If you keep your temps around 76 degrees or less it's good for your plants and would greatly reduce the risk of looking suspicious.
But seriously, you should chill, there are a million and a half reasons to have higher temps that have nothing to do with growing dope; computer servers, Bitcoin mining, coffee roasting, cooking, growing vegetables (people do that), various construction phases, a furnace, etc.
Police helicopters probably aren't flying around shining infrared cameras at your house, and even if they are, a hot spot doesn't prove shit.
