Air Conditioners Without Air Ducts

Ductless Air Conditioners: Cost-Effective Cooling Without the Fuss

The rapid advancement of modern air conditioning systems now offers users not only highly energy-efficient models, but also solutions perfectly suited for various types of spaces. Among these are ductless air conditioners, also known as mini-split systems or ductless AC units.

Hot Cold Air provides quality, professional services for the installation, repair, and maintenance of ductless air conditioners in Chicago and its suburbs. We are ready to help you choose the ideal air conditioning system for your home or business, considering architectural features, energy efficiency, and your budget.

What Are Ductless Air Conditioners?

Ductless air conditioners are climate control systems that don't require bulky ventilation ducts for distributing cooled or heated air. Their core design consists of two main units:

• Outdoor unit – installed outside the building.
• Indoor unit – placed inside the room (or several rooms), typically mounted on a wall. 

The units are connected by a small copper tube and a cable that pass through a small hole in the wall. This type of installation is quite simple and is ideal for homes where laying a complex ductwork system isn't feasible or desired.

When Is Ductless AC Installation Preferable?

When choosing an air conditioning system for a home, office, or commercial space, it's crucial to consider many factors. In several cases, ductless air conditioners (such as split or multi-split systems) become the optimal choice. Let's look in detail at when this is justified:

1. Absence of an Existing Ductwork System

• Typical apartments in high-rise buildings or older homes often lack space for ducts, making a split system installation the only viable solution. Installing a ducted system in such conditions would require additional construction work and significant expense. 

2. Partial Air Conditioning of Spaces

• If you only need to cool specific zones, ductless systems allow for localized cooling, saving on installation and operational costs.

3. Limited Budget

• Ductless systems are less expensive to install because they don't require extensive pipe and ductwork installation. This is particularly relevant for renters and property owners with budget constraints.

4. Quick Installation and Minimal Interior Disruption

• Ductless air conditioners are quick and easy to install. This is especially important in spaces with existing renovations or in commercial areas where tenants cannot make major structural changes.

5. Energy Efficiency and Zone Control

• Modern split systems are convenient and cost-effective. They allow for precise temperature adjustment in individual rooms, avoiding the energy waste common in ducted systems that cool the entire home.

6. Architectural Limitations

• In buildings with unusual layouts, high ceilings, or historical properties, installing ducts can be difficult or nearly impossible. In such cases, installing various models of ductless systems (wall-mounted, floor-standing, and cassette units) can be done without compromising the design.

7. Temporary Structures

• For temporary structures, cottages, or modular buildings, installing a ductwork system is impractical. In these situations, mobile or wall-mounted ductless split systems are an ideal option. 

Ductless air conditioners are not only convenient and efficient but also adaptable to specific operating conditions without unnecessary costs or construction complexities.

Advantages of Ductless Air Conditioners for Homes in Chicago and Illinois 

Ductless air conditioners (most often split and multi-split systems) are becoming an increasingly popular choice for residences and apartments, especially in buildings without central air conditioning. Their advantages are particularly noticeable in the climate of Chicago and most of Illinois.

1. Energy Efficiency in a Variable Climate. This leads to lower electricity bills and quick adaptability to changing weather conditions, which is especially beneficial in older homes where insulation is far from perfect. 

2. Ideal for Homes Without Central Air Conditioning. Ductwork installation can be expensive and complex. Ductless systems are easily installed in 1–2 days without structural interference. 

3. Zoned Comfort (Cooling and Heating). This offers individual temperature control in the desired room and the ability to install multiple indoor units with a single outdoor unit. 

4. Reverse Cycle (Heat Pump). This provides economical heating during mild seasons (efficient heating operation down to 5°F (-15°C) and below), allowing for reduced use of gas heating. 

5. Quiet Operation. Ductless systems are typically significantly quieter than central and window units, both indoors and outdoors, which is especially important in densely populated areas. 

6. Ease of Installation in Apartments and Townhouses. Townhouses, apartments, or condominiums often have limited options for ductwork or bulky system installations. Ductless air conditioners require minimal space and easily fit even in areas with limited installation possibilities. 

Thanks to their ability to provide heating in winter, ductless systems are a year-round investment in comfort and energy efficiency.

What Are the Key Aspects of Ductless Air Conditioner Installation? 

A properly installed air conditioning system guarantees reliable, quiet, and energy-efficient operation for many years. This is especially true when ductwork installation is impossible or impractical. 

Installing a ductless air conditioner requires precision and professionalism. It involves several stages: 

1. Planning and Equipment Selection. Before installation, a specialist inspects the premises to determine: 

• the number of rooms needing air conditioning; 
• the optimal placement of the indoor and outdoor units; 
• the effective equipment capacity; 
• possible obstacles (limited access, wall thickness, interior design); 
• the length of the piping and potential height differences between the units. 

2. Indoor Unit Installation. At this stage, the mounting location on the wall is chosen (usually 6–8 feet from the floor):

• a hole about 2.5–3 inches in diameter is drilled in the wall for pipes, drainage, and electrical cables; 
• the indoor unit is secured to a mounting plate, which is fixed to the wall; depending on the model, the possibility of installing the indoor unit on the ceiling or in a recess is considered. 

3. Outdoor Unit Installation. The outdoor unit is installed on a concrete pad or wall bracket outside the building, or on the roof:

• it should be a well-ventilated location with easy access for maintenance; 
• it's important to ensure stability and protection from snow, rain, and direct ice impact.

4. Connecting the Units. A sealed connection of components is made: 

• suction and liquid lines of copper tubing connect the indoor and outdoor unit; 
• a drainage line is run; 
• signal and power cables are routed; 
• after assembly, the system is evacuated to remove moisture and air. 

5. Commissioning and Testing. After all work is completed, the specialist checks: 

• refrigerant pressure and temperature; 
• compressor operation; 
• correct control from the remote or thermostat; 
• condensate drainage. 

To maintain aesthetics, pipelines and cables (mostly on the exterior) are covered with decorative plastic channels. In new homes with major renovations, hidden conduit can be used during ductless AC installation.
