AC making noise
Rattling, buzzing or grinding sounds.
What usually happens next
Tell us what you are seeing, hearing or smelling and which room or unit is affected. We turn that into a structured job so the technician who accepts it arrives expecting the right kind of work — not a blind visit. Diagnosis and pricing stay with the provider; we do not guess repairs on their behalf.
If the situation is unsafe — burning smell, sparks, water near electrics — switch the unit off at the breaker and mark the request as an emergency.
