What Does an AC Tune-Up Service Include?

Spring is one of the best times to prepare your air conditioner for warmer weather. For homeowners in Northern Indiana and Southwest Michigan, an AC tune-up helps make sure your cooling system is clean, efficient, and ready before peak summer temperatures arrive.

A professional AC tune-up includes a series of inspections, cleanings, tests, and adjustments designed to improve performance and reduce the risk of unexpected breakdowns. Below, we’ll explain what is included in an AC tune-up, how long it usually takes, and when to schedule service.

What Is an AC Tune-Up?

An AC tune-up is a preventive maintenance visit where a technician inspects, cleans, tests, and adjusts key parts of your air conditioning system. The goal is to help your AC run more efficiently, catch small issues early, and reduce the chances of a breakdown during hot weather.

What Does an AC Tune-Up Include?

An AC tune-up typically includes a detailed inspection of the indoor and outdoor components of your cooling system. Your technician will check system performance, clean key components, test electrical parts, look for signs of wear, and review any recommended repairs or maintenance needs before leaving.

Common AC tune-up tasks include:

• Condenser Unit Inspection and Coil Cleaning: Inspect the outdoor condenser for wear, debris, and airflow restrictions while cleaning coils to improve heat transfer and cooling efficiency.
• Refrigerant Level and Leak Check: Measure refrigerant charge, test operating pressures, and inspect for leaks or damaged refrigerant line insulation.
• Condensate Drain Cleaning and Testing: Clear and test the drain line to help prevent clogs, water overflow, and moisture damage.
• Thermostat Testing and Calibration: Verify accurate temperature readings, proper communication, and thermostat settings.
• Electrical Component Inspection and Tightening: Inspect wiring, contactors, relays, and capacitors while tightening loose electrical connections for safer operation.
• Voltage and Amperage Testing: Measure electrical draw on motors and components to identify strain or failing parts.
• Blower Motor and Indoor Fan Inspection: Inspect the blower motor and fan assembly for wear, balance, and proper airflow performance.
• Airflow Performance and Temperature Split Testing: Check vent airflow and measure the temperature difference between return and supply air.
• Air Filter Inspection or Replacement: Inspect the filter for buildup and replace it if needed to maintain airflow and indoor air quality.
• Evaporator Coil Inspection and Cleaning: Clean the indoor evaporator coil when accessible to improve cooling performance and efficiency.
• Compressor and Condenser Fan Testing: Test compressor startup/run cycles and inspect the condenser fan motor and blades for reliable operation.
• Ductwork and Control Safety Inspection: Inspect visible ductwork for leaks or restrictions and verify proper operation of controls and safety switches.
• Lubrication of Moving Parts: Lubricate serviceable components where applicable to reduce friction and wear.

How Long Does an AC Tune-Up Take?

Most AC tune-ups take about 1.5 to 2 hours. The exact timing depends on the condition of your system, how easy the equipment is to access, and whether the technician finds any issues that need closer inspection.

If your system has not been maintained in several years, has heavy dirt or debris buildup, or requires additional testing, the appointment may take longer.

Is an AC Tune-Up Worth It?

Regular tune-ups prevent issues and create a more comfortable, dependable home. Specifically, tune-ups help your system run efficiently, lower energy costs, improve comfort, and extend the life of your equipment. They improve your AC's overall performance.

Tune-ups also work to improve your home’s safety and your personal savings.

• Safety: Techs inspect and test your furnace to confirm it is operating properly. This includes checking for carbon monoxide leaks, a colorless and odorless gas that is dangerous to residents and pets.
• Savings: Routine furnace maintenance can help you save money over time. Small problems are identified early and corrected before they become expensive repairs or emergency breakdowns.

What an AC Tune-Up Does Not Include

While technicians may find issues during routine maintenance, major repairs or replacement recommendations are separate from standard tune-up work. Your technician will discuss any recommended repairs, and you can schedule that service for a later date.

When to Schedule AC Tune-Up Services

Spring is the ideal time for a tune-up, but regular annual maintenance matters most. As long as your AC is being serviced once a year, then you’re setting your household up for success.
