How do I check my refrigerant level?

Checking refrigerant levels requires specialized equipment and should only be done by a licensed HVAC technician. Refrigerant systems are sealed and pressurized, making this a job for professionals with proper gauges and certification.

Signs your system may be low on refrigerant include reduced cooling performance, ice buildup on the evaporator coil, hissing sounds near the outdoor unit, or higher than normal energy bills. However, these symptoms can also indicate other issues like dirty filters, blocked airflow, or mechanical problems. Low refrigerant typically means there's a leak somewhere in the system, since refrigerant doesn't get "used up" during normal operation.

In Ottawa's climate, refrigerant issues are particularly noticeable during our hot summer months when your AC system works hardest. The most common refrigerant types in residential systems are R-410A (in newer systems) and R-22 (in older systems being phased out). Each requires specific handling procedures and environmental regulations must be followed during any refrigerant work.

Safety is critical when dealing with refrigerant systems. Refrigerant can cause frostbite if it contacts skin, and improper handling can damage your system or create environmental hazards. Additionally, adding refrigerant without fixing the underlying leak is wasteful and won't solve the problem long-term.

What you can check yourself is whether your air filter is clean, vents are unobstructed, and the outdoor unit has clear airflow around it. If you suspect refrigerant issues, turn off your system and contact a licensed technician who can properly diagnose the problem with manifold gauges and determine if refrigerant service is needed.
