AC Repair Checklist
A young, motivated HVAC technician working on a heating and cooling system, representing a promising career path in a growing industry.

It’s the first 100-degree day of the summer. You’re ready to relax, crank up the AC, and let it do its thing. But then—bam—your cooling system conks out. Sound familiar?

Most people wait until their AC breaks down before taking action. By then, it’s an expensive repair or replacement job, and you’re stuck sweating it out while you wait for a technician.

What if you could stay ahead of those breakdowns?

This checklist is all about keeping your AC repair game strong—without stressing. By the end, you’ll know exactly what to do to keep your cooling system running smoothly.

1. Start With Regular Maintenance

Think of your AC like a car. Would you skip oil changes and then be shocked when the engine fails?

Regular maintenance is non-negotiable. Here’s what it should include:

  • Clean the filters. Dirty filters force your system to work overtime. Replace them every 1-3 months.
  • Inspect the coils. When coils get dusty, your AC’s efficiency tanks.
  • Check the refrigerant levels. Low refrigerant means your system isn’t cooling as it should.

These are easy, proactive steps that can save you hundreds on AC repair down the line.

2. Understand Your System

Know what type of AC system you have. Is it a central air system? A ductless mini-split? A window unit? Each has its quirks and maintenance needs.

For example, ductless mini-splits often need filter cleaning more frequently. Window units benefit from removing and cleaning the entire unit once a season.

Don’t overthink this. Just knowing the basics makes troubleshooting simpler.

3. Seal Your Home’s Air Leaks

Why make your AC work harder than it needs to?

Leaks around windows, doors, and ductwork force your system to run longer to cool your home.

Quick fixes include:

  • Sealing ductwork with foil tape or mastic sealant.
  • Adding weatherstripping to windows and doors.
  • Using caulk to seal any gaps or cracks.

Less strain on your AC means fewer repair calls—and that’s the goal, right?

4. Invest in a Programmable Thermostat

A programmable thermostat isn’t just convenient. It’s a long-term AC repair prevention tool.

Set it to adjust the temperature when you’re not home. This reduces wear and tear on your system.

For example, let’s say you’re gone from 9 to 5. Set the thermostat to 78 degrees during those hours and drop it back to 72 before you return.

Smart thermostats like Nest or Ecobee even send alerts when your system isn’t running efficiently—a heads-up before you need an emergency AC repair.

5. Watch for Early Warning Signs

Your AC usually tells you when it’s struggling. The trick is catching these signs early:

  • Uneven cooling: Some rooms are ice-cold, while others feel like a sauna.
  • Weird noises: Grinding, squealing, or banging noises? Not normal.
  • Higher energy bills: A sudden spike could mean your system is overworking.
  • Bad odors: Musty or burnt smells need immediate attention.

If you catch these signs early, the AC repair process is faster and cheaper.

6. Don’t DIY Beyond Your Skill Level

Look, I get it. You want to save money. But messing with your AC’s electrical components or refrigerant can turn a small problem into a big one.

Here’s where I draw the line:

  • Cleaning filters? Go for it.
  • Checking for air leaks? Absolutely.
  • Adding refrigerant? Call a pro.

Look for energy-efficient models to lower utility costs. Bonus: Many of these qualify for tax credits and rebates.
