Get answers to common questions about hvac services in San Geronimo, California.
San Geronimo's mild, coastal-influenced climate means extreme temperatures are rare, but nights can be cool and summer days can get warm. This makes high-efficiency heat pumps an excellent, all-in-one solution for both heating and cooling, as they operate efficiently in our moderate temperature range. You'll likely use heating more than aggressive air conditioning, so prioritizing a system with a strong heating performance rating (HSPF) is often more cost-effective than one with a maximum cooling (SEER) rating.
For a standard forced-air system replacement (including furnace and air conditioner or heat pump), homeowners in Marin County can expect a range of $9,000 to $15,000+, with complexity and high-efficiency models increasing the price. The hilly terrain and older homes in San Geronimo can add to labor costs if ductwork modifications or difficult access is involved. Always get 3 detailed, itemized quotes from local providers to understand the specific costs for your home.
The ideal times are during the "shoulder seasons"—spring (March-May) and fall (September-November). Scheduling service before the mild summer and cooler winter peaks ensures your system is ready when you need it and provides much greater availability and potential for scheduling flexibility with local HVAC companies. Avoid calling during the first major heat wave or cold snap, as wait times will be longest.
Yes. California has strict appliance efficiency standards; for example, new residential furnaces must be at least 90% AFUE. Furthermore, the Bay Area Air Quality Management District (BAAQMD) has regulations on removing old equipment and may require permits for replacements. A reputable local HVAC contractor will handle all necessary permits and ensure your new system complies with all state and regional environmental and efficiency codes.
Prioritize contractors who are locally based and familiar with the specific challenges of our area, such as older homes, well water systems, and wildfire smoke considerations for air filtration. Verify they hold an active California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license and are insured. Check for strong community reviews and ask for references from recent jobs in West Marin to gauge their reliability and quality of work.
