Maintaining your heating and cooling system is essential for safety and efficiency, especially given the unique coastal climate here in San Francisco. A professional inspection ensures that your equipment remains reliable and complies with local safety standards.
A comprehensive HVAC inspection checklist includes:
- Thermostat and System Controls: We verify the settings, replace batteries, and confirm the system responds correctly to both heating and cooling modes. For smart models, we also check Wi-Fi connectivity and schedules.
- Air Filters and Return Vents: We inspect filters for clogs and ensure return registers are not blocked by furniture or debris. We recommend replacing filters every one to three months to maintain proper airflow.
- Evaporator Coil Cleaning: We check the indoor coils for dirt or microbial growth, which is common in our damp air. Cleaning these coils is vital for maintaining system efficiency and indoor air quality.
- Furnace Heat Exchanger Inspection: This is a critical safety step. We look for rust, corrosion, or hairline cracks that could lead to dangerous carbon monoxide leaks.
- Electrical Components: We examine wiring insulation, capacitors, and contactors for signs of wear, pitting, or overheating to prevent intermittent operation or motor failure.
- Outdoor Condenser Unit: We clear debris to ensure at least two feet of clearance and inspect the unit for corrosion caused by salt air, ensuring it remains level and the refrigerant lines are well-insulated.
- Safety Controls: We test flame sensors, limit switches, and carbon monoxide detectors to ensure your home remains protected.
If you notice unusual symptoms like weak airflow or loud banging and squealing noises, these are signs your system needs immediate professional attention. Regular inspections not only prevent expensive emergency repairs but can also help you qualify for valuable energy rebates.
