@bigfishac: Dead thermostat batteries could be the reason your AC shuts off during a heatwave and most people never see it coming. 🔋 Swap them out before summer hits full force. It takes 30 seconds and could save you a miserable night sweating it out while you wait on a tech. Got other summer maintenance questions? Drop them in the comments & we'll break it down for you. 📞 409-210-7500 | www.bigfishac.com
