It’s been a long, hot summer in Arizona, and your air conditioner has been working its hardest to keep your home cool. Much to your surprise, a check of the system revealed that your unit was low on refrigerant — but how can that be? Even though the refrigerant system in your air conditioner is closed, and it recycles the same refrigerant over and over again, sometimes leaks can appear due to rubbing or wear, allowing your refrigerant to slowly make its way out into the environment. Fixing this problem cost a lot less than you think, often below $100 depending on your state.
Common points for leaks to start are valves, connectors, copper lines and the evaporator coil. Sometimes, these leaks can be very hard to find, but you should never let an air conditioning contractor recharge your unit without repairing the leak first — it’s bad for the environment and will end up costing you even more as he continues to feed refrigerant into your system that will simply leak back out.
Finding a Refrigerant Leak
Tracking down a refrigerant leak can be a tricky task, one that may end up costing you much more than the unit is worth. However, if your air conditioner is still relatively young and hasn’t given you other major problems, you want to have it repaired instead of replacing it. In this case, your air conditioner technician will do his best to hunt your leak down and repair it. Here are some of the ways we locate refrigerant leaks:
Electronic Sniffers. A leak in an easy-to-access area is quickly found using an electronic sniffer, a device built to detect high concentrations of refrigerant in the air. It’s not the most precise method, but if the suspected area around the leak can be visualized, it will usually get your contractor close enough to locate a suspect valve or notice a small hole in the tubing.
Bubbling. It’s not exactly high-tech, but bubbling is a great way to find those big, harder-to-detect leaks without breaking out the more expensive equipment. After introducing some inert gas to your air conditioner, we paint the suspected area with soapy water. Soon, the inert gas starts escaping and blowing bubbles. From there we just have to rinse the soap off and fix the problem.
Ultraviolet Inspection. Especially tricky leaks may require an ultraviolet inspection process. A technician will insert a liquid tracer into your system and allow it to circulate along with your refrigerant. After about two weeks of air conditioning use, a tech will return and carefully scan your entire system with an ultraviolet light, looking for signs of the tracer. Very small and intermittent leaks are much easier to uncover using this method.
Once the leak is properly tracked, your air conditioner technician will be able to perform the right repair to your system, ensuring that the leak is completely stopped. Most of the time, it’s a matter of a valve replacement or soldering a small section of copper tubing, but if the leak has appeared in a very thin or corroded portion of your system, it may be difficult or impossible to guarantee a satisfactory repair. This is when you’ll have to decide if it’s time to give up on your old system.
A few signs that your old air conditioner should be replaced, rather than attempting a repair, include:

I wanted to make sure my air conditioner was ready for summer. Fernando came out and made sure my unit was tip top. He was friendly, professional and not a sales man. Thanks Fernando!

We woke up in the middle of the nite on memorial day to a hot house. I called precision at 6am and they were here before noon. Simple problem fixed, cool house. I love these guys!

He did a great job; professional and knowledgeable! Kalin is the technician’s name and Precision Air and Plumbing should take a bow for hiring such an invaluable employee!!!
Precision Air is a company of integrity. I signed up with them August 1st, 2019 for their AC maintenance plan for 2 years... Someone from their office called me a week ago to set up their yearly maintenance visit. SO GRATEFUL.
Precision Air and Plumbing is a wonderful company to work with! They are very experienced and professional. They have helped us in our home for many years via a/c service and air duct cleaning.
It was time to replace our AC, and so our choice was Precision Air, as we've been with them for over 20 years. Teman & Julian did an excellent job on the installation today, arriving on time.
