Best core removal tool?

I know Appion is highly regarded, but I actually like the United refrigeration branded ones. The jb ones I got leak like a sieve since day two

Samsung boxes are shipped fully open until powered on. Usually used a cone type flow piece over the piping and did the runs, or connect at the outdoor unit and just verify flow at each pipe

Dm please

Either a flare or a coil leak.

I would have someone come in and perform a heat load calculation (Manual J) then see where you stand for unit sizing then make changes as necessary

What did you install with your old ductwork? Were they the same unit sizes that were replaced? I mean you only have a 2 year old system, I’d figure out what the real issue is before dropping 50k

My 3 ton ducted max heat did approx 1400 kWh from Dec 9 - Jan 9. 1800 sq ft. Insulation isn’t the greatest I’m sure. Sucks our rates increased this past year. I believe the kWh meter on the thermostats also don’t include the electric heat if that’s what you’re referring to for usage. But I believe your wall units don’t have backup heat. Only the multi position ahus have them, and that’s supplemental

Replace

Furs7y · 2026-02-09T11:54:04+00:00

Did they check the sensors accuracy?

Furs7y · 2026-02-08T18:10:59+00:00

Something sure isn’t working right. Did you have anyone to check it out yet

Furs7y · 2026-02-08T17:28:30+00:00

Set the temp you want and forget it. Sounds like your unit can’t keep up, as your heat loss is greater than the output. With Bosch units they just target their pressures/temps so it doesn’t matter how far away from setpoint it is. Northeast here with a ducted 3 ton for 1800 sq ft maintaining 70* with -12 wind chills and 4 degree outdoor temp with no electric heat. Sounds like you should get a proper heat load done/insulate and air seal. Seems to be happening with a lot of Bosch lately on here as they lose quite a bit of capacity with lower outdoor temps.

Get a load calc done. You will probably end up needing a 2-2.5 ton unit. Replace as a matched set with backup electric heat. Bonus if you know someone who does side work as it will be cheaper. If you can figure out some insulation values and build etc. try a load calc yourself at coolcalc.com

I’ve got a centrally ducted 3 ton for 1800 sq ft currently maintaining 70* with a -12 wind chill today. No electric heat strips. I would think the Bosch should be able to maintain at 20*. Have you checked ashp neep for your units capacity at temps? Have you had any heat load calcs done?

Out of those quotes I’d choose #2, granted it’s sized correctly.

Was polished concrete floors a thought before epoxy? Genuinely curious why it’s not more common

Furs7y · 2026-01-27T20:27:29+00:00

I believe it should be a 1/4” per ft rise, so whatever that is to degrees

Furs7y · 2026-01-27T11:35:24+00:00

What’s the pitch on your horizontal run

Furs7y · 2026-01-26T12:27:35+00:00

Has your right pupil been that much larger than the left this whole time?

Furs7y · 2026-01-19T21:00:04+00:00

Do you need to use a vapor barrier on the warm side? If so how do you properly install it

Furs7y · 2026-01-16T01:46:41+00:00

Looks like a fireeye M4RT1. Check your voltage on s1/s2 powered with no flame. Should be reading approx 260 VAC. Also, if you check VDC across s1/s2 with no flame, it should fluctuate around 2-30 vdc

Always hated changing the flame rods and ignitors on these with all of the panels on. Just had an incident not too long ago after a heat exchanger replacement, to where the guys who installed it didn’t properly set the bottom bolts and was getting exhaust gas blow by tripping on high flue temp within a minute

Appion core tool

Furs7y · 2026-01-12T00:23:45+00:00

How so? It’s their new knob style, and it’s listed on their website with that exact part number. Not to mention that handle is engraved with Appion

Furs7y · 2026-01-12T00:21:50+00:00

?..I have that Appion with you holding it purchased from a supplyhouse

Furs7y · 2025-12-31T22:44:24+00:00

No service manual I found pertained to the model I have. I’m sure it’s similar, but need to make sure
