How to know it’s replacement, not repair
12+ years old
Most residential AC systems last 12-15 years. Past that, parts get harder to find and efficiency drops well below what a new system delivers.
R-22 refrigerant
R-22 was phased out of production in 2020. If your system uses it, any refrigerant leak repair gets more expensive every year as supply shrinks.
Repair costs adding up
If you’re spending more than 30% of a new system’s cost on repairs — or more than once a season — replacement is usually the better long-term investment.

What Fresno homeowners say
4.8 stars across 1,200+ verified Google reviews — Fresno, Clovis, Madera, Sanger, Selma, and surrounding Fresno County cities.
Had the same AC problem fixed twice by two other Fresno HVAC companies. Grandmark found the real cause on video — a slow refrigerant leak nobody had checked. One repair. No more problems.
They replaced our AC and sealed the ducts at the same time. Didn’t know that was even possible with one company. House is cooler than it’s been in years and I have video proof of every step.
Our old unit was on its last leg — Grandmark showed us the numbers on video and it was clear repair wasn’t worth it anymore. New system installed same week, no pressure the whole time.

AC replacement FAQ
Should I repair or replace my AC?
Generally, repair makes sense if your unit is under 10 years old and the repair cost is less than 30% of replacement. Replacement usually wins if your system is 12+ years old, runs on R-22 refrigerant, or you’re spending more than $1,500 per season on repairs. We show you the real numbers on video, not just a recommendation.
How much does AC replacement cost in Fresno?
Standard 14-16 SEER systems start around $6,500 installed. Premium variable-speed systems (19+ SEER) start around $12,400. Exact pricing depends on system size, ductwork condition, and home square footage — you get a written quote after a free in-home estimate.
How long does AC replacement take?
Most standard replacements are completed in 6-8 hours for a straightforward swap. Jobs requiring ductwork repair or modification typically take 1-2 additional days.
What size AC unit do I need?
It depends on square footage, insulation, window orientation, and ceiling height — calculated through a Manual J load calculation, not just matched to your old unit’s tonnage. An oversized system short-cycles and wears out early; an undersized one runs constantly and never quite keeps up.
Do you offer financing for AC replacement?
Yes — $0 down, 0% interest for 18 months, or 4.99% APR over 144 months for larger systems. Same-day approval in most cases with no hard credit pull.
