TJ Services | Experienced HVAC Repair in Ashburn, VA

Short cycling is a common issue in our area, often caused by an oversized unit, a dirty air filter, low refrigerant, or a faulty thermostat. It strains your system and increases bills. At TJ Services, our technicians perform a comprehensive diagnostic to pinpoint the exact cause—whether it's a simple filter change or a more complex refrigerant issue—and provide a lasting fix to restore normal, efficient operation.

Signs of leaky ducts include uneven heating/cooling between rooms, higher-than-normal energy bills, and excessive dust. We use specialized tools, like duct blasters and smoke pencils, to detect leaks in your ductwork. Our fix involves professionally sealing the leaks with mastic sealant or metal-backed tape, which is far more effective and durable than standard duct tape. This ensures your conditioned air stays in the ducts and reaches your living spaces, improving comfort and efficiency.

Our preventive maintenance visit is designed to catch small issues before they become big problems. We thoroughly clean coils and components, check refrigerant levels, inspect electrical connections, test safety controls, and calibrate your thermostat. For Ashburn homes, we pay special attention to factors that cause short cycling and duct efficiency. This service helps extend your system's lifespan, maintain manufacturer warranties, and improve overall energy efficiency, saving you money in the long run.
