Unexpected heat waves no longer mean walking in to an uncomfortable home and Fido and Fluffy are protected too. You can even save money on your electric bill by eliminating waste.

    Control also means access to built-in energy management schedules as well as the ability to customize multiple 7-day programs to fit your lifestyle.
    And, Kuhl is the first Smart Grid enabled room air conditioner.

  • FriedrichLink .

    FriedrichLink is the program that lets you access and control your K hl unit remotely from your smartphone, computer or mobile device. On FriedrichLink you can register your unit and then create schedules, make adjustments, set utility functions and even group multiple units for more centralized control.

  • Smart Grid Capable.

    Kuhl is the first room air conditioner to be Smart Grid capable. Smart Grid is a network that brings electricity from power stations to consumers using new technologies that allow power companies to adjust electrical loads of residential users. Check with your local electric company to learn more about Smart Grid programs in your area.

  • Kuhl Construction.

    For over 125 years, Friedrich products have been renowned for their commercial-grade, built-to-last design. Advanced engineering, high-end materials and components, and rigorous product testing are just a few examples of Friedrich's commitment to quality. When designing Kuhl, our engineers challenged convention to develop the very best window air conditioner on the market. Kuhl incorporates high-end materials like heavy-gauge galvanized steel, rifled copper tubing, and high-tech aluminum fins. Kuhl also uses the most durable components to extend the life of your air conditioner, including fully enclosed fan motors that seal out dirt, and powerful, energy-efficient compressors, which make Kuhl as tough an air conditioner as we've ever built.

  • Kuhl Quiet.

    Kuhl has been engineered for quiet operation. Materials have been chosen because of their sound-absorption properties and every moving part has been braced and insulated. For example, extra thick rubber grommets absorb vibration and reduce noise inside, while steel inner walls and extra dense insulation block outdoor noise. Rugged hardboard side panels help reduce noise and keep out light. The unique air path is more streamlined, drawing air through the sides, away from moving parts. And our larger discharge vents allow for smoother airflow, delivering maximum conditioned air quietly.

  • Kuhl Purity.

    Kuhl's advanced dual-stage filtration system removes allergens, odors, ozone and other impurities from the air. By combining the optional carbon filter with the standard antimicrobial filter, Kuhl achieves lab-tested superior air filtration with ratings as high as MERV 6. Use the fresh-air vent and the exhaust vent for additional air-quality control.

    When both vents are closed, Kuhl cleans and conditions the air in your space. Open the fresh-air vent and Kuhl purifies and conditions a moderate amount of outdoor air along with the air in your room. Use the exhaust vent to release stale air and odors outside.

  • Kuhl Comfort.

    The most comfortable temperature is the one you never notice. K hl uses four built-in environmental sensors to more accurately monitor indoor and outdoor temperatures so that it can maintain your ideal settings.

    Kuhl models have the ability to cool or heat as needed so units can operate year-round. And, like the most advanced central systems, Kuhl has four sensors, which allows the unit to automatically switch between air conditioning and heating functions to maintain the desired comfort level. You won't have to lift a finger.

    Plus, Kuhl's air flow systems are tested for powerful and precise air distribution which means faster cooling when you need it most.

    Pink Diamond
    Classic Beige
    Black Onyx
    Designer White Kuhl Colors.

    Kuhl's streamlined modern design in Cool Grey can blend in with any d'cor. Or coordinate a look that complements your space by using any of the six colored front covers (sold separately) including Deep Red, Cobalt Blue, Pink Diamond, Classic Beige, Black Onyx and Designer White .

  • Kuhl Efficiency.

    Kuhl operates up to 20% more efficiently than many competitive units, delivering more cooling capacity while using less energy. Further, some models meet or exceed ENERGY STAR® guidelines. Kuhl uses R-410A refrigerant, and all models even adhere to strict European RoHS requirements. Being energy efficient is better for the planet as well as your wallet.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
