Home of the 365-Day, No-Risk Guarantee!

Building a new home, finishing out an addition, or converting a garage or sunroom into livable space? Those rooms need cooling too — and Gabe’s Priority AC Service handles new AC installation throughout San Antonio for exactly these situations. This is different from swapping out a failing system — installation means bringing cooling into a space that doesn’t have it yet.

We work directly with builders, contractors, and homeowners to design and install properly sized systems from the ground up — full ductwork runs, equipment sizing based on real load calculations, and clean, code-compliant installation. Every job is backed by our 365-Day, No-Risk Guarantee.

Installation is part of our full lineup of San Antonio HVAC services. If you’re instead replacing an old, failing system rather than adding cooling to a new space, see our AC replacement page — different service, different considerations. Not sure which one fits your project? Contact us and we’ll help you sort it out.

When You Need Installation, Not Replacement

Installation is for spaces that don’t currently have cooling. Here’s where it applies:

New Construction

Full HVAC system design and installation for new-build homes in San Antonio — sized correctly from the start based on square footage, insulation, window exposure, and layout. We work with builders on installation timelines that match the construction schedule.

Home Additions

A room addition often isn’t covered by your existing system’s capacity. We evaluate whether to extend the current ductwork or install a dedicated mini-split for the new space — whichever actually performs better for the addition’s size and layout.

Garage & Attic Conversions

Converting a garage, attic, or bonus room into living space means that room now needs real climate control — not a window unit. We install dedicated ductless or mini-split systems sized specifically for converted spaces.

Sunrooms & Enclosed Patios

Sunrooms take on significant heat load in San Antonio’s climate. We install systems designed to handle that extra load without straining your home’s main system.

Replacing an existing system instead? See our AC replacement page for repair-vs-replace guidance and pricing.

How Much Does AC Installation Cost in San Antonio?

New AC installation in San Antonio typically runs $4,000 to $12,000+, depending on system size, efficiency rating, and how much new ductwork needs to be run. Installations that require a full new duct system — like additions or conversions with no existing ductwork — run higher than installations tying into ducts that are already in place.

Tying into existing ductwork: $4,000–$7,000
Full new ductwork required: $7,000–$12,000+
Ductless mini-split (single zone): $3,500–$6,000
New-construction whole-home system: Quoted per project based on square footage and design

We provide a firm, itemized quote after walking the space — no guessing, no surprise change orders. We also offer flexible financing, including no-credit-needed plans.

 Trustindex verifies that the original source of the review is Google. My AC went out after the storm, but we were unaware. We called Gabe’s priority AC and they were able to accommodate me and come out that same day. The representative who took my call, the technicians that came into my home and the office staff were professional and kind. Urban and Isaiah were so courteous and professional while in my home and got my AC running. Thank you so much!

What’s Involved in a New Installation

Unlike a straightforward replacement, new installation involves design work upfront. Here’s what our process covers:

Load calculation — proper system sizing based on square footage, insulation, window exposure, and layout, not a generic rule of thumb
Ductwork design — routing and sizing new ducts for even airflow to every room, when full duct runs are needed
Equipment selection — matching the right system type and efficiency tier to the space and your budget

Electrical & permitting — coordinating any needed electrical work and pulling required permits
Clean installation — professional, code-compliant installation with minimal disruption to the rest of your home
System startup & testing — full performance verification before we consider the job done
