You can e-mail or call Trane directly and ask them which condensers come with scroll compressors and which have reciprocating compressors.

I am assuming you are looking at HP systems.

I would stay away from Lennox.

The minimum performance metrics for a new heat pump system that I would look for is R-410 frig, matching var speed air handler, 14-15 SEER, 12 EER, 9 HSPF, full BTUs for the size in both cooling and heating mode,scroll compressor.

For the XR14 and the XL14i, other than cost, the differences are noise, warranty, efficiency depending on size, and the funky top that the XL14i has. Depending on size and model, Trane uses both recips and scroll
compressors. You will have to ask dealer.

I am listing below three performance configurations for the XR14, XL14i, and XL15i three ton. Numbers are from the CEE HVAC directory.

1104157 Active OEM XR14 WEATHERTRON TRANE 4TWR4036A1 4TEE3F39A1 36400 12.00 14.00 31800 9.00 19900

1104184 Active OEM XL14I WEATHERTRON TRANE 4TWX4036B1 4TEE3F39A1 36400 12.40 15.00 31800 9.00 19900

1382162 Active OEM XL15I WEATHERTRON TRANE 4TWX5036A1 4TEE3F39A1 36000 13.00 15.00 34000 9.00 23600

As you can see, there is very little difference between the XR14 and XL14i. Both these systems have poor heating BTUs but for your Florida location, this should not be consequential. You can see that the XL15i has the overall best numbers.

I would not use any of the Trane stats-go for the Honeywell VisionPro IAQ for superior dehumidification.

I agree with tigerdunes. You'll have to ask your dealer what size to see if it has a scroll compressor in it.

I don't necessarily agree with the "I would stay away from Lennox." :-) I think it depends more on your area and whether you have Lennox dealers. For my area, there are plenty of Lennox dealers.
