A full diagnostic typically includes:
• Checking airflow throughout the home
• Inspecting the condenser and evaporator coils

During HVAC services Los Angeles, technicians will:
• Replace or upgrade air filters
• Recommend filter types based on where you live

Case scenario:
A Santa Monica homeowner noticed a musty smell indoors. The technician discovered trapped moisture inside the return duct, caused by coastal humidity. A simple duct seal and dehumidification adjustment solved the issue.
3. Professional Coil Cleaning
Dirty coils reduce airflow, lower efficiency, and make your system work harder than necessary.

• Measure refrigerant pressure
• Inspect for leaks
• Test cooling performance
• Recharge refrigerant safely if needed
Local insight:
Homes in Venice, Marina del Rey, and Long Beach experience higher corrosion rates due to salt air, making refrigerant leaks more common.
