- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended

- Good to know—
Missouri has no statewide residential building/mechanical code, so permit and inspection requirements are set locally by each city or county.

AC Maintenance in Hazelwood, explained.
What affects AC tune-up pricing in Hazelwood?
Pricing varies based on system age (many homes are 57+ years old), the type of service (basic tune-up vs. coil cleaning), and whether you choose a one-time visit or an annual plan. Labor rates in this tier 3 market are generally more affordable than in major metros. Additionally, if a mechanical permit is required by Hazelwood, that may add a small fee. The federal 25C tax credit (up to $600 for high-efficiency AC) can offset upgrade costs but does not apply to tune-ups.
Common AC issues found during tune-ups in Hazelwood
Dirty evaporator coil
Older homes often have dust buildup on coils, reducing efficiency and airflow. Coil cleaning ($85–$350) is a frequent recommendation.
Refrigerant leaks
With R-410A being phased down after 2025, older systems may develop leaks. A tune-up includes checking refrigerant levels.
Faulty capacitor or contactor
These components wear out over time, especially in systems over a decade old, causing the AC to struggle or fail to start.
