Funny you mention that. I had a tech come out after that video and because I left the connector exposed enough, he didn’t have to cut anything. Thanks for watching!!!
No, stop! The line from the condenser is full of hot liquid. This liquid expands into a gas in the evaporator coil. This phase change sucks heat out of the air, and the cold gas then moves to the condenser OUTSIDE of the house. The insulation is on the lines to keep water from condensing inside our walls and causing water damage. The insulation outside of the home doesn't do a whole lot, and you risk damaging the copper lines or the wiring trying to strip off the old stuff.
@@RonKnowsStuff Google refrigeration cycle and you'll understand the comments your going to get about why it doesn't matter about whether or not the small amount of line exposed on the outside of your house needs that insulation replaced. That is the suction line. It carries heat from the evaporator inside your house to release through the condenser on the outside. Its insulated to keep from the condensation from damaging the inside of your home. There is no benefit to wrapping it other than aesthetics. Ive seen countless videos of people claiming it saves money by wrapping it vs it being unwrapped. That simply isn't true and no actual documentation can confirm it. On the other hand knowing how the refrigeration cycle works can dispel any myths about the insulation. I have 20 plus years as a hvac tech for reference.
@@luthergrant7336 I thought the smaller line did that. The thicker line is pretty darn cold. I appreciate the education. If you work in Florida, you’re most likely slammed right now as it is freaking hot!
@@RonKnowsStuff luther is correct. The big line is the return TO the compressor, however I'm not in total agreement about exposed copper being trivial. There is a fair amount of energy expended when water vapor condenses on something cold. Look how fast ice melts in a glass outside. The energy loss is small, but it's not trivial or zero. ALL energy put into the system has to be removed by the compressor's work so you can see even a little loss will eventually add up. You don't need documentation to prove it. You can observe that water is condensing, which means energy is expended. Again, it's not much but it's not zero.
@@RonKnowsStuff The refrigerant that is "ready" to do air conditioning is a very hot liquid and it's in the small tube. This heads into your house and right before the indoor AC evaporator coil it goes through an expansion valve where the pressure is reduced and the hot liquid passes into much larger tubes. As it expands and goes from a liquid to a gas it gets VERY cold VERY fast and absorbs heat from the coil and thus your air. The now cool (but not super cold) gas is sent back outside through the large pipe. This cool gas is still cold enough that moisture would condense on it and over time that moisture could rot the building materials of your house. Hence which is why you have that pipe insulation on it.
Oh no, underground lineset...
Yep. I’m not happy with that at all!
LOL...I was half way through writing a comment asking your opinion on the misting systems when you started talking about misting systems 😂
Definitely a must in Florida. I’m going to get one and do real world testing. Thanks for watching!!
You know the tech servicing the condenser will likely peel back or cut off a bit near the condenser end to measure the temp during tune up calls

Thanks for the comment but that’s not what was explained to me. I will do more research based on your comments. Information is always appreciated!!
