Del-Air A/C -- Any good?
 

Trying to get some estimates to replace entire A/C unit ASAP. I saw an ad this morning that Del-Air is offering a $1250 rebate for a Carrier. A discount would be lovely but only if the installer does a complete job (replacing copper lines, etc.). So, has anyone used Del-Air. If so, what do you think? Who would you recommend? (Already have an appointment scheduled with Chuck Farrell.)
