An HVAC tune-up includes inspecting and cleaning the condenser and evaporator coils, checking refrigerant levels and pressures, testing electrical connections and capacitors, lubricating moving parts, inspecting the heat exchanger for cracks, replacing the air filter, calibrating the thermostat, and verifying system performance. Regular maintenance extends equipment life by 5-10 years and prevents costly breakdowns. This estimate covers both AC and furnace tune-ups for NorCal homeowners.

Sacramento's long cooling season (May through October) puts heavy demands on your AC system. Spring maintenance ensures your system is running at peak efficiency before triple-digit temperatures arrive.

San Luis Obispo is located in San Luis Obispo County (Central Coast). Charming college town (Cal Poly) with a mix of historic adobes, bungalows, and newer homes. The local utility provider is PG&E.

HVAC Tune-Up & Maintenance in San Luis Obispo — FAQ

How often should I schedule HVAC maintenance?+

Schedule maintenance twice per year: a cooling tune-up in spring (March-April) before Sacramento's hot season, and a heating tune-up in fall (September-October) before winter. This ensures your system is ready for each season's demands.

What happens if I skip annual maintenance?+

Skipping maintenance reduces efficiency by 5-10% per year, increases the risk of unexpected breakdowns (often during the hottest or coldest days), and can void manufacturer warranties. Over time, neglected systems fail 5-8 years earlier than maintained ones.

Does HVAC maintenance really save money?+

Yes. A $150-$250 tune-up typically saves $100-$200 annually in energy costs and prevents $500-$2,000+ emergency repair bills. It also extends the life of equipment worth $5,000-$15,000.

What should I do between professional tune-ups?+

Change your air filter every 1-3 months, keep 2 feet of clearance around your outdoor unit, rinse the condenser coil with a garden hose monthly in summer, and keep supply registers unobstructed.
