the Rheem dual fuel is the same as the price for the Trane xl 1400.
Does anyone have any opinions, advise, etc. they would be willing to share regarding Trane vs. American Standard. And also the efficiency and benefits of going w/ dual fuel vs. straight gas heating.
