In Van Nuys, air conditioning is more than a convenience—it’s a necessity. With high temperatures common for much of the year, your AC unit works hard to keep your home comfortable. However, without regular maintenance, your system may lose efficiency, consume more energy, or break down unexpectedly.
To help avoid costly repairs and ensure optimal performance, it’s essential to know how to do basic air conditioner maintenance. This guide outlines simple tasks homeowners can handle and explains when to call professionals. For comprehensive care, expert air conditioning services in Van Nuys are always available to support your system’s needs.
🔧 How to Do a Filter Replacement
Why it matters: A clean filter improves airflow and helps your system operate efficiently.
Steps to follow:
- Turn off your system.
- Locate the air filter in your return vent or air handler.
- Remove the old filter and check its size.
- Insert a new filter in the correct direction.
- Replace every 30–90 days.
🔧 How to Do a Visual Inspection
Why it matters: Spotting early issues helps prevent serious breakdowns.
Steps to follow:
- Look for signs of damage, rust, or loose connections.
- Listen for unusual noises when the system runs.
- Check for water around the indoor unit (a clogged drain line).
- Inspect the outdoor unit for debris or bent fins.
🔧 How to Do Coil Cleaning
Why it matters: Dirty coils reduce the unit’s ability to absorb and release heat.
Steps to follow:
- Turn off the power supply to the unit.
- Gently clean the indoor evaporator coil with a soft brush or a no-rinse coil cleaner.
- For the outdoor condenser coil, remove debris and rinse with a low-pressure hose from the inside out.
- Let the coils dry before restoring power.
🔧 How to Do Condensate Drain Maintenance
Why it matters: A blocked drain line can lead to leaks and water damage.
Steps to follow:
- Locate the drain line (usually a white PVC pipe near your indoor unit).
- Use a wet/dry vacuum to clear the line, or pour in a cup of vinegar to prevent clogs.
- Repeat every few months to avoid buildup.
🔧 How to Do a Thermostat Test
Why it matters: Inaccurate settings can lead to unnecessary cooling or energy waste.
Steps to follow:
- Set your thermostat to “cool” and lower the temperature.
- Wait to see if the system starts and cools the space.
- If it fails to respond, check the batteries or replace the thermostat if needed.
