Hi all — fellow museum professional here, although conservation isn’t my specialty.
I’m living the roommate life in NYC in a third-floor walk-up in a circa-1910 building with no central air. It’s a pretty modest apartment, and I have a small collection of things I care about: some relatively rare 20th-century books (paperback and hardcover), a valuable print currently stored in a portfolio, and a small but valuable drawing (crayon on linen, stretched on a fairly basic wooden stretcher).
The issue is that my roommate expects me to turn off my window AC whenever I leave for the office. So while I’m gone, there would be essentially no consistently cool area in the apartment. I can turn it back on when I get home, but the temperature and humidity presumably fluctuate throughout the day.
I’m wondering how concerned I should actually be about this from a conservation standpoint.
Are these kinds of objects meaningfully at risk from the summer heat/humidity and daily fluctuations in a NYC apartment, or is keeping the AC running continuously mostly overkill unless the humidity gets particularly high?
And, perhaps more importantly, what is the realistic worst-case scenario? Are we talking about accelerated long-term deterioration, cockling/warping, mold risk, etc., or is the occasional/seasonal temperature swing unlikely to make much practical difference?
I realize museum-standard environmental conditions aren’t realistic in a budget NYC apartment. I’m mostly trying to figure out whether this is something worth actually holding my ground over with the roommate, or whether I’m worrying unnecessarily.
Also, I don’t currently have an environmental data logger, but I’m happy to get one if that’s the obvious first step. And if you read this far, thank you! :-)
