Any HVAC installers on this forum?

Warmer, I am aware of this. Size the wire to the circuit breaker. 50 amp, #6 THHN or THWN. I install everything in conduit. Thank you for your input.

THHN is all you need, wire should be run and protected so it never gets wet

Have both. Conduit under house and liquid title outside of house. MTG

I didn't care for our heat pumps. We had two for zoned heating (2 story house). When the heating elements kick in due to cold weather you can watch the electric meter spin into overdrive. We had horrible luck with ours, one went through 3 compressors in 5 years. My wife at the time found the CEO of Lennox phone number and raised all kinds of hell. They ended up replacing the heat pump and air handler for free. Neither unit made it 10 years.

On the flip side, i installed a mini split (heat pump tech) at my hunting cabin and have been very satisfied with it.

I have found a LOT of Heatpump problems are simply the result of return air duct being too small. Heatpumps need A LOT more return air than regular systems, aka larger duct work. A 10KW heat strip on the reverse cycle is needed with most installations.

For a Trane heat pump, you'll usually need a 50-amp service to a disconnect. For most homes, 6-2 THHN wire should work fine, which means 2 conductors and a ground wire.
If you’re not sure about the wiring or need help with the installation, it might be a good idea to consult a professional. A West Ashley SC HVAC repair expert can make sure everything is installed correctly and safely.
Also, think about the distance from your panel. If it’s a long run, you might need to use a bigger wire.

Definitely a problem somewhere. We usually install a 2 stage unit if we zone. Maybe duct was too small in house? Not enough return air? Not making excuses, but we have very good luck with Lennox equipment.

It had a bad compressor from the the get go. I built the house and didn't know about it until the second compressor went out 2 years later. Just so happened the guy that came out is the one who installed the system and opened his mouth. I think I just got a lemon.

Speaking to different HVAC companies regarding a large mini-spit to accommodate our need. Explained that I would do my own electrical service as no need for some electrical helper to wire what I can do cheaper and better quality. Probably 6/2 or 4/2 THHN depending upon size of unit. Part of the problem is that this house initially was all electric. No duct work. So, a mini-split is a simple easy unit to install and I would build an enclosure high over the unit to protect from elements. MTG

Are you going single head or multi head minisplit?

I take it this is what a bot looks like?

Sounds dirty

 

[warmer]

Our industry is.

 

[Bigjay73]

Come over to commercial/industrial, no shady crap whatsoever

 

[buckbull]

If you are handy enough to run electric you are handy enough to install a minisplit. Only tools you may not have but need are a vacuum pump and valve core remover for minisplits. I installed mine. Not an electrician nor hvac guy.

Edit: get nylog too and a refrigerant testing tool. I bought the tool from amazon cheap.

Do those also.

Typically, a heat pump will require a 3-wire electrical connection. This consists of two hot wires (L1 and L2) and a neutral wire. However, there are specific circumstances where a 4-wire configuration might be necessary, such as for systems with dedicated ground or specific electrical codes in your area.

For professional electrical work and more HVAL leads, consider contacting a licensed electrician or HVAC specialist like Aroundwire. They can assess your specific needs and ensure proper installation and compliance with local regulations.

Looks to be a thinly veiled attempt to drum up business?

Ffs, do not use nylog!!! And you don't need a leak detector, I'm assuming that's what you mean by a refrigerant testing tool. Soap bubbles are all you need as a DIYer to check mini split connections. A pro will do a standing leak test with Nitrogen and a decay test with a vacuum, but who needs a pro

You mean the $5000 worth of tools and constant training for the last 41 years has been a waste of my time? Sure wish I would have found this out a long time ago.
