If your air conditioner runs but does not cool in Calpe, you need an experienced air conditioning technician who can work out whether the problem is airflow, refrigerant, the controls, or the condition of the system itself.
100% Plumbing is based in Calpe and diagnoses airflow, refrigerant, maintenance and air conditioning system faults across the Marina Alta.
Start by feeling the airflow at the vent. Weak airflow and cold-but-not-cold-enough air are two different problems. If the air is moving properly and still is not cold, the fault is not the filter, and changing settings will not fix it.

Why is my air conditioner running but not cooling?
A unit that runs without cooling is doing its job on the outside and failing somewhere you cannot see. The usual causes are:
- clogged filters;
- restricted airflow;
- dirty coils;
- low refrigerant;
- thermostat or control faults;
- drainage problems;
- electrical or sensor faults;
- an ageing or poorly maintained system.
Airflow is the quickest way to narrow it down. If airflow is weak, the system cannot circulate cool air properly. If airflow seems normal and the air still is not cold, the fault lies elsewhere and needs proper diagnosis.
What can I check before calling a professional?
There are a few things worth ruling out first, and a couple that are a waste of time.
Worth checking yourself
- that the unit is in cooling mode;
- that the set temperature is below the room temperature;
- the accessible filter, for dust and blockage;
- that vents and indoor airflow are not obstructed;
- cleaning or replacing a dirty filter, following the manufacturer’s instructions.
Will not fix an underlying fault
- changing the settings repeatedly;
- switching the system off and on again;
- dropping the temperature further than needed.
If cooling does not return after those checks, the system needs looking at. Our aircon maintenance service covers filters, coils, drainage and the wider condition of the unit.
Does an air conditioner that is not cooling need regassing?
Not automatically, and this is where money often gets spent for nothing. Low refrigerant does reduce cooling performance, but so do several other faults, and a unit can be topped up and still not cool.
There is also a second question behind the first: refrigerant does not simply run out. If the level is low, something let it go, and that is worth finding before refilling. Depending on the diagnosis, regassing may be part of the fix rather than the whole fix.
When does poor cooling need professional attention?
Some of these mean reduced performance, and some mean the system is developing a fault that will get worse.
Do not leave it
- ice forming on the unit or the pipework;
- water leaking from the indoor unit;
- unusual noises or smells;
- the system switching itself off repeatedly.
Book a service
- the room stays warm while the unit runs;
- airflow is still weak after checking the filter;
- cooling performance has noticeably dropped;
- the same problem keeps coming back.

Repair or replacement: which is better?
A cooling fault does not automatically mean a new unit. It depends on the age and the history of the system.
Repair usually makes sense when
- the problem is isolated;
- the system is otherwise in reasonable condition;
- it has been serviced and performs well between faults.
Replacement becomes more practical when
- the unit is old;
- it breaks down repeatedly;
- it performs poorly even after servicing;
- it no longer meets the needs of the property.
Notre air conditioning service covers both: diagnosis and repair of existing systems, and installation where replacement is the better option.
Why air conditioning problems matter in Calpe and the Marina Alta
Systems here work hard. During the hot months they run for long stretches in villas, apartments, holiday rentals, businesses and homes, and a unit that is not cooling properly is both uncomfortable and expensive: it keeps drawing power without delivering the result.
In a holiday rental the problem lands on a guest the same day. And because the heaviest demand arrives all at once in summer, a fault that was developing quietly in spring tends to show up at the worst possible moment. Regular maintenance is what catches those early.
