Hey Friends, It’s Samantha 👋
Your Amana 11,800 BTU 115 V Through-the-Wall Air Conditioner with Remote is installed, powered, and keeping your space blissfully cool. But to make sure it stays that way for years, a little regular maintenance goes a long way.
I’ve put together a simple, step-by-step maintenance checklist to keep your AC running efficiently, quietly, and safely all season. Let’s dive in!
1. Clean or Replace the Filter
Your filter is the first line of defense against dust, pollen, and pet hair.
-
Frequency: Every 2–4 weeks during heavy use.
-
Cleaning: Remove the filter, rinse with lukewarm water, and let it dry completely before reinstalling.
-
Replacement: Replace if damaged or excessively dirty.
A clean filter improves airflow and cooling efficiency, and prevents strain on the compressor. For more tips on filter maintenance, check Energy.gov’s guide.
2. Inspect the Sleeve and Seals
-
Exterior caulking: Check for cracks or gaps where air and moisture could leak. Reapply exterior-grade caulk if needed.
-
Interior seal: Ensure the unit sits snugly and that insulation or weatherstripping hasn’t shifted.
Proper sealing prevents heat infiltration and moisture problems, which can reduce efficiency and cause damage. P.C. Richard has a great visual guide for checking wall AC seals.
3. Check Drainage
Water drainage is crucial to prevent leaks and mold:
-
Tilt and placement: Ensure the sleeve remains slightly tilted outward.
-
Drain holes: Inspect for clogs and clean gently with a soft brush or compressed air.
-
Interior condensation: Wipe away any small puddles inside the unit.
Proper drainage keeps your AC running efficiently and prevents unwanted moisture damage. For more tips, see HVAC.com’s drainage maintenance advice.
4. Inspect Electrical Connections
Even if your AC is working fine, periodic checks are smart:
-
Dedicated outlet: Ensure it’s still clear of other devices.
-
Breaker: Confirm it hasn’t tripped or loosened over time.
-
Cords and plugs: Inspect for damage or wear.
Electrical safety keeps both your home and your AC unit protected.
5. Clean the Coils and Exterior
Dust and debris can reduce efficiency:
-
Exterior coil: Gently vacuum or brush dust off the fins.
-
Interior components: Wipe down accessible surfaces with a dry cloth.
Clean coils improve heat exchange and efficiency, so your AC cools faster and uses less energy. Energy.gov has an excellent guide on coil cleaning.
6. Test Operation and Remote Settings
-
Turn on the AC and test all modes: fan speeds, cooling, and timer functions.
-
Listen for unusual noises or vibration.
-
Adjust the remote settings as needed for optimal comfort.
Samantha’s Extra Tips 🌸
-
Take photos during seasonal checks for future reference.
-
Schedule a professional inspection every 2–3 years to catch issues early.
-
Keep a notebook of maintenance dates, filter changes, and observations.
