What to Expect During a Professional AC Tune-Up

The Outdoor Unit Inspection

Our technician starts with your condenser unit outside:

• Clean the condenser coil — Dirt and debris on the coil reduce heat transfer, forcing your system to work harder
• Check refrigerant levels — Too much or too little refrigerant reduces efficiency and can damage the compressor
• Inspect the fan motor and blade — Worn bearings or a damaged blade reduce airflow
• Check electrical connections — Loose connections cause heat buildup and potential failure
• Test the capacitor — A weak capacitor can cause hard starting, which stresses the compressor
• Clear debris from around the unit and ensure adequate clearance

The Indoor Unit Inspection

Next, the technician moves inside to your air handler:

• Inspect and clean the evaporator coil — A dirty evaporator coil reduces cooling capacity and dehumidification
• Check the blower motor and wheel — Dirty or sluggish blowers reduce airflow throughout your home
• Inspect the drain line and pan — A clogged drain line can cause water damage and mold growth
• Test safety controls — These protect your system and home from dangerous conditions
• Check the air filter — And recommend the right replacement schedule

System Performance Testing

Finally, the technician evaluates overall system performance:

• Measure supply and return temperatures — The temperature difference (delta-T) should be 15-20°F
• Check airflow at key registers to ensure balanced distribution
• Calibrate the thermostat to ensure accurate temperature readings
• Test the system through a full cooling cycle to verify proper operation
• Document findings and flag anything that needs attention

Why Annual Tune-Ups Matter

A properly maintained system runs more efficiently (saving 10-20% on energy costs), breaks down less frequently, and lasts years longer than a neglected one. In Central Florida, where your AC works harder than almost anywhere in the country, that annual tune-up pays for itself many times over.
