Seasonal furnace maintenance before winter to catch issues before they become no-heat emergencies.
Quick Answer
A pre-winter furnace tune-up catches most no-heat emergencies before the first cold snap, including carbon monoxide safety checks.

Common Issues We Fix
Furnace Tune-Up Troubleshooting Guide
"Annual inspection" — what's usually going on
This is one of the most common calls we get related to furnace tune-up. Often the root cause is a clogged filter, a tripped safety switch, or a thermostat miscommunication rather than a major mechanical failure. Before calling for service, check your air filter and confirm nothing is blocking the outdoor unit. If the issue persists, a technician can usually diagnose it within the first visit.
"Filter and airflow check" — what's usually going on
In a Chicago winter or summer, this kind of issue can escalate from an inconvenience to an emergency quickly. If you notice this symptom during extreme weather, don't wait — continuing to run a struggling system can cause secondary damage that turns a repair into a full replacement.
