You say fan, but is it actually a powered fan or a roof ventilator, driven by wind and air movement only ?

If only a passive ventilator, than an HVAC contractor or roofer should be able to handle it - likely needs lubrication, or possibly new bearings.

If a powered fan (attic fan, whole-house ventilation system fan, bathroom fan, kitchen fan) an HVAC contractor can handle it. They commonly get loaded up with lint (bathroom) or grease (kitchen) sticking to the blades and need cleaning and lubrication. After enough years, of course, the fan/motor unit needs replaceemnt due to sheer wear - most use non-replaceable bushings rather than bearings, so generally the bearings cannot be replaced - you replace the motor or the entire unit.

Generally about $100 to clean /lube. Replacement, if needed should run $150-250 for a typical household unit (about double that if a whole-house ventilation fan), assuming replaced with same size unit (no electrical or ducting modifications needed).
