I heard from my supply house that there are no more 370 only 440 any truth?

 

I'm not sure about that, but many capacitors now will show a dual rating 370/440 volt.

Why they do that, I don't know. I'm guessing it is easier than trying to explain that a 440 volt cap will work fine where a 370 volt one was previously installed.

 

I may be brainwashed now! But whenever I see the word Nest the first thing I think of is POO!

As far as nest , I never sell them. I installed a dozen or so for clients. Recently, dwp had an ac optimization program through a company w a contract. Some cat came to my pad and installed two nests on both of my brand new American standard’s I installed a few years apart. I honestly like nest from a consumers point of view. If I’m lazy and I don’t want to get out of bed to turn my ac on or heat in the middle of the night.

However, from a tech side, I had a few run ins with them and I never had issues of them stealing power that goes to the contact relay.

They just throw an error code when your contact relay’s windings are burned.

Product is relatively expensive, but I got two for free and I’m planning to keep them.

Previously, I used a simple Honeywell 3000 which I sell to clients that want a simple non programmable option.

 

I use the 440v one. I have a plastic box full of them. I have an account w Cali home builders. Hundreds of HPs. Mostly take 35x5s. Their previous guys used supco’s.

What trips me out is when I open extremely old resi units, I find the enormous caps that are operational from the 70s

 

I believe those older caps use PCBs.. I could be wrong. I'm sure someone will correct me if I am.

 

We use GenTeq, AmRad, and TradePro.

The GenTeq are the ones that I see the most failures with, but they all last longer than a year.

 

I installed one for my wife's brother on a payne unit last June. This month it took a dump, so I just installed another one and went on my merry way because I was late for something. I didnt check amp draws.

You should check the voltage the capacitor is exposed to while the unit is running. It is much higher than line voltage.

Are you using 370 or 440 volt capacitors?

Many units will operate at a voltage greater than the 370 volt rating of the capacitor. This will reduce the life of the capacitor, and the reason to only use 440 volt rated capacitors.

 

you think that's bad? try promoting Nest... or IceCOLD...

 

I just looked up icecold. First time I've heard of it. People will buy anything huh lol.

 

Titan HD mainly, they are made in US. Sometimes the turbo mini, 200 or 200X. Haven't had many issues that I'm aware of.
