Refrigerant Charging by Weight
Every vehicle has a manufacturer-specified refrigerant charge weight, typically stamped on an A/C label under the hood. Under-charging reduces cooling performance; over-charging causes high-side pressure spikes that shorten compressor life. The only correct method is charging by weight — not by pressure, sight glass, or feel.
Refrigerant Charging by Weight
Why weight matters
Refrigerant pressure changes with ambient temperature. A system that reads "full" on a cool morning may look "low" on a 35°C afternoon — without any actual change in refrigerant quantity. Charging by weight to the manufacturer-specified gram amount removes that variable entirely — you get the exact charge the system was designed for.
Manufacturer-specified charge
We look up the OEM charge specification for your vehicle before loading any refrigerant. That weight — typically expressed in grams — is loaded to within a few grams. No guessing, no estimating by feel.
R134a and R1234yf
We carry both R134a and R1234yf refrigerants. They are not interchangeable — the fittings are physically different, the charge specifications differ, and mixing them is illegal under Canadian environmental regulations. We verify which refrigerant your vehicle requires before service.
