$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 South Gate pricing

Local labor

Seismic bracing and soft-story retrofit rules apply to many older LA-area properties, and hillside lots trigger extra geotechnical review.

South Gate sits in a warm Mediterranean climate with intense summer sun, so expect UV-stable, heat-tolerant materials and shaded scheduling in peak summer.
