Case Study

Downtown restaurant RTU failure

A Tucson restaurant on 4th Avenue lost cooling an hour before dinner service when its rooftop unit fan motor seized. Crest Air dispatched within 90 minutes, swapped the motor, and recalibrated airflow so tables stayed seated and the kitchen never shut down. Result: zero revenue loss and a preventive maintenance plan scheduled for the off day.

Case Study

Midtown office hot-floor complaints

A three-story office near Broadway experienced rising temperatures after an aging VFD kept tripping. We delivered a same-day repair, cleaned contactors, and staged a retrofit plan so the property manager could brief corporate on a permanent solution. Result: employees stayed onsite and the replacement budget was approved without emergency rent credits.

Case Study

Warehouse inventory at risk

A logistics warehouse off I-10 saw interior temps spike above 90°F when a packaged unit coil failed during a weekend shift. Crest Air provided temporary spot cooling, sourced the coil first thing Monday, and had the RTU back online before heat damaged stored goods. Result: shipping commitments stayed on schedule and the facility avoided spoilage claims.

Industries we support

Restaurants, offices, retail, and warehouses run on uptime

Downtime equals lost revenue and unhappy occupants—especially when rooftop units (RTUs) serve entire dining rooms, open office floors, shopping aisles, or storage bays. Crest Air keeps dispatch, diagnostics, and approvals tight so you can reopen, seat guests, or resume production without guessing.

Rooftop unit (RTU) expertise

Most Tucson commercial sites rely on RTUs to condition entire suites. We service, replace, and stage lifts for multi-ton equipment, coordinate crane days, and protect roofing systems while the cabinet is open. Whether you operate a restaurant on Campbell Avenue or a warehouse off I-10, we plan around your business hours so RTU downtime doesn’t eat into revenue.
