"AC died during a heat advisory in July with my elderly mother visiting. Called Hawana at 9pm — technician arrived within the hour. Diagnosed a failed capacitor, had the part on the truck, fixed same night. No overtime charge whatsoever. This is exactly who you want saved in your phone."
"Heat pump stopped working on a Saturday morning in February — stuck in cooling mode with -5°C outside. Hawana here in under 90 minutes. Diagnosed a defrost board issue and had us back up and running before noon. No weekend surcharge. Genuinely impressed."
"Furnace out at 11pm in January. Tech at my door in just over an hour, fixed the flame sensor that same night, no overtime charge. Heat restored before midnight. Cannot recommend Hawana enough."
