FlytrapCare Carnivorous Plant Forums

Just gonna toss my insights in here.
My initial look at the pics led me to mineral burn. Then, reading through your subsequent posts, provided me with a few thoughts.
Light. While three hours a day is not optimal, as long as the rest of the day is spent in bright, indirect light, it should be OK. If your temps are consistently that high, you don't want it in direct sun during the hottest part of the day anyway.
Media. Although you've only had it about a year, you don't know how long the plant has been in it. Media gets "sour" and anaerobic, plus minerals can build up. If it was watered with tap water prior to you getting it, it could already have a build up. Fresh, known media can help solve that.
Water. Water from the AC condenser is usually very low to zero in mineral content, but many condenser coils and vanes are copper or an alloy, and these metals will shed ions into the condensate. Though most plants, even carnivorous plants, can benefit from these trace metals, too much is not good. Carnivorous plants are more sensitive to them, copper especially, and (I can't find where I read this) as little as 20 ppb copper is pretty much the threshold for toxicity in carnivorous plants.
Good, direct AM sunlight, indirect/shaded/dappled light from about noon for the rest of the day.
I would suggest a repot into fresh, known, proper media.
I would also try to find a new water source. Rain might be scarce in your area, perhaps get a TDS meter and test your tap water. It may be OK for your needs. Or look for sources to get distilled water like a grocery store.

In its native range, it will experience 35°C from time to time. If that is going to be the temp every day, I'd do wat I previously suggested. Direct AM sunlight, indirect from noon on so it's in the shade for the hottest part of the day.

Your AC water may be just fine, but it could have also started the adding of metal ions into the media to a point where it wasn't harmful. But starting to use it again, adding more ions, may now be increasing those ions to harmful levels. While any water is better than no water short term, if you can't get appropriate water, having these plants may not be a good choice.

Try to find an inexpensive source, or increase your rain water storage. You can also get a TDS meter (~$10 US on Amazon) to test your tap water. It might be OK to use. My tap water fluctuates from about 90 to 130 ppm TDS, however it's low in nitrates, sodium, potassium, magnesium, calcium, and other minerals that I can switch to that when my rain water reserves run out. If your TDS is low, see if you can get a water quality report to see the contents of your tap water.

See optique's post. Not risky, just a little time consuming.

Don't divide it unless it falls off on its own, or very easily separates.

1:1 or 2:1 ratio of peat:perlite is what most people use.
