No public data found supporting either the sales drop or the election-fears causation.

The claim in context
Alex Borg has argued that the sale of air-conditioning units in Malta has fallen because consumers are anxious about a possible early election. The claim is striking because it ties a discretionary household-goods purchase to political-cycle anxiety — a non-trivial economic argument.
What we'd need to verify it
Two distinct things would have to hold for this claim to check out: (a) Maltese A/C unit sales fell in a measurable, statistically significant way, and (b) the cause was election anxiety rather than weather, financing conditions, replacement-cycle dynamics, or any of the other factors that drive durable-goods purchases.
On point (a), a search across NSO retail-trade data, importer reports and industry trade press did not surface evidence of a drop. NSO's monthly retail-trade releases do not break out A/C units specifically, so the claim would have to be based on importer-association data or a private survey.
On point (b), causation is the harder problem. Even if sales did fall, attributing it specifically to election fears requires either a survey of buyers asking why they deferred, or a counterfactual that isolates election sentiment from other variables. Neither is publicly available.
Bottom line
Without a sourced sales figure and a credible causal mechanism, the claim cannot be verified. We mark it Unproven and will revisit if importer data or a Borg source is provided.
