$5,500 to $18,000 installed, averaging about $9,200 for a complete system in a typical single-family home.

How long does an HVAC system last?

Central AC and heat pumps last 12–17 years, gas furnaces 15–25 years. Replace rather than repair once you cross about 75% of that life.

What size system do I need?

A heat pump costs more upfront but usually cuts total energy bills where electricity is reasonably priced, and it qualifies for a larger tax credit.

How long does installation take?

One day for a straight equipment swap; two to four days if the ductwork or electrical service is being replaced.

What drives La Mesa pricing

Local labor

Licensed La Mesa contractors carry California workers' comp and prevailing wage pressure, and crews here quote roughly 16% above the national labor average. Demand in the San Diego market peaks in spring, so booking early usually beats a rush premium.

Permits & code

La Mesa follows the California Building Standards Code, so most structural, electrical, plumbing and re-roof work needs a permit from the La Mesa building department plus Title 24 energy compliance. Coastal overlay zones and brush-management setbacks add review time in much of San Diego County.

Climate & conditions

La Mesa sits in a mild coastal climate with salt-air corrosion near the water, so expect corrosion-resistant fasteners and UV-stable finishes.
