I have used the search function and realize that much of this discussion is already elsewhere. Forgive me for asking my specific question: I am building a new house in Houston, Texas. Considering the Lennox XC14 or the two-stage (two-speed? does that mean the same thing?) XC16.
1. Is the two-stage feature worth the candle? That is, will it save on electricity costs?
2. Does the two-stage feature also have something to do with humidity control?
Thanks. The house will be about 5,000 square feet, and the proposal is 4 tons down and 5 tons up. Power costs are approximately 15 cents/kwh. I expect summer ac bills in the $250-$300 range, but I hope not too much higher. I dont know because I live in a much smaller house now.
