AC Installation & Replacement in New Braunfels, TX
Full AC system replacement, mini-split installation, condenser swaps. Right-sized for the New Braunfels climate. High-SEER options for lower summer power bills.
What AC Installation Covers
An AC replacement in New Braunfels usually takes a long day for a split system: remove the old indoor coil and outdoor condenser, install matched-tonnage replacements, flush or replace the line set as needed, modify the plenum if the new evaporator coil is a different size, wire the new thermostat, and start up with a full refrigerant charge. Most projects also include a condensate-line inspection and air-handler base modifications.
Sizing matters more in Hill Country than most climates. Oversized systems short-cycle (cools the air but doesn't run long enough to remove humidity); undersized systems run constantly and never quite catch up. A proper Manual J load calculation considers home square footage, insulation R-value, window area and orientation, attic insulation, and infiltration rate. Done correctly, the new system runs less often, dehumidifies better, and costs less per month to operate than the unit it replaced.
Pricing depends on tonnage, SEER rating, and any ductwork modifications required. Itemized quotes in writing before work begins. Manufacturer rebates and CPS Energy/Pedernales Electric Cooperative incentives applied where available.
Replace vs Repair Decision
Replace when: the system is 12+ years old, still using R-22 refrigerant, has had two or more major repairs in the last 3 years, or summer electric bills have climbed steadily over the last few years even with similar usage. The economics of replacement on a system at that age typically pencil out within 5-7 years.
Repair when: the system is under 10 years old, the failed part is a single component, and the rest of the unit is sound. A capacitor or contactor replacement extends a healthy system's life by years.

AC Installation & Replacement FAQ
Minimum federal standard is now SEER2 14.3 in the South region. For Hill Country homes running AC 6+ months per year, SEER 16-18 is the value sweet spot — meaningful power savings without the cost premium of top-tier 20+ SEER units. Variable-speed systems (instead of single-stage) offer better dehumidification, especially in homes with high humidity sensitivity.
A like-for-like split-system replacement is typically one day on-site (8-10 hours). Adding ductwork modifications, electrical upgrades, or converting to a heat pump can extend to 2 days. Mini-split installations vary by number of zones — single-zone is half a day, multi-zone is 1-2 days.
Heat pumps work as both AC and supplemental heating, which fits Hill Country winters where heating demand is light. A heat pump can replace both a furnace and AC if combined with a small electric backup heat strip. Higher upfront cost but lower long-term operating cost for many New Braunfels homes.
Most New Braunfels homes built in the last 30 years have ductwork that's sized for the original AC tonnage. If you're upgrading to a larger system or converting to a high-velocity / mini-split, the ducts may need rework. A duct inspection during the replacement estimate identifies any modifications needed.
