Yeah I get that and I have looked multiple ways, but we also get lots of 40 degree days well within the HP wheel house and the Heatpump after rebates is a push vs the straight AC. Electric Rates: Residential Energy Charges: $0.0945 per kwh for First 400 kwhs per billing period $0.0715 per kwh for Next 1400 kwhs per billing period $0.0535 per kwh for Over 1800 kwhs per billing period Gas Rates: Winter (November - April) 1st 30 Therms �" $0.85579 + RG PGA Block 1 Over 30 Therms - $0.00 + RG PGA Block 2 RG PGA Block 1 as of 11/16/2012 - $0.33492 RG PGA Block 2 as of 11/16/2012 - $0.57903 Keep in mind that even when its very cold, with my current furnace I rarely go over 100Therms in a given month during the winter. The xv95 is $800 more after rebates etc..

mud I think it is a ridiculous price for what you get. sure it is a new mdl number with a heavy price but really what do you get. this communicating business seems to be more important with Trane than performance/efficiency numbers. here are the matching AHRI numbers for your system. 3220731 Active Systems XL20I TRANE 4TTZ0048A1 4TXCC008CC3 *UD080R9V4 46000 12.00 17.25 doesn't look like much too me. short on cooling BTUs, a very mediocre EER. does not qualify for the Fed Energy Eff tax credit. I took a look at the HPs as well and only up to three ton models qualify for the HP credit. I personally think Trane is snookering the market. As one of the pros said yesterday about this recently introduced model-"where's the beef?" IMO

village I took a look at the CEE HVAC directory today for matching AC systems for the 3.5 ton XL15i vs the 4 ton 2 stg XL16i. There was less than 1 SEER difference between these two models-15.75 vs 16.25. I would not want to be undersized though for Florida. If you are certain of your sizing, then I would go for for the XL15i. Don't use Trane stat. Insist upon the Honeywell Vision Pro IAQ which handles humidity control better than anything Trane offers. You may save a few dollars looking at the comparable Am Std Allegiance systems. IMO Here is a link that might be useful: CEE HVAC Directory

codeslinger First off,I am not a Trane basher. I live about 1 1/2 hrs down 26 from your area and have a Trane dual fuel system. But I would not have the XL16i for several reasons. 1.efficiency numbers are poor for such high end HVAC 2.performance numbers for both heating and cooling BTUs are very poor. 3.I don't believe Trane recommends the XL16i for zoning-it has about 70-100 split between low and high stage. 4.There are just too many anecdotal stories about issues relating to the XL16i. 5.The HW VisionPro IAQ feature "dehumidify on demand" is not compatible for the XL16i which is important for your area/climate. See below AHRI Performance numbers for various configurations.

I agree with Ryan's comments. As far as Clean Effects and EACs, I see no problem as the fire related issue has been resolved. There may be a small price advantage for the built-in Clean Effects. As far as the performance/efficiency numbers, there is no difference. I am not a fan of EACs because of maintenance/cleaning responsibilities for the homeowner. There is something to say about the old adage "keep it simple". Most homeowners will not adhere to properly maintaining EACs. For over 99% of homes, a good 4-5" pleated media filter cabinet MERV 10 is more than adequate for IAQ and protecting blower motor and evap coil. Changeout is up to one yr interval, takes a couple of minutes, and is very easy. Foe two systems, you should be able to negotiate a good price on the 10 yr ext warranty-parts and labor. A price below $1k for two systems would be good. Ductwork install is relatively cheap as long as its sized correctly and insulated properly=R8. I see no reason to zone one room as long as it receives the recommended CFMs to match the load. I would want to see a written copy of Man J and Man D and review with dealer. If you do decide on the XL15i, you should insist on the HW VP IAQ stat. IMO
