A Quick Story: One Roof, Zero Cooling, 100% Solved

Last July, a bakery in Downtown LA called us in a panic. Their commercial rooftop HVAC unit failed the day before a big event. Customers were sweating, the bread was over-proofing, and the manager was losing it. Our crew showed up within hours, diagnosed a fried contactor and leaking coil, and performed a full rooftop unit repair that same day. Cooling was restored, pastries were saved, and the owner left us a five-star review with a muffin emoji. True story.
