A Full HVAC System Upgrade Delivers Reliable Comfort in San Antonio

After more than a decade of use, this San Antonio homeowner’s heating and cooling system was no longer delivering consistent comfort or efficiency. With both the furnace and air conditioner nearing the end of their lifespan, the Radiant team completed a full HVAC system installation to replace outdated equipment and restore dependable performance throughout the home. The upgrade provided improved airflow, quieter operation, and peace of mind heading into future seasons.

Job Overview

  • Scope: full HVAC system replacement
  • Equipment Installed: Goodman gas furnace, Goodman air conditioner, matching indoor coil
  • Additional Work (if any): system testing, equipment registration, permit coordination, quality control inspection
  • Why It Mattered: replacing the full system improved comfort, efficiency, and long-term reliability for the homeowner

What We Found

The existing furnace and air conditioning system were approximately 16 years old and showing clear signs of wear. Aging components were reducing efficiency and increasing the risk of breakdowns, especially during extreme summer heat. The homeowner needed a solution that would support consistent comfort without ongoing repair concerns.

The Solution

Our team removed the old furnace and air conditioner and installed a new, properly matched Goodman full system designed to improve efficiency and airflow. The installation included setting the new gas furnace, installing the indoor coil and outdoor condenser, reconnecting ductwork and utilities, and completing system testing to ensure safe and reliable operation. Final quality checks, equipment registration, and permit closure confirmed the system was installed to meet both performance and local code standards.
