Q&A
Why is my AC in Killeen turning on and off every few minutes (short cycling), and how can you fix it?
Short cycling is a common issue here, often caused by an oversized unit, a dirty air filter restricting airflow, or a refrigerant leak. It wastes energy and wears out your system. Our technicians perform a thorough diagnostic to pinpoint the exact cause—whether it's cleaning coils, sealing duct leaks, recharging refrigerant, or checking electrical components—to get your system running in longer, more efficient cycles.
My Killeen home's thermostat seems to have a mind of its own with incorrect readings. Is this a wiring problem?
Absolutely. Faulty or aged thermostat wiring is a frequent culprit for erratic temperature control in our area. Loose connections, corrosion, or incorrect wiring can send wrong signals to your HVAC system. We'll carefully inspect your wiring, ensure it meets current standards, and properly install or replace your thermostat to restore accurate communication and consistent comfort throughout your home.
