Pick the problem that matches your system. You'll get preliminary information, likely causes, an estimated cost range, and a way to reach a local contractor.
HVACFinder.io provides general information only and does not diagnose HVAC systems. Possible causes are listed to help you have a more informed conversation with a contractor. A licensed HVAC technician should inspect your system before any repair. If you smell gas, see sparks, or suspect carbon monoxide, leave the home and call 911 or your gas utility.
Use the triage tool and free cost estimators to understand what's wrong, what it should cost, and whether to repair or replace.
