What a New HVAC System Costs in Orange County (2026)

What a proper installation includes
Heat pump or gas furnace plus AC?
Because Orange County winters are mild, a heat pump is the right choice for most homes. One efficient system handles both heating and cooling, you can save roughly $400 to $900 a year versus gas, and heat pumps qualify for the largest rebates and tax credits.
Rebates and financing
The federal 25C tax credit ended December 31, 2025. Rebate funding and amounts change over time – we confirm exactly what is available for your home.
What size system do I need?
We never guess – we run a proper load calculation on your home so you get the right size.
Red flags when comparing quotes
- A full-system quote far under $9,000 (usually cheap offshore equipment or cut corners)
- No permit pulled
- No load calculation
- High-pressure, “today only” pricing
- A “cash discount” to skip the paperwork

Major Component Replacement Costs
These are the expensive parts. When one of these fails on a system that is 10+ years old, it is usually worth comparing the repair against a full replacement (see “Repair or Replace?” below).
| Major Part | Typical OC Cost | Notes |
|---|---|---|
| Compressor (AC / heat pump) | $1,500 – $3,500 | The heart of the system |
| Evaporator coil (indoor) | $1,200 – $3,000 | Common refrigerant-leak point |
| Condenser coil (outdoor) | $1,000 – $2,800 | Outdoor heat-exchange coil |
| Furnace heat exchanger | $1,500 – $3,500 | Cracked = often replace the furnace |
| Refrigerant line set | $600 – $1,800 | Lines between indoor & outdoor units |
| Ductwork repair (per section) | $350 – $1,500 | Sealing or replacing damaged runs |
| Full ductwork replacement | $4,000 – $12,000 | Needed in about 1 in 3 homes |
Tune-Ups, Maintenance & Indoor Air Quality
Regular maintenance is the cheapest HVAC money you will spend – it prevents most breakdowns and keeps efficiency (and your utility bills) in check. Indoor air quality add-ons are optional upgrades that improve comfort and health.
| Service | Typical OC Cost | Notes |
|---|---|---|
| AC or heating tune-up (one system) | $89 – $199 | Recommended once per year |
| Annual maintenance plan (both systems) | $150 – $350 / yr | Includes priority service & discounts |
| Standard air filter | $20 – $80 | Change every 1 – 3 months |
| High-efficiency media filter | $40 – $120 | Whole-home cabinet filters |
| Smart thermostat installed | $250 – $550 | Lowers bills, app control |
| UV germicidal light | $400 – $900 | Reduces mold & bacteria on the coil |
| Whole-home media air cleaner | $600 – $1,200 | Captures fine dust & allergens |
| Whole-home air scrubber / purifier | $1,200 – $3,000 | Active whole-house air treatment |
| Whole-house humidifier | $400 – $1,200 | Adds moisture in dry months |
| Duct cleaning | $400 – $900 | Whole-home duct system |
| Duct sealing (Aeroseal or manual) | $1,200 – $3,500 | Stops leaks, improves airflow |
Repair or Replace? How to Decide
A quick rule of thumb: multiply the repair cost by the age of your system. If the number is over about $5,000, replacement is usually the smarter long-term move. A $400 capacitor on a 6-year-old unit ($2,400) is an easy repair. A $2,500 compressor on a 12-year-old unit ($30,000) almost always points to replacement.
Lean toward repair when the system is under ~10 years old, the fix is minor (capacitor, contactor, ignitor, thermostat), and the unit is otherwise efficient. Lean toward replacement when a major part fails (compressor, heat exchanger, coil) on a 10+ year-old system, when you still run R-22 refrigerant (phased out and very expensive to recharge), or when repairs are becoming a yearly habit and energy bills keep climbing.

What your neighbors say
I cannot thank South County Air Services enough for impeccable customer service. Behshad came out on a Saturday to check my heating unit (failing motor). He was professional, knowledgeable, courteous and thorough – extremely fair pricing, with open and honest communication. Highly recommend. Five star plus!
Super impressed with our experience. We needed to replace our 40+ year old furnace, and from the first call everything was easy and clearly explained. Responsive, great follow-up, great pricing, timely booking, installers on time and prepared, clean install, no mess left.
I am grateful to the technician who inspected my HVAC system today. I feel he did a thorough inspection and told me the truth about my unit. I had two other companies beforehand – the first gave me a report that would call for major expenditure.
You will not find a more honest and knowledgeable HVAC tech. They show up on time and are very professional, but most of all will not try to upcharge you. He could have charged me significantly more but cares about diagnosing the actual problem. I found my HVAC tech – 10 star review if I could!
It’s not often you find an honest business willing to give suggestions over the phone to troubleshoot why my HVAC wasn’t working – without charging me. After a couple minutes we determined my breaker popped and all I needed was to reset it. I appreciate Behshad and will definitely use him in the future.
I spoke with the owner on a Saturday morning and he was at my house within 45 minutes. Another company wanted $3,000 in repairs; Behshad recommended a simple $250 repair that fixed the issue. Very honest, thorough, and reliable!
