View Full Version : Need really good A/C shop - GTA

I want to do a conversion from r12 to r134a and I would like it to be done right. So, I am looking for an A/C specialist in the Toronto area. Not just a wrench who happens to own some A/C equipment but a real specialist who can do this stuff in their sleep. Any suggestions?

I'm in the process of having mine converted at a father and son place on sheppard and midland across from cycle world called arsen's - nice guys - all my r12 had leaked out. for @$125 they changed the nipples and filled the system to find the leak - it was blowin cold but the drained the 134 cause of the leak - they let me order my own parts - no mark up! i had to order a new fan resistor, receiver dryer and pressure switch - $499 at the dealer $139 USD shipped from bav auto parts should be in any day then i'll go back for install and refill with 134

they also did my dad's 85 buick - needed at new condensor which he sourced and they installed -he's happy - frosty in there now

Did you need a new compressor for the Bimmer? According to Koalasports, my 325ix is not compatible with r134a. However, when I call some of the BMW specialists, they all tell me not to worry about it. I don't trust them. I just think they want the conversion business and don't want to turn me off with a high quote for a new compressor.

Let me know how the cooling is with the r134a. I converted an old Alfa a few years ago and the A/C worked like crap afterwards. So bad that I sold the car. In this particular car, the heat would pour out of the transmission tunnel through the shifter boot. Without A/C, it was undriveable in the summer. I don't want the same situation in the BMW.

no new compressor is required (so far!!) last summer I had freezing cold a/c - my problem was the leak from the receiver-dryer/pressure switch (look straight down behind passanger headlight for what looks like an intersection of a/c pipe). when they charged the system with 134 there was a "blockage" which didn't allow the proper pressure/amount? of 134 to be put in. he backed it off a little and it blew cool air - strong enough that I could feel the temp change outside the car by the open window - he put dye in and sure enough it puddled just in front of the rt frnt tire - the mech removed the 134 and told me to buy the pressure switch and receiver dryer (fan switch was a different problem but also on the a/c) and come back to have them installed. he suspects that the blockage is related to the faulty receiver dryer

one other thing - check out the tech section on bavauto.com for a short "how to" on conversion. it talks about the receiver dryer and pressure switch but makes no mention of a need for a new compressor

the guys doing my work are not "bmw specialists" but the mech wasn't just guessing - he looked up my system specs on a cdrom before getting to work - they're pretty honest guys (saved a ton of $$ on a brake job on my suv vs the dealer) I think (hope??) if a new compressor was required for the conversion that they'd have told me - now you've got me wondering:confused:

Okay, your guy sounds like someone I could work with. Do you have a phone number or are they easy to find?

had the new receiver dryer, pressure switch and fan resistor installed today and r134 added - It works great - I don't notice a difference from when it was working with r12 last summer

Excellent. I get my parts next week and will do the conversion just in time for summer to be over!
