Maintaining your air conditioning unit is essential for ensuring efficient operation and extending its lifespan. While it’s always recommended to call a professional air conditioning company, such as TRS Cooling, for regular assessments and servicing, there are several steps you can take on your own to keep your system in good working order between service visits.

Key Takeaways
- Regular professional maintenance by TRS Cooling is crucial for optimal performance.
- Simple maintenance can enhance efficiency and prevent major issues.
- Keeping the area around your AC unit clear and filters clean can significantly improve your AC’s performance.
1. Check and Clean the Filters Regularly
Why It’s Important: Dirty or clogged filters can reduce the efficiency of your AC unit, causing it to work harder to cool your space. This can lead to increased energy consumption and potential damage over time.
How to Do It
- Locate the Filters: Filters are usually found in the indoor unit or within the return air duct.
- Remove the Filters: Carefully remove the filters following the manufacturer’s instructions.
- Clean the Filters: If the filters are reusable, rinse them under lukewarm water. Use a mild detergent if they are particularly dirty. Ensure they are completely dry before reinstalling.
- Replace if Necessary: If the filters are disposable or too dirty to clean, replace them with new ones.

Tip: Clean or replace your filters every one to two months, especially during peak usage seasons.
2. Keep the Area Around the Outside Unit Clear
Why It’s Important: The outdoor unit (condenser) needs adequate airflow to function efficiently. Debris such as leaves, dirt, and grass can obstruct airflow and cause the unit to overheat.
How to Do It
- Inspect the Area: Regularly check around the outdoor unit for any obstructions.
- Clear Debris: Remove any leaves, grass clippings, or other debris that may have accumulated around the unit.
- Trim Vegetation: Keep bushes, plants, and grass trimmed back at least two feet from all sides of the unit.
Tip: Perform these checks monthly and after any severe weather conditions.
3. Inspect the Temperature Settings
Why It’s Important: Improperly set temperature can lead to inefficiency and discomfort. Ensuring your thermostat is set correctly can help maintain a comfortable temperature and reduce energy usage.
How to Do It
- Check the Settings: Ensure the temperature is set to a desired setting and mode (cooling, heating, or auto).
- Calibrate if Necessary: If the temperature displayed seems inaccurate, you might need to recalibrate your thermostat. Refer to the manufacturer’s manual for instructions.

Tip: Consider upgrading to a programmable thermostat to better control your home’s temperature and energy usage.
4. Check the Refrigerant Levels
Why It’s Important: Proper refrigerant levels are essential for your AC unit to cool effectively. Low levels can indicate a leak or other issues that need professional attention.
How to Do It
- Inspect for Signs of Low Refrigerant: Listen for hissing sounds near the AC unit or check for ice buildup on the refrigerant lines.
- Call a Professional: If you suspect low refrigerant levels, contact TRS Cooling for a thorough inspection and potential refill.
Tip: Regular servicing by professionals can prevent refrigerant issues and keep your unit running smoothly.
5. Clean the Coils
Why It’s Important: The evaporator and condenser coils in your AC unit can accumulate dirt over time, reducing efficiency and potentially causing system failure.
How to Do It:

- Turn Off the Power: Always turn off the power to your AC unit before performing any maintenance.
- Clean the Coils: Use a soft brush to remove dirt and debris from the coils. For a more thorough cleaning, you can use a coil cleaner spray.
- Inspect the Coils: Look for signs of damage or corrosion and contact a professional if you notice any issues.
Tip: Clean the coils at least once a year to maintain optimal efficiency.
