Post back.

How can you call this a bid when it contains no pricing or equipment information?

I would certainly NOT be quick to install a 5 ton system in a 2200 sqft home in Orange County! I dont expect the homeowner would be very happy down the road. A full load calculation needs to be done to determine proper sizing. Proper duct design is important too. Much more information is needed for a reasonable and competitive bid.

Its a day and night furnace and day and night air conditioner.
both are 5 ton 80% efficiency
Total cost was 8500.
Sorry I cant believe i left that out.

Oversized!
