Sheet Q-701 · Questions
Questions we get on the phone
Straight answers, the same ones our dispatcher gives.
Q01 Do you offer same-day HVAC repair in Chicago?
Yes. Call or book before 11 am on a weekday and a Draftline truck is at your door the same day. In 2025 we made it on 94% of weekday repair calls.
Q02 What does a service call cost?
The diagnostic visit is $89 and it is credited back in full if you go ahead with the repair. You get a written price before any work starts.
Q03 Are your technicians licensed and insured?
Draftline Mechanical holds City of Chicago mechanical license 055-00817, carries $2M general liability, and every technician on the road is NATE-certified.
Q04 Do you offer financing on a new furnace or AC?
Yes. Replacements over $2,400 can be split into 18 months at 0% APR for approved credit, or longer terms at a fixed rate.
Q05 Which areas do you cover?
Chicago plus Evanston, Oak Park, Skokie, Cicero, Berwyn and Park Ridge. If you are just outside that line, call and ask; we often say yes.
Q06 How do I know what size AC or furnace I need?
Try the load calculator on this page for a ballpark tonnage, then we confirm it with a Manual J load calculation at your home before quoting. We never size by the old unit alone.
