Why Choose Wall-Mounted?

If you have one or more rooms without exterior walls or windows, a wall-mounted ductless split system will work beautifully. The indoor air handler is sleek, unobtrusive and quiet. You need only a 2” clearance from the ceiling, so you’ll have lots of placement options. All systems come with a remote control, so even units high on the wall are easy to operate. There’s also an optional wired, wall-mounted controller for models over 18000 Btu. See our selection of wall-mounted ductless split systems.

Choose from single-zone cooling models, single-zone heat pumps that cool and heat, and multizone heat pumps that individually cool and heat multiple rooms.

 

*Wireless LCD Remote is included with each Indoor Wall Mount Unit

 

Why Choose a Ceiling Cassette?

The indoor air handler mounts completely flush with the ceiling and only the grille is visible. However, a minimum of 9 ¼" of clearance above the ceiling is required, which makes it a great solution for drop ceilings.  Each ceiling cassette has two branch ducts that can be run to adjoining rooms; an additional fan is required for each branch. So if there’s adequate clearance in only one space, a ceiling cassette can still cool and heat up to 3 rooms from a single system.  Friedrich ceiling cassettes have an energy-efficient SEER of 15.0, yet provide up to 2 tons of cooling capacity and over 24000 Btu of heat.

 

*Wireless LCD Remote is included with each Ceiling Cassette Unit  

 

Why Choose Concealed Duct?

Concealed duct units are mounted in the ceiling of rooms where minimal visibility of the heating and cooling system is desired. Ideally suited for applications where wall space is limited or the ceiling is the preferred installation location with only a small vent opening visible in the ceiling. Powerful, quiet compact and energy efficient, the installation will require minimal ductwork.

 

*Wired, 7-Day Programmable Controller is included with each Concealed Duct Unit.

Cool and heat up to four zones

Like other ductless models, a wall-mounted system consists of an outdoor condensing unit and 1–4 indoor air handlers connected by refrigerant and electrical lines that run through a 3" opening in an exterior wall. 

  • Single-zone cooling: This system has one outdoor condenser and one indoor air handler that cools one room. The new 115V models have cooling capacities of 9000 and 12000 Btu, and the 230/208V models range from 18000 to 33000 Btu.
  • Single-zone heat pumps: This system has one outdoor condenser and one indoor air handler that cools and heats one room. Cooling capacities range from 8500 to 22000 Btu, and heating capacities range from 10000 to 27600 Btu.
  • Multizone heat pumps: This system has one outdoor condenser and up to four indoor air handlers that cool and heat individual rooms. Each indoor unit is separately controlled for customized comfort settings, and units can be turned off in unoccupied rooms to save energy. Multizone systems are available in numerous configurations, with total system capacities between 18000 and 36000 Btu.

The advantages of Inverter Technology

Friedrich wall-mounted ductless split systems feature variable speed compressors and fans (called Inverter Technology), which reach the desired temperature faster, maintain it more accurately and reduce energy consumption with fewer compressor startups.  Our wall-mounted ductless split systems can cool and cool/heat 1-4 zones. Multizone systems let occupants independently set the temperature for individual comfort. Units in unoccupied rooms can be turned off to save energy.

Hard-to-find 115V 9000 and 12000 Btu/h models are available. Capacities up to 3 tons.

 

Available in cooling-only and cooling plus heat pump models

  • Cooling from: 8500-33000 Btu
  • Heating: 10000-27600 Btu

SEER

Seasonal Energy Efficiency Ratio (SEER) is a measure of cooling over an entire season. It is determined by comparing the amount of cooling produced in BTUs in relation to the amount of electricity used. A higher SEER means a system is more energy efficient and would provide comfort at a lower utility cost than a lower SEER system.

SEER
17 SEER
Energy Efficiency Ratio

The measure of air conditioner efficiency at its maximum load

Energy Efficiency Ratio
12.3 EER
Coefficiency of Performance

Coefficient of Performance is the efficiency ratio of the amount of heating or cooling provided by a heating or cooling unit to the energy consumed by the system. The higher the Coefficient of Performance the more efficient the system. Resistance electrical heating (such as electric baseboards) for example has a Coefficient of Performance of 1.0

Coefficiency of Performance
3.3 COP
Heating Seasonal Performance Factor

A measure of heat pump efficiency while in a heating mode. The higher the number the better the energy efficiency.

Refrigerant

Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.

ENERGY STAR® Qualified

Products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR specifications. The EPA establishes these specifications based on the following set of principles:

  • Product categories must contribute significant energy savings nationwide.
  • Qualified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
  • If the qualified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings, within a reasonable period of time.
  • Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by multiple manufacturers.
  • Product energy consumption and performance can be measured and verified with testing.
  • Labeling would effectively differentiate products and be visible for purchasers.
