E & J Heating & Cooling - Antioch's Professional HVAC Repair

Common signs include uneven heating or cooling between rooms, unusually high energy bills, and excessive dust. You might also hear whistling or rattling from the ducts. Our technicians perform a thorough inspection and can conduct specialized tests to pinpoint leakage areas, ensuring your system isn't wasting conditioned air.

Refrigerant leaks are often caused by corrosion, vibration, or factory defects in the copper lines or coils. This is a serious issue because low refrigerant makes your AC work harder, leading to poor cooling, frozen coils, and potential compressor failure. We locate the leak, repair it, and recharge the system to the manufacturer's exact specifications for optimal performance.

Absolutely. Our comprehensive diagnostic approach allows us to assess your entire HVAC system. We can identify and address multiple issues, such as sealing leaky ducts to improve airflow and repairing refrigerant lines to restore cooling power, all in one efficient visit to minimize disruption to your Antioch home.
