Considering HVAC or AC replacement in San Marino? You’re likely looking at a project costing between $8,000 and $16,000 for a full system replacement. This price range varies depending on the system’s size (BTU rating), efficiency (SEER2 rating), the complexity of the installation, and the specific brand you choose. Remember to explore our complete California Heating & Cooling guide for detailed information on state regulations and best practices.
Material Prices
While material costs for the HVAC unit itself don’t drastically change by location, here’s a general price guide. Keep in mind these are *approximate* and exclude installation. Prices are also impacted by SEER2 rating (higher SEER2, higher cost).
| HVAC System Type | Estimated Material Cost (Unit Only) | Notes |
|---|---|---|
| Heat Pump (3-Ton, 16 SEER2) | $4,000 – $7,000 | Highly recommended for California’s push towards electrification. Qualifies for significant rebates. |
| Central AC Unit (3-Ton, 16 SEER2) | $3,000 – $6,000 | May be paired with a gas furnace, but heat pumps are increasingly favored. |
| Furnace (Natural Gas, 80% AFUE) | $1,500 – $3,000 | Less common as standalone install. Often paired with AC unit for existing homes. |
| Ductwork (Replacement/Repair) | $500 – $2,000+ | Critical for Title 24 compliance. Leaky ducts dramatically reduce efficiency. |
Local Factors
San Marino falls under Los Angeles County, which requires permits for HVAC installations and replacements. Expect to pay permit fees, typically a few hundred dollars. These fees ensure the work meets local building codes and Title 24 energy efficiency standards.
Installation labor rates in San Marino are higher than the national average due to the high cost of living and demand for skilled HVAC technicians. Labor can easily account for 50-60% of the total project cost. Always get multiple quotes from licensed contractors. Important: Verify contractor license at California Contractors State License Board (CSLB). Unlicensed work can result in hefty fines.
Weather Impact
San Marino experiences hot, dry summers. This creates a high demand for efficient cooling systems. Investing in a high SEER2 rated AC unit or, preferably, a heat pump, is crucial for managing energy costs. Furthermore, given California’s increasing wildfire risk, consider systems with high-efficiency air filters (MERV 13 or higher) or air scrubbers to protect indoor air quality from smoke particles. These IAQ add-ons can substantially improve your home environment.

FAQ
- How long does HVAC replacement take? Typically, a standard HVAC replacement takes 1-3 days, depending on the complexity of the job, ductwork modifications, and permit inspections.
- What SEER2 rating should I choose? In 2026, aim for at least 16 SEER2. Higher SEER2 ratings (18+) offer greater energy savings but come with a higher upfront cost. Consider your long-term energy consumption and available rebates.
- Do I need to replace my ductwork when I replace my HVAC system? Not always, but it’s highly recommended, especially if your existing ductwork is old, damaged, or leaky. Leaky ductwork significantly reduces efficiency and can negate the benefits of a new, high-efficiency system. Duct sealing or replacement is often required for Title 24 compliance.
