Yes, that's a classic sign of a clogged condensate drain, a very common issue in our humid Gastonia climate. When the drain line backs up, it can trigger a safety switch that shuts down your system to prevent water damage. 911 Heating & Air specialists will safely clear the blockage, flush the line, and can provide routine maintenance to help prevent future clogs and system interruptions.

We recommend biannual maintenance, ideally in spring and fall. Our Gastonia-focused service includes checking and calibrating thermostats, inspecting and cleaning condensate drain lines and pans, and ensuring all system components are functioning efficiently. This proactive care helps prevent the most frequent local issues, extends your system's life, and maintains your home's comfort and air quality.
