Six clicks: Ways to keep your tech, your home, and yourself cool

Nest, now owned by Google, may have been the first to release a smart thermostat to mass market, but Honeywell has decades of experience in thermostat engineering and design. 

Aside from smart learning capabilities and remote smartphone control, Honeywell's competitive offering, the Lyric ($235 street), provides the following features:

• Geofencing automatically regulates temperature when you’re away.
• Fine Tune considers temperature and humidity.
• Smart Cues keep you informed.
• Shortcuts create custom settings for recurring events.
• Motion-sensing display lights up on approach.
• Control the system from anywhere with your smart devices.

If you have a small apartment or don't have central air conditioning, you can still reap the benefits of automatic and smart climate control. A partnership between GE and Quirky has released the 8000 BTU Aros window-mounted smart air conditioner, which streets at about $270.

If you're looking to cool as well as heat your home in the most energy-efficient way possible, look no further than ClimateMaster's geothermal systems.

Geothermal HVAC systems use the stable, 55-degree temperature only a few feet underground to exchange heat, so they can be up to 80 percent more energy efficient than a traditional air conditioning and heating system.

In addition to being greener than their traditional counterparts, geothermal systems can provide hot water and also heat driveways to melt snow during the winter. They also have a longer operational life than a standard AC compressor.  

Looking to efficiently circulate air in a large space in your home or business? Big Ass Fans has the answer, with their Haiku and Isis designs ($1000+)

What makes these fans different and worth the money? Regular old ceiling fans have blades. Big Ass Fans have airfoils, designed like aircraft wings, which are aerodynamically inspired to maximize air velocities and stabilize air movement. This makes them far more efficient as air movers than conventional fans. 

And of course, like the other smart devices in this gallery, it's got an app.

Let's face it: Men's underwear can be downright stuffy during the summer. Frigo, a company that sports soon to be ex-Yankee Derek Jeter as one of its investors, has your solution. This high-tech ($30-$100) undergarment, which comes to you via the inventor of the Tempur-Pedic mattress, uses breathable micro-fiber mesh "zones" to keep your "package" nice and cool. 

Designed for motorcyclists and for people that have to work in hot conditions, this water cooled vest by Veskimo ($400) is similar to the systems that are used to keep astronauts from overheating in their space suits. 

The vest comes with a battery-powered or 12-volt pump with an external pack (which can be backpack- or externally-mounted) filled with frozen water bottles. Chilled water from the pack is circulated by the pump thoughout the vest in order to keep core tempertures low for as long as six hours at a time, even in 100+ degree outdoor tempertures.
