I wish he texted my partner the other pictures too instead of just this video but this was all he ended up sending. It's just shit like this all up in there.
I know we're getting salesman'd at but I think we might fall for it because the first guy quoted like 18-20k to replace the gaspack unit and replace all the duct work and this second guy, their initial quote for a larger 2 stage gaspack unit plus all the duct work was something like 22-23k. But then he calls his boss and his boss is on speakerphone saying, essentially, "please give us work please we're so desperate for work please we beg you" (not in those specific words) and dropped it down to 17k. Then he asked if there was a number that would make us agree and my partner said 15k and he went to talk to his boss and was like, yeah, no, we can do that, if we agree to set up an installation tomorrow. which is kind of a red flag because that's a high pressure salesman tactic. But also the guy on the phone was like "I'm going to do high pressure tactics because we really need the work." I guess because the weather has been unseasonably mild the last two weeks they haven't been getting as many calls, so their work crews have literally nothing to do right now.
Idk, it seems like a good deal but also looking at prices for similar units (3 ton 15 SEER2 gas packs) it's like 5000-7500 for the unit itself. Is 7500 in labor to install it, plus re do the ducts, reasonable? I think... maybe? They said something about having two crews out here to get it done in 1 day so I imagine they have to pay a lot of people?
I am also leaning towards doing it because our current unit is 9 years old and it's apparently been struggling the entire time. The guy today said it needs 1200CFM of air flow, but only having one 16x20 return vent restricts it to at most 700CFM. If it weren't for all that I'd be leaning more towards "let's just tape up all the gaps in the ducts and hope it doesn't break soon," but like, I dunno man, what if we put in all that effort and then it dies anyway. This is too much for me to deal with 
Ductless Mini splits work by moving the refrigerant through compressed lines, rather than blowing the air around. Since you already have space in the ceilings and walls currently occupied by ducts, you can probably get a ceiling cassette style rather than the big wall units.
A lot of these mini split systems are also heat pumps, which are more than 100% efficient at heating down to most exterior temperatures when compared to gas or electric heating.
