Why is my car blowing warm air?  

The most likely reason is that you are low on refrigerant. The most common culprits are the AC Compressor, blocked or broken condenser, condenser fan or the evaporator. If your system is low on freon, it almost always indicates a leak. There could be very slow permeation loss, but that would generally take 5 years or more.

Is a refrigerant leak costly to fix?

Not necessarily. Although leaks require attention, they are not always costly to fix. Some leaks are at accessible service ports, or easily accessible o-rings.

Which AC repair is the most involved?

Changing the AC evaporator typically involves removing your vehicle's entire dashboard. This can be a very significant job, with an average repair time of 15 hours depending on the vehicle.

What are the types of refrigerant and what is the difference?  

There are currently two main types used in modern day imports R134A and 1234YF. R134A started to be phased out in 2013 and by 2017 virtually all new vehicles of European origin were fitted with 1234YF. R134A and 1234YF function similarly, 1234YF is considered to be more environmentally friendly. Rennen Imports services both refrigerants. 

Why shouldn't I use an off-the-shelf AC recharge kit from a parts store?

This may seem like a quick economical fix, however they do not address the root problem. 

The kits are very universal and it is difficult to properly gauge the amount of refrigerant introduced into the system. Additionally, almost all of these systems contain stop leak.

Import AC systems have small, intricate passages. Stop leak has been known to clog the vital components of an AC system leading to more costly repairs down the line.
