Any suggestions on a good a/c

In Florida, only a licensed contractor can charge the A/C. You can buy precharged A/C's and the lines, too.

Yep those come pre-charged and ready to plug into each other via connector. Still hydro is need for each unit though. so not as easy as it may look for those who don't know electrical work at all. But no gas guy needed.

That's still not bad though if a guy could do everything but the electrical, one would still save a ton.

The 12000 btu model is 115v and plugs into a wall outlet. Does one outlet not run both inside and outside units?

I see these two piece units are used outside of North America a lot. Great for folks who want to cool off an interior room or only one room. Also good for those without forced air service in the building.

Ive also been thinking about cooling as new laws will most likly permit lower plant counts so il need to go bare bulb + co2 instead of fresh air and hoods. When search mini splits for Canada im finding a few 5 ton units. From 3500-5500. All of them contain 2-4 zone handlers and all lines precharged for DIY. Electricial wouldnt be hard probably a 40A circuit wired up like a lighting controller althought i would get both done by a electrician for due dilligence.

When i set up again (legally i hope) il have a 100% licensed technicians doing everything and automatic fire extinguishers above my electrical area.

You will be able to sleep better at night going that route.

What make are the 5 ton units your looking at?

Fire suppression over the electrical is a waste. Turning the power off is the best approach to electrical fires. Trust me.

Extinguishers over areas or objects that would continue to burn after the powers off.

If the electrical is correct you dont really need it...

Not using it yet. Me and my wife have a new place being built so I'm doing a lot of window shopping.

Make sure it has a auto restart feature. For ex if you loose power it will reset to desired temp you set it at. if you dont have that option when you loose power it will not cut back on to desired temp and when you get home its 110 degrees in your room

I have some of the Fujitsu 2 ton heat pump units which have worked great.
But after 2-3 years the aluminum fins on the inside unit rotted away and I just replaced two of the head units.

One thing to consider is the outside operating temp. The 2 ton single zone units are rated to -18 c and I have found they work in even colder temps if the outside unit is on the south wall, not facing the cold north winds.
The one unit I have on a west wall will stop before the south facing units.
Most multi zone units are not rated to work in real cold temps from what I have seen.

I heard Mitsubishi will work down to -40 but I think that is in heat mode no cooling.

Dual zone I think. You can attach up to 3 splits to it, is that what it means? Has both a/c and heat.

splits..you mean air handlers? the indoor component?

If you have heat and cooling, that's a heat pump.

I haven't come across a single zone unit over 3 tons. The dual zone, or more,. are just stacked units...for example a dual zone 5 ton is two 2.5 ton units in one...30,000btu's for each zone.

How well does your heat pump cool in the winter?

I've read there is low ambient temp models.

Yeah probably mean air handlers, sorry just an owner not an installer lol.

To be honest I've never used the heat, I just use my natural gas co2 generators for heat.
