🛠 Tools & Supplies You’ll Need

✔ Garden hose with a spray nozzle (DO NOT use a pressure washer – too strong!)
✔ Screwdriver or wrench (to remove the fan grill)
✔ Soft brush or fin comb (optional, for coil cleaning)
✔ Coil cleaner spray (optional, for deep cleaning)
✔ Gloves & safety glasses (optional, for protection)

🚀 Step-by-Step Guide to Cleaning Your AC Condenser

1️⃣ Turn Off the Power (IMPORTANT ⚠️)

  • Find the AC disconnect box near the unit and switch it OFF.
  • If you don’t see a switch, turn off the breaker in your electrical panel.
  • Safety first! Never clean an AC unit while it’s powered on.

2️⃣ Remove Debris Around the Unit

  • Clear leaves, dirt, and sticks from around the condenser.
  • Keep at least 2 feet of space around the unit for proper airflow.

3️⃣ Remove the Fan Cover & Top Grill

  • Use a screwdriver or wrench to loosen the screws on the top grill.
  • Lift the fan carefully (DO NOT pull the wires!) and set it aside.
  • Use a vacuum or brush to remove dirt & leaves inside the unit.

4️⃣ Spray the Coils with Water (Inside Out Method)

💧 DO NOT use a pressure washer—it can bend the fins!

  • Insert the hose inside the unit and spray outward.
  • This pushes dirt out rather than deeper into the coils.
  • Use a gentle spray setting to avoid bending the coil fins.

5️⃣ Apply Coil Cleaner (Optional for Deep Cleaning)

  • If the coils are very dirty, apply an AC coil cleaner spray.
  • Let it sit for 5-10 minutes (follow product instructions).
  • Rinse it off thoroughly with the hose.

6️⃣ Straighten Bent Fins (If Needed)

  • If you notice bent fins, use a fin comb or a butter knife to straighten them.
  • This helps improve airflow.

7️⃣ Reassemble & Restore Power

  • Reattach the fan and top grill.
  • Turn the breaker or disconnect switch back ON.
  • Let the unit run normally and check if it’s working properly.

✅ Bonus Tips to Keep Your AC Clean

✔ Clean your condenser at least twice a year (spring & fall).
✔ Trim bushes and grass around the unit for proper airflow.
✔ Cover the unit in winter to prevent debris buildup.
✔ Check for refrigerant leaks if the unit isn’t cooling properly.

🔎 When to Call a Professional?

❌ If your AC still doesn’t cool properly after cleaning.
❌ If you notice ice buildup or refrigerant leaks.
❌ If the fan motor is making loud noises or isn’t spinning.
