I returned an extra $2000+ heat pump to home depot.
Backstory, I ordered one online and it arrived at the store for me to pick up a week later. They had two pallets full of boxes wrapped in that saran wrap stuff, with two Estes freight shipping documents. They had my name but the HD store's address on them. Clerk insisted I take both, because "there are inside and outside pieces." Forklift dumped them in my truck bed and I drove off into the night.
I get home, cut the saran wrap off, unload now-manageable pieces into my garage. Sure looks like I have two of everything, maybe even three.
So I hold onto everything in case it comes up during the installation. Do the installation, get it running following directions, yadda yadda.
The leftover pieces appear to be a two-room setup with one outside condenser. Oddly, the part number is not carried by Home Depot! Special order? You got me.
I sat on the stuff for another week, it was like three weeks by this point. I was wondering if they'd notice somewhere down the chain and telephone me. Never happened. So I called HD online customer service. They have no idea what to do but say bring it to the store.
So I pile it all back in my truck and bring it to the manager's attention. "oh, yeah, someone else ordered one but we couldn't find it. Thank you." Without any receipt or paperwork, the store was now plus-one unit.
