Why AC Tune-Up Matters More in Indiana

When you’re enjoying summer vacation in Indiana, your air conditioner is working hard to keep you cool. Frequent heatwaves, increasing energy costs, and high humidity put heavy loads on cooling systems, but a professional AC unit tune-up prepares your system for the summer, minimizing the risk of breakdowns while keeping your comfort high and your energy and repair bills low.

Why Indiana Homeowners Need Regular AC Maintenance

Regular maintenance keeps your AC working at peak performance, even in Indiana’s most demanding summer conditions.

Hot and humid summers

Indiana summers are humid and intense, with temperatures often exceeding 90 degrees. Humidity makes the heat feel more intense than your thermostat says, and homeowners often set their thermostats to cooler temperatures to offset these effects, putting their AC systems under a heavier load.

AC components may wear out or become dirty without adequate maintenance, reducing cooling performance and increasing the risk of breakdowns, especially under more demanding Indiana conditions. Routine maintenance helps identify and correct wear and prepares your system for the heat of Indiana summers.

Increasing energy rates and cooling efficiency

With AES Indiana intending to raise energy rates starting in 2026, Indiana residents may pay up to 20% more for their cooling during the summer, further stressing the importance of an energy-efficient AC system. Well-maintained ACs cool more effectively with less energy, potentially translating to significantly lower utility bills during peak summer months.

Improving system longevity

Indiana’s environment introduces dust, pollen, moisture, and other debris to your AC system. These airborne contaminants build up inside your unit, including on coils, filters, and fan motors, increasing friction and accelerating wear on components.

Routine AC cleaning and inspection address inefficiencies before they escalate and prevent problems such as burnt-out motors, coil corrosion, or overheating compressors. Seasonal tune-ups help prolong the operating lifespan of your AC, without well-maintained units often outlasting neglected units by several years and delaying the need for system replacement.

Indoor air quality

A combination of high heat, smog, elevated pollen levels, and stagnant air during Indiana summers can impact indoor air quality. Without regular filter changes and cleaning, your air conditioner may recirculate contaminants such as pollen, mold spores, and dust rather than filtering them out. This can trigger allergy symptoms or worsen indoor air for households with asthma or other respiratory conditions.

AC maintenance optimizes airflow and filtering so your system can better regulate indoor air quality. With better indoor air quality, households often experience reduced allergy symptoms and lower risk of respiratory issues associated with airborne particles.

Avoiding emergency repairs

Seasonal storms, heatwaves, and high humidity strain cooling systems, and many emergency breakdowns are the result of these conditions pushing AC components past their limit. In many cases, these components had pre-existing problems that a technician could have spotted and addressed during a tune-up, preventing them from failing just when you need your AC most.

What’s Included in a Professional AC Unit Tune-Up?

An AC tune-up is a standardized service that provides comprehensive inspections, cleaning, tests, and adjustments. At Dugan Air, our HVAC technicians adhere to a thorough process to address underlying inefficiencies and optimize AC performance.

A professional tune-up typically includes these tasks:

• Checking refrigerant level and pressure, and testing for leaks
• Cleaning and inspecting the evaporator and condenser coils to optimize heat transfer
• Replacing the air filter
• Testing the thermostat and recalibrating if necessary
• Measuring airflow and inspecting ductwork for leaks
• Tightening electrical connections
• Inspecting the capacitor, contactor, and other electrical components
• Cleaning the condensate drain and checking for clogs

How Often Should You Tune Up Your AC in Indiana?

Most Indiana households should plan for annual AC tune-ups. Ideally, schedule services in the early spring, between March and May, to correct any issues or inefficiencies before summer temperatures arrive. All cooling system types benefit from annual maintenance, including central air conditioners, ductless mini-splits, and heat pumps.

In some cases, your system may need service ahead of schedule. Look for these signs:

• Unusual noises during operation, such as buzzing or grinding
• Frequent cycling
• Uneven temperature distribution
• Warm or weak air from the vents
• High humidity or poor indoor air quality
• A spike in energy bills without a change in usage patterns
