    FAQs — Answered Honestly

    Most fixes take 1–3 hours. Full system replacements can often be done in a day. We'll always give you a timeline up front.

    If your system is 10–15 years old, needs frequent repairs, or isn't cooling efficiently, a new unit could save you money in the long run. We'll lay out the math — no pressure.

    Yes. It helps prevent surprise breakdowns and keeps your warranty valid. Think of it like an oil change for your home's comfort.

    Could be duct issues, insulation problems, or a failing system. We can diagnose the root cause and help you balance your home's cooling.

    No — A/C systems don't consume refrigerant. If it's low, there's a leak that needs fixing. We'll find it and stop it at the source.

    Most homes feel good between 74–78°F in summer. Higher settings save energy — but we'll help you dial in comfort and efficiency.
