Buying modern machines has been an ongoing learning experience for the last 20 years of my life. Ever since I went and purchased a lemon refrigerator from a store with a 2 day return policy, I have felt easily cursed with immense purchases. I was living with my mother while finishing university & I had convinced her to let me take care of finding a modern fridge after our seasoned one died following 23 years of solid performance. My ego got the better of me entirely & I jumped on a sale I saw at a local immense bog hardware store. Using name recognition as the sole source of trust in this huge purchase, I pulled the trigger separate from doing the minimum of due diligence on my part. At the core of it, I should have made the decision to call before buying it online so I could ask for a clear explanation on the store’s return policy regarding this particular brand’s machines sold at that store. This memory has haunted me a great deal since, so much so that I have been stuck trying to make the choice on getting on the right portable cooling machine to buy for my small studio apartment. The many windows I have are completely too small for a traditional window cooling machine, & a ductless mini split is simply too far out of my budget range until I manage to get a better task. This led me down the path of looking for portable cooling machines. Since these are just indoor package system ACs, they still have a tepid condenser that needs to be cooled down. My choices are only single hose machines that pull air conditioned air back into the equipment to cool the condenser before being pushed out the exhaust hose through a window or a port in a wall. Two hose systems are seriously more efficient. Instead of wasting air conditioned air to cool the condenser, it has another hose entirely to pull in outdoor air for this necessary task. Although more high-priced, a multi-hose machine seems a much better fit for long term use.
