Ac not cooling
I have a 2007 and have taken it to several mechanics and no one can determine the Freon leak. It will hold for a few weeks and then stop blowing cold. Any ideas?

I chased the exact problem for two seasons on our 09 RX .. The evaporator coil had a very slow leak…. Did the correction myself… not an easy job but VERY rewarding! Only symptom was an odor from dash vents on start up..

I'd take it to a shop that has certified a/c tech. They'd put some dye in the system & put a vacccum on it to start with. I'd change out the orifice tube....

I have one of the Refrigerant Leak Detectors from Harnor Freight.
I've used these types of detectors for many years, works excellent and this one costs $70.
>> sniffs for leaks and beeps get louder and faster as you locate the source, kinda like a treasure finder. lol

May charge a "restocking fee of 10%-20%" if they wanna get hard on ya but you can at least try it out and return if it doesn't work(and keep it if it does.
PS- if it takes less than a month for the freon to leak out, you have a good leak.
PS- I've never had a leak I couldn't detect with one of these- I could do it in 5 mins if you were here. lol
I've never used a sealer but I hear people do use it.
