What's Included in an HVAC Tune-Up? (Full Checklist)

An HVAC tune-up is a multi-point inspection and cleaning that keeps your system efficient, reliable, and safe. Here's exactly what a good technician checks — so you know what you're paying for.

AC / cooling tune-up checklist

• Check refrigerant charge and test for leaks
• Clean or inspect the condenser and evaporator coils
• Test the capacitor, contactor, and electrical connections
• Clear the condensate drain line and check the pan
• Inspect the blower motor and measure airflow
• Check the thermostat calibration and cycle
• Inspect/replace the air filter and tighten components

Heating / furnace tune-up checklist

• Inspect the burners and clean as needed
• Check the heat exchanger for cracks (a key safety step)
• Test the ignitor, flame sensor, and safety controls
• For gas systems, check for combustion and carbon-monoxide concerns
• Inspect the blower, belts, and electrical connections
• Verify thermostat operation and airflow

Why a tune-up is worth it

• Prevents breakdowns by catching small problems before they fail.
• Lowers bills — a clean, tuned system uses less energy.
• Protects safety — heat-exchanger and combustion checks guard against carbon monoxide.
• Extends lifespan and helps keep your manufacturer warranty valid.

What a tune-up costs — and how to save

A standalone precision tune-up runs about $89 per system. The easier (and cheaper) way to stay on top of it: a maintenance plan that includes two tune-ups a year plus priority service and repair discounts, starting at just $12/month. Over a year, the plan usually costs less than buying tune-ups separately — and you never have to remember to schedule them.

Frequently asked questions

What's included in an HVAC tune-up?

A multi-point inspection and cleaning: refrigerant and coils, electrical components, the condensate drain, blower and airflow, thermostat, filter, and - for heating - burners, heat exchanger, ignitor, and safety controls.

How much does an HVAC tune-up cost?

A standalone tune-up is about $89 per system. It's often cheaper to get it through a maintenance plan, which includes two tune-ups a year and starts at $12 per month with NC Climate Control.

How long does an HVAC tune-up take?

Usually about an hour per system, depending on its age and condition.

How often do I need an HVAC tune-up?

Twice a year is ideal - the AC in spring and the heating system in fall - so each is ready before its hardest-working season.

Is an HVAC tune-up really worth it?

Yes. It catches small issues before they become breakdowns, keeps efficiency (and bills) in check, protects safety, and helps keep your warranty valid.
