A ROVSUN split air conditioner is a reliable choice for home and office cooling, but regular cleaning is key to maintaining its efficiency and air quality. Dust, mold, and debris build up in both indoor and outdoor ROVSUN units, increasing energy use by up to 30%, causing odors, and circulating allergens. You can clean your ROVSUN split AC yourself with basic tools—this guide simplifies the process to focus on essential steps, ensuring your ROVSUN unit runs smoothly.
Tools You’ll Need
Gather these items before starting: rubber gloves, face mask, microfiber cloths, soft-bristled brush, vacuum with brush attachment, mild detergent, white vinegar, spray bottle, bucket, screwdriver (if needed), and a plastic sheet to protect surfaces.
Safety Precautions
Always turn off the power to your ROVSUN AC at the circuit breaker and unplug the indoor unit. Let the unit cool for 1–2 hours, avoid harsh chemicals, and handle delicate coils gently to prevent damage.
Step 1: Clean the ROVSUN Indoor Unit

1.1 Clean the Air Filter
Open the front panel of your ROVSUN indoor unit (pull the side tabs) and remove the filter. Vacuum loose dust, then soak reusable filters in warm soapy water for 10 minutes, scrub gently, rinse, and air-dry completely. Replace disposable filters with new ones of the correct size for ROVSUN models.
1.2 Clean the Front Panel and Vents
Wipe the ROVSUN front panel with a damp cloth and mild soap. Use a vacuum or soft brush to clean the air vents and louvers, wiping with a vinegar-water mix to remove mold. Dry the panel before reattaching.
1.3 Clean the Evaporator Coil and Drain Pan
With the filter and panel removed, vacuum the evaporator coil (behind the filter) gently. Spray with a 50/50 vinegar-water mix, let sit 10 minutes, and wipe excess moisture. Clean the drain pan below with vinegar to kill mold and clear the drain hole with a pipe cleaner to prevent leaks.
1.4 Reassemble
Once dry, reinsert the filter (align the airflow arrow toward the unit) and close the front panel securely.
Step 2: Clean the ROVSUN Outdoor Unit

Clear debris (leaves, grass) around the ROVSUN outdoor condenser, leaving 2–3 feet of space. Vacuum the grille and condenser coil, then rinse gently with a garden hose (low pressure) from the inside out. Avoid spraying the fan motor. Wipe the fan blades and straighten bent fins with a fin comb if needed.
Step 3: Test Your ROVSUN AC
Turn the power back on, set your ROVSUN AC to cooling mode (5–10°F below room temp), and check for cold air flow. Listen for unusual noises and ensure no water leaks from the indoor unit.
Maintenance Tips
Clean ROVSUN filters every 1–2 months, deep clean both units twice a year, and cover the outdoor unit in off-seasons. Schedule annual professional service for optimal performance.
Regular cleaning keeps your ROVSUN split AC efficient, extends its lifespan, and ensures clean air. Follow these simple steps to keep your ROVSUN unit in top condition year-round.
