HVAC Tune-Up Checklist: What a Proper Maintenance Visit Includes

An HVAC tune-up is only as valuable as what gets done during it. This checklist covers everything a thorough maintenance visit should include for air conditioning and furnace systems.

Why a Standardized Checklist Matters

Without a checklist, tune-up quality depends entirely on the individual tech. One tech does 22 things, another does 14 things, both call it a tune-up. A written checklist standardizes service quality, protects you from liability, and builds customer trust because you can show them exactly what was done.

Cooling System Tune-Up

Outdoor condensing unit:

• Inspect refrigerant levels and check for leaks
• Clean condenser coils and straighten fins if needed
• Check and tighten all electrical connections
• Test capacitor and contactor
• Lubricate fan motor bearings
• Measure amperage draw on compressor and fan motor
• Inspect disconnect box and service valve caps

Indoor air handler and evaporator:

• Clean evaporator coil
• Inspect and clean condensate drain line
• Test condensate pump if present
• Inspect blower motor and wheel
• Measure static pressure and airflow
• Check thermostat calibration and operation

Heating System Tune-Up

• Inspect and clean burners
• Test igniter and flame sensor
• Check heat exchanger for cracks, a critical safety item
• Clean and inspect flue pipe
• Test gas pressure at manifold and supply
• Inspect and clean draft inducer motor
• Test all safety limits and switches
• Check temperature rise against manufacturer spec

Filter and Airflow

• Replace air filter or verify customer will replace
• Check all supply and return registers for blockage
• Inspect ductwork for obvious damage at accessible points

What to Charge

Residential HVAC tune-up pricing in 2025:

• Single system: $89-149
• Two systems: $149-249
• Membership plan with 2 tune-ups per year: $180-300/year

Do not price so low that the visit feels disposable. A $49 tune-up trains customers to see you as a commodity. An $89-120 tune-up, performed thoroughly with a printed report, builds lasting loyalty.

The Tune-Up as a Sales Opportunity

A thorough tune-up generates repair and replacement opportunities. When a tech finds a failing capacitor, a cracked heat exchanger, or a refrigerant leak, that is a legitimate sales opportunity. Techs should document findings with photos, present them clearly, and give the customer a written estimate before leaving.
