FAQ: AC Replacement

Common Questions About New AC Systems in Lewisville

  • How much does a new AC cost in Texas?

    The cost of a new AC system in Texas depends on the size of your home, the efficiency level you choose, and any ductwork or electrical upgrades needed. Smaller homes with straightforward installs may fall on the lower end of the range, while larger homes or high-efficiency systems naturally cost more. We provide personalized estimates after evaluating your home so you’re not relying on rough guesses. During your quote, we’ll break down equipment, installation, and any optional add-ons so you know exactly what you’re paying for.

  • How long does AC installation usually take?

    Most standard AC installation and replacement projects can be completed in a single day under normal conditions. More complex jobs that involve significant ductwork changes, relocation of equipment, or additional electrical work may take longer. Before we begin, we’ll let you know what to expect and how long we anticipate being in your home. Our goal is to work efficiently while still taking the time needed to do the job the right way.

  • What are the benefits of a high-efficiency AC system?

    High-efficiency systems are designed to use less energy while delivering more consistent, comfortable cooling. Over time, this can lower your monthly utility bills compared to an older, less efficient unit running under the same conditions. Many high-efficiency models also offer quieter operation and better humidity control, which is a big plus in our climate. When we discuss options, we’ll help you weigh upfront cost against long-term savings and comfort.

  • Can you replace my AC using my existing ductwork?

    In many homes, we can install a new AC system that uses your existing ductwork. However, if the ducts are damaged, poorly sized, or leaking, they can reduce the performance of your new unit and waste energy. As part of the replacement process, we inspect your ducts and recommend repairs or air duct replacement if needed to protect your investment. When appropriate, we may also discuss attic insulation improvements to support better overall efficiency.

  • Do you offer financing for AC installation in Lewisville?

    Yes, we offer financing options for AC installation Lewisville homeowners can use to make new systems more attainable.
