Air conditioning repairs in Croydon
Has the air conditioning in your Croydon home or business stopped cooling, started dripping or begun flashing an error code? We repair systems across the borough whoever fitted them. We find the fault before any part is ordered, give you the price, and tell you when a repair has stopped being worth it.
Report a breakdown
Name, number and postcode. We ring you to go through it.
- Any make, any installer
- The leak is found, not just topped up
- Plain advice on repair or replace
What can you check before you ring?
- Is the remote in cooling mode, and are its batteries alive?
- Has the breaker in the consumer unit, or the isolator by the outdoor unit, tripped?
- Are the filters furred up? Washable ones slide out and rinse clean.
- Is anything stacked against the outdoor unit, or has a cover been left on it?
A breaker that trips a second time after a reset should stay off until we have looked at it. Leave the casing closed and keep away from the copper pipework.
What do the common symptoms point to?
| What you see | Usual cause |
|---|---|
| Water dripping from the indoor unit | Blocked condensate drain or a dirty coil |
| Fan runs, air is not cold | Clogged filters, a low charge or a failing compressor |
| Ice on the pipes or the coil | Starved airflow or a leak |
| A code on the display | Depends on the make, so photograph it |
| Rattling, buzzing or grinding | Loose panel, debris in the outdoor fan or a failing motor |
These are starting points. Gauges and a thermometer on site settle it.
Why won't you just regas it?
Because refrigerant does not get used up. If the charge is low, it has leaked, and it will leak again after a top-up. The money goes with it, and so does a greenhouse gas. The repair is finding the leak and fixing it, then recharging, and by law that work belongs to a qualified F-gas engineer. Source: GOV.UK.
When does replacement make more sense?
When a compressor has failed on an old unit, when the same fault keeps returning, or when the refrigerant is one that is being phased out. New single splits holding under 3kg of a gas with a global warming potential above 750 have been banned from sale since 2025. You can still repair what you own, but parts and gas for older systems get scarcer and dearer. We price the repair and the replacement side by side. Source: GOV.UK guidance.
What should you have ready when you call?
The make and model from the label on the indoor unit, any code on the display, when the fault began, and whether it happens in both heating and cooling. A photo of the outdoor unit and where it sits saves a visit. Tenants should let the landlord know, since the landlord may own the system and need to approve the work.
Questions people ask
Is there a call-out charge?
We tell you about any charge on the phone before anyone is booked, so there is no surprise on the day.
Can you fix a cheap unit bought online?
If parts exist, usually. Send the model number and we will find out before you pay for a visit.
The indoor unit is dripping onto the carpet. What do I do?
Switch it off at the remote and the isolator, catch the water, move anything electrical, and ring 020 8194 3009.
