Condenser coils have high failure/leak rate and are hard, if not impossible to repair. The small flat tubes make it susceptible to blockage. You cannot pump down system since it lacks condenser coil capacity. Micro channels do not belong in the HVAC industry for these reasons. It’s important to share the cons in this video. The cons outweigh the pros for these coils. Thanks for sharing.
I think like everything it has pros & cons. Since the channels are smaller compared to tube-fin coils, they have improved heat transfer but also more susceptible to restrictions with small contaminants.
This is not a car it's a a/c it may work great on a car radiator but sucks in a/c or hvac world, nothing but leaks only good thing is it is made of aluminum
I install 140 of these a year with very minimal issues, like maybe one a year that needs addressing. We don't have leaks. I have experienced less than 10 failures in the last 7 years of these coils leaking. If you are leaking water... nothing to do with it being microchannel, more likely a static/airflow issue. If they are clogging on you, you didn't install them properly. Good product!
Thank you for the great feedback. Would you send us an email at communications@nortek.com? We'd like to talk more about Micro-Channel and send you some swag.
"You didn't install them properly. " No I have heard that excuse from manufacturers for decades on everything from gas furnaces to heat pumps. Truth is that all manufacturers are guilty of putting products on the market before they have been perfected and they use feedback from technicians working on real installations in the field to work out all the bugs.
Stay far away from junk microchannel ac units or you will be very SORRY! Can't handle the pressure in home ac units but work great in much lower pressured systems in a vehicle.
Junk from China or any other country, where our greedy, corrupt, overpaid CEOs and execs, can put more profits in their back pockets, pensions, and health benefits packages.
The thickness of the walls need to be increased. The overall robustness of the micro channel needs to be rethought. The pressures of 410A are to much for this. No one want's to spend thousands for something that will fail in a few years. Yes there are upsides but the downsides totally cancel them.
I HAVE to fix one and heat control is extremely important. I've been practicing on a standard aluminum coil just to get use to heat control on aluminum.
I do not like them for condensers....and I'm coming around for the evaps. I was against them at first but after taking into consideration how the copper /aluminum / steel evaps are corroding....and the fact that they are now making the aluminum evap tubing much thicker... Tube aluminum👍 micro channel👎

Prove to fail technology. Worst thing to come into the HVAC industry period. Copper tube, aluminum fin coils are far durable.
Tell that to my previous three copper tube aluminum fin coils...

Designed to fail leakers. What is the warranty ? Not much. After 6 years my Nortek is leaking.

My Nordyne junk micro channel leaking @ 5 years.
@@stevee7774 Noticed that too.
At 5 years they are done.
My Coleman started leaking after 5 1/2 years just out of warranty. Now American standard gas packages have gone to microchannel indoor coils. Junk
Thanks.
We are in the European and Australian markets. What plans do you have for R32 and CO2 refrigerant gas systems and hot water heat pumps?
Junk from China or any other country, where our greedy, corrupt, overpaid CEOs and execs, can put more profits in their back pockets, pensions, and health benefits packages.
But high psi 410a 400lbs vs r22 leaker
Which pump is good for the microchannel
A pump with a five year lifespan, because that’s all microchannel lasts in the good ole USA.

Our coils have been fully tested to industry standards and can handle 410a refrigerant.
Not for long.

That's what warranties are for, IF they fail.
Ha wired I see theses more and more often
Nice video micro channel coils pretty nice
You remind me of my high school teacher
We call them MicroGarbage

Tube aluminum👍 micro channel👎
Are they making the micro channels thicker for the condensers yet? Seems only a matter of time.
Sorry, too many issues with microchannel.
Can't be fix bum deal
Scam tech
LOL this guy is going to hell
I wouldn't go that far🤣. But I will agree that these coils are trash.
