AC Installation
San Antonio, TX
New construction, room additions, or first-time central air. We size it right and install it right — the first time.
New AC Installation — Done Right From Day One
Whether you're building a new home in the Hill Country, adding a room, converting a garage, or moving from window units to central air — Good Times HVAC installs the right system from the ground up. We are a Carrier Authorized Dealer with TACLA154716E licensing, and every installation is code-compliant and permit-ready.
The most common installation mistake is oversizing. Contractors guess. We calculate. A Manual J load analysis determines exact tonnage for your space — accounting for insulation, windows, orientation, and San Antonio's extreme heat — before we spec a single piece of equipment. An oversized system short-cycles, wears out prematurely, and never properly dehumidifies your home. In South Texas humidity, that matters.
Jimmy Crenshaw and Austin Privett have installed hundreds of systems across San Antonio, from new construction homes in Schertz to garage conversions in Alamo Heights to Hill Country properties in Boerne. We know the Bexar County permit process, the climate load, and what works in Texas heat.

Carrier System Options for San Antonio
As a Carrier Authorized Dealer, we install the full Carrier lineup — matched to your home's needs and budget:
- 16 SEER2 — Entry-level efficiency, good ROI for moderate usage homes
- 18 SEER2 — Mid-tier efficiency, recommended for San Antonio's 9-month cooling season. Payback vs. 16 SEER typically under 5 years in this climate.

Why San Antonio Homes Need Right-Sized AC Systems
San Antonio averages 100°F+ days from June through August, with a cooling season that runs from April through October — sometimes longer. Most homes use AC 9 out of 12 months. In this climate, system sizing isn't a preference, it's a structural requirement.
An oversized system in San Antonio will cool the space quickly, then short-cycle off before removing humidity. Your home feels clammy and uncomfortable even at 72°F. Mold risk increases. The system wears out 30–40% faster. An undersized system runs constantly and still can't keep up on the worst days.
Manual J eliminates the guessing. We run the calculation on every job — no exceptions.
Our Installation Process
Site Assessment
We evaluate your space, existing electrical capacity, and any ductwork already in place. Nothing is assumed.
Manual J Sizing
Precise load calculation — not rule-of-thumb guessing — determines the correct tonnage for your specific home and orientation.
Written Proposal
Equipment model, efficiency rating, scope of work, and price — all in writing before you commit to anything.
Permit & Install
We pull required permits, install all equipment and line sets, and run ductwork if needed. Typically one day for most jobs.
Commission & Inspect
System is commissioned, refrigerant charge verified, inspected, and registered for full manufacturer warranty.
Frequently Asked Questions
How is installation different from replacement?
Replacement swaps an existing system. Installation is for spaces that have never had AC — requiring new refrigerant lines, electrical, and ductwork from scratch.
Do you install ductless mini-splits?
Yes. Carrier ductless systems are ideal for additions, converted spaces, and rooms where extending existing ductwork isn't practical. We size and install them correctly for your space.
What permits are required?
Most new installations require a mechanical permit from the City of San Antonio. Good Times HVAC handles all permitting as part of the job — you don't coordinate that separately.
How long does a new installation take?
A straightforward residential install typically takes one full day. Jobs requiring new ductwork or electrical panel upgrades may run two days. We give you a specific timeline before we start.
Do you offer financing for new AC installation?
Yes. We offer financing options so you can get a properly sized, high-efficiency system installed today and pay over time. Ask about current promotions when you call.
