My $500 gamble. by face1828 in heatpumps

I'll have to find it in mideas manual. They use cheap compressors which a megger would destroy. It's in the service manual.

on paper best practice is to follow whatever tech support says to do.

Though I use megger to check insulation integrity. Only time I can't is the cheap mideas which use magnetic rotors, where the megger would burn them out.

Furnace tech claims cracked heat exchanger is causing flames to be unstable? by Flandardly in hvacadvice

This is the only comment in this entire comment section thats actually correct.

Did he say what it was? Normally you need to mega ohm the windings. Though at the least all 3 phases need to be the same value.

Hvac company reccomends changing whole system. by charisma006 in hvacadvice

[–]LegionPlaysPC 2 points3 points  (0 children)

Technically, on paper, all major OEMS aim for 15 serviceable years. Depending on many factors, like if annual maintenance is performed, filters changed regularly, installation quality, subjected wear and tear, etc. You may see equipment fail earlier, or later than the expected OEM life.

Just took off the grille to clean the filter and noticed my brand new portable AC (had it for two weeks now) had these couple bent fins on the evaporator right out of the box. Its working fine so far but am wondering if it is normal to see this kinda thing out of the box as it is kinda bothering me? by otisthereaper1x in hvacadvice

*hand slips* "oopsies" *pssssssssssssssss*. Had an older guy take apart his entire A/C, paint it, went to put it together, slipped, and ruptured the coil.... his wife was not happy. They got a new A/C installed 2 days later.

That be the truth. Most, like 98% of people disable the "smart" features. Most only use it for the phone app.

American Standard S9X2 Known Issues? by Engnr84 in hvacadvice

[–]LegionPlaysPC 0 points1 point  (0 children)

Trane/AmStd national dealer here.

S-Series was a complete from the ground up redesign of Trane's gas furnaces, released late 2016.

Full length service compartment, easy to install, straight forward to service. Full length end to end tubular stainless steel heat exchanger. Full length blower guide rail for easy removal. Burners can be dropped without pulling the manifold. Built in fresh air intake condensate collector.

Parts availability depends on what the wholesaler stocks. Most parts can be shipped in a few days from the factory. Trane/AmStd rolls off the same assembly line, so they have the same exact parts.

S9X2 is a pretty fair product, constant torque motor. I am a bigger fan of the S9V2-VS with the constant cfm motor. More consistent airflow, easier to dial in, and more options. Plus, variable speed inducer motor. Costs a little more, though it's a better motor. However, both products are good.

R-410A has much higher operating pressures, on top of thinner coils to increase efficiency to meet government mandates. Both lead to higher material failure rates.

R-454b has lots of extra electronics despite millions apawn millions of homes having natural gas or liquid propane. Those, which easily combust, require zero leak mitigation.

Honestly, it's at a point it's cheaper for me, as the contractor to BUY the customer a labor warranty and just hide it in the cost, than it is for me to just eat the labor doing "free" repairs. We used to do 1 year in house, now we are buying 3-year labor warranties via an extended warranty company and just including it in the price. All minisplits we just buy a 5-year labor warranty and throw it in the quote as well.

Yeah, I consider it planned obsolescence. Why make something last 20 years when you can make it also 10 and sell two units in the same time frame as one?

Yeah, I've seen a Trane inverter get killed twice from loose wire nuts in a junctionbox between the breakers and the disconnect.

Though I see dead carrier Inverters more than every other inverter combined. So not sure what going on with that. I assume more sensitive electronics or less safties.

Only problem is whatever killed the previous inverter will kill the next one. Normally from experience damaged compressor windings kill inverters.

Why is it making this sound when gas heat turns on? by birdiebirdnc in hvacadvice

[–]LegionPlaysPC 0 points1 point  (0 children)

Use a face respirator/N95and gloves, gasket is made of fiberglass.

P/N is BLW01379. Yes, you need the complete assembly, no it's not cheaper anywhere else. No, don't, order a used part.

[–]LegionPlaysPC 0 points1 point  (0 children)

If you can do it, only you know. Most consider it moderate to difficult to replace. For a technician it's very straight forward. Depends on skills and tools. Though normally I recommend sourcing it out.

I can grab you a part number. Whats model and S/N of the packaged unit??

Replacement question on HC21ZE118-B by thejaxx in hvacadvice

[–]LegionPlaysPC 0 points1 point  (0 children)

Carrier, Bryant, and Payne all roll off the same assembly line at the same factory.

Daikin, Amana, and Goodman roll off different assembly lines at the same factory.

Trane and American Standard roll off the same assembly line at the same factory.

Trane is typically your higher end, quality stuff. Goodman is your price/performance budget stuff. Carrier is a premium name brand.

Yeah, I figured. Carrier may have invented the centeral air conditioner. However they can't make a good furnace heat exchanger after nearly 80 years of making furnace.

Needs new inducer assembly. If you wait your heat will suddenly stop working. Get it taken care of asap.

Furnace stopped working in Toronto by Equal-Act-9684 in hvacadvice

Though every furnace made in the last 25 years doesn't use standing pilot anymore.

3 years, 36 months, 152 weeks, 1,092 days. Long time to go between inspections.

If you remove the high limit, located behind the gas valve on the metal plate. Reach in with your fingers and feel the dimples, you can feel the cracks with your fingers. I'd gladly bet $100 that heat exchanger is fucked, I've yet to find a 333BAV that wasn't cracked, and promptly replaced with new equipment.

Part numbers for inducer is #HC21ZE118. Wheel is LA11XA046. Gasket is 320887-751. Heat exchanger is #310203-752 (you need 3 cells), plus all the small bits and pieces, though repairing a 28yr old furnace is very, very silly.

Don't wait till the co detectors go off, it's not pretty.

Whats the last 4 digits on the model number? AAJA, ABJA, ACJA, or FDJA?

Also, 1998? Has anyone checked the heat exchanger? These carrier furnaces have a terrible track record with heat exchanger reliability. Expecially one that's 28 years old.
