The No-BS AC Repair Checklist: What Your HVAC Technician Wishes You Knew Before Calling

Introduction

Let’s be real—when your AC stops working, panic sets in. You’re sweating, your house feels like an oven, and you’re frantically Googling “AC repair near me.” But here’s the thing: Not every AC issue requires a technician. Before you pick up the phone, there are a few things you should check.

This no-BS guide will walk you through what HVAC pros, like those at Olive Air and Heating, wish homeowners knew before making that service call. Let’s make sure you’re not wasting money on unnecessary repairs.

1. Check Your Thermostat

This sounds obvious, but you’d be surprised how many AC problems start with the thermostat. Before you assume your AC is broken:

• Make sure it’s set to “cool” and not just “fan”.
• Check the temperature setting—lower it by a few degrees to see if the system kicks in.
• Replace the batteries if it’s not hardwired.

If the thermostat isn’t working, your AC won’t turn on, no matter what else you do.

2. Look at Your Circuit Breaker

Sometimes, the problem isn’t your AC at all—it’s your electrical panel. If the breaker controlling your AC unit has tripped, your system won’t get power. Flip it back on and see if that solves the issue. If it trips again, there could be a bigger electrical problem that needs professional attention.

3. Inspect Your Air Filter

A dirty air filter is one of the most common (and avoidable) AC problems. A clogged filter restricts airflow, making your system work harder and overheat.

What to do:

• Check your filter every 30-60 days.
• If it looks dirty, replace it.
• If you have pets or live in a dusty area, you might need to change it more frequently.

A clean filter not only improves efficiency but also extends the life of your AC system.

4. Is Your Outdoor Unit Blocked?

Your AC’s outdoor unit (the condenser) needs space to breathe. If it’s surrounded by leaves, dirt, or debris, it can’t work efficiently. Here’s what to do:

• Make sure there’s at least two feet of clearance around the unit.
• Remove any grass, leaves, or dirt buildup.
• Hose it down gently to clear away dust.

Keeping your condenser clean can prevent overheating and improve airflow.

5. Check Your Vents

Blocked or closed vents can mess up your AC’s airflow. Walk through your home and:

• Make sure all vents are open.
• Remove any furniture, rugs, or objects blocking them.
• Clean dust and debris off vent covers.

Good airflow = better cooling. Simple.

6. Is Your AC Making Weird Noises?

Your AC isn’t supposed to sound like a rock concert. If you hear banging, grinding, or squealing, it’s a sign something’s wrong. Common causes include:

• Loose parts
• Motor issues
• Refrigerant leaks

If your AC is noisy, turn it off immediately and call the pros at Olive Air and Heating.

7. Are You Leaking Refrigerant?

If your AC is blowing warm air, refrigerant could be the culprit. Signs of a refrigerant leak include:

• Ice buildup on the evaporator coils
• Hissing sounds from the AC unit
• Higher energy bills (because your AC is working overtime)

Refrigerant issues require a professional—so if you suspect a leak, don’t DIY it. Call Olive Air and Heating right away.

8. Your AC Runs Non-Stop

Your AC shouldn’t be running 24/7. If it is, check:

• Your thermostat settings (is it set too low?)
• Your air filter (is it clogged?)
• Your home’s insulation (are windows and doors sealed?)

If none of these fix the issue, your AC might be undersized or struggling with a failing part.

9. Water Leaks Near Your AC

If you see water pooling around your indoor AC unit, don’t ignore it. The most common causes include:

• A clogged condensate drain line
• A frozen evaporator coil

Try unclogging the drain line with a wet/dry vacuum. If the issue persists, it’s time to call a pro.

10. Your AC Smells Bad

If your AC smells funky, here’s what it could mean:

• Musty smell? Mold or mildew in the ducts.
• Burning smell? Electrical issue—turn it off ASAP.
• Rotten egg smell? Could be a gas leak. Call a professional immediately.

HVAC Trivia: How Did People Stay Cool Before AC?

Before air conditioning, people used architecture and nature to stay cool. Buildings were designed with high ceilings, thick walls, and shaded courtyards to keep temperatures down. Fans and cross-ventilation were key. And believe it or not, people even stored large blocks of ice in their homes to cool the air—hence the term “icebox” for refrigerators!
