How Much Does a New HVAC System Cost in San Diego?

If you’re considering upgrading or replacing your heating and cooling system, you’re probably asking: How much does a new HVAC system cost in San Diego? The answer depends on several factors, including your home size, energy efficiency preferences, and system type. In this guide, Heat Busters Inc breaks down everything you need to know about HVAC installation in San Diego, from typical price ranges to what affects the total cost.

Average New HVAC System Cost in San Diego

In general, the new HVAC system cost in San Diego ranges from $7,000 to $15,000, depending on the complexity of the job. For a standard 3-ton system in a 1,500 sq ft home, the cost to install an HVAC system in San Diego typically falls between $8,000 and $12,000, including equipment, labor, and permits. Here’s a quick price breakdown:

Basic HVAC replacement: $6,500 – $8,500
Mid-tier system with better energy efficiency: $9,000 – $12,000
High-efficiency or multi-zone systems: $12,000 – $18,000+

If ductwork needs to be repaired or replaced, that can add $2,000–$5,000 to the total project cost.

Factors Affecting HVAC Installation Costs

When it comes to HVAC in San Diego, CA, no two homes are alike. Several elements affect the overall cost:

System Size and Capacity: Larger homes require systems with greater tonnage. A unit that’s too small won’t cool or heat effectively, while one that’s too large will waste energy. Residential HVAC systems in San Diego are usually sized between 2–5 tons.
Energy Efficiency (SEER Rating): A higher SEER rating means better efficiency—but also a higher upfront cost. A 14 SEER system (minimum by law in California) will cost less than a 20+ SEER system but may have higher long-term utility bills.
Type of System: Your cost will also depend on whether you need:

Existing Infrastructure: If you already have ductwork and it’s in good shape, costs will be lower. However, if ductwork is old, leaky, or missing, it must be repaired or added, which increases labor and material expenses.
Permits and Compliance: San Diego County requires HVAC permits and energy code compliance (Title 24), which means additional inspections and fees. Always hire a licensed HVAC contractor in San Diego California who handles this process for you—like Heat Busters Inc.
