HVAC Installation Near Me — What It Costs and How It's Done Right
Manual J sizing, permits, and flat-rate installed pricing
HVAC installation near me in the Antelope Valley costs $14,490 to $24,990 installed for a complete 3- to 5-ton air conditioner and furnace system, including equipment, labor, permits, thermostat, new line set or flush, disposal of the old unit, and startup commissioning. Price is driven by tonnage, efficiency tier, and whether ductwork needs replacement. DC Air and Heating performs a Manual J load calculation on every quote rather than matching the old unit's size, pulls the LA County or Kern County permit, and registers the manufacturer's parts warranty in your name. Installs are typically completed in one day, and financing starts at 0% APR for 24 months.

Frequently Asked Questions
How much does HVAC installation cost near me?
In Southern California a complete AC and furnace installation runs $14,490 to $24,990 for a 5-ton system, with each tonnage step down reducing the price by roughly $500. That includes equipment, labor, permit, thermostat, and haul-away.
How long does HVAC installation take?
Most single-system change-outs are completed in one day, roughly 6 to 9 hours. Adding ductwork, converting to a heat pump, or relocating equipment extends the job to two or three days.
Do I need a permit for HVAC installation?
Yes. Los Angeles County and Kern County both require a mechanical permit for equipment change-outs. We pull it and schedule the inspection — an unpermitted install can complicate a future home sale.
What size HVAC system do I need?
It depends on square footage, insulation, window area, ceiling height and orientation — not on the old unit's size. Use our HVAC sizing calculator for a ballpark, then we confirm with a Manual J load calculation on site.
Is it better to replace the AC and furnace together?
Usually yes. Mismatched components lose rated efficiency, and replacing both at once avoids paying twice for labor, refrigerant line work and permits. If the furnace is under seven years old, a coil-and-condenser-only replacement can make sense.
What financing is available for a new HVAC system?
Synchrony plans: 0% APR for 24 months, 5.99% for 58 months, or 7.99% for 115 months on approved credit. A $16,990 system is about $708/month at 0% for 24 months or roughly $328/month over 58 months.
