Get answers to common questions about hvac services in San Luis Obispo, California.
For a standard residential system, full replacement typically ranges from $6,500 to $12,000+. This range accounts for our local labor costs, the higher-efficiency units recommended for our climate, and potential complexities like older ductwork in historic homes. The final price depends heavily on system size (tonnage), brand, efficiency rating (SEER), and any necessary ancillary work like duct modifications or electrical upgrades.
The ideal times are during our mild shoulder seasons—late spring (April-May) or early fall (September-October). Scheduling service during these periods avoids the peak summer demand when HVAC companies are busiest with emergency repairs. This ensures better availability, often shorter wait times, and allows you to proactively ensure your system is ready for the warmest summer days or the occasional chilly, damp winter nights.
Yes. California has strict appliance efficiency standards (Title 24), so any new equipment must meet the minimum SEER ratings (currently 15+ for AC). More importantly, homeowners should check for available rebates. Central Coast residents can access incentives from programs like TECH Clean California and through local utilities such as Pacific Gas and Electric (PG&E) for upgrading to high-efficiency heat pumps or other qualifying systems, which can significantly offset upfront costs.
Always verify that the contractor holds a valid, current California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license with the CSLB. Choose a locally established company familiar with our specific climate challenges, such as coastal salt air corrosion and the need for systems that handle both cooling and efficient heating for winter. Read verified reviews, ask for references from local jobs, and ensure they perform a detailed load calculation (Manual J) rather than just matching your old system's size.
It can be, depending on the system and conditions. San Luis Obispo's winter nights can dip into the 30s, and standard air-source heat pumps lose efficiency as outdoor temperatures drop. If your system is older or undersized, it may struggle to maintain temperature, leading to longer run times. A reputable local technician can assess if this is normal operation, if your system needs servicing, or if a supplemental heating source (like a hyper-heat model or auxiliary strips) is recommended for our climate.
