A homeowner in Round Rock was ready to upgrade their aging HVAC system after dealing with inconsistent temperatures and reliability concerns. Our Radiant team installed a full 5-ton variable Trane gas system in the attic, replacing key components like the thermostat and disconnect. The result was a more efficient, dependable system built to handle Texas heat with ease.
Job Overview
- Location: Round Rock, TX
- Client Type: Residential
- Scope: Full HVAC system replacement in attic (horizontal configuration)
- Equipment Installed: Trane furnace, evaporator coil, and condenser
- Additional Work (if any): Thermostat replacement, disconnect pad replacement
- Why It Mattered: The homeowner now has a reliable, energy-efficient system designed to keep their home comfortable year-round
What We Found
The existing system had been in place for some time and was no longer keeping up with the home’s cooling and heating needs. Like many homeowners experience, uneven temperatures and reduced efficiency made it harder to stay comfortable, especially during peak summer months. The setup in the attic also meant accessibility and proper configuration were important for long-term performance.
The Solution
Our team installed a complete 5-ton variable Trane gas system in the attic, designed for high efficiency and consistent airflow. We carefully removed the old equipment, set the new furnace and coil in the existing horizontal configuration, and installed the outdoor condenser. We also replaced the thermostat for better system control and upgraded the disconnect pad for safety and reliability. Once everything was connected, we tested the system thoroughly to ensure proper operation, airflow, and performance.
