How To Clean AC Evaporator Coils Inside Your House: Guide

How to Clean AC Evaporator Coils Inside Your House (Without Losing Your Cool)

Let’s be real—nobody daydreams about spending a Saturday afternoon elbow-deep in their AC unit, scrubbing grime off evaporator coils. But here’s the kicker: if we ignore these sneaky little coils, our AC might just quit on us mid-heatwave. And trust us, sweating through a Pittsburgh summer without AC is about as fun as watching paint dry. Lucky for you, we’ve got the ultimate guide to cleaning those coils and keeping your sanity intact. (FYI, if you’d rather leave the dirty work to pros, our team at Clean Air Duct here in Pittsburgh lives for this stuff. Just sayin’.)


Why Clean Evaporator Coils Matter (Spoiler: It’s Not Just About Cold Air)

Ever wonder why your AC sounds like it’s gasping for breath after a few years? Blame the evaporator coils. These coils are like the lungs of your AC system—they absorb heat from your home’s air, cooling it before recirculating. But over time, dust, pet hair, and mystery gunk (seriously, where does it all come from?) cling to the coils, forcing your AC to work harder. The result? Higher energy bills, lukewarm air, and a shorter lifespan for your unit.

Here’s what happens when you neglect them:

  • Energy bills spike by up to 30% (ouch).
  • Your AC might freeze up like a popsicle.
  • Mold or bacteria can hitch a ride on the coils, spreading funky smells.

Not exactly a vibe. But don’t panic—we’ll walk you through the cleanup.


Step-by-Step Guide to Cleaning Your Evaporator Coils

Before We Start:

  • Turn off the power to your AC. (Seriously. We like you alive.)
  • Grab gloves, a soft brush, coil cleaner spray, and a vacuum.

Step 1: Locate the Evaporator Coils

Your coils live inside the air handler, usually in the attic, basement, or a closet. Remove the access panel (check your manual if it’s playing hide-and-seek).

Step 2: Vacuum Loose Debris

Use a brush attachment to suck up dust bunnies and cobwebs. Think of it as a spa day for your AC.

Step 3: Spray Coil Cleaner

Apply a foaming coil cleaner (we like non-acidic options). Let it sit for 5–10 minutes to dissolve grime.

Step 4: Rinse Gently

Use a spray bottle with water to rinse. Avoid high-pressure hoses—you’re cleaning coils, not power-washing a driveway.

Step 5: Reassemble & Test

Dry everything, close the panel, and restore power. Crank the AC and bask in your victory.


DIY vs. Professional Cleaning: Which Wins?

Sure, DIY saves money upfront, but let’s be honest: most of us aren’t HVAC whisperers. Here’s the breakdown:

Cost $20–$50 (supplies) $100–$300 (depending on labor)

4 Burning Questions About Evaporator Coils (Answered)

1. How often should I clean my evaporator coils?
Aim for once a year. If you have pets or live in a dusty area, bump it to twice.

2. Can dirty coils increase my energy bill?
Absolutely. Clogged coils force your AC to run longer, hiking up the cost of cooling.

3. Is coil cleaner safe to use?
Most are, but always wear gloves and ventilate the area. When in doubt, ask a pro (like us!).
