Austin Whole-Home HVAC Upgrade with Zoning

When an Austin family wanted steadier temperatures and separate control for the primary suite, they turned to Radiant Plumbing & Air Conditioning. Our team installed a new 5-ton Amana gas system, added a two-zone setup with an extra thermostat in the master bedroom, and brought the home up to current code—inside and out.

Job Overview

  • Location: Austin, TX
  • Client Type: Residential homeowner
  • Scope: Full HVAC system replacement with new zoning and controls
  • Equipment Installed: Amana 5-ton horizontal gas system (matching furnace, coil, and outdoor unit), communicating thermostat, AprilAire filter base, Solaris IAQ kit
  • Why It Mattered: The home needed better airflow balance and room-by-room comfort. Zoning and a modern, right-sized system provide quieter operation, improved efficiency, and targeted temperature control.

What We Found

The existing setup did not have zoning, which led to hot and cold spots—especially between living areas and the primary bedroom. Return air and supply distribution were due for an upgrade, and outdoor components needed new electrical and mounting to meet current standards.

The Solution

Radiant’s crew installed a new Amana 5-ton horizontal gas system and completed a full code-compliant change-out:

  • Zoning & Controls: Added a two-zone system with a new thermostat in the master bedroom. Ran new communicating wire to the outdoor unit. Installed and neatly mounted a new zone board with dedicated wiring for each section of the home.
  • Air Distribution: Built a 21″ × 21″ × 48″ main supply plenum. Ran two 16″ trunk ducts with zone dampers to two 19″ × 19″ × 48″ sub-plenums. All joints sealed and strapped for long-term performance.
  • Indoor Upgrades: Added an AprilAire filter base for better filtration and serviceability. Installed a Solaris kit to enhance indoor air quality.
  • Outdoor Upgrades: Set a new equipment pad, disconnect, and electrical whip for safe, clean installation.
  • Site Logistics: Coordinated attic access and equipment handling around the existing ladder opening as discussed with the homeowner.

The system started up cleanly with no issues, and the installation was prepared for city inspection. Equipment registration and 10-year parts & labor warranty were completed.

The Results

With zoning in place, the family can set the primary bedroom separately from shared spaces for comfort day and night. The upgraded distribution and sealed duct connections improve airflow and efficiency, while the Solaris kit and high-quality filtration help keep air cleaner. The result: steadier temps, quieter operation, and a system built for reliable service for years to come.

But, How Long Does It Take to Install a New Furnace?

Every home and heating setup is a little different. The furnace installation time depends on the type of equipment you choose, the layout of your existing mechanical systems, and how accessible the workspace is. Here’s what can influence your installation day schedule:

Type of furnace

Furnace Type Typical Installation Time Notes
Gas furnace 4–8 hours Most common in San Antonio homes. If a gas line needs to be added or relocated, expect an extra 2–4 hours.
Electric furnace 3–6 hours Faster to install if your electrical panel has available capacity. A panel upgrade or new circuit adds coordination time.
Oil furnace 6–12 hours or more Rare in Central Texas. Installation involves added work for venting and fuel lines—call Radiant for specific timelines.

What You Can Expect on Installation Day

When you schedule a residential furnace installation with Radiant, you’ll get a well-coordinated process that runs smoothly from arrival to final test.

Before we arrive

  • Clear a few feet of space around your furnace and along access paths.
  • Move fragile items nearby, and secure pets or children in another room.
  • Ensure gas shutoffs and electrical panels are easy to reach.
  • If you’re upgrading to a smart thermostat, have Wi-Fi info handy.

During the installation

  • Our technicians walk you through the plan before starting.
  • We use floor coverings, drop cloths, and safety checks before removing the old unit.

Replacing a blower motor in a furnace is a detailed and technical job that’s best left to a licensed professional. It involves turning off power and gas, carefully removing the furnace panels, disconnecting wiring, unmounting the old motor, installing the correct replacement, reconnecting all components, and thoroughly testing the system for safe, efficient operation.

Because the blower motor is essential to your home’s airflow and overall heating performance, improper installation can lead to poor comfort, energy waste, or even safety risks.

At Radiant Plumbing & Air Conditioning, our licensed technicians have the training and tools to diagnose blower motor issues and replace them safely and efficiently. Trusted across Texas since 1999, Radiant delivers expert repairs that protect your furnace and keep your home warm and comfortable.

A whole home air filter is designed to clean the air throughout your entire house by capturing airborne particles like dust, pollen, and pet dander as they pass through your HVAC system. Installed directly into your system’s return air duct, these filters work quietly in the background to reduce indoor allergens and improve overall air quality. Unlike portable units that only treat a single room, a whole house filter protects every space connected to your ductwork. At Radiant Plumbing & Air Conditioning, we install high-quality filtration systems tailored to your home’s needs—so you and your family can breathe easier, every day.
