I won't miss those Bryant compressors one bit.....

With that said though, be careful because there is some junk out there.

I had a Rheem unit this spring with a bad heat exchanger. Horizontal unit in a crawlspace with a right hand supply and exhaust coming out of the left. Called to get a replacement xchanger and they no longer make the furnace or xchanger, even though it was in the warranty period of 20 years. How can they legally do that? So instead of getting a heat exchanger they gave them $275 toward a new RHEEM unit of their choice. I don't think that is right. If it is under warranty then the parts should be available.

I know which supply house chain you refer too. I used to go in and pick up compressors 3 or 4 at a time for home warranty company work (ahs) while guys like you got stuck waiting. Sorry John. I agree its not right. People that deal in the equipment that a supply house sells SHOULD get priority over someone like me.

Amen, brother !!

My local Heil distributor is also a "stocking Copeland distributor"....I've witnessed multiple occasions, where a "dealer" had a bad compressor in warranty, and they had the compressor in stock...but they wouldn't let the dealer have it, because it wasn't "ICP warranty stock".

Oh sure, they'll SELL it to you, but you still have to wait a week for the warranty compressor to come from ICP...and then you'll have one of your very own in stock....at your shop, on your dime.....unless you want to make your warranty customer wait a week....and you know where that will get YOU

I have been told that Goodman puts better parts in the Amana line and uses a different circuit board with more bells and whistles. No one around my area sells amana due to a cocky distributor years ago.

Payne is the old Carrier design.

Personally, I like selling companies that find something that works and sticks with it. I like to sell equipment that has parts that any hvac company can get and will likely have in their truck. I do not like where the hvac industry is heading with special parts on equipment. I am tired of waiting a week to get a part for Trane and Carrier. Twice I have been told that txvs are 2 months out at Carrier. That is absolute bull crap. If you have something under warranty you should have the parts.
I have heard several complaints about Tranes new airhandlers, which is a disappointment because they had a good design for so many years.
Just my opinion.

That last statement makes me look like a hero about 3 times a month during the summer. A dremel tool and low heat will fix coil leaks at the tube sheet. If the customer don't ahve the replace I will repair all day long. And I have yet to be called back on a repair like this, knock on wood.

Now Formicary leaks are a different story. I am talking about stress crack type leaks. Formicary leaks that bubble little cacunes down the coil have no help.

On the aluminum coils, there are kits to repair those and some products with low melt points out more and more.

Just a quick explanation about copper AC evap coils (indoor coils):

When two different metals are in contact, and it is wet... a process called 'dissimilar metal corrosion' happens. The water causes the two metals to become a battery, the minute elec current causes the metals to deteriorate. In my experience, it is not the contact between the CO and AL... it is the contact between the CO and steel end plates. And yeah, that area is difficult to repair. Done it... however difficult. Better to either replace the coil or replace the system.

BAHH! Sitting here with a grin on my face! Thanks!

(I'm realizing that more and more I'm trolling for laughs)

true.

If you poke a hole in it, they're repairable.

If it springs a leak and you fix it, you'll be back next week fixing another leak.

Makes sense

The copper is too thin....the price we pay for "efficiency".....

Sorry about the typo. It should read be not nb. I can't edit my posts for some reason at this time.

X2. And the newer aluminum coils I've had no problems with. Its just the older ones I've had to take back. Espcially the goodman coils. The carrier coils seem to nb e made better imho.

Think about it. Where do most coils leak?

At the tube sheet.....

Modern copper resi coils aren't field repairable anyway.

Nordyne seems to have focused on old appliance brand names, that the AARP crowd easily recognizes. They may be smarter than we think.
