My hats off to you for doing a DIY install. This is not a bad route to go if you enjoy/feel comfortable doing the work and don't care about air quality, smart thermostat integration, etc. Re contractors, we will have local contractor partners do the install and handle servicing, so you won't be left with an unserviceable system.

Are you able to say more about that? "We will have local contractors" sounds great but in my area I don't think you will be able to find anyone to work with you. The local contractors and supply houses have closed ranks to fend off internet sales. I can't even buy sheet metal from the local supply houses without presenting an HVAC license. These folks are seeing their livelihoods threatened by a looming shift toward the "appliance" model (which I for one surely welcome) so they would see partnering to service a model like this as slitting their own throats.

Agree 100% (I have my EPA cert and do my own installs)

Trying to bust into the HVAC company cartel will be the death of this idea. Most HVAC companies are highly local and have built their business around partnerships with supply houses and the US big-boy manufacturers (e.g. Carrier, Trane, Lennox). The Asian brands (Mitsubishi, Midea, Gree) have taken years to start penetrating the US market, and even then, many have done so through partnerships with the above US brands.

No reputable HVAC company is going to install a 'no name' dotcom branded unit that they won't be able to service with parts from their local supply house. They, and their suppliers, won't be getting the typical kickbacks or be able to mark up the unit costs and they likely won't offer any kind of warranty (at least on labor). To them, this is no different from Joe Homeowner ordering his MrCool/Goodman unit online and expecting them to install and service it for a low hourly fee. It's not worth their time or potential risk when the customer raises a stink a year later when that company reminds them they have zero warranty and parts aren't readily available.

There are ways of working with local HVAC contractors that provides value to them and doesn't just undercut their current way of business. Electric Air can provide lead gen, tools to support install, improved payment terms on jobs.

You're insinuating that doing the work yourself means you'll have poor air quality, poor thermostat integration etc. That's not true at all. If you've gone to the trouble to do a DIY install then you're now already experienced enough to install a heat-recovery ventilator to get fresh air into your home via an independent system. I installed my own ecobee thermostat with my heat pump and electric furnace and it works with HomeKit so is integrated with my entire ecosystem.

Reading their comment slightly overly charitably vs what was written (but almost surely in-line with what was intended), they were contrasting their unit that has a HEPA filter bundled as part of their unit and that is not part of the Mr Cool unit.

Exactly. There's lots of stuff you can stitch together yourself, and if you're a DIY person, its more fun/rewarding to do it that way. I think the majority of homeowners will want something that doesn't require doing the install themselves, or having to worry about overall system integration.

mr. cool has it's own smart thermostats/apps. you can use it also with nest/ecobee. with regards to air quality, usually this kind of stuff better managed by dedicated systems.
