From the Manufacturer

The M18CF Ductless Split System features a new level of system flexibility and control at your fingertips with the Advanced Inverter Technology. Inverter Technology lets you reach the desired temperature FASTER, maintain it MORE ACCURATELY, and REDUCE energy costs. It eliminates the constant compressor start-ups/ shut-downs required to maintain the set temperature with traditional technology. It controls compressor rotation speed precisely and adjusts capacity to meet demand, which in turn reduces energy consumption.

Inverter Technology allows each system to adjust capacity and cooling output to provide only the amount of cooling needed at a given time. For example, an 18,000 BTU/h system will operate even more efficiently as a 15,500 if that is all that's needed.

All of the Friedrich ductless split systems exceed the new 13.0 SEER requirements. And, a full one-third of the models have super high ratings ranging from 16.5 to 19.0 SEER.

Units are fully programmable, so setting and keeping the desired comfort level is a snap. Smart features like "Sleep Timer" and "Energy Saver" allow the user to program the unit for optimum energy savings. The continuous "Air Sweep" auto louvers gently distribute cool or warm air throughout the room.

A new level of system flexibility and control is at your fingertips on Friedrich single and multi-zone systems. You'll have more options for optimum comfort, control and energy savings.

Over 20 single, dual, tri- and quad-zone systems provide a wide range of heating and cooling options for even the toughest remodels, additions and improvements.

The Friedrich ductless split systems have the advantages of a ducted installation without the high material and labor costs. Absolutely no ductwork is required, so most systems can be installed and running in a few hours.

Warranty Info

Warranties on mini split air conditioners only include parts and do not include labor. The licensed HVAC Technician who installs your air conditioner should always provide you with a labor warranty (preferably for at least a full year to compliment the manufacturers' parts warranty).

AJ Madison will only finalize a Mini Split (Ductless Split System) purchase with an authorized HVAC Technician. AJ Madison recommends the installation of a mini-split system to be performed by a trained and qualified HVAC technician with the proper knowledge and background. A trained technician will be able to judge the best location for the air handling (evaporator) unit and also the correct size for the area the unit will heat and/or cool. For assistance with all your technical needs please contact our technical department at hvactechsupport@ajmadison.com.

Should you experience an issue during the installation or the initial startup of a unit please do not contact the manufacturer. You should have the technician that installed your system contact either AJ Madison or the manufacturer. We cannot accept any service or warranty calls from anyone but a licensed HVAC technician. We have a full technical support team available to help you throughout the installation process.

AJ Madison, Inc. cannot be held liable for improper installation and operation of any product purchased from our company. Should a warranty issue arise in which parts will need to be replaced, an installation receipt will be required along with your AJ Madison sales receipt. Failure to provide a receipt or invoice may result in the warranty not being honored.
