How do I know if my AC has a refrigerant leak?

Refrigerant leaks typically show up as reduced cooling performance, ice formation on your AC unit, or hissing sounds from the outdoor condenser. These leaks not only hurt your comfort but can also damage your compressor if left unaddressed.

The most obvious sign is poor cooling performance - your AC runs constantly but struggles to reach the set temperature, especially on hot Ottawa summer days. You might notice certain rooms staying warm while others cool normally, or your system taking much longer than usual to cool your home.

Ice buildup on the indoor evaporator coil or outdoor unit is another telltale sign. When refrigerant levels drop, the remaining refrigerant gets too cold and can freeze moisture in the air. You might also hear hissing or bubbling sounds from the outdoor condenser unit, which indicates refrigerant escaping through a crack or loose connection.

Higher than normal energy bills often accompany refrigerant leaks because your system works harder to achieve the same cooling. In Ottawa's climate, a properly charged AC system should efficiently handle our summer temperatures without constantly running.

Never attempt to add refrigerant yourself - this requires specialized equipment and certification. Refrigerant is an environmental hazard that must be handled by licensed technicians. More importantly, simply adding refrigerant without finding and fixing the leak will only provide temporary relief.

If you suspect a refrigerant leak, turn off your AC system to prevent compressor damage and contact a licensed HVAC technician immediately. We can locate the leak using electronic detectors, repair it properly, and recharge your system to manufacturer specifications.
