Factors That Affect HVAC Cost

Home Size & System Capacity

Larger homes require more powerful (and expensive) systems. A 1,500 sq ft home needs about 2 tons, while 3,000+ sq ft may need 5 tons.

Efficiency Rating (SEER/AFUE)

Higher efficiency units cost more upfront but save on energy bills. Look for ENERGY STAR certified systems for potential tax credits.

If existing ductwork needs repair or replacement, expect to add $1,000-$5,000 or more to the project cost.

Regional Labor Rates

HVAC labor rates vary from $75-$150/hour nationally, with major metro areas like the Bay Area running 15-30% higher.
