Not only does the attic insulation need to be replaced/replenished but the wrong soffits were installed into the house. The house should have vented soffits. It could also use better venting in the attic. It was hotter than Hades up there last summer. When the first floor was 70 degrees Fahrenheit with central air, my bedroom remained at least 78 degrees and once neared 90 degrees. There are central air vents in my room; but, because it's basically attic space, it wasn't enough.
I spent so much time researching window air conditioners versus portable air conditioner and single hose portable air conditioners versus two hoses. I decided to buy a portable unit because it's easier to handle compared to installing and removing a heavy window unit. When it's not summer, I just roll the portable unit into my closet.
I went with a single hose unit because, after much reading, it seems that dual hose units are most effective when the temperatures are over 100 degrees Fahrenheit. We don't get a lot of those in Ohio. I choose this model because it was good for a 700 square foot area. While my room is 865 square feet, I still have the benefit of central air vents. It's the largest area recommended for any portable unit, and I trust the Honeywell brand.
Other concerns I had for using supplemental air conditioning in my room was the draw of AC current in an older home and the money it would cost to run the unit. I did have to get an electrician to put in a new AC outlet since none of my outlets are grounded and are all two-prong. This AC unit has a three-prong plug. I haven't blown the circuit using the AC; and, while I got this unit in the middle of my electric billing cycle, my bill was only $20 more compared to my bill last year. The average outdoor temperature of this last bill was one degree higher compared to a year ago. Also, with the whole COVID-19 pandemic, I've been home all day instead of away at work 50 hours plus each week. I'm cooking all my meals at home now compared to hardly any last year. So I'm using a lot more power versus last year.
It seems my whole-house air conditioner runs much less since I've gotten the portable unit. Perhaps keeping the attic cooler has resulted in the entire house remaining cooler.
This portable air conditioner is very efficient. It doesn't take it long to lower the temperature in my room. One thing to note is that once it's on, it's always running. When it's not pushing out cold air, the fan remains on. It does help to keep the air circulating. I've seen some reviews that complained this unit was too loud. While that's subjective, I don't agree with it. It's louder than my central air vent but not louder than a box, turbo or Dyson fan. I've included a video on the unit pushing out cold air which is a little bit louder than when it's just running the fan. I've also attached photos of my room to give a sense of the size of the room as well as the size of the unit.
I am so happy with my purchase. It is so pleasant in my room now compared to the sweltering heat last year. Sometimes, as I'm climbing the stairs, the air gets cooler instead of hotter which is a much welcomed change. I also sleep so much better now that I'm not drenched in sweat.
I highly recommend this air conditioner especially for those with similar conditions.
