Common causes
A heat pump may develop some frost on the outdoor unit while operating in heating mode, and the system normally uses a defrost cycle to remove it. Excessive or persistent ice buildup may be related to restricted airflow, dirty filters, problems with the defrost cycle, obstructions around the outdoor unit or a fault that requires technical inspection.
When to request service
Check that the filters are clean and that the outdoor unit has enough space for proper airflow. Do not remove ice with objects or pour hot water over the unit. If the ice remains after a defrost cycle, quickly returns, covers a large portion of the outdoor unit or the system stops heating adequately, consider requesting a professional inspection.
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.
