New to the Axolotl world

Hello everyone!
So, I have been doing endless research on how to to keep a happy Axolotl as a pet and I have run into a bit of a problem concerning the temperature.

My house in the summer gets 83 Degrees Fahrenheit (about 28 Degrees Celsius) at the most and I feel like there would be no way that I could keep a 55 gallon long tank cool just with fans. I have plans to rig up my own DIY mini fridge chiller but I haven't been able to find any information on whether or not it will suffice for that much water and if I should just break down and save up for a chiller.

My other concerns are just, getting everything I need and where to start with cycling. I know setting up a tank for an Axolotl is pretty simple, I would just like to hear about some recommended products and practices from experienced owners( cycling the tank with fish/fishless, filters, water and temperature management, ect,.) Anything you can think of I would really appreciate to hear.

Thanks in advance!
