Air conditioner making noise: repair in Valencia
A healthy unit sounds like a whisper. When the buzz, the rattle or the through-the-wall vibration appears, something is asking for attention — and it is usually cheaper now than when the noise becomes a breakdown.
We reply in writing — no calls unless you ask for one.
Quick summary
AC noises and their typical cause: rattling — dirty or unbalanced blower; deep buzz — mounts or compressor; squeal — bearings; gurgling — drain or low gas; façade vibration — dead anti-vibration mounts. Diagnosis in Valencia from €60. WhatsApp: +34 617 307 409.
What does each AC noise mean?
A trained ear distinguishes a lot: a rhythmic rattle points to a dirty blower or touching blades; a deep buzz that grows over the years, to worn mounts or a tired compressor; a sharp squeal, to dry bearings; gurgling, to air in the drain or low gas; and the vibration your neighbour feels in their bedroom, to dead anti-vibration mounts or loose anchoring. Each cause has its own fix — and its own price.

Why us
Silence, methodically
Blower balanced and cleaned
The number-one cause of rattling is solved with a deep clean and a play check.
Real anti-vibration work
New pads and reviewed anchoring — the vibration stops travelling through the structure to the neighbour's bedroom.
Compressor judged on data
If the buzz comes from the compressor, we measure current and starting behaviour — and tell you in writing how much life it has left.
Relocation if needed
When the outdoor unit sits where it never should have, we quote moving it somewhere better.

FAQ
FAQ about noises
Why does my AC make noise on start-up?
A brief click or rattle at start-up is usually plastic expansion or the blower touching accumulated dirt; if the noise continues while running, suspect an unbalanced blower, bearings or mounts. Diagnosis pins it down in one visit.
The outdoor unit vibrates and disturbs the neighbour — fixable?
Almost always: new anti-vibration pads, corrected anchoring and, if the bracket is badly placed, unit relocation. It is one of the most rewarding fixes — neighbourly peace returns in a single visit.
Does a new noise mean a serious fault?
Not always, but it is a cheap early warning: a dirty blower or a dry bearing costs little today and much more once it breaks another part. Better to measure now.
How many decibels is normal?
A modern indoor unit at medium speed runs 24–35 dB — low conversation. If yours is clearly louder or the tone has changed, that is not "just how ACs sound": it is a symptom.
Can you move the outdoor unit somewhere else?
Yes — we relocate badly placed units with new routing, vacuum-tested lines and resolved drainage. With a written fixed figure before we start.
