Most Oxnard AC replacements land between $3,800 and $8,500, with $5,850 the typical price for a 3-ton system on existing ducts. Doing the furnace at the same time brings it to $6,250–$15,350, and a heat pump instead of an AC is $5,300–$12,000.
Oxnard's ocean climate keeps cooling loads light near the coast, so smaller systems and mini-splits are common. California's Title 24 permit and duct-testing rules apply.

Prices cover the Oxnard metro: the city and its close suburbs. Outlying towns can run a little lower; Downtown Oxnard runs a little higher.
HVAC prices across Oxnard
Same city, four kinds of job. Older buildings in Downtown Oxnard take longer, bigger homes in Camarillo, Thousand Oaks & Simi Valley need bigger systems, and Port Hueneme & South Oxnard usually comes in at or under the city typical.
Downtown Oxnard
- Installed
- $4,000–$9,350 installed
- Typical job
- $5,550–$7,400 / 3-ton AC swap
Older homes and mid-rise buildings. A like-for-like condenser swap is routine, but rooftop units and long line runs push quotes toward the top of the range.
Ventura
- Installed
- $3,900–$8,950 installed
- Typical job
- $5,350–$7,050 / 3-ton AC swap
Older houses next to new infill. The swap itself is standard; the extras are undersized ducts, old wiring and line sets that need replacing for the new refrigerant.
Port Hueneme & South Oxnard
- Installed
- $3,800–$8,500 installed
- Typical job
- $5,250–$6,750 / 3-ton AC swap
Established neighborhoods of single-family homes. Most jobs are a standard swap at the city's typical price.
Camarillo, Thousand Oaks & Simi Valley
- Installed
- $3,800–$9,000 installed
- Typical job
- $5,250–$7,150 / 3-ton AC swap
Newer two-story homes are common here, which often means two systems or zoning. Access is easy, so labor per ton is lower.
Real-world HVAC costs in Oxnard
Here's what common HVAC jobs cost in Oxnard in 2026, a 3-ton central AC replacement on existing ducts, installed.
Swap a 3-ton AC on good ducts
Same spot, same size, matched indoor coil, old unit hauled away. Most Oxnard jobs land near $5,850; a 17+ SEER2 unit adds about $2,000.
Replace the AC and gas furnace together
The usual move when both are 15+ years old. One install, one warranty, a matched system. Typical is $9,400.
Switch from AC + furnace to a heat pump
A 3-ton heat pump on existing ducts, typically $7,700. Keeping the furnace as backup (dual-fuel) runs $6,800–$16,350.
Cool one room with a mini-split
A 12,000 BTU single-zone mini-split for a bedroom, office or addition, typically $3,750. A 9,000 BTU unit for a small room is $2,100–$4,600.
Cool a whole home with no ducts
A 4-zone ductless system, typically $11,550. Adding ducts for central AC instead costs $2,400–$9,050 before the equipment.
How much does HVAC cost in Oxnard?
Between $3,800 and $8,500 for a 3-ton central AC on existing ducts, and most Oxnard homeowners pay close to $5,850. Size, efficiency and access set the number: a basic 14.3 SEER2 swap in an easy spot sits at the bottom, and a 20+ SEER2 variable-speed system with an attic air handler sits at the top.
Heating changes the math. A gas furnace alone runs $2,700–$7,700, a 3-ton heat pump $5,300–$12,000, and replacing the AC and furnace together $6,250–$15,350. For Oxnard's climate, a heat pump is the usual fit.
Central AC, heat pump and furnace prices in Oxnard (2026)
A 3-ton central AC runs $3,800–$8,500, a 3-ton heat pump $5,300–$12,000, and a gas furnace $2,700–$7,700, all installed.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| Central AC replacement, 3-ton (existing ducts) | $3,800 | $5,850 | $8,500 |
| Heat pump, 3-ton (existing ducts) | $5,300 | $7,700 | $12,000 |
| Gas furnace (80–96% AFUE) | $2,700 | $4,400 | $7,700 |

| Ductwork replacement, whole house | $2,400 | $5,250 | $9,050 |
The gap between an AC and a heat pump in Oxnard is about $1,850 at the typical price. That gap buys heating as well as cooling, so it matters most when the furnace is near the end of its life.
What moves an HVAC quote in Oxnard:
- Size: a 2-ton system runs about $4,900 and a 5-ton about $8,200 at the typical price. Ask for a Manual J load calculation.
- Efficiency: the minimum here is 14.3 SEER2; a 17+ SEER2 two-stage unit adds about $2,000.
- Access: attic air handlers, rooftop condensers and tight closets add labor, most often in Downtown Oxnard.
- Line set and coil: a new line set runs $190–$620, and the indoor coil has to match the new refrigerant.
- Season: spring and fall bring the best prices; a breakdown during a summer heat wave brings the worst.
Ask every Oxnard contractor for the same things: tonnage, SEER2 rating, model numbers for both the outdoor and indoor units, and whether the permit and line set are included. Compare those, not just the total. Get a quote for your heating and cooling work →
HVAC cost in Oxnard by home size
About $5,300 for a 2.5-ton AC (1,000–1,600 sq ft), $5,850 for 3 tons (1,600–2,000 sq ft), and $7,200–$8,200 for 4–5 tons in homes over 2,500 sq ft, typical Oxnard prices on existing ducts.
Worked example: a 2,000 sq ft Oxnard home with a 16-year-old AC and furnace. Replacing both runs about $9,400; switching to a 3-ton heat pump on the same ducts runs about $7,700; replacing only the AC is $5,850 but leaves an old furnace in place.
