How often a commercial AC should be serviced in Lahore

Twice a year is the working minimum

For a commercial building, the two services that matter are the one before summer and the one after it. The pre-summer service is the one that prevents breakdowns, because it catches the weak component before the load finds it. The post-summer service clears out what a season of running has collected.

Buildings that run their air conditioning through winter as well, which includes most hospitals and many hotels, need a third visit between the two.

Some rooms need more, whatever the calendar says

A server room or a laboratory that has to hold a temperature band is not on a comfort schedule. Its cooling is part of the equipment, and the cost of drift there is the cost of whatever is inside the room. Those units get checked more often, and they are the first ones attended to when something fails.

The same applies to kitchens, laundries and any plant room where heat, grease or dust load the unit far faster than an office does.

What a service should actually include

Cleaning filters is the visible part and the smallest part. A real service checks the refrigerant charge and looks for the leak if it is low, cleans the coils rather than only the filters, checks the electrical side including contactors and connections, confirms the drainage is clear so condensate is not finding a ceiling, and records what it found.

That last point is worth insisting on. A building with a service record can see which units keep needing attention, and that is the information that tells you when replacing a unit has become cheaper than repairing it again.

Planning it around the building instead of the contractor

Taking a unit offline is disruptive, so the schedule should follow how the space is used. Teaching blocks are serviced in the term break, hotel floors when occupancy is lowest, offices outside working hours where the work would take a floor out of service.

This is the practical argument for a maintenance contract over calling each time. The visits are planned into the building calendar in advance, rather than arriving as an emergency on the day the room is fullest.

What it costs to skip

An unserviced unit does not fail quietly at a convenient moment. It fails in May, during working hours, in the room that can least afford it, and the repair then competes with every other emergency call in the city for the same week. That timing is the real cost of the service that was skipped, and it is why the pre-summer visit is the one worth protecting in a budget.
