Our 21-Point Air Conditioning Maintenance Inspection
When the Texas heat is at its peak, you need an AC system you can rely on 24/7. Our 21-point AC maintenance inspection ensures your system operates effectively:
- Confirm system operations and cycle through thermostat/comfort controller.
- Visual check of air filters; replacement available if provided by the customer.
- Measure supply and return air temperatures; ensure an 18-20 degree drop across the coil.
- Check system voltage for proper range (120V +/-5%).
- Verify blower motor amperage against nameplate rating.
- Test door safety switch, if present.
- Inspect primary and secondary condensate drain lines for proper water flow.
- Check the operation of float switches, if present.
- Conduct a visual inspection for oil and refrigerant leaks at the indoor evaporator coil.
- Check water heater exhaust, if visible in attic AC location.
- Inspect for water leaks.
- Evaluate ductwork condition.
- Verify condenser fan motor and compressor amperage against nameplate rating.
- Inspect contactor for operation, pitting, and voltage consistency (120V & 24V).
- Measure run capacitor microfarads against nameplate rating (+/- 6%).
- Assess system suction and discharge pressures against manufacturer specifications.
- Measure system suction and discharge temperatures at the condenser.
- Calculate system sub-cooling for TXV systems.
- Calculate system superheat for piston/orifice systems.
- Check for oil and refrigerant leaks at the condenser coil.
- Basic rinse of the condenser coil (customer provides hose within 40 feet of the unit).
