For flexible, energy-efficient heating and cooling in homes without traditional ductwork—or in spaces where conventional systems fall short—ductless mini-splits are a smart, high-performance solution. At A.H. Brenner Heating & Cooling, we specialize in ductless mini-split installation and replacement for homeowners in Sycamore, IL, and surrounding communities, with a focus on custom homes, high-efficiency retrofits, and room-specific comfort.
As a Mitsubishi Diamond Contractor, we bring advanced knowledge and factory-trained expertise to every ductless project. Whether you're upgrading an older mini-split system, building a home with limited ductwork, or looking to heat and cool specific areas like sunrooms, garages, basements, or in-law suites, we tailor your mini-split system for maximum comfort and efficiency.
A ductless mini-split system consists of one or more indoor air handling units (heads) connected to an outdoor heat pump or condenser. Each indoor unit operates independently, giving you zoned temperature control in specific rooms or areas.
We work closely with builders, architects, and homeowners during the planning and construction phase to design ductless systems that seamlessly integrate into the home.
Already have a ductless system but noticing decreased performance, outdated controls, or rising energy bills? We offer mini-split replacement services for aging or underperforming units.
Signs it's time to replace your ductless mini-split:
We'll inspect your current system, explain your options, and help you transition to a new Mitsubishi system with greater energy efficiency, quieter operation, and modern features.
Ductless mini-splits allow for fully customized climate control, ideal for families or households with varying comfort needs. You can heat or cool only the rooms you use—saving energy while improving comfort.
Mini-splits also help address common home challenges, such as:

A ductless mini-split is a heating and cooling system that does not require ductwork. It consists of an outdoor unit and one or more indoor air handlers that can be mounted on walls, ceilings, or floors. Each indoor unit operates independently, allowing for zoned temperature control in specific areas of your home.
Yes. Mini-splits are ideal for Sycamore homes with no existing ductwork, or for rooms that are difficult to heat or cool using traditional HVAC. They are also excellent for garages, basements, additions, and custom homes where flexibility and energy efficiency are a priority.
Absolutely. Modern mini-splits function as reversible heat pumps, meaning they provide both heating in the winter and cooling in the summer. Mitsubishi systems, in particular, are capable of delivering consistent performance even during freezing temperatures.
This depends on the model, but most systems support two to eight indoor units per outdoor condenser. Multi-zone systems allow you to condition multiple rooms or entire floors independently while using just one exterior component.
Yes. Mini-splits use inverter technology that adjusts output based on demand, which makes them much more energy-efficient than standard HVAC systems. You’ll likely see lower energy bills and improved comfort.
In many cases, yes. Energy-efficient ductless mini-split systems may qualify for rebates through state programs or utility providers. We can help you determine eligibility and guide you through the application process.
Most single-zone systems can be installed in one day. Multi-zone systems may take longer, depending on the number of indoor units and the complexity of the layout. We’ll provide a timeline during your consultation.
Not at all. Modern mini-splits come in sleek, compact designs that can be mounted high on the wall, flush with the ceiling, or even recessed. Mitsubishi offers multiple style options that blend in with a variety of interior designs.
Yes. Many systems—especially those from Mitsubishi—can be connected to Wi-Fi and controlled using apps like Kumo Cloud. You can adjust temperature settings, create schedules, and monitor energy use remotely.
With proper maintenance, a high-quality ductless mini-split system can last 12 to 15 years or longer. Regular cleaning and seasonal checkups will help extend its service life.
Yes. Ductless systems operate independently, making them ideal for rooms not connected to central HVAC. They won’t interfere with your existing system and can even reduce the load on it.
We do. If your current mini-split is underperforming or outdated, we can help you select a modern replacement with better efficiency, quieter operation, and improved controls.
