Frequently asked questions
How do I know it's the capacitor?
Classic signs are a condenser that hums but won't start, a fan that needs a push to spin, or no cold air with the compressor silent. We test to confirm before replacing.
How long does it take?
A capacitor change-out is typically under an hour once we've diagnosed it.
Will you check anything else?
Yes — we verify the contactor, capacitor rating, and compressor amp draw so the fix actually lasts.
