Homes and HVAC in Fullerton: the local numbers

Housing in Fullerton

  • Fullerton has about 50,344 homes (housing units).
  • The typical (median) home was built in 1969, 7 years older than the California median of 1976.
  • 71% of homes were built before 1980 and 31% before 1960; 4% were built in 2010 or later.
  • The median value of an owner-occupied home is $902,600.
  • 52% of occupied homes are owner-occupied and 48% are rented.
  • 52% of homes are single-family detached houses.
  • The most common heating fuel is natural gas from a utility (67% of homes), followed by electricity (27%).
  • The median home has 4.9 rooms.
  • Median gross rent is $2,194 a month.

When replacing a furnace or air conditioner in a home built around 1969, ask for a load calculation (ACCA Manual J) instead of matching the old unit's size: insulation, windows and duct condition change over the decades, and a correctly sized system runs more efficiently.

Most homes in Fullerton (67%) heat with natural gas, so gas furnaces are the most common heating systems; a yearly furnace inspection and a working carbon-monoxide alarm are worth insisting on.

Licensing and consumer protection in California

Check that any HVAC you hire is licensed and insured before you sign a contract or pay a deposit.

Who regulates this trade

California Contractors State License Board (CSLB)

Licensing boards in other states

Insurance and workers' compensation

$1 million general liability minimum. Workers' compensation is mandatory for any contractor with employees. Bond of $25,000 required for licensure (increased under SB 607).

Mechanic's lien protection

California has one of the strictest lien regimes in the country. Preliminary 20-day notices must be sent within 20 days of starting work. Mechanics liens must be filed within 90 days after project completion (or 60 days after a notice of completion is recorded). Unpaid subcontractors and suppliers can place liens on your property even if you've paid your general contractor in full. Always collect lien waivers from all parties before making final payment.

What catches homeowners out in California

California's CSLB license verification is critical — always check a contractor's license number at cslb.ca.gov and confirm it is active and in good standing. California law requires a $25,000 contractor surety bond on every licensed contractor as a consumer protection backstop. For projects over $1,000 (labor and materials combined under Business & Professions Code § 7048), a valid CSLB license is legally required. Unlicensed contractors face criminal misdemeanor charges, and homeowners who hire them forfeit key statutory protections.
