Planned maintenance versus reactive repairs: which actually costs less?

The four hidden costs of running reactively

• Downtime: an office at 28C sends people home; a failed cold room stops a kitchen trading
• Stock loss: a single refrigeration failure can write off more value than years of servicing
• Energy waste: fouled coils and low charge raise running cost every single day before failure
• Shortened equipment life: compressors that run hot and long fail years earlier than they should

What planned maintenance actually prevents

Most breakdowns we attend are not sudden. They are the end point of something that was visible months earlier: a condenser slowly furring up, a defrost fault gradually icing an evaporator, a refrigerant leak losing charge a little at a time, a condensate drain silting until it overflows.

A planned visit catches those while they are cheap. The difference between clearing a drain and replacing a water-damaged ceiling is entirely a matter of timing.

When reactive is defensible

If you have one wall split in a spare office that would not stop the business if it failed, reactive is a reasonable choice. The argument for a contract gets stronger the moment the equipment is load bearing for trading, holds stock, cools a comms room, or sits under a warranty that requires servicing evidence.

Getting the comparison right

Compare like with like. A contract price covers scheduled labour, consumables, reporting and priority response, and typically discounts parts and additional labour. A reactive budget must include emergency call out rates, the cost of waiting for a slot in peak season, and the value of whatever stops working in the meantime.
