G & A Heating & Cooling | St. Louis HVAC Repair for Leaks & Duct Issues

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bills. If you notice these issues, it's best to call for professional diagnosis and repair to prevent further damage and restore efficient cooling.

Leaky ducts force your HVAC system to work much harder, leading to hot or cold spots in different rooms, increased dust, higher utility costs, and uneven temperatures throughout your home. Our team performs detailed duct inspections and uses professional sealing methods to ensure conditioned air reaches every room efficiently, improving comfort and lowering energy usage.

Simply adding refrigerant is a temporary fix. EPA regulations require finding and repairing the source of the leak first. Our technicians use advanced tools to pinpoint the exact location, perform a permanent repair, and then recharge the system to the manufacturer's specifications. This corrects the problem, protects the environment, and ensures your system runs at peak efficiency.
