Called another Tech. He said it's the Evaporator in the Furnace and not the Condenser. Gave a Bid of $6,000 to Replace the Condenser and Evaporator. Doesn't anyone Troubleshoot anymore!?!? Two guys here and we still don't know where the Leak is...

Thanks for this video. My system had a small leak that I suspected was in the evaporator. But adding a pound would last almost two years when it started. Now it was 7 months. I cleaned the leaves and dirt out under the condenser looking for traces of oil. Didn't find any. But after watching this video I'm going to ask service guy to check it out before looking at the evaporator. Have a tentative appointment next April to decide if we need to replace the evaporator or install a new system. Installed in 2004. Leak started in 2018. Thanks again for the valuable information.

Thank you for posting this video. I moved into a condo apartment four years ago, and the AC never worked properly. I did some research, in short, the AC is fixable. However, I had over eight technicians look at it, and they either did not diagnose the problem properly, wanted to upsell, or both. I took upon myself to learn how to fix the AC. I would happily pay to get it fixed, but that is not an option. At a minimum, I might arrange specific repairs with a technician. I do not know enough yet for an intelligent choice. Your video brought that day a little closer.

@hvac01453 4 жыл бұрын

Here’s the delema, fix or replace? .... a typical coil can be half the cost of a new unit. If it’s a leaking joint, fine... but typically where there’s one leak, there’s more. The law of diminishing returns apply. When the repair is done, what do you have? An old, inefficient, not environmentally friendly heaper, that costs more money to operate in comparison to modern energy efficient units. Then the fan motor dies.... now your costs are more than the new unit would have cost. Good Mechanics recommend replacement units because it will save money for the customer in the end. I do commercial only, and we typically make more income by repairing these older units. In the end, the customer makes the choice, after all, we work for them!

@@hvac01453 Thank you for the interest. As I said before, I could not find an honest technician in my area. They only wanted to upsell because that is where the money is for them.

I got this detector and what I can say is, it will take time to adapt to this style of alerting. The loud hissing is usually easily located leaks, you’ll know the general area, the yellow attenuation tube helps limit the reflected sound and focus the source of the leak a bit better. The smaller leaks sound more like bacon frying, a little popping sound, this is also heard in your video. I have used it to locate about 20 leaks on one unit... these were very small leaks coming thru the solder joints and verifying with Simple green as a bubble solution. Especially useful in loud factory areas.

Just a comment, I've had 2 different companies now attempt to find a major leak in my heat pump, and both failed! Almost 15 pounds of R410A leaking out within 30 days! The second guy replaced what he saw as a leaking king valve, pressurized the system and waited an hour for any leaks to appear in pressure drop, none found. First guy had filled system with nitrogen and had a nitrogen "sniffer" that found nothing. Could a tiny leak of the sort you demonstrate result in such a large and rapid refrigerant loss, yet remain undetected by these other methods? I'm pulling my hair out and considering a complete unit replacement now.

Valves are fixable Leaks around rusted area is not worth fixing BUT we could fix them but you'll never know if it will start leaking somewhere else since it's rusted. Condensers and coils are usually 5 years warranty, and if they are registered they go up to 10 years, if your still under warranty? Replace it, If not ? Same as above, rust cause are not worth fixing , just replace it and register it so you'll have 10 years warranty, but if it's dented or got hit like accidently wile mowing? Yes fix is worth it if it's a new unit like 1-8 years old. Not all the time 8 years old units are good but mostly they are good . Filter dryer , joints, valves, bad brazing areas are all easy to fix and quick.

For me, if I can get to the leak even with a bit of butchery I fix it. A lot cheaper than replacing

Depends on where the leak is, how much bhttery is required to get to it, and if it is under warranty and what shipping costs are like. 9 year old unit developing rust on coil housing of unit owner wants to keep for a few years, advise owner and suggest coil be replaced. Leak on newer unit that is easy to get to with removing metal fins or not many fins, advise the owner and suggest fix.
