No window unit.

did you get this model: SENA/24HF/Z ?

I'm curious about these units now. The Senville website has none of the usual charts and/or spreadsheets that depict performance. Without comprehensive performance data, how would a competent engineer, architect, or HVAC tech size the unit to the space and heat load? They wouldn't.

Looking straight at their website, the model cited quotes only 3 performance figures: SEER 20, EER 12.5, and HSPF5 8.4. The EER rating and maybe the HSPF5 I could possibly believe, in certain conditions, but I would have a hard time pulling the trigger on a not cheap (relative to window units) system that seems to beg to be mismatched to specific buildings. Yes, I know they are priced hundreds of dollars cheaper than established brands of similar rating.

I hope it serves you well. Please follow up on this unit if you can. Given the lack of real-world performance data, your information would help fill in the blanks for many inquiring minds. Not to mention the other unit of the same brand you already operate.
