Ductwork Stoughton
Maximize your heating and cooling efficiency with professional ductwork services.





Air Duct Solutions
Reliable ductwork helps keep air flowing smoothly and maintains balanced indoor temperatures across every room. Even the most efficient heating or cooling system will struggle if your air ducts are leaky, undersized, or poorly designed. We evaluate your existing duct system, seal air leaks, and design custom sheet metal pathways to optimize your home's air delivery.
Southern Wisconsin weather brings high humidity during summer afternoons. When hot, humid air comes into contact with cool, uninsulated metal ducts in crawlspaces or attics, condensation forms. This moisture can damage plaster, ruin insulation, and lead to mold growth. We focus on proper duct insulation and sealing to prevent condensation and keep your indoor air dry and clean.
Leaky ducts are a major source of energy waste, causing your heating and cooling systems to work much harder than necessary. According to the U.S. Environmental Protection Agency, typical duct systems lose up to 20 percent of the air that moves through them due to leaks and poor connections. Sealing these gaps keeps conditioned air inside your living spaces, lowering your energy costs.
If you are planning an upgrade like a modern ac installation, matching your ducts to the blower capacity of your new unit is critical. Undersized ducts restrict airflow, which places extra stress on system components and can lead to coil freeze-ups. We design duct modifications that support your climate systems, ensuring quiet operation and even heating and cooling throughout your property.

Service Options
Ductwork Materials We Install
Rigid Sheet Metal Ducts
Galvanized steel ducts are durable, smooth, and resistant to mold growth. We custom-fit these pipes to provide the most reliable airflow pathway for your home.
Flexible Ductwork
Ideal for tight spaces and tricky turns, flexible ducts use a wire coil covered by durable plastic. Proper installation is key to prevent kinks that restrict airflow.
Fiberglass Duct Boards
These boards feature built-in thermal insulation and absorb sound, making them a great choice for quiet heating and cooling delivery in residential spaces.
Why Choose Us
Advantages of Proper Duct Sealing
Even Temperatures
Eliminating air leaks ensures that rooms furthest from your heating or cooling system receive the right amount of conditioned air.
Lower Monthly Bills
Sealing duct gaps stops warm or cool air from escaping into attics or crawlspaces, reducing the workload on your HVAC system and lowering utility costs.
Better Indoor Air Quality
Sealed ducts prevent dust, pollen, and attic insulation fibers from being pulled into the air stream and circulated throughout your home.
Pricing Guide
What Drives Ductwork Costs
Linear Footage
The scale of your duct system is the primary cost driver, with custom ductwork costs varying based on the size and complexity of your home's layout.
Access Difficulty
Ducts located in tight crawlspaces, low attics, or finished walls require more labor to repair, seal, or replace than easily accessible basement runs.
The Contractor You Choose
Hiring a licensed, insured, and bonded professional ensures that your system's static pressure is balanced correctly. APT Heating and Cooling employs NATE-certified technicians who test duct airflows to keep your systems running within manufacturer guidelines.
