Material Prices
While this table focuses on replacement *system* types, it provides a general price indication. The type of “material” in HVAC refers to the system components and their construction, which affect efficiency and cost.
| System Type (Analogous Material) | Description | Approximate Cost (Installed) |
|---|---|---|
| Standard Efficiency Split System (Vinyl) | Base model AC and furnace. Lower upfront cost but higher running costs. Increasingly less common due to efficiency standards. | $8,000 – $11,000 |
| High-Efficiency Split System (Wood) | Higher SEER2 rated AC and furnace. Better energy savings, qualifies for some rebates. | $11,000 – $14,000 |
| Heat Pump System (Fiberglass – advanced composite) | Electric system for both heating and cooling. The preferred system for California due to energy efficiency and rebates. Can utilize existing ductwork. | $12,000 – $16,000+ |
Local Factors
In Kentfield, which is part of Marin County, you’ll need to obtain the necessary permits for HVAC and AC replacement. These permits ensure the installation meets local building codes and safety standards. Your HVAC contractor should be knowledgeable about the permitting process and handle it on your behalf.
Installation labor rates in Marin County are generally higher than the state average due to the higher cost of living and demand for skilled tradespeople. Expect to pay a premium for experienced, licensed contractors. Remember to verify contractor license at California Contractors State License Board (CSLB). Unlicensed work carries significant risks and fines.
Furthermore, California’s Title 24 energy efficiency standards are strictly enforced. This means your new system must meet specific requirements for duct sealing and overall energy performance. Failing to comply can result in fines and the need for costly rework.
Weather Impact
Kentfield experiences a Mediterranean climate with mild, wet winters and warm, dry summers. While not as extreme as the Central Valley, summers can still be hot enough to warrant efficient air conditioning. The increasing frequency of wildfires in California has also made indoor air quality (IAQ) a major concern. When choosing your new system, consider features like high-efficiency MERV 13 filters or air scrubbers to protect against smoke and pollutants. Investing in a system with these features can greatly improve your indoor air quality and protect your health.
Given California’s “Heat Pump Push,” these systems are highly recommended. They offer both heating and cooling, are extremely energy efficient, and qualify for significant state and federal rebates under the Inflation Reduction Act. 2026 SEER2 units are designed to maximize these savings. Choosing the right SEER2 rating can lead to substantial long-term cost savings on your energy bills.

FAQ
- How long does HVAC replacement take?
A typical HVAC replacement in Kentfield takes between 1-3 days, depending on the complexity of the installation and any necessary ductwork modifications. Heat pump installations might take longer due to electrical work.
- Do I need to replace my ductwork when replacing my AC?
Not always, but it’s highly recommended to inspect your ductwork. Leaky or damaged ducts can significantly reduce the efficiency of your new system. Sealing or replacing ducts is often a worthwhile investment. Title 24 compliance will often mandate duct testing.
- What SEER2 rating should I choose?
The higher the SEER2 rating, the more energy-efficient the system. While higher SEER2 units have a higher upfront cost, they can save you money on your energy bills in the long run. Consult with your HVAC contractor to determine the best SEER2 rating for your home and budget. Consider the rebate programs available for high SEER2 ratings.
