Aerotermia Repair
in Valencia
When the display shows a code you've never seen, the shower runs lukewarm or the outdoor unit has started rattling, you don't need a lecture on heat pumps — you need someone who can find the fault and name a price. Our English-speaking técnicos repair air-to-water systems of every major brand across Valencia, including plenty we never installed. Diagnosis comes first, then a fixed written quote, so parts are only fitted when they're genuinely needed.

A Repair Service That
Starts With the Fault
Half of the repair calls we take begin the same way: the system locked out overnight, the manual is somewhere in a drawer, and the company that installed it no longer answers the phone. We pick up where they left off — brand documentation on file, diagnostic tools in the van, and a habit of explaining what we find in plain English.
Send a photo of the error screen on WhatsApp before we visit. A code plus the brand name often narrows the fault to two or three causes, which means the right parts ride along on the first trip instead of the second.
- ✓ Error code and lockout diagnosis
- ✓ Hot water (ACS) faults traced
- ✓ Circulation pump replacement
- ✓ Expansion vessel and pressure fixes
- ✓ Sensor and thermostat faults
- ✓ Fan, bearing and noise problems
- ✓ Control board and wiring issues
- ✓ Certified refrigerant circuit work
- ✓ Leak tracing on the water side

How an Aerotermia Repair Works
From Symptom to Solution
Without Guesswork
A wrong guess in a repair costs you twice — once for the part that wasn't the problem and again for the one that was. So we work in a fixed order: symptom, evidence, diagnosis, quote. Only then do we open the toolbox.
Step 1
Describe
the Fault
Photo of the display, a note on the symptom, brand and rough age — WhatsApp is perfect for this.
Step 2
Remote
Triage
We match the code against brand documentation; simple settings slips are sometimes solved right there.
Step 3
On-Site
Diagnosis
We test pressures, sensors, pump and both circuits until the cause is proven, not assumed.
Step 4
Fixed
Repair Quote
You hear the fault in plain English and see a written price before any part is fitted.
Step 5
The Repair
Itself
Quality parts, correct pressures and torque, and a tidy workspace when we leave.
Step 6
Full-Cycle
Test
Heating, hot water and controls run through a complete cycle before we call it done.

The fault gets proven
before a single part is billed.

Who Calls Our Repair Line
Homes and Owners We Get Running Again
An avería never picks a convenient moment — guests landing on Friday, a cold snap over the holidays, a tenant messaging at breakfast. These are the situations we handle most.
Villas & Chalets
Bigger systems with underfloor circuits and pool tie-ins — more to test, and we test all of it.
Orphaned Systems
The installer retired, moved on or stopped replying? We take over units other firms fitted.
Holiday Rentals
Fast fault-finding for hosts whose booking calendar leaves no room for a cold-shower review.
Second Homes
You arrive after months away and the unit won't wake up — we coordinate visits around your trips.
Offices & Shops
For a business, a dead heat pump means lost trading time; we plan repairs to keep you open.
Symptoms We See Every Week
What Your Aerotermia Is Trying to Tell You
Five Complaints, Many Causes — One Method
A short-cycling compressor might be a clogged filter, a lazy sensor or a system that was never balanced; lukewarm ACS can be scale, a diverter valve or plain misprogramming. Symptoms overlap — which is exactly why we diagnose before we quote. If your system shows any of the patterns below, it's worth a call before the fault grows teeth.
- ✓ Error codes and repeated lockouts
- ✓ Lukewarm or fluctuating hot water
- ✓ Compressor short-cycling on and off
- ✓ Rattles, hums and grinding fan noise
- ✓ Water pressure quietly falling
- ✓ Rooms that never reach temperature
- ✓ Heavy frost on the outdoor unit
- ✓ Rising bills with no other explanation
Why Hand Us the Toolbox?
Repairs Done by People
Who Also Install
A técnico who only swaps parts sees components; an installer sees the system. Because we design and commission aerotermia ourselves, we recognise when a “faulty” unit is really a badly configured one — and that difference often saves our clients a repair they never needed.

