AC Replacement in Kingsland, Austin & the Texas Hill Country
When your air conditioner is past saving, O2 Kool replaces the full system — properly sized, correctly installed, and commissioned before we leave. Honest repair-vs-replace assessment, high-efficiency equipment, financing available, and full removal of the old unit.
When is AC replacement the right call in Kingsland, Texas?
AC replacement makes sense when the system is 12+ years old, uses R-22 refrigerant, has a failed compressor, needs repairs that exceed half the cost of a new system, or keeps driving up energy bills season after season. O2 Kool provides an honest in-home repair-vs-replace assessment, handles Manual J sizing on the new equipment, removes and disposes of the old system, and offers financing through Wells Fargo and Synchrony Bank.
Signs It's Time to Replace, Not Repair
Central Texas AC systems work harder than most. Between the long cooling season, the heat, and occasional hail, systems here rarely make it past 15 years. When several of these signs stack up, replacement almost always wins on cost, comfort, and peace of mind.
- System is 12+ years old
- Uses R-22 refrigerant (phased out by the EPA)
- Compressor has failed or is failing
- Repair cost exceeds 50% of a new system
- Two or more repairs in the past twelve months
- Energy bills keep rising season over season
- Home has uneven temperatures despite multiple repairs
- System is undersized or oversized for the home
- Excessive humidity inside the home in summer
- AC is loud, inefficient, and never quite cools
Honest Repair-vs-Replace
We have no incentive to oversell a replacement. If your system has years of service left, we tell you. If it doesn't, we tell you that too — with the math behind the recommendation.

From the first in-home visit to final walkthrough, here's exactly how a replacement job runs.
- 1
Honest Repair-vs-Replace Assessment
Before we quote a replacement, we evaluate whether repair still makes sense. If a capacitor, contactor, or refrigerant recharge will get you several more seasons out of a newer system, that is what we recommend. Replacement only makes sense when the math clearly favors it.
- 2
Manual J Sizing on the New System
We don't replace an oversized unit with another oversized unit. A proper Manual J load calculation determines the correct tonnage for your home's current insulation, windows, and layout — which may differ from the unit you're removing.

Equipment Selection & Efficiency Options
You see real options — standard efficiency, high efficiency, variable-speed, heat pump, or ductless mini-split — with the tradeoffs explained in plain language. We match the system to your home, not to a sales quota.

Written Quote With Financing Options
Itemized quote covering equipment, labor, permits, thermostat, line sets, and old-system disposal. Financing available through Wells Fargo and Synchrony Bank for approved applicants.

Old System Removal & Responsible Disposal
We remove the old indoor and outdoor units, recover the existing refrigerant per EPA requirements, and haul everything away. You never have to see a rusty condenser sitting on your patio after we leave.

New System Installation & Commissioning
Indoor and outdoor units installed to manufacturer spec. Line sets evacuated to 500 microns. Refrigerant charge verified by superheat/subcooling. Ductwork inspected and sealed. Full airflow and static-pressure commissioning before we leave.
What You Gain From a New High-Efficiency System
Lower Energy Bills Every Month
A modern SEER2 15 system uses roughly 30–40% less electricity than a 10-year-old SEER 10 unit running the same hours — meaningful savings over a full Texas cooling season.
Manufacturer Warranty Reset
New systems typically carry a 10-year parts warranty (with registration) and a labor warranty from O2 Kool. If something fails in the covered period, you are covered.
Modern Refrigerants
R-22 is phased out. Newer refrigerants (R-410A, R-32, R-454B) are cheaper to service, better for the environment, and required on all new residential equipment.
Quieter, More Consistent Cooling
Variable-speed compressors and ECM blowers hold temperature within a half-degree of setpoint, run quieter than old single-stage units, and remove more humidity.
What's Included With Every AC Replacement
Financing Makes Replacement Manageable
A new AC doesn't have to be a cash event. O2 Kool partners with Wells Fargo and Synchrony Bank so approved buyers can spread the cost over monthly payments — often with promotional financing available.

AC Replacement — Frequently Asked Questions
When should I replace my AC instead of repairing it?
General rule: if the repair cost exceeds 50% of a replacement, the system is 12+ years old, uses R-22 refrigerant, or has needed multiple repairs in the past year, replacement is usually the smarter long-term call. We give you the math honestly — we win either way, so the recommendation is based on your situation, not our margin.
How long does AC replacement take?
A straightforward same-tonnage, same-refrigerant replacement typically takes one day. Replacements that also involve ductwork repairs, electrical upgrades, or switching from a furnace to a heat pump can take two to three days. You'll have a realistic timeline in your written quote before any work begins.
What SEER rating should I buy for a Texas home?
The federal minimum for the southern U.S. is currently SEER2 14.3. For Central Texas — where AC runs eight to ten months a year — stepping up to SEER2 15–17 typically pays back the price difference in energy savings within the first few cooling seasons. Premium variable-speed systems (SEER2 18+) make sense for larger homes, humidity-sensitive spaces, or buyers planning to stay 10+ years.
Do you take the old AC unit away?
Yes. O2 Kool handles full removal and responsible disposal of your old system, including EPA-compliant refrigerant recovery. You never have to coordinate scrap pickup or store a dead compressor in the garage.
Will a new AC lower my electric bill?
Almost certainly. A properly sized, correctly installed high-efficiency system uses significantly less electricity than a 10+ year-old unit running the same hours. How much depends on your current equipment, usage, and rate — ask your technician for a realistic range based on the system you select.
Do you offer financing for AC replacement?
Yes. O2 Kool offers financing through Wells Fargo and Synchrony Bank, which can make replacement surprisingly affordable on a monthly basis. Ask your technician during the estimate, call (325) 388-5665, or visit our financing page for current offers.
