Free Energy Audits for Westlake Homes: Cut Energy Bills, Boost Comfort & Upgrade Smarter

If your Westlake home is ten years old or more, there’s a good chance it’s using more energy than it should.

Between large floor plans, multi-level layouts, aging ductwork, and Texas heat, many Westlake homes quietly lose comfort and money through inefficiencies you can’t always see. That’s why a free home energy audit is one of the smartest first steps you can take toward lower utility bills and a more comfortable living space.

At McCullough Heating & Air Conditioning, we help Westlake homeowners uncover hidden energy losses and create a clear path toward meaningful upgrades,  starting with a FREE professional energy audit for Austin Energy customers. 

What Is a Home Energy Audit?

A home energy audit is a comprehensive evaluation of how your house uses (and loses) energy. Our trained technicians assess your entire home system, including:

• Heating and cooling performance
• Ductwork efficiency and air leakage
• Attic insulation levels
• Home envelope sealing
• Indoor air quality concerns
• Overall comfort issues and energy usage patterns

Think of it as a full wellness check for your home. Instead of guessing where problems exist, you get real data and actionable recommendations.

Common Energy Problems in Westlake Homes

Many homeowners are surprised to learn just how much energy escapes through everyday issues like:

• Underperforming HVAC systems
• Inefficient or leaking ductwork
• Inadequate attic insulation
• Air leaks around doors, windows, and walls
• Poor home sealing
• Rising energy bills with no clear explanation

These problems don’t just impact your utility costs; they affect comfort, humidity control, and indoor air quality throughout your home.

An energy audit helps pinpoint exactly where improvements will make the biggest difference.
