How we repair your air conditioning
- Diagnosis: We talk through the symptoms and read any error codes, then test the electrics, sensors, fans and refrigerant pressures to find the real cause, not just the symptom.
- Clear quote: Before any work starts, we explain what is wrong and give you a fixed price for the repair, so there are no surprises.
- Repair and test: We fix or replace the faulty part, find and seal any refrigerant leak before re-gassing, then run the system to make sure it cools properly.
Refrigerant leaks and when to replace
If your system keeps losing cooling power, a refrigerant leak is a common cause. Simply topping it up does not fix anything, so our F-Gas certified engineers find and repair the leak first. Some very old units use R22 refrigerant, which can no longer be used to top up systems, so a repair may not be possible or worthwhile. If repairing an old unit does not make sense, we will tell you honestly and quote for air conditioning installation instead.
