When most people hear the words "air conditioning problems", it sends a shiver up their spine. That is because the air conditioning system is fairly complex. It has a lot of parts and when it is broken, it is expensive to repair. 

The most common cause of air conditioning failure is leaks. When the Freon or refrigerant, the stuff that makes the air cold, leaks out, it reduces the efficiency of the system, making the compressor work harder to cool the air. Then there is the all-important oil that lubricates and keeps the compressor from failing which is carried by the refrigerant. So you can see how important it is to keep your A/C properly filled with refrigerant to move the oil that protects the compressor. 

Can I Use Stop Leak to Fix My A/C? 

When the cold air your vehicle puts out starts dwindling, you may be tempted to "try" a cheap, quick-fix like a leak sealing product. Sometimes this works-for a while. Sometimes it does not. I will explain... 

Problem #1: There are two types of sealants available. And they each work differently. So for starters you will need to identify exactly the type of leak you have, and then purchase the right sealant for the job. Then you would probably stand a chance of stopping or slowing down the leak. However, more often it will end up costing you more money later on. 

Problem #2: We have encountered systems with un-repairable restrictions and damaged compressors due to these sealants. Some systems sustained damage within a week of use! 

The good news-these stop leak products are fairly inexpensive. 

The bad news-most vehicles with sealant installed will require replacement of all the A/C components to do the job right with a warranty. This is because there is not an approved flushing solvent (at this time) that will remove hardened sealant. And A/C compressor builders and suppliers are scrutinizing returned compressors and may not warranty one if there is sealer in it, just as they have refused when they find evidence of unapproved refrigerants, oils, or flush chemicals present. 

Most auto repair shops will not use their expensive A/C machines to recover and recharge your A/C if your system tests positive for an A/C sealant. They are reluctant to service a system with sealant because their machine WILL be damaged by these materials. So if you cannot afford to replace all of the refrigerant carrying parts in your A/C system, then we do not recommend using any sealant products. 

What things can I do to prevent an air conditioning breakdown?

First you should run the air conditioner regularly, even during the winter, so that it lubricates itself and keeps the seals from drying out, which leads to leaks. Your owner's manual will have recommendations for how often to operate your air conditioner. Of course, if it is not working right, now is the time to get it checked. 

Then have your air conditioning system serviced every other year to help it keep its cool. A quick inspection and sometimes adding a little refrigerant can help you avoid having to bring your air conditioner in for major repairs. It will pay for itself in the long run. So, if your A/C is just a lot of hot air, bring it to us for an inspection. 

If you continue to use an improperly running air conditioning system, it can - and usually does - end up being a bigger expense than if you get it fixed early. We'll be happy to check your system out to see if you simply need more coolant (Freon) or if there is bigger trouble brewing. And don't worry, if we check it out and find nothing is wrong, we'll tell you that too.
