It’s pretty common in Austin to hear our customers complain that the upstairs rooms aren’t as cool as their downstairs ones. This Cedar Park homeowner was dealing with a system that just wasn’t keeping up across both floors, and it showed in uneven temperatures and limited control. Radiant stepped in to replace the existing setup with a new heat pump and furnace system, while also reworking the airflow and adding zoning to better manage each part of the home. We updated ductwork, replaced grilles, and installed smart controls to give the homeowner more say in how their home feels day to day. The end result is a system that’s not just new, but actually works the way a two-story home needs it to.
Job Overview
- Location: Cedar Park, TX
- Client Type: Residential
- Scope: Full heating and cooling system replacement with ductwork updates and zoning
- Equipment Installed: Dual-fuel heat pump and gas furnace system, indoor coil, smart thermostat, zoning controls, UV light, surge protection, filter base
- Additional Work: Accessible ductwork replacement, upstairs supply buckets, supply and return grilles, drain line cleanup, copper line insulation, condenser pad, disconnect box, attic insulation planned as follow-up
- Why It Mattered: The homeowner gained a more reliable, efficient, and easier-to-control comfort system for a two-story home.
What We Found
The home had an older heating and cooling setup serving a two-story layout. The existing equipment was replaced with a more advanced dual-fuel system, and the project also called for better airflow, updated grilles, zoning, and new control wiring.
For a larger or multi-level home, airflow and control can make a big difference. Without the right equipment and duct setup, some rooms may feel too warm, too cold, or harder to manage from one thermostat.
The Solution
Radiant replaced the existing outdoor cooling equipment, furnace, and indoor coil with a new heat pump and gas furnace system. The team also added smart thermostat controls, zoning equipment, and two round dampers to help manage comfort across different parts of the home.
Inside, the crew updated the platform area, sealed the return chamber where needed, installed a new filter base, added a UV light in the supply plenum, cleaned up drain lines, and reinsulated copper lines. Outside, they replaced the condenser pad, disconnect box, and whip, added surge protection, and protected new low-voltage wiring with conduit.

System readings during setup help confirm the new heat pump is running the way it should.

The Results
The homeowner now has a new dual-fuel comfort system designed to heat and cool the home with more control. With updated ductwork, grilles, zoning, and smart controls, the home is better set up for reliable comfort across both floors.
The added UV light, surge protection, filter base, and line cleanup also helped support cleaner operation and long-term system protection.
