Get answers to common questions about hvac services in San Lorenzo, California.
For a standard single-family home, a full AC replacement in San Lorenzo typically ranges from $5,000 to $12,000. This range accounts for the moderate Bay Area climate, which often allows for high-efficiency but not oversized units, and includes factors like the complexity of the installation, new refrigerant lines (R-410A is now standard), and potential upgrades to meet California's strict Title 24 energy efficiency standards. Getting multiple detailed quotes is crucial, as labor costs and home-specific challenges can vary.
The optimal times are during the mild shoulder seasons of spring (March-May) and fall (September-November). Scheduling service before the peak summer heat ensures your system is ready for San Lorenzo's occasional 90°F+ days and helps you avoid the high demand and potential emergency rates of July and August. For furnace checks, early fall is ideal to prepare for our cool, damp winters, allowing technicians more availability and you more scheduling flexibility.
Yes. All HVAC contractors must be licensed by the California Contractors State License Board (CSLB). Furthermore, installations must comply with California's 2022 Title 24, Part 6 energy code, which often requires specific system efficiencies and may involve a HERS (Home Energy Rating System) test. Homeowners should also check for rebates from BayREN and through programs from local utilities like PG&E, which offer incentives for upgrading to high-efficiency heat pumps and air conditioners.
Always verify the contractor holds a valid CSLB license (C-20 specialty classification for HVAC) and carries both liability and worker's compensation insurance. Look for established local companies with strong reviews on platforms like Nextdoor, as they understand the specific housing styles (e.g., mid-century homes) and microclimates of the San Lorenzo area. A reputable provider will perform a detailed load calculation (Manual J) for replacements, not just swap units based on tonnage.
Yes, this is a common concern. Standard air-source heat pumps can lose efficiency as outdoor temperatures drop into the 40s and below, which happens on San Lorenzo winter nights. During these colder periods, the system's auxiliary electric resistance heat (the "emergency heat" strip) may engage, which uses significantly more energy. For optimal year-round comfort and efficiency, discuss options like a dual-fuel system (heat pump with a gas furnace) or a cold-climate specific heat pump model with your local technician.
