For homeowners looking to tackle minor air conditioning maintenance and repairs, here are some handy DIY tips from the experts at High Performance Heating & Air Conditioning:

Clean or Replace Air Filters

1. Locate the air filter(s) in your HVAC system, typically behind return air grilles or in the air handler.
2. Check the manufacturer’s recommendations for frequency of cleaning or replacement.
3. For disposable filters, simply replace them with new ones of the same size and type.
4. For reusable filters, use a vacuum or brush to remove dirt and debris, and consider washing them with mild soap and water.

Clear Outdoor Unit

1. Shut off power to the air conditioning unit at the circuit breaker or disconnect box.
2. Remove any debris, such as leaves or twigs, from the unit’s exterior and surrounding area.
3. Use a soft brush or vacuum attachment to gently clean the condenser coils.
4. Ensure there is at least two feet of clearance around the unit for proper airflow.

Check Refrigerant Levels

While refrigerant levels should only be handled by professionals, you can:

1. Locate the refrigerant line(s) between the indoor and outdoor units.
2. Feel the lines – if the larger, insulated line is warm and the smaller line is cool, the refrigerant levels are likely adequate.
3. If both lines are warm or cool, this may indicate a refrigerant leak or other issue requiring professional attention.

Inspect Electrical Components

1. Ensure the unit’s disconnect box is securely closed and clear of any obstructions.
2. Check for any frayed or damaged wiring, and have a professional address any issues.
3. Clean any dust or debris from electrical components using a soft brush or compressed air.

Remember, while these DIY tips can help maintain your AC system, it’s always best to consult a professional at High Performance Heating & Air Conditioning for major repairs or installations to ensure safety and optimal performance.
