Air conditioning repairs in Harlow
Dripping, blowing warm air or showing a code you do not recognise? We fix air conditioning in homes and firms across Harlow and nearby, including units others fitted. Send us the make, the model and the code, and we can often narrow it down before arriving. We fix the cause, not just the symptom.

What do common air conditioning faults mean?
| Symptom | Likely cause | Meanwhile |
|---|---|---|
| Water coming from the indoor unit | Drain blocked or not falling | Turn it off and catch the drips |
| Fan runs but the air is not cold | Dirty filters or coil, lost refrigerant, or an outdoor unit fault | Check the filters |
| Frost on pipes or coil | Restricted airflow or low refrigerant | Turn it off to thaw |
| Code on the display | Depends on the code | Photograph it for us |
| Outdoor unit silent | No power, a breaker that has tripped, or a dead part | Check the isolator |
| Rattles or a stale smell | Loose fixings, a worn fan, or a dirty coil and drain | Note when it happens |
What can you check before ringing?
Try the easy things. Are the remote batteries fresh, is it set to the right mode, and is the set temperature below the room temperature? Look at the isolator outside and the breaker indoors. Rinse any filter that has turned grey. If a breaker trips again straight after you reset it, leave it down and mention it to us. An engineer needs to see that.
Noisy outdoor units and the neighbours
A rattle is better sorted before it turns into a dispute. Harlow Council's first advice on neighbour noise is to have a word with whoever is responsible, and it lists commercial premises among the noise it investigates. Worn fixings and damaged fans are often cheap to put right, and we can review where the unit sits while we are there.
What happens if there is a refrigerant leak?
Refrigerant work, including recovering or adding gas, is legally limited to people with the right F-gas qualification. Since the circuit is sealed, a low level means a leak, and topping up alone only postpones the next failure. If a legal leak check finds one, it has to be repaired as soon as possible and retested within a month. R410A systems are still repairable, so a leak need not mean a new unit.
Is it worth repairing, or time to replace?
That depends on age, the price of the part and how much better a new unit would be. Drains, fan motors and sensors usually justify a repair. A dead compressor on an elderly system often does not, particularly if parts are scarce. You get the options and a cost for each, then you choose. If replacing wins, see air conditioning installation.
Questions people ask
Do you work on all makes?
Tell us what you have when you ring. Common makes are rarely a problem, whereas parts for old or unusual units can take some finding.
Should I worry about a dripping unit?
It is only condensation, but it can stain a ceiling or reach electrics. Turn the unit off and keep a bowl under it until someone has looked.
Do I have to scrap an R410A system?
No. The ban applies to new single split systems under 3kg with a global warming potential above 750. Yours can keep running and be repaired.
