For prolonged periods of time this can shorten the lifespan of your fish. Higher temps can result in death.
You can bring the temperature down by turning down the temperature in the house, having a fan blow across the top of the tank, turning off the lights, blocking sunlight into the room, increasing water changes, floating ice packs, or investing in a chiller, either DIY or a manufactured chiller.
The DIY project involves getting a small refrigerator, the type used in dorm room, drilling two holes in the sides, running tygon tubing in, coiling the tubing is a container of water, running the tubing out, and then pumping the water back to the tank. The coiled tubing is used to modulate the temperature.
