DIY Servicing: Basic Maintenance Tasks You Can Do

Before we delve into the more complex servicing procedures, let’s start with some basic maintenance tasks you can easily perform yourself.
1. Cleaning the Air Filter:

• Frequency: Every 1-2 months, or more often if you live in a dusty environment.
• Procedure:
• Locate the air filter, usually behind the front panel of the indoor unit.
• Remove the filter and gently vacuum it with a brush attachment.
• If the filter is heavily soiled, wash it with mild detergent and water.
• Allow the filter to dry completely before reinstalling it.

2. Cleaning the Evaporator Coils:

• Frequency: Once a year, or more often if the coils are visibly dirty.
• Procedure:
• Turn off the air conditioner and unplug it from the power source.
• Remove the front panel of the indoor unit to access the evaporator coils.
• Use a soft brush or vacuum cleaner with a brush attachment to gently clean the coils.
• Avoid using harsh chemicals or abrasive cleaners that could damage the coils.

3. Checking the Refrigerant Levels:

• Frequency: Every 2-3 years, or if you suspect a refrigerant leak.
• Procedure:
• This task requires specialized equipment and expertise. It’s best to contact a qualified HVAC technician for this service.

Professional Servicing: When to Call an Expert

While some basic maintenance tasks can be done yourself, certain servicing procedures require the expertise of a qualified HVAC technician. Here are some situations where it’s best to call in a professional:

• Refrigerant Recharge: Refrigerant leaks are a common issue that requires professional diagnosis and repair.
