Air Conditioning System Tune-Up Special
18 Point Cooling System Check Up Includes:
- Thermostat – Check temperature display accuracy and tighten lose wires that can cause short cycling.
- System Performance / Split Temp – Measure temperature differential across evaporator coil. Split should be 18-20°.
- Air Filter – Clean or replace air filter, and inspect air return for air restrictions. (New filter will incur an additional charge)
- Air Ducts – Check for air leaks. A cool attic during warm months is typically a sign of duct leakage.
- Electrical Box – Tighten connections and check for metal fatigue and electrical overheating (bluish-green discoloration).
- Condensate Drain – Check drain for debris blockage and look for key signs of drain overflow (rust or stains).
- Air Distribution – Check airflow and inspect areas where homeowners are experiencing a lack of comfort.
- Plenum – Check the duct transitions for leakage caused by system vibration or poor installation materials.
- Evaporator Coil – Check for bacteria build-up, formicary corrosion, galvanic corrosion, and leaking refrigerant oil. Dirty coils reduce efficiency and decrease air quality.
- Run Capacitors – Test all capacitors for proper microfarad “µf” capacity (max permitted ± 10%) and inspect for signs of leakage or bulging.
- Refrigerant – Confirm and record refrigerant pressures if system fails system performance testing or any of the visual coil inspections. Add up to 1lb of R-410a refrigerant if necessary.
- Condenser Coil – Examine coil for straightness and cleanliness, and leaking refrigerant oil. Take and evaluate outside split temp.
- Compressor – Test amp draw and compare it to max on data plate. Tighten loose wires at contactor.
- Safety Controls – Check all panel switches and pressure controls to make sure they are functioning properly.
- Condenser Motor – Check the amp draw and compare it to the max rating. Check bearings and lubricate motor as necessary.
- Blower Motor – Same check as condenser motor along with blower wheel inspection and bacteria build-up.
- Insulation – Confirm all internal unit insulation is secure. Check suction line insulation.
- Contactor – Look for worn or pitted points and check for discoloration or severely burnt wires.
