PM sent. I don't know if they will go that far though.
edit: PM not sent. I can't find the button(I've sent them in the past). I'm a GC and I have a good hvac contractor. Send me a PM and I'll send you his name & number.
I am building a house now and I got prices from 5 different companies. Stiles heating and air beat the next closest bid by $2000. They beat the worst bid by $4000. They got the job.
