In the scorching heat of Texas, a well-functioning air conditioner is not just a luxury; it's a necessity. To ensure your AC unit stays in top shape, regular DIY upkeep is essential. In this comprehensive guide, we'll explore practical do-it-yourself air conditioner maintenance tips, empowering you to keep your cool during the hottest days. Additionally, we'll discuss when it's time to call in the professionals for expert assistance.

DIY Air Conditioner Upkeep Tips

Air filters play a crucial role in maintaining airflow and indoor air quality. Check your filters monthly and replace them every 1-3 months, or more frequently if you have pets or suffer from allergies. Over time, dust and debris can accumulate on the evaporator and condenser coils, hindering the heat exchange process. Clean these coils annually using a soft brush or vacuum cleaner, ensuring optimal efficiency.

The outdoor condenser unit needs adequate airflow to function efficiently. Regularly clear any leaves, grass, or debris around the unit to prevent airflow obstruction and potential damage. A clogged drain line can lead to water damage and reduced efficiency. Inspect the drain line for clogs and clean it using a mixture of bleach and water to prevent algae and mold growth.

Ensure your thermostat is set to your desired temperature. Consider upgrading to a programmable thermostat for energy efficiency, allowing you to adjust temperatures based on your daily schedule. Leaks in your ductwork can result in cooled air escaping before reaching its destination. Inspect ducts for visible leaks and seal them with duct tape or call a professional for more extensive repairs.

Low refrigerant levels can impact your AC's performance. If you notice reduced cooling capacity or warm air blowing, consult a professional to check and replenish refrigerant levels. Keep your air conditioner's moving parts, such as the fan and motor, well-lubricated. This simple step can prevent friction, reduce wear and tear, and extend the lifespan of your unit. Adequate insulation ensures your home stays cool without overworking the AC. Check and improve insulation in your attic and walls to minimize heat transfer and maximize energy efficiency.

When to Call Professionals

While DIY maintenance is crucial, there are instances when it's prudent to seek professional help. If your air conditioner starts making unusual noises or emitting strange odors, it could indicate underlying issues. Professional technicians can diagnose and address these problems effectively.

If your AC isn't cooling your home as it should, it's time to call in professionals like the experts at McWillams Heating, Cooling and Plumbing. This could be due to refrigerant issues, compressor problems, or other complex issues that require expert attention. If your AC is turning on and off too frequently, or if it's running for only short periods, it may indicate a malfunction. Professional technicians can diagnose and repair issues with the thermostat, sensors, or other components.

Excessive water leakage around your indoor unit suggests a problem with the drainage system. Professional technicians can identify and fix the issue to prevent water damage and maintain optimal performance. If you notice electrical problems, such as tripped circuit breakers or exposed wires, it's essential to call professionals immediately to prevent safety hazards.


In the relentless heat of Texas, a well-maintained air conditioner is your best ally for staying comfortable. Regular DIY upkeep, combined with professional assistance when needed, ensures that your AC unit operates efficiently, keeping your home cool and your energy bills in check. By following these DIY tips and knowing when to call in the experts, you'll be well-prepared to face the hot Texas summers with confidence and comfort.
