What's wrong with your air conditioning?
Most of the alerts in Cuatro Caminos start with a simple symptom: it doesn't cool, it drips, it smells bad, or it stops shortly after starting. The important thing is not to confuse the symptom with the cause. A unit can fail due to lack of refrigerant, leak, blocked drainage, sensor, inverter PCB, fan, poor installation, or lack of maintenance.
Not cooling or cooling poorly
We check filters, battery, ventilation, pressure, compressor consumption, and possible leak before recharging refrigerant.
It is leaking water from the indoor unit.
We check the tray, siphon, drain pipe, condensate pump, and slope of the layout, especially in ducted systems.
It turns on and off
It may be due to electronic protection, sensor, fan, inverter PCB, high pressure, or lack of heat exchange.
Makes noise or vibrates
We analyse the fan, turbine, mounts, bearings, outdoor unit, and possible resonances on facades or inner courtyards.
Indicate a fault code
We interpret faults from Daikin, Mitsubishi, LG, Panasonic, Fujitsu, Toshiba, Samsung, Haier, and other common brands.
Smells bad when starting
It is usually related to humidity, biofilm, dirty tray, saturated filters, or poorly resolved drainage. We clean and correct the cause.
Why choose Uniclima to repair your air conditioning in Cuatro Caminos
An air conditioning repair should not be based on trial and error with parts. In Cuatro Caminos, we find many installations in chalets, semi-detached houses, and ducted homes where access, drainage, and the location of the outdoor unit affect the fault. That's why we work methodically: measure, diagnose, and repair the cause.
Diagnosis before quotation
We measure pressures, temperatures, electrical consumption, the state of sensors, fans, PCB, drainage, and air return. This way, we distinguish whether the problem comes from a leak, dirt, electronics, ventilation, or installation.
Experience in ductwork and multisplit systems
In homes in Cuatro Caminos, ducted systems in false ceilings, returns in hallways, outdoor units in patios or on rooftops, and long refrigerant lines are common. We adapt the intervention to the actual installation, not a generic solution.
Multibrand repair
We work with Daikin, Mitsubishi Electric, LG, Toshiba, Panasonic, Hitachi, Fujitsu, Samsung, Haier, and other common brands in the residential and small commercial market.
Root cause, not a temporary fix
If there is a leak, it's not enough to recharge gas. If there is dripping, it's not enough to blow the pipe. We check the source to prevent the fault from reappearing in a few weeks.
Air conditioning repair services in Cuatro Caminos
We attend to domestic and small business faults in Cuatro Caminos, from a wall-mounted split unit that doesn't cool to duct systems with leaks, multisplit units with communication faults, or inverter units that lock up when starting.
Split air conditioning repair
We inspect wall-mounted units that do not cool, leak water, make noise, stop, or display fault codes. We check filters, coil, fan, PCB, sensors, consumption, and working pressure.
Request diagnosisDucted air conditioning repair
Especially useful in chalets and semi-detached houses in Cuatro Caminos with false ceilings, long returns, or unbalanced grilles. We check drainage, tray, siphon, dampers, flow rate, supply, and return.
Request diagnosisRepair of multisplit and inverter
We diagnose communication faults, intermittent errors, inverter PCBs, expansion valves, fans, and imbalances between indoor units.
Request diagnosisLeak detection and refrigerant charging
Before charging gas, we locate the source of the leak using leak tests, electronic detector, nitrogen, and deep vacuum when applicable. The charging is done by weight and according to the manufacturer's specification.
Request diagnosisLeaks, bad odours, and blocked drains
We clean trays, siphons, condensate pipes, and drainage pumps. We also check slopes and access points to reduce recurrences.
Request diagnosisPreventive maintenance
Cleaning of coils, filters, fan, disinfection of tray, electrical inspection, performance check, and early detection of problems before the hotter months.
Request diagnosisCommon faults in air conditioning units in Cuatro Caminos
In Cuatro Caminos, leaks in ducted systems, leaks in long refrigerant lines, communication failures in multisplit systems, and blockages due to dirt in exposed outdoor units are common. Each fault requires a different check; therefore, we do not recommend recharging gas, changing a PCB, or replacing a compressor without prior diagnosis.
The air conditioning is not cooling
It may be due to saturated filters, dirty battery, lack of refrigerant, leak, weak fan, misaligned sensor, or low compressor performance. We measure temperatures, pressure, consumption, and air flow to distinguish between a lack of maintenance and a real fault.
It leaks water through the false ceiling or the indoor unit.
It is usually related to a dirty tray, blocked siphon, pipe without slope, failing condensate pump, or poorly resolved air return. In ductwork, we check the entire layout to ensure the problem does not reoccur.
Communication error or inverter fault
In multisplit and inverter systems, we check the power supply, wiring, outdoor PCB, indoor PCB, IPM module, sensors, fans, and communication errors between units.
Refrigerant leak
A gas charge without locating the leak is a temporary solution. We check flares, valves, welds, heat exchangers, and refrigerant lines before performing vacuum and charging by weight.
Bad smell when turning on the unit
It usually appears due to accumulated humidity, biofilm, dirty filters, contaminated tray, or poor drainage. We clean, disinfect, and check condensate drainage.
High pressure due to dirty outdoor condenser
Symptoms: the unit cools poorly, stops during the hottest hours, the outdoor unit works under strain, or a high pressure error appears. In patios, roofs, and exposed facades of Cuatro Caminos, dust, pollen, and lack of cleaning reduce the thermal exchange of the condenser. We clean the outdoor coil, check the fan, working pressure, and discharge temperature to prevent compressor overstrain.
Does your equipment exhibit any of these symptoms?
Tell us the brand, type of equipment, and fault. We will guide you before dispatching the technician.
How we work when you call us
We collect the symptom
We ask for the brand, type of equipment, location of the indoor and outdoor unit, main symptom, and if any fault code appears.
Revisamos la instalación
The technician checks access, drainage, filters, ventilation, electrical supply, visual condition, and operating conditions.
We measure before deciding
We take data on pressure, temperature, consumption, flow rate, sensors, and compressor response to locate the cause with precision.
We explain the repair.
We indicate what the fault is, what solution we recommend, and what alternative exists if the equipment is old or the repair is not worthwhile.
We tested the equipment functioning.
After intervention, we check cooling, drainage, stability, consumption, and absence of errors to close the service call correctly.

Air conditioning in Cuatro Caminos: what we usually find in homes
Cuatro Caminos is one of the most densely populated neighbourhoods in Madrid: tall residential blocks and very large communities in the Tetuán district. In many interventions, we find ducted systems in false ceilings, multisplit systems for several rooms, outdoor units in patios or on rooftops, and longer refrigerant pipe runs than usual. These conditions influence the diagnosis: a simple wall-mounted split is not inspected in the same way as a ducted system with centralised return.
Ducts in a false ceiling
Require checking drainage, return, flow, grilles, and access to the tray.
Outdoor units exposed
Dust and lack of cleaning reduce thermal exchange and can increase working pressure.
Long refrigerant lines
It is advisable to check the load, tightness, insulation, and performance drop.
Modern inverter equipment
They demand a more precise electrical and electronic diagnosis before replacing components.
