FAQs About AC Installation

  • How long does installation take?

    Most standard installations take one full day. Larger systems or custom ductwork projects may take 2–3 days.

  • Do I need to replace my ductwork?

    Not always. We’ll inspect your existing ductwork to ensure it’s properly sized and sealed. If needed, we’ll make recommendations for airflow and efficiency.

  • Can I install AC in a home without existing ducts?

    Yes. Ductless mini-split systems are ideal for homes without ducts, including historic properties, additions, or single-room installations.

  • What’s the warranty on a new AC system?

    Most systems come with a 10-year manufacturer warranty, and we back all our workmanship. Extended warranties are also available.
