Friedrich M18DYF Mini-Split Air Conditioner with Heat Pump

The Friedrich M18DYF Mini-Split Air Conditioner with Heat Pump features a seasonal energy efficiency ratio of 16.5 and a 12.2 EER rating for efficient cooling in your bedroom, home office, living area, or garage. Great for homes without ductwork or apartments with limited window space, the Friedrich M18DYF provides indoor comfort and efficient operation in any season.

The Friedrich M18DYF includes two air handlers that provide a cooling capacity of 9,500 BTUs and a heating capacity of 11,000 BTUs in each zone. This multi-functional air conditioner not only cools and heats your home, but it also provides fan-only operation and a dehumidification mode. The fan mode includes three speed settings and each air handler included with this ductless split system extracts 2.9 pints of moisture per hour.

Product Benefits

• Programmable Timer: The 24-hour timer allows you to automate operation on your Friedrich air conditioner to maintain your designated settings while you’re away or asleep.


• Auto-Swing Louvers: Each indoor air handler features air sweep louvers. To experience maximum comfort, use the air sweep function to direct cool air in an angle that best accommodates your needs.


• Reusable Air Filter: This mini-split system is equipped with two washable air filters that have been treated to prevent mildew buildup. Basic cleaning with warm water or a vacuum cleaner is recommended for every three months.


• Sleep Mode: The sleep function keeps your space comfortable in cool, heat, and dry mode and it maintains a pleasant room temperature with quiet operation while you rest.


• Frost Control: During low-temperature operation, frost may begin to collect inside the air handler. In the event of frost buildup, the compressor will automatically shut down until the frost melts, protecting the unit from any damage.


• Minimal Upkeep: In addition to user-friendly operation, this dual-zone ductless air conditioner features hassle-free maintenance. To preserve your Friedrich mini-split air conditioner, wipe the front panel of the blower unit with a cold, damp cloth and clean the reusable air filters periodically.


• Automatic Restart: In the event of a power failure, the Friedrich M18DYF Ductless Air Conditioner will automatically resume operation in the last programmed setting once the power is restored. This function not only protects the compressor, but it also prevents circuit breaker damage.


• Quiet Operation: This ductless split system operates efficiently around the clock while emitting minimal sound. Because the condensing unit is positioned outside your home, the indoor blower is virtually silent for little to no noise disruption in your indoor environment even on the highest setting.

Inverter Technology

What sets Friedrich ductless air conditioners apart from typical air conditioner systems is their innovative cooling process. This Friedrich mini-split air conditioner starts the cooling cycle with maximum power to cool your space faster using inverter technology. As heat is forced out of your space, the blower unit disperses cool air, lowering your room temperature to a comfortably cool level. This efficient cooling method helps you reach your ideal room temperature right away while conserving energy. Unlike traditional air conditioners, which constantly cycle the compressor on and off causing uncomfortable temperature fluctuations, the Friedrich M18DYF Mini-Split AC accurately accesses your current room temperature and uses the appropriate fan speed to maintain a comfortable temperature. Inverter technology helps you avoid the up and down cooling process of traditional ACs and it consumes 30% less electricity.

Dual-Zone Cooling

While central air conditioners distribute maximum cooling output to reach a desired temperature throughout your entire space, dual-zone ductless split systems offer targeted cooling in two designated areas. For efficient operation, you can install your mini-split system in the rooms you spend the most time in. With the dual-zone air conditioner, you can cool two bedrooms simultaneously or you can place one indoor blower in your bedroom and install the other unit in your living room.

This Friedrich dual-zone ductless split system consists of two indoor air handlers that you can control separately. Each blower unit is equipped with a remote control and a wall-mounted holder, allowing you to program custom settings for two spaces at one time. To prevent your programmed settings from being accidentally adjusted, every remote control has four distinct transmitter codes that only correspond with the appropriate blower unit. Multi-zone operation allows you to cool one space while dehumidifying another or heat one room while dehumidifying another. Additionally, you can adjust the cooling output to reach separate room temperatures.

Dual-zone cooling not only provides individualized cooling according to preference, but it also helps you reduce cooling costs. Having a dual-zone mini-split system allows you to turn the power off in an unoccupied space, while keeping another space comfortably cool. At night, for example, you can shut down operation in your living room and continue operation on the indoor blower in your bedroom while you sleep.

Installation Guidelines

This Friedrich dual-zone ductless split system includes the following installation requirements:
