I am looking at that right now as my #1 choice. The Water Furnace 7 Series looks amazing, but the price might be out of my budget.
tons cooling heating
3 13,000 - 38,000 14,000 - 41,000
4 19,200 - 49,000 19,000 - 55,000
5 23,200 - 60,000 23,000 - 65,000
The 4 ton unit would be perfect for me, I'm trying to find out prices on any scratch and dent models they might have. The other model I'm looking at is a Daikin Mcquay with variable speed compressor.
tons cooling heating
3 15,900 - 38,900 9,900 - 30,100
4 17,200 - 50,900 18,800 - 40,700
The heating max btu's are a little deceiving. I believe Water Furnace uses the top capacity possible, such as 118%, as the max number. Daikin on the other hand uses 100% as the max number, even though the unit can go above that. I found a chart that showed the Daikin 4 ton with an actual top of around 53,000, inline with the Water Furnace numbers.
