Common causes
A refrigerant leak can develop at connections, refrigerant lines, valves or coils in a mini-split system. Possible signs may include reduced cooling performance, unusually long operation, ice formation or oily residue near a connection. These symptoms can also have other causes, so a refrigerant leak should be confirmed through professional diagnosis.
When to request service
If you suspect a refrigerant leak, request professional service to locate the cause and determine the appropriate repair. Adding refrigerant without repairing a leak does not correct the underlying problem. Do not open the refrigerant circuit, handle service valves or attempt to recharge refrigerant yourself.
How much can this repair cost?
Basic air conditioning repairs or initial work typically range from $650–$1,200 MXN. Repairs requiring parts or more extensive work can range from $1,200–$5,500+ MXN.
The final cost depends on the cause of the problem, diagnosis, labor, required parts and materials. Replacement parts are quoted separately when applicable.

Frequently asked questions
How do I know if my mini-split has a refrigerant leak?
Possible signs include reduced cooling performance, unusually long operation, ice formation or oily residue near a connection. These symptoms can also have other causes, so professional diagnosis is needed to confirm a refrigerant leak.
Why can a mini-split lose refrigerant?
A leak can develop at connections, refrigerant lines, valves or coils in the system. The exact location should be identified before the appropriate repair is performed.
Can a refrigerant leak be fixed by simply adding refrigerant?
No. Adding refrigerant without locating and repairing the leak does not correct the underlying problem. The system should be inspected to determine where the leak is and what repair is needed.
When should I request repair for a possible refrigerant leak?
Request professional service if the mini-split loses cooling capacity, runs for unusually long periods, develops ice or shows other signs of a possible leak. Do not open the refrigerant circuit or attempt to recharge refrigerant yourself.
