Suppliers for HVAC parts?

[Innovate1]

I need a pressure sensor for a furnace. Any suggestions for good places on line? I figure probably better prices than my local dealer that may not want to sell them to me without labor to put them in. Any suggestions? I am looking at hvasupply.com that has what I need. Anyone used them? I could buy them though a local supply that has some HVAC stuff but would have to cross them to something more generic and not sure I want to go through the trouble and risk something not being the same.

What brand of furnace?

I would try Johnstone Supply, but I have not worked on a furnace for years.

Johnstone will only sell to contractors in Nebraska and most of iowa.

when I rebuilt my furnace this past winter, I got most everything on amazon...heat exchanger came from a local place, but the pressure sensors, exhaust fan, computer board, igniter, and gas valve all came from amazon.

they don't take returns, but they are good on price and quick ship. I literally have a brand new furnace for $600 in parts...

otherwise, appliancepartspros.com but they aren't as cheap.

our local servicemaster was my old go-to but they shut down just prior to the covid...

I have a connection to buy from Johnstone but they don't have the same brand sensors and I would need to go there to see about a cross - they will barely say if they have something in stock over the phone. Trane S9V2 furnace. Could probably cross to another brand but there isn't much info on specs. The contractors get on them if they sell to homeowners and that's where they make most of their money so I get it.

Supplyhouse doesn't list the parts I need.

amazon has plenty of suppliers for parts. not sure what switch you need but for example:

https://www.amazon.com/dp/B012HEJ0PC/?tag=atomicindus08-20

Parts I need:
SWT03924 pressure switch 0.2 wc
SWT03926 pressure switch unknown pressure
SWT03992 Pressure switch 0.7 wc

Amazon doesn't have them that I could find. Might have an equivalent but it takes digging. And not sure if they are for positive or negative pressure and if they open or close above a certain point.

give hvacsupply a call if they have all 3 listed. use a CC you can dispute easily. and see what shows up.

Why are you replacing them? Pressure switches rarely fail unless they are mounted in a way that condensate gets into them or they were junk when new.

diaphragms get dry and cracked and no longer work or work properly. I've replaced mine multiple times as they age.

S9V2 is a newer model, it should have a 10 year parts warranty... Pressure switches are often where venting issues show up. have you confirmed the venting is correct and that the switch is defective?

X2. I can't count how many I've replaced in the last 35 years.