Homes over 2,500 sq ft or with two floors often have two systems or zoning. A high-efficiency zoned heat pump runs $9,600–$20,150, and adding zoning to an existing system $1,650–$4,300.
Oxnard HVAC costs by system type
| System type | Cost | Best for |
|---|---|---|
| Central AC, 3-ton (existing ducts) | $3,800–$8,500 installed | Homes with sound ducts and a furnace or air handler to pair with |
| Ductless mini-split, single zone (9,000–18,000 BTU) | $2,100–$6,900 installed | One room, an addition, or a home with no ducts |
| Multi-zone ductless mini-split (2–4 zones) | $4,300–$17,300 installed | Whole homes with no ducts, room-by-room control |
| Heat pump, 3-ton ducted (heats and cools) | $5,300–$12,000 installed | Mild and hot climates; replacing an AC and electric heat |
| Gas furnace + AC, replaced together | $6,250–$15,350 installed | Cold climates with natural gas and old equipment on both sides |
| Gas furnace only (80–96% AFUE) | $2,700–$7,700 installed | When the AC is newer than the furnace |
| Dual-fuel: heat pump + gas furnace | $6,800–$16,350 installed | Cold climates: electric heat most days, gas on the coldest |
| Cold-climate heat pump, 3-ton ducted | $9,100–$23,050 installed | Northern homes leaving gas, oil or propane |
| Central heat pump, high-efficiency with zoning | $9,600–$20,150 installed | Big or two-story homes with hot and cold rooms |
| Evaporative (swamp) cooler, roof-mounted | $1,250–$3,450 installed | Dry Western climates only |
| Geothermal heat pump (ground loop) | $14,400–$33,600 installed | Large lots and long stays in one home |
| Window or through-the-wall AC | $200–$1,150 installed | Single rooms and renters; cheapest way to cool |
Equipment vs installation: the Oxnard AC bill
On a typical $5,850 3-ton swap in Oxnard, the condenser and matched coil are roughly $2,350–$3,500 and the rest is labor, materials, the permit and overhead. Labor usually makes up 40–60% of an AC replacement.
Buying the unit yourself rarely saves much: many contractors won't install customer-supplied equipment, and the ones who do charge $470–$1,900 or more for a mini-split and won't cover the parts. Brand warranties often require a licensed installer.
What's included in an Oxnard AC replacement (and what costs extra)
A standard replacement quote covers the outdoor unit, a matched indoor coil, refrigerant, connection to your existing ducts and wiring, removal of the old unit, and startup. Common extras:
- Permit and inspection: $95–$240, often built into the quote
- New refrigerant line set: $190–$620 if the old one can't be reused
- New condenser pad: $40–$240
- Electrical panel upgrade: $810–$3,800, mostly when adding a heat pump or more capacity
Ask for the AHRI certificate showing the matched rating of your outdoor and indoor units. It proves the system you paid for is the one that was installed.
Climate and what it means here
Oxnard's ocean climate keeps cooling loads light near the coast, so smaller systems and mini-splits are common. California's Title 24 permit and duct-testing rules apply.
System size
Each ton adds equipment cost: about $4,900 for 2 tons and $7,200 for 4 tons at the typical Oxnard price. A Manual J load calculation often shows a smaller system will do.
Efficiency rating
The federal minimum for a new split AC here is 14.3 SEER2 for units under about 3.75 tons, and 13.8 SEER2 for bigger units. Higher ratings cost more upfront and pay back fastest where AC runs most of the year.
New refrigerants
New systems use A2L refrigerants (R-454B or R-32), so the indoor coil must match the outdoor unit. That's why condenser-only swaps are rare now, and why older R-410A systems cost more to service.
Ducts and access
Leaky or undersized ducts, attic air handlers and rooftop condensers add hours. Whole-house duct replacement runs $2,400–$9,050.
Location: Downtown Oxnard vs Port Hueneme & South Oxnard
Downtown Oxnard jobs cost more because of access, parking and older buildings. Port Hueneme & South Oxnard quotes usually sit at or a little under the city typical.
Season and urgency
Replacing on your schedule in spring or fall is cheaper than an emergency swap in a heat wave. After-hours repair labor runs $150–$240 an hour.
- Get three quotes for the same system.Same tonnage, same SEER2 rating, model numbers on every quote. Oxnard quotes for the same 3-ton swap run anywhere from $3,800 to $8,500.
- Replace before it fails.If your system is 12–15+ years old, replace it in spring or fall. Emergency replacements in peak season leave no room to shop around.
- Right-size the system.Ask for a Manual J load calculation. An oversized AC costs more, cycles on and off, and leaves the house clammy.
- Check your utility for rebates.There is no federal tax credit for systems installed in 2026, but many utilities still pay rebates on efficient heat pumps and AC. Check before you sign; most require pre-approval or a listed contractor.
- Do the AC and furnace together if both are old.One install of both runs $6,250–$15,350, less than two separate jobs.
- Keep up with tune-ups.A yearly tune-up at $70–$190 catches weak capacitors and low refrigerant before they kill a compressor ($1,250–$2,900).
Before you pay a deposit to an Oxnard HVAC contractor, get these in writing:
- Tonnage and how it was sized (a Manual J load calculation)
- Model numbers for the outdoor unit and the indoor coil or air handler
- The matched SEER2 (and HSPF2 for a heat pump) rating
- Whether the line set is new, flushed or reused
- Permit, inspection and removal of the old unit
- Thermostat, pad, disconnect and any electrical work
- Parts and labor warranty terms, and who registers the equipment
- Total price, deposit, and start and finish dates
