A typical AC tune-up service includes a full system cleaning, performance testing, safety checks, and minor adjustments to keep your air conditioner efficient and reliable. Most issues we prevent come from dirt buildup on coils and loose electrical connections that strain the system. Technicians perform this work daily for homeowners around Elgin, and we often find cottonwood fluff clogging outdoor coils after late spring.
Here’s what’s usually included:
- Clean condenser/evaporator coils and remove debris.
- Check refrigerant charge, temperatures, and pressures; look for leaks.
- Inspect and tighten electrical connections; test capacitors and safety controls.
- Replace standard filter and thermostat batteries; verify airflow and provide a post-tune-up report.
