@atxhvactech: Thermostat blank? It might not be broken. 👀 A clogged AC drain line can trigger the float switch, which shuts the system off to prevent water damage — and that can make your thermostat go completely blank. Before you replace the thermostat, check this first. If you’re in the Austin area and need help clearing a drain line or getting your AC back on, give us a call. 📞 737-406-8083 🌐 www.atxheatingandac.com #austintexas #austinhvac #hvactips #homeownertips #airconditionerrepair
