Quote on new HVAC system - Trane
Need your help. I am replacing my 27-yr-old A/C (5 ton York and gas furnace) and duct system. It is 2300 sq ft one-story house (built in 1985) in Dallas with 20 windows (double-pane).

The contractor came by and spent 20 minutes in the attic. He walked around the house. We are not sure that he did load calculation. He did tell us 4 ton is enough for this house based on his calculation (not sure how..)
Warranty is 10-yr manufacturer warranty. 1 year labor warranty.
Is this a reasonable bid? Are the equipments right for this house?
Thank you very much for any feedback.