- Fixed written repair quotes — no open-ended hourly work
- All major brands handled, including other firms' installs
- Certified, insured work on water and refrigerant circuits alike
- The fault and the fix explained in plain English

Repair or Replace?
When Fixing Stops Making Sense, We Say So
The Question We Answer Without a Sales Pitch
Most faults are worth fixing, full stop. But when a compressor fails on a unit whose spare parts are getting scarce, another repair can be money thrown after bad. In borderline cases we quote both routes — the repair and the replacement — with the trade-offs written down, and the decision stays yours. These are the factors we weigh out loud with you.
- ✓ Age and service history of the unit
- ✓ Compressor condition and wear
- ✓ Parts availability for your model
- ✓ Repair cost against a new system
- ✓ Any pattern of repeat faults
- ✓ Efficiency gap to current units
- ✓ Your plans for the property
- ✓ Support programmes open at the time

Repair Visits Across the Valencia Metro Area
Based in Torrent, Rarely Far Away
From our workshop on Saragossa street in Torrent, Paiporta and Catarroja are a short hop south, and Mislata and Xirivella sit just across the old riverbed — handy when a family is staring at a cold tank. North-side calls take us through Burjassot and Godella, while Manises and the airport corridor fill the gaps between. City addresses from the Marítims to Campanar round out a patch our vans criss-cross daily, so a diagnostic slot rarely has to wait long.

Local Insight
The First Cold Week of December Is Our Busiest — Here's Why
Valencia's climate lets heat pumps idle for half the year, and faults love idleness: seals dry, pressure seeps away, a sensor drifts — and nobody notices until the whole city switches its heating on in the same week. A system that "worked fine in March" meets December with a lockout. The fix is unglamorous: run a heating cycle once a month through the warm season, glance at the pressure gauge, and message us the reading if it keeps sliding. Ten quiet minutes in October routinely saves an emergency call in January.

Aerotermia Repair
Valencia FAQ
My aerotermia is showing an error code — what should I do?
Take a photo of the display and send it to us on WhatsApp with the brand name and roughly how old the unit is. Many codes point to a specific sensor, pressure or communication fault, so we often arrive knowing which parts to bring. Avoid resetting the unit over and over — a fault that keeps returning needs proper diagnosis, not another restart.
+
Do you repair aerotermia systems you didn't install?
Yes — most of our repair work is on systems fitted by other companies. We work on all major brands, including Daikin, Mitsubishi Electric, Panasonic, LG, Vaillant, Ariston and Baxi, and we're used to taking over installations whose original installer has vanished.
+
Why is my hot water lukewarm instead of hot?
The usual suspects are scale on the coil inside the cylinder, a drifting tank sensor, a sticking diverter valve or simply a hot water schedule set too low. Each has a different fix, which is why we test rather than guess — and lukewarm ACS is normally one of the quicker faults to resolve.
+
The water pressure on my system keeps dropping. Is that serious?
It shouldn't be ignored. Falling pressure usually means a small leak or a tired expansion vessel, and low pressure will eventually lock the heat pump out — often on the coldest morning of the year. Topping up hides the symptom for a while; finding the leak solves it.
+
My outdoor unit has become noisy. What could it be?
A new rattle or grind is usually the fan touching debris, a worn fan bearing, or mounts that have loosened and started transmitting vibration into the wall. None of these fix themselves, and a small bearing issue left alone can take the motor with it. A short video with sound is a great thing to send us.
+
Should I repair my old aerotermia unit or replace it?
Our honest rule: if the unit is in good general condition and the part is available at a sensible price, repair it. If the compressor is failing, faults keep repeating or parts are getting scarce, replacement usually serves you better. In borderline cases we put both options in writing and let you choose.
+
How much does an aerotermia repair cost in Valencia?
There's no hourly meter running. After diagnosis you receive a fixed written quote for the specific repair — part, labour and testing included — and we only proceed once you've approved it. The price depends mainly on the part needed, the brand and how accessible the unit is.
