How to vet a HVAC contractor

1. Illinois has no statewide HVAC license, so ask what local license or registration your municipality requires and check it.
2. Ask for proof of insurance and any manufacturer certifications.
3. Get a load calculation (Manual J) before buying new equipment. Don't size by rule of thumb.
4. Ask which utility rebates apply (ComEd, Nicor Gas, Peoples Gas) and whether they file the paperwork.
5. Get the labor warranty in writing, separate from the equipment warranty.

Book a furnace tune-up in September or October, before the first cold snap. Book the AC tune-up in April or May.
