When your AC starts falling behind in a Texas home, it usually shows up fast. Long run times, uneven cooling, and rooms that just never quite feel right. This Pflugerville homeowner was ready for a system that could actually keep up. Radiant replaced the existing setup with a new air conditioner and furnace, while also upgrading airflow and adding zoning to better manage different areas of the home. The goal wasn’t just a bigger system, but one that runs more efficiently, distributes air properly, and gives the homeowner more control. By the end of the install, the home was set up for more consistent cooling and better day-to-day comfort.

Job Overview

  • Location: Pflugerville, TX
  • Client Type: Residential
  • Scope: Full heating and cooling system replacement with zoning and airflow improvements
  • Equipment Installed: Two-stage air conditioner, gas furnace, indoor coil, zoning system, UV air purification device
  • Additional Work: New supply plenum, sub-plenums, zone dampers, zone control panel, bypass installation, electrical breaker verification
  • Why It Mattered: The homeowner now has a system that cools more evenly and handles the demands of a Texas home more effectively.

What We Found

The existing system was no longer keeping up with the cooling needs of the home. In Central Texas, that often means the system is either undersized, aging, or struggling to move air effectively throughout the house.

Without proper airflow and zoning, even a functioning system can leave certain areas warmer than others, especially during peak summer temperatures.

The Solution

Radiant installed a new two-stage 4-ton air conditioning system paired with a new gas furnace to better match the home’s cooling demands. To improve how air is distributed, the team added a new supply plenum, sub-plenums, and zoning components including dampers and a control panel.

A bypass system was also installed to help manage airflow between zones, and a UV air purification device was added to support indoor air quality. The team confirmed system operation, checked electrical components, and ensured everything was running properly before wrapping up the job.

The Results

The home now cools more evenly and responds better to changing temperatures throughout the day. With a properly sized system and updated airflow design, the homeowner can expect more consistent comfort without the system working as hard.

The addition of zoning and air quality improvements also gives the homeowner more control over their environment, making the system easier to manage and more effective overall.
