Frequently Asked Questions About HVAC in San Mateo

Get answers to common questions about hvac services in San Mateo, California.

1What is the typical cost range for replacing a central air conditioner in a San Mateo home?

For a standard single-family home, a full AC replacement in San Mateo typically ranges from $8,000 to $15,000. This wide range depends on the system's size (tonnage), efficiency rating (SEER), and the complexity of the installation, such as ductwork modifications. San Mateo's moderate coastal climate means you may not need the highest capacity unit, but investing in a higher SEER (16+) system can offer better humidity control and long-term savings, especially with PG&E's high electricity rates.

2When is the best time to schedule HVAC maintenance or replacement in San Mateo?

The ideal time is during the "shoulder seasons"—late spring (April-May) or early fall (September-October). This avoids the peak summer demand when HVAC companies are busiest with emergency repairs, ensuring better scheduling and potentially lower off-season promotional pricing. Proactive maintenance before summer is crucial as our cool, foggy mornings can give way to surprisingly hot afternoons, putting sudden strain on an unprepared system.

3Are there any local regulations or rebates I should know about for HVAC work in San Mateo?

Yes, California has strict regulations. All new installations must comply with the 2022 Title 24 energy codes, which require specific efficiency standards and may mandate smart thermostats. Furthermore, San Mateo County falls under the Bay Area Air Quality Management District (BAAQMD), which has rules on refrigerant handling and system disposal. Significant rebates are available through BayREN and TECH Clean California for upgrading to high-efficiency heat pumps or other qualifying systems.

4How do I choose a reliable HVAC contractor in San Mateo?

Always verify the contractor holds a valid California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license and carries ample insurance. Look for companies with strong local experience, as they understand the specific challenges of Peninsula homes, like managing indoor humidity during our damp winters. Check reviews on platforms like Nextdoor for hyper-local feedback and ask for references from recent installations in your specific San Mateo neighborhood.

5My home feels drafty and unevenly heated. Is this common in San Mateo, and what's the solution?

This is very common due to our older housing stock and the "microclimate" effect, where wind and fog exposure vary. The primary solution is not just a new furnace, but a comprehensive home performance assessment. A quality local HVAC provider will evaluate and seal your ductwork (which often runs in uninsulated crawl spaces), improve attic insulation, and may recommend a properly sized heat pump system that provides both efficient heating and dehumidification for our mild but damp winters.
