Maintenance plans are either a quiet bargain or a recurring charge for a guy to glance at your unit — depending entirely on what’s actually included. Here’s how to tell the difference, with real numbers.
What a legitimate tune-up includes
- Condenser and evaporator coil inspection/cleaning
- Refrigerant measured against manufacturer spec (not eyeballed)
- Capacitor and contactor tested under load
- Amp draws recorded on compressor and motors
- Condensate drain flushed and treated
- Thermostat calibration and airflow check
- A written report — including what’s fine
If the visit takes 15 minutes and produces no numbers, you didn’t get a tune-up; you got a sales funnel.
The warranty fine print
Read your equipment warranty: most manufacturers require documented annual maintenance to keep parts coverage valid. A compressor that dies in year six on an unmaintained system can be a denied claim and a $2,000 bill. The plan’s paperwork alone is worth something.
The math
A solid Columbia-area plan runs $150–$300/year and typically includes both seasonal visits (spring AC, fall heating), priority scheduling, and 10–15% repair discounts. Now price the alternative: one emergency after-hours capacitor call runs $250–$450. Industry data consistently shows maintained systems fail less, last longer, and run cheaper — the coil cleaning alone recovers measurable efficiency.
Break-even is roughly one avoided emergency call. Everything after that — efficiency, lifespan, warranty protection — is profit.
Who should definitely have one
- Units over 8 years old (failures get likelier; early detection gets cheaper)
- Rental properties (documented service protects you and your tenants)
- Lake homes and seasonal properties (a quiet failure becomes a mold problem)
- Anyone whose warranty requires it — which is nearly everyone
The bottom line
A real plan from a company that shows its work is worth it. A cheap “inspection special” that exists to manufacture replacement leads is not. Ask what the visit includes and ask to see the report — the answers tell you everything.
