Air conditioner not cooling? We diagnose it in Valencia
It blows air, but the room never drops below 27. Before accepting the classic "must be the gas, that's €150", let someone measure it: half of all "no gas" units have a different fault — and refilling without repairing means paying twice.
We reply in writing — no calls unless you ask for one.
Quick summary
If your AC is not cooling, the usual causes are: clogged filters, gas lost through a leak, a dirty or blocked outdoor coil, a failed sensor, or a weakening compressor. Full instrument diagnosis in Valencia from €60, deducted if you accept the repair. WhatsApp: +34 617 307 409.
Why is the air conditioner not cooling? The 5 real causes
In order of frequency: filters and blower so clogged they choke the airflow; missing refrigerant — always through a leak, gas does not "get used up"; a dirty or obstructed outdoor coil that cannot reject heat; sensors or a PCB cutting the compressor early; and the compressor itself reaching the end of its life. Each shows up in a different measurement — which is why serious diagnosis uses instruments, not intuition.

Why us
A diagnosis that is measured, not guessed
Pressures on the gauge
The circuit reading separates a real leak from a lying sensor — without blind dismantling.
Compressor current checked
The clamp meter exposes a tired compressor before it dies in mid-August.
The leak, located
If gas is missing, we find where it went — recharging without repairing throws €150 away every summer.

FAQ
FAQ: air conditioner not cooling
Why does my AC blow air but not cool?
Most frequent causes: clogged filters or blower, gas missing through a leak, a dirty outdoor coil, a failed sensor or a tired compressor. Each has its own measurement — instrument diagnosis tells them apart in one visit.
Could it just need gas?
It could — but gas is not consumed: if it is missing, there is a leak. Refilling without locating it means paying for another refill next summer. Our protocol finds the leak before adding refrigerant.
How much does it cost to find out what is wrong?
The full diagnosis starts at €60 and includes pressures, currents, temperature delta and inspection. If you accept the repair, it is deducted in full.
Should I clean the filters myself before calling?
Yes — take the filters out of the indoor unit and wash them with water: it is free and solves a share of cases. If it still will not cool with clean filters, the cause is deeper and needs measuring.
What if the compressor is dead?
We give you both figures in writing: replacing the compressor or replacing the unit. Over 10 years of age, replacement usually wins — but the decision is yours, with the numbers in front of you.
