At A.H. Brenner Heating & Cooling, we bring true craftsmanship to every HVAC system we design and install—because your home deserves more than an off-the-shelf solution. Our specialty lies in working with custom new construction projects and remodels throughout Sycamore, IL, and nearby communities.
We do not work on cookie-cutter tract homes or bulk builds. Instead, we partner with homeowners and builders who prioritize comfort, performance, and thoughtful design. When you're building a custom home, your HVAC system should be just as intentional as your architecture, finishes, and layout.
Custom homes are not standard—and neither are their HVAC needs. When a builder installs the same HVAC layout across dozens of homes, it rarely accounts for the unique demands of your floor plan, ceiling height, window exposure, or personal preferences.
We offer a comprehensive suite of HVAC services for new custom homes, designed to deliver superior comfort and efficiency:
A thoughtful remodel should improve your home's livability and efficiency—not just its looks. We help homeowners and contractors design HVAC upgrades that match the quality of their renovation work.
Our remodel-focused HVAC services include:
We respect your vision and provide HVAC guidance that complements your design plans—not competes with them.
During the new build process, we coordinate directly with your construction timeline to ensure seamless HVAC system installation. From rough-in through finish, we stay involved and communicative, adjusting plans as needed while preserving your schedule.
We prefer to get involved during the architectural or framing phase. This allows us to:
By integrating early, we ensure the final system is quiet, effective, and beautifully integrated—not an afterthought.
One of the biggest advantages of a custom HVAC system is zoning. With properly designed zones, each part of the home maintains its own ideal temperature without overcooling or overheating other areas.
Zoning is especially beneficial for:
We specialize in designing zoned ductwork, smart thermostat groupings, and multi-zone mini-split configurations that give you complete control of your environment—room by room.
We believe HVAC is as much about the process as it is the result. That's why we operate with clear communication, construction-friendly flexibility, and a commitment to job site professionalism. Builders, designers, and project managers rely on us because:
And just like our clients, we care about the details. We measure twice, bend ductwork precisely, and make decisions that preserve both performance and aesthetics.
We work with trusted manufacturers that align with our high standards for quality, performance, and longevity.
Together, these products give our clients comfort they can feel—and confidence that their system will last for years to come.
Learn MoreMany custom homes include finished or semi-finished garages, workshops, or hobby spaces. These areas often fall outside the main HVAC system but still require heating or cooling.

Custom homes often feature unique layouts, vaulted ceilings, specialty rooms, and higher expectations for comfort and control. HVAC systems for these homes must be carefully designed with zoning, airflow, equipment sizing, and placement in mind. Unlike cookie-cutter builds, each system is crafted to fit the home—not the other way around.
HVAC planning should begin as early as possible, ideally during the architectural design or framing phase. Early planning allows for better ductwork routing, correct equipment sizing, and integration with other systems like electrical, plumbing, cabinetry, and trim. The earlier we’re involved, the better the end result.
