R12 Freon Versus R134a Refrigerant

At MR Automotive, we frequently work with customers who own classic vehicles manufactured before 1994 that originally used R12 Freon, a refrigerant that's no longer available due to environmental regulations. While these older systems have their charm, they represent a different era in automotive cooling technology.



For these vehicles, we provide comprehensive R12-to-R134a conversion services, which goes far beyond a simple refrigerant swap. This specialized procedure requires replacing numerous seals, O-rings, and often major components like the compressor or condenser, as R134a operates at significantly higher pressures than the original R12 systems were designed to handle.


Many of our customers are surprised to learn that we typically reduce refrigerant capacity by approximately 25% during conversion to protect their vehicle's vintage components from excessive strain, which may result in slightly reduced cooling performance compared to the original specifications.


If you're driving a pre-1994 vehicle still running its original air conditioning system, we invite you to visit our shop where our experienced technicians can evaluate your specific setup and discuss the conversion process in detail—ensuring your classic ride can keep you cool for years to come while meeting modern environmental standards.

Can Used R12 Freon Okay for My Vehicle?

At MR Automotive, we participate in a sustainable approach to AC servicing through our refrigerant recycling program. Rather than disposing of recovered refrigerant, we utilize advanced purification technology to thoroughly clean and process used refrigerant, removing moisture, oils, and contaminants through our specialized recovery equipment.



The cleaned refrigerant, once properly restored to industry specifications, performs identically to new refrigerant in your vehicle's air conditioning system, ensuring optimal cooling efficiency without compromising performance.


How Long Does it Take to Complete a Refrigerant Recharge?

A standard refrigerant recharge service at our shop typically takes between 45 minutes to 1.5 hours to complete properly.

Real Stories in Thornhill, ON

"The staff at MR automotive are very professional and honest. When Bobby told me my air conditioning would be a little more expensive to fix due to the previous owner crazy gluing all of the lines together - I was happy to understand the situation instead of just being presented with a huge bill to replace everything. This isn't the type of shop where you'll be told to replace things prematurely or without proper explanation and proof - which is quite hard to find these days!"

"MR Automotive is full of people who know their stuff but it's also great for people who aren't car-savvy (like me!) I trust Bobby & David to do a great job every time, they never sell me on anything I don't need, but make sure I at least understand what's going on. Thankful to have a mechanic I know and love."
