Property manager finds that one bid is cheaper than the other. Across a 10 to 30 unit portfolio and a multi-year horizon, it can become the more expensive choice — just one where the expense arrives differently - as parts failures or a recurring unit failure.
The short-term choice optimizes for the lower cost of the quarterly service fee. The long-term choice optimizes for the total cost of ownership across the asset's life: service fees, multiple premature parts replacecements, and the capital expense of premature unit replacement. The cheaper bid scrimpts on minutes per single visit. Compounded across sixteen visits over four years, it is the difference between a unit reaching its rated fifteen-year life and one quietly aging at year eight.
This difference is invisible on the quarterly timeline. A property manager has no way to see which bid is protecting the asset's tenth year. Both units are running. Both service reports say “completed.” The divergence doesn't show up as a number until years later. By then, the maintenance decision is long made in the past.
There is a way to make the long-term choice visible in the short term. Besides asking “what does it cost?”, ask “what does it measure?”. A service program that logs static pressure, refrigerant charge, and amperage draw at every visit is pricing in the labor to actually assess the unit's condition, not just service it. A program that doesn't measure is pricing in less labor — which is why it's cheaper, and why it won't catch the slow-developing conditions that turn a fifteen-year asset into an eight-year one.
The more expensive bid may not be the right one. The point is that “cheaper” and “cheaper over the life of the asset” are two different claims.
FIELD NOTE
Before comparing quarterly rates, ask each vendor for a sample service report from an existing client. A report with logged numbers and a report with checked boxes are two different products being sold at two different real costs.
