I've received 3 bids.
1) Ruud; 14 seer; 3-ton (I've requested a quote on a 3-1/2 ton) - this is the guy I've been using for 15-20 years.
3) Lennox; 13 seer; 3-1/2 ton - this bidder suggested I go 3-1/2 ton for the hottest texas summer days.
2) Trane; 13 seer; 3-ton - this bidder wants me to add on a heat pump and variable speed - he gave bids for a 13xr and a 19xl
Bids in order of cost.
Suggestions? I do want to make sure it stays cold in the summer; never have had trouble keeping it warm in the winter.
