Stegall HVAC Transforms Comfort in Birmingham Home: A Comprehensive Case Study


Stegall Heating, Cooling, Plumbing & Electrical, a trusted name in home comfort solutions, recently undertook a challenging project in a 30-year-old residence in Birmingham, AL. The homeowners, the Johnsons, were experiencing inconsistent temperatures, high energy bills, and frequent breakdowns of their aging HVAC system.

The Challenge

Upon inspection, Stegall’s technicians identified several issues:

  • An outdated and inefficient air conditioning unit
  • Poorly insulated ductwork
  • Inadequate zoning for the two-story home
  • An unreliable thermostat

The Johnsons wanted a solution that would provide consistent comfort, reduce energy consumption, and require minimal maintenance.

The Stegall Solution

After a thorough assessment, Stegall’s team proposed a comprehensive HVAC overhaul:

1. Installation of a new, high-efficiency AC unit
2. Replacement and proper insulation of ductwork
3. Implementation of a multi-zone system
4. Integration of a smart thermostat

The project began with the removal of the old AC unit. Stegall’s experienced technicians carefully installed a state-of-the-art, energy-efficient model, ensuring proper sizing for the home’s square footage and Birmingham’s climate.

Next, the team addressed the ductwork issues. They replaced damaged sections and added insulation to prevent energy loss. This step was crucial in improving overall system efficiency and eliminating temperature inconsistencies throughout the home.

To tackle the zoning problem, Stegall implemented a multi-zone system, allowing the Johnsons to control temperatures in different areas of their home independently. This customization significantly enhanced comfort levels and energy efficiency.

Finally, a smart thermostat was installed, providing the homeowners with precise control over their HVAC system. The new thermostat’s learning capabilities and remote access features offered additional convenience and energy-saving opportunities.


The impact of Stegall’s comprehensive HVAC solution was immediate and substantial:

  • Energy bills reduced by 30% within the first month
  • Consistent temperatures throughout the home
  • Improved indoor air quality
  • Enhanced system reliability with no breakdowns reported
  • Increased home value

The Johnsons expressed their satisfaction with the project, praising Stegall’s professionalism, attention to detail, and the noticeable improvement in their home’s comfort.
