Chiller or.....

[reefer403]

quick question for you guys. Just started my first saltwater 3 months ago. Things have been good until yesterday when temps got a little high here. My house gets quite warm. I am wondering if I need a chiller or would an A/C unit work to maintain as it hasnt overheated on the mild days. Was just thinking I could kill 2 birds with one stone and get the A/C that would benefit my household as well. Any advice is appreciated!
