temperature

I was at the LFS today just doing some browsing trying to figure out what kinda setup i want to go with for my first reef tank and the employee told me that since my house gets up to about 82 degrees in the summer (i live in Edmonton) that i would either need to buy a chiller or some kinda air conditioning for my house to keep my house cool. I was just wondering if the guy was just trying to convince me into buying uneeded parts from him or telling the truth
