What Happens After You Book

You'll get a confirmation right away. 

Your appointment details land in your inbox as soon as you book, no waiting on a callback to confirm the time.

Payment is handled at the time of booking. 

You'll know the cost upfront rather than being surprised by it when the technician arrives.

We show up ready for the job you booked. 

The technician we send already knows what you scheduled, a repair call, a maintenance visit, or an installation estimate, so there's no re-explaining your situation at the door.

Booking FAQ

  • Is D's Air & Heating an authorized Lennox dealer?

    Yes. We're an authorized Lennox dealer, also authorized for Carrier and Green equipment, serving Chicago and the surrounding suburbs since 2009. Learn more about our Lennox dealer status.

  • Do I have to pay when I book online, or later?

     Payment is handled as part of the booking process, so you'll know the cost before a technician ever arrives. If your situation needs an on-site estimate first, we'll walk you through that at booking.

  • Can I book an emergency appointment online, or should I call?

    For a system that's completely down, calling 773-940-0965 gets you the fastest response. The online tool works well for scheduled service, tune-ups, and estimates where timing is more flexible.

  • What if I need to reschedule after booking?

    Contact us or call 773-940-0965 and we'll move your appointment to a time that works better.

  • Do I need to know exactly what's wrong before I book?

    No. Pick the service category that's closest to your situation, and our technician will diagnose the actual issue on-site.

  • Does online booking cost more than calling?

    No. Booking online costs the same as calling, it just skips the hold time.
