If a Phoenix HVAC company advertises a "$49 summer tune-up" — they're not actually tuning your system. They're driving sales calls. Here's what a real annual tune-up should include before peak season.
The 21-point checklist
- Thermostat calibration check
- Refrigerant charge measurement (not just "top off")
- Indoor coil cleaning
- Outdoor coil cleaning
- Condenser fan motor amperage
- Compressor amperage
- Capacitor capacitance test (degraded capacitors cause 80% of summer failures)
- Contactor inspection
- Drain line flush
- Drain pan inspection
- Float switch test
- Ductwork visual + leak check
- Return-air filter swap
- Blower motor amperage
- Blower wheel cleaning
- System startup amperage
- Temperature split measurement (supply vs return)
- Refrigerant line insulation check
- Disconnect box wiring inspection
- Static pressure measurement
- System operational efficiency calculation
This takes 75-90 minutes done right. Charging $49 means cutting half the checks.
If your tune-up was done in 20 minutes, you didn't get a tune-up. You got a sales visit.
Our $99 single-visit tune-up and $179/yr Comfort Club include the full 21-point. Real work, written report.
