What's Actually Included in an AC Tune-Up?
A real AC tune-up covers cleaning the condenser and evaporator coils, checking refrigerant levels and pressures, tightening electrical connections, lubricating moving parts, inspecting the fan motor and blower, clearing the condensate drain, and testing thermostat calibration — a specific multi-point checklist, not just a quick filter swap.
Step by Step: What Happens During the Visit
1. Initial walkthrough: We ask about any comfort issues you've noticed and check the thermostat settings and history.
2. Filter and airflow check: Inspect or replace the filter and verify airflow at supply and return vents.
3. Coil cleaning: Clean the outdoor condenser coil and inspect the indoor evaporator coil for buildup or damage.
4. Refrigerant check: Measure pressures and superheat/subcooling to confirm the system is properly charged.
5. Electrical inspection: Tighten connections, test capacitor and contactor condition, and check voltage/amperage draw.
6. Condensate drain: Clear the drain line and check the pan for standing water or algae buildup.
7. Operational test: Run a full cooling cycle and verify the temperature differential between supply and return air.
How Long Does It Take?
A thorough tune-up typically takes 45-90 minutes per system, depending on how much cleaning the coils need and whether any minor adjustments are found along the way. A visit that's done in 15 minutes almost certainly skipped several of the steps above.
What a Fair Price Includes
A fair tune-up price covers the full checklist above, not just a filter change and a cursory look. Some companies advertise a very low tune-up price specifically to get in the door for an upsell — if the visit doesn't include actual coil cleaning and refrigerant/electrical checks, it isn't a real tune-up.
How Often Should You Schedule One?
Once a year, ideally in spring before peak cooling season, so any wear that's found can be addressed before the system is under its heaviest summer load in the Birmingham Metro's heat and humidity.
Will a Tune-Up Fix a System That's Already Not Cooling?
Sometimes — if the cause is something a tune-up addresses directly, like a dirty coil or low refrigerant caught early. But a system that's already failing needs a diagnostic first to identify the specific problem, not a routine tune-up visit.
