The 2 year replacement seems odd to me, since the system if properly installed should be a closed loop. Unless there was an excessive temperature drop, acid in the system previously, or opening of the system they should theoretically last indefinitely. The only times I replace them is when there is a large temperature differential, I open the system, or retrofitting. One commercial setting I did work on however needed acid driers replaced every 6 months because it had a few burnouts historically and the previous contractor didn't clean the system so it was a pain to repair.

Enjoy the informative videos. To round out oyur HVAC basics and systems you should do a segment about testing adjusting and balancing (or as it become more known as testing AND balancing, as the adjustment rarely seems to get done anymore. A lot of EITs, service techs and TAB tech themselves could use the information to understand the process and techniques. Also so they can understand the importance of volume dampers and where they need to place them in a duct system. Keep up the good work, Fella's!

4: 25 The filter dryer has to battle the internal pressures, as well as the atmospheric pressures, so we need a strong casing
Uh, what? Was this worded poorly? Is there something I'm not catching here?
Higher ambient/atmospheric pressures decrease the amount of internal pressure that the filter dryer's casing needs to contain.

Could you please make a video on how hard start kids work I know capacitors are used to create a phase delay therefore applying voltage on a second set of windings but wouldn't a bigger capacitor create too much delay or is it the voltage that you're storing with the capacitor that creates the extra power needed

Isnt it efficient to use better coolant almost inert as filter driers makes compressor work harder causing high energy demand, reducing lifetime of compressor due to high workload, and if it isnt replaced Fd complicates the problems more. and how come impurities like water get into a closed tube system of coolant,

I'm still an apprentice, but I have probably installed anywhere between 40 to 80 residential HVAC systems of all kinds and never knew what the filter drier was for, why it was needed, how it was constructed, etc. I appreciate you making these videos as it educates me as an installer on the systems as a whole.

So my teachers/instructors are really hammering in the notion that the filter driers most commonly contain silica gel, but not many sources I find support that. Is there any truth to what they're saying and does someone have any sources that either support or denounce their claims.

I am a new AC Serviceman hire. Ive got to say your videos are extremely helpful and make it easy to understand (and explain) the topics of my field. Boss assigned me to make explanations about the AC&R cycle and you have done a great job in helping me do so. Thanks!

Good explanation
Just one suggestion, you can include and add Expansion tank, Air separator, pressurization unit in CHW system in your list,
Also types of CHW distribution system like VPF, CPVS, etc.
Again thanks.

People when are we going to understand your ac system will last almost the entire length of your vehicle life if you change that filter every 3 yrs it's like an oil filter keeps the system good change it

As an HVAC Tech. You only replace a drier when you open the system, it leaks or rusts, and or gets clogged. Otherwise, they can last the entire life span of the unit

I just started a year long HVAC program and all of these videos have been extremely informative. Thanks for much for the stuff you make!

Great, but you only showed a single direction flow dryer and not a bi flow dryer. It has to be very different.

Greetings, a question please, what happens in the car air conditioner if the dryer filter is not installed

I thought this was the new battery of Telsa, would like to see a video about that! This is also great!
