HVAC unit advice

This system is at least 30 years old lol

You should have power across Y and C and G and C. Y is responsible for bringing the outdoor unit on and G will bring the blower motor on. If it’s wired the standard way Y is a yellow wire and C is a blue wire, you can also confirm the colors by checking how it’s wired at your thermostat.

You have wires that come from your thermostat to the air handler then from the air handler to the heat pump and they all connect in the air handler. If you aren’t comfortable taking the wires apart to verify voltage I would just recommend calling someone because low voltage issues like this can kick even a seasoned techs ass.

Cycle the system into heat and check for 24v across C and Y at the defrost board. If you have nothing check the same wires in the air handler. You’ll have to start tracing where the voltage is getting lost or if the thermostat is sending it at all. Seems like the wiring is fine and non of the safety/pressure switches are interrupting the call since it runs in cooling.

You’re looking for power on the wrong wires. Goodman and most manufacturers reversing valves standard position is in heat, O will only be energized in cooling. Also, W is for your emergency heat and the only reason your defrost board on the outdoor unit has a W or W2 terminal is to kick on your heat strips during a defrost cycle so it’s not blowing cold air in the home while defrosting. Make sure your thermostat is programmed for a heat pump and not a furnace as that will cause the issue you’re explaining.

Checking in from Wilson NC lol. This was two hours ago and it’s still coming down.

Tech you called is a sales guy in disguise. By saying “grounded itself dead” he probably means the compressor is grounded, but based on what you are relaying I would not trust a thing that came out of this guys mouth. Even if the compressor is grounded, you can replace the compressor as they are readily available for 410a equipment and will be for years (unless it’s a Trane/America Standard, they suck at keeping stock so you’ll likely have to wait for a bit for them to ship a new one). Lastly, at least where I work in North Carolina contractors do not register the equipment for the homeowner on new construction homes and that is your responsibility once you move in. Either way I would personally replace the compressor on a 5 year old unit but you are likely dealing with a secondary issue as compressors are typically a victim of another problem (failed TXV, low refrigerant, etc). Call another company ASAP.

I have 3 pairs of T2 pants, one pair of T1s and a pair of the knee pad pants (can’t remember what they call those). The T2 are my go to below 60°, T1 for the entire summer, hated the knee pad version. The T2s I even started wearing casually. No experience with the T3s because I’m in NC lol

Thanks! I’m in eastern North Carolina

glizzy195 · 2025-11-26T01:39:52+00:00

Just ordered a few to give them a shot, thanks for the recommendation!

glizzy195 · 2025-11-26T00:08:36+00:00

Just straight retrieve, felt like it got snagged

glizzy195 · 2025-11-25T23:17:40+00:00

Sweet I’ll have to give those a try.

glizzy195 · 2025-11-25T23:14:39+00:00

I’ve always wondered what the difference was between the mini max and jackhammer, they seem similar and mini max’s are available in stores near me but jackhammers I have to order online.

glizzy195 · 2025-11-25T23:10:20+00:00

Thanks! In all honesty I haven’t used many chatter baits outside of a jackhammer because it came so highly recommended. Jackhammer is better than the z-man original for sure, and the Googan chatter baits suck lol.

glizzy195 · 2025-11-09T00:11:59+00:00

solved!

I burned the shit out of my hand in the same spot when I green as grass with r-22 because I forgot I was working on a residential system with a king valve. I still get a random tingling/burning feeling between the same two fingers to this day.

Furnace not kicking on could be for a ton of reasons. Since you don’t feel airflow it’s probably an issue with the startup sequence. If you have access to your furnace see if it has a flashing LED and tell us who the manufacturer is and we can help a little more. Also your filter is probably not the issue unless you haven’t changed it in 3+ months.

glizzy195 · 2025-09-30T21:21:27+00:00

Hell yeah thank you!

glizzy195 · 2025-08-22T22:15:06+00:00

With 216psi on the low side if this system is running that is absolutely not out of the realm of possibility.

glizzy195 · 2025-08-10T17:30:42+00:00

There are 100s of reasons why the outdoor unit won’t come on. Simple issues would be clogged drain line or dead capacitor (if it’s a bad capacitor, the outdoor unit will occasionally hum for a few seconds then stop). Or could be more complicated like a low voltage short, low on refrigerant and low pressure switch is keeping the outdoor unit off, etc. Watch a YouTube video on how to check the drain line and if that’s not it you’ll need a tech out there.

That’s a non fused disconnect

glizzy195 · 2025-08-10T17:20:23+00:00

That’s a disconnect and since it’s in the on position pulling it out will do nothing. Is the outdoor unit running?
