*IMPORTANT! This is an indoor air handler ONLY.  You must have a matching Friedrich outdoor condenser to complete a functioning system.*

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.

 

Concealed Duct Overview

Like other ductless models, a concealed duct system consists of two parts; an outdoor condensing unit, and an indoor air handler installed in the ceiling or a furr down. The indoor unit and outdoor unit are connected by refrigerant and electrical lines that run through a 3" opening in an exterior wall. This system requires a licensed HVAC technician to connect the lines between the indoor and outdoor components.

The advantages of Friedrich Precision Inverter Technology

Friedrich ceiling cassette 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 and shutdowns. Friedrich Precision Inverter uses 1 Hz increments for near zero wasted energy.

Indoor Air Handler Type

Indoor air handlers come in three basic types: - Wall Mounted is easiest to install - Ceiling Cassettes are unobtrusive and offer some ducting to other rooms - Concealed Ducts mount behind walls, above ceilings or under floors and handle multiple rooms

Cooling Capacity

Cooling Capacity
12000 BTU
Heating Capacity

The amount of heat, rated in BTUs that the item can produce.

Heating Capacity
13600 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
17.5 SEER
Airflow Capacity

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.

Line Set Connection Type

There are two main types of connections for HVAC products brazed and flared. Brazed connections are typically used in standard split systems, and flare connections are typically used on mini splits and can be connected using a wrench.

Flare
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.
