🩺 Why Maintenance Matters
✅ Maintains high SEER and HSPF efficiency levels.
✅ Prevents mold and bacteria buildup in filters and coils.
✅ Helps avoid water leaks from clogged drain lines.
✅ Extends system lifespan (15-20 years with regular care).
✅ Keeps warranties valid (many manufacturers require documented maintenance).
🧽 Cleaning Filters: A Step-by-Step Guide
1️⃣ Turn off the system. 2️⃣ Open the front panel of the indoor unit. 3️⃣ Remove the air filters. 4️⃣ Vacuum dust and debris or wash with warm, soapy water. 5️⃣ Let filters dry completely. 6️⃣ Reinstall and close the panel.
Do this monthly in high-use seasons (summer and winter). Clean filters improve airflow, reduce strain on your system, and maintain clean indoor air.

🌀 Cleaning Coils and Blower Wheels
Over time, coils and blower wheels can accumulate dust and grime, reducing efficiency and airflow.
✅ Indoor Unit Coils:
-
Use a soft brush attachment on a vacuum.
-
For heavy grime, a coil cleaner may be used (follow product instructions).
✅ Blower Wheels:
-
Accessible in some models by removing the cover.
-
Professional cleaning recommended if buildup is significant.
Cleaning these components once or twice a year ensures your system operates quietly and efficiently.

💧 Checking the Condensate Drain Line
Clogged drain lines can lead to water leaks and water damage.
✅ Check for clear water drainage when the system is running.
✅ Use a wet/dry vacuum on the drain line if clogs occur.
✅ Pour a small amount of vinegar solution through the line to prevent algae buildup (consult your manual).
Regular checks, especially during humid seasons, can prevent leaks and mold growth.
