Top 5 AC Maintenance Tips to Keep Your Unit Efficient

Air conditioners are a lifeline during Kathmandu’s hot and humid months, but without proper care, they can lose efficiency, consume more energy, and fail prematurely. Regular maintenance ensures your AC works optimally, saves electricity, and provides cool, clean air all year round. Here are the top 5 AC maintenance tips every homeowner should follow.

1. Clean or Replace Air Filters Regularly

Air filters trap dust, pollen, and other particles, keeping the air in your home clean. Over time, filters get clogged, reducing airflow and forcing your AC to work harder.

Tip:

• Check filters every 2–4 weeks.
• Wash reusable filters with water and mild soap.
• Replace disposable filters as recommended by the manufacturer.

A clean filter improves air quality, enhances cooling efficiency, and lowers electricity consumption.

2. Keep the Outdoor Unit Free from Debris

The outdoor condenser unit is critical for heat exchange. Dust, leaves, and other debris can block airflow, reducing cooling efficiency.

Tip:

• Remove any plants, weeds, or debris within a 2–3 feet radius.
• Gently clean the fins with a soft brush or hose, avoiding high pressure that can bend the fins.

A well-maintained outdoor unit ensures your AC runs efficiently and prevents costly repairs.

3. Check and Clean the Coils

Both the evaporator and condenser coils can accumulate dirt over time, impacting heat absorption and release. Dirty coils increase energy consumption and reduce cooling capacity.

Tip:

• Inspect coils at least once a year.
• Carefully clean coils using a soft brush or coil cleaner solution.

Regular coil maintenance keeps your AC cooling effectively and prevents system strain.

4. Ensure Proper Refrigerant Levels

Refrigerant is essential for cooling. Low refrigerant levels not only reduce efficiency but can also damage the compressor.

Tip:

• Have a licensed technician check refrigerant levels annually.
• If low, repair leaks before refilling.

Maintaining proper refrigerant ensures your AC cools effectively while preventing high energy bills.

5. Schedule Professional AC Servicing

Even with regular DIY care, professional maintenance is crucial. Technicians can check electrical connections, lubricate moving parts, test system performance, and detect early problems.

Tip:

• Schedule servicing at least once a year before the peak summer season.

Professional servicing prolongs your AC’s lifespan, enhances performance, and reduces the risk of breakdowns during hot days.

Bonus Tip: Smart Usage Practices

• Set your thermostat to an optimal temperature (24–26°C) to save energy.
• Use ceiling fans or ventilation to reduce AC load.
• Avoid blocking vents with furniture or curtains.

Conclusion

Proper AC maintenance not only ensures cool, comfortable indoor air but also reduces electricity bills and extends your unit’s lifespan. By following these five essential tips — cleaning filters, maintaining outdoor units, checking coils, monitoring refrigerant, and scheduling professional servicing — you can keep your AC running efficiently all year long.

Stay cool, save energy, and protect your investment!
