Greater San Antonio AC Installation & Replacement

When your old system can no longer keep up—or energy bills are climbing with little return—it may be time to think about a new unit. As a seasoned AC contractor and ac service contractor in Greater San Antonio, Christianson designs and installs central air conditioning systems tailored to your home, lifestyle, and budget.

Our air conditioning contractor team considers several factors before recommending a new system:

  • Home size and layout: Square footage, ceiling height, and room configuration.
  • Existing ductwork: Condition, sizing, and airflow balance.
  • Efficiency goals: Desired SEER ratings and comfort features (two-stage, variable-speed).
  • Indoor air quality options: Compatibility with filters, dehumidifiers, and IAQ add-ons.
  • Budget and financing: Upfront cost, operating cost, and available payment options.

We work with leading equipment manufacturers (and coordinate with A.O. Smith water heaters, Noritz tankless water heaters, Rinnai tankless water heaters, and Nugen Systems water softeners when projects overlap) to provide complete, integrated comfort solutions.

What a typical AC installation or replacement visit includes:

  • Removal and proper disposal of your old equipment.
  • Installation of the new indoor and outdoor units and any necessary line sets.
  • Connection to existing ductwork, with recommendations for corrections if needed.
  • Electrical and thermostat hookups, including smart thermostats when requested.
  • Start-up, testing, and a walk-through of system features and basic maintenance steps.

For plumbing and HVAC new construction, remodel, and retrofit work, we offer free estimates after reviewing your plans. For general replacement jobs, we do not offer free estimates, but many standard installations can be quoted clearly before work begins.
