Most replacements run $10,000 to $22,000
A full AC replacement typically falls between $10,000 and $22,000, depending on system size, efficiency rating, and whether your existing ductwork needs attention. We give you a firm written quote after a free load calculation — never a phone estimate based on your old system’s size alone.
How to know it’s time
System is 12+ years old
Most residential AC systems have a realistic service life of 10-15 years in Central California’s climate. Beyond that, repairs become a losing bet.
Repair cost approaches replacement
If a single repair quote is climbing toward 40-50% of a new system’s cost, replacement is usually the better long-term investment.
Uses R-22 refrigerant
Older systems using phased-out R-22 refrigerant face rising repair costs as the refrigerant itself becomes scarce and expensive.
Rising energy bills
An aging, inefficient system can cost hundreds more per year to run than a modern high-efficiency replacement.
Frequent breakdowns
More than one or two repair calls per season is often a sign the system is failing gradually rather than facing one fixable issue.
Uneven cooling
Rooms that never quite cool properly can indicate a system that was undersized or mismatched from the start.
Sized right, quoted in writing, installed fast
Free load calculation
We assess your home’s actual cooling needs on-site, not a phone estimate based on your old system’s size.
Written scope & price
A clear quote covering equipment, any ductwork work needed, and electrical — before any commitment.
Same-day or next-day install
Most standard replacements are completed in a single day once scheduled.
Video-documented completion
You get a completion video of the finished system, plus written warranty terms for your records.

If your system just needs a fix, not a full swap, start with AC repair instead. If you’re adding AC to a home for the first time rather than replacing an existing system, see AC installation. If it’s your furnace instead of your AC, see furnace repair or furnace installation.
$0 down turns a $15,000 replacement into $833/month
At 0% interest over 18 months, a $15,000 system is about $833/month. Longer terms are available for a lower monthly payment. Most homeowners are approved same day with no hard credit pull. See HVAC financing for full terms and other project examples.

AC replacement FAQ
How much does AC replacement cost?
Most replacements range from $10,000 to $22,000, depending on system size, efficiency rating, and ductwork condition. We provide a free itemized quote after a load calculation, never a phone estimate.
How do I know if I need replacement instead of repair?
Systems over 12 years old, repeated breakdowns, or a repair quote approaching 40-50% of replacement cost are all signs replacement is the better investment. See AC repair to compare, or book a free diagnostic so you decide with full information.
How long does replacement take?
Most standard replacements are completed in a single day once scheduled. Larger projects involving ductwork take longer.
What warranty comes with a new system?
Every replacement includes a written warranty. Your estimator will confirm exact terms for your specific system during the quote.

AC Replacement — right system, properly sized, Installed Right or we come back.
Most AC replacements fail early because of two mistakes — wrong system size and poor installation. Grandmark starts with a load calculation, not a brand catalog. Licensed technicians. Video-documented. $0 down financing. Free estimate across all 5 California markets.
A new AC system shouldn’t wait because of budget timingand with $0 down, it doesn’t have to.
Every day a failing AC system runs in California’s heat, it’s getting closer to complete failure — and complete failure in peak heat always costs more than a planned replacement. Financing removes the financial reason to wait.

Which AC system is right for your California home or business?
Central split system
The standard AC and air handler combination — condenser outside, air handler inside, connected by refrigerant lines and ductwork. Properly sized and installed in a home with good duct integrity, the most cost-effective solution for most California homes.
Heat pump system
Provides both heating and cooling using the same equipment. In California’s moderate winters, significantly more energy-efficient for heating than a gas furnace. Sacramento, Fresno, and Modesto climates are well-suited to heat pump performance.
High-efficiency systems — SEER2 18–26
In Central Valley markets where AC runs 12–16 hours per day for 4–5 months, the payback period on a high-efficiency upgrade is typically 4–7 years — after which the efficiency savings are pure value. We calculate the actual payback period for your usage pattern.
Ductless mini-split systems
Targeted cooling and heating for specific rooms without requiring ductwork — ideal for room additions, converted garages, detached structures, and homes where extending ductwork isn’t practical. Each indoor unit independently controlled.
Commercial packaged units and rooftop systems
Commercial buildings most commonly use packaged rooftop units — all components in a single cabinet on the roof, with only ductwork connections running into the building. All major commercial brands installed and serviced. COIs provided. Zero business disruption standard across all 5 California markets.
Should you repair or replace? Here’s how to think about it honestly.
We give you an honest recommendation — we don’t push replacement when repair is the right answer. Here are the signs replacement makes the better financial decision in California’s climate.
System is 12+ years old with 2+ repairs in 3 years
The repair cost is approaching the replacement cost — and the next failure is already building
Compressor has failed or is near failure
Compressor replacement on an older system rarely makes financial sense when full replacement costs the same or less
System uses R-22 refrigerant
R-22 is no longer manufactured. Remaining supplies are expensive and diminishing. Maintaining an R-22 system is a losing financial proposition
Energy bills increasing despite similar usage
Aging inefficient systems consume 20–40% more electricity than a modern replacement — the savings often fund the financing payment
inconsistent temperatures room to room
Often a sign the system was never properly sized or the ducts have never been assessed — both addressed in a Grandmark replacement
Repair cost exceeds 50% of replacement cost
The industry standard decision point — especially relevant in California where aging systems are already running harder than they were designed to

Awesome service. Very friendly!
Melanie Allison
Fresno, CA
I had my HVAC system replaced by Grandmark about 2 1/2 years ago. It recently started having an issue with the main system not shutting down. The technicians came out promptly, diagnosed the issue, and replaced the faulty part. Bill W was very professional and the problem was solved quickly. Great company!
