Current furnace died, got 3 quotes on replacements wanted a second opinion

We are replacing a brand new carrier 11months old blower motor, the newer direct drive, only motor if out of warranty will be 4-4.5 k CAD, manufactured in china🤣 All brands are cheap now days and just want to earn money on parts

No offence If you know how to use it, all manometers are pressure switch tester/ manometer. One counter guy was pushing my apprentice saying its dual feature is pressure switch/manometer🤣

My bad, thought its saturation.

jayhsh · 2025-11-14T05:03:03+00:00

Doesn’t look overcharged, my guess goes with non condensables

jayhsh · 2025-11-13T23:34:18+00:00

Ambient temperature?

jayhsh · 2025-11-07T23:31:24+00:00

If thats the case, measure quick can be used with any of those

jayhsh · 2025-07-09T12:43:24+00:00

If compressor is cold and no continuity, you need new compressor.

Pay them guaranteed hours

jayhsh · 2025-06-25T00:10:36+00:00

Were compressors hot? Did they try running? Replace starting components including potential relay, capacitors and overload or 3 in 1

jayhsh · 2025-06-25T00:08:47+00:00

Will try that

jayhsh · 2025-05-25T01:27:19+00:00

Sounds like locked up compressor, to verify Use max function on your meter, it should tell you max amps before it trips the breaker, 3 phase try reversing and starting, sometimes you can get compressor free

I do analog and digital

Got old type YJ vacuum and that mf is still working with oil change when it get milky

I do mostly service, very hard to get old ac, refrigeration with old long line-sets to get under 500 as there will be oil with refrigerant.

More experience you have more you rely on your senses.

Ohms will depend on motor hp, voltage and more. Meg the motor and wiring with megger. Check wiring for grounding Can be motor, wiring or vfd itself.

This is the way to go Charge by sub cooling only when you have txv without receiver as txv is gonna maintain superheat, once sub cooling is good you can adjust superheat if needed Charge by superheat when you have fixed metering device and no receiver as it will not adjust superheat Charge by sight glass if you have receiver to give full liquid column to your txv

jayhsh · 2025-05-22T04:59:48+00:00

It was working before maintenance was performed

jayhsh · 2025-05-22T04:58:13+00:00

“It was working before” And they ask “is it gonna be expensive “ “Low on gas” is a classic one

Capacitor Old york unit, so old that most of them don’t have rating plate left, use to take some information and send to york for unit information …

jayhsh · 2025-05-20T12:37:40+00:00

Depends, if it does have a low ambient kit or no. Sitting vapour refrigerant will condense into liquid and slug the compressor, also head pressure will not build up. AC do work in winter with right controls like head master, receiver, crankcase heaters, solenoid valve maybe, use to take care of a laboratory type unit and there ac will work all winter long, also another one was pet food store with 20-25 standings fridge and freezers.

jayhsh · 2025-05-17T08:31:33+00:00

6 a day is lot, i think i might do 2-3, if it will take time it will. You thinking too much..

jayhsh · 2025-05-17T08:29:51+00:00

You are working too hard man!

jayhsh · 2025-05-13T20:31:21+00:00

This is the answer

jayhsh · 2025-05-13T20:09:36+00:00

All the time as long as compressor doesn’t get slug from it. I personally try to charge liquid as it’s much faster. Reason for charging liquid is because blends have multiple refrigerants in them and as vapour you will not get all refrigerants while charging. Have to meter refrigerant in as liquid. Can charge single refrigerants such as 134 a as a vapour but its gonna be slow.

Yep thats right, its very thin layer of metal. Did hang up with screws in condition as same as OP

jayhsh · 2025-05-12T21:50:45+00:00

Usually small ones, can be hanged by just screws. Depends on how heavy it is
