How to clean Indoor AC Coils

How to Clean Indoor AC Coils                                                                                                                                                      If your air conditioner isn’t cooling like it used to, dirty indoor AC coils could be the culprit. Over time, dust, pet hair, and pollen build up on the  AC evaporator coil, reducing efficiency and increasing energy bills. At HVAC Paterson, the top-rated HVAC company in Paterson, New Jersey, we help homeowners keep their AC running at peak performance — and that starts with clean coils.

🔍 Why Cleaning Indoor AC Coils Matters

• Better Cooling Efficiency – Clean coils transfer heat more effectively.
• Lower Energy Bills – A dirty coil can increase cooling costs by up to 30%.
• Longer System Life – Prevents strain on your AC’s compressor.
• Improved Air Quality – Reduces dust, mold, and allergens in your home.

6 Steps on How to Clean Indoor AC Coils                                                                                                                                Safety First: Always turn off the AC unit at the thermostat and breaker before cleaning.
1. Locate the Indoor Unit

• The evaporator coil is inside the indoor air handler, typically in your basement, attic, or closet.

2. Remove the Access Panel

• Use a screwdriver to remove screws and carefully take off the panel.
• Some systems may have foil tape you’ll need to peel back.

3. Inspect the Coils

• Look for dirt, dust, and any signs of mold.
• If coils are heavily clogged, professional cleaning is recommended.

4. Dry Cleaning Method

• Use a soft brush or a vacuum with a soft-bristle attachment to gently remove loose debris.

5. Wet Cleaning Method

• Spray a no-rinse coil cleaner (available at hardware stores) evenly across the coils.
• Let it foam and break down dirt — the condensation will wash it away.

6. Reassemble the Unit

• Replace the panel securely and restore power to the unit.

🚫 Mistakes to Avoid

• Using high-pressure water — it can bend delicate coil fins.
• Harsh chemicals — they can damage the coil surface.
• Skipping filter changes — dirty filters quickly re-clog clean coils.
