Frequently asked questions
- Why is custom ductwork important for HVAC performance?
- Custom ductwork ensures that air is distributed efficiently throughout your home based on its unique design and your HVAC system’s capabilities. Unlike generic duct layouts, custom systems eliminate airflow bottlenecks, balance temperature more evenly across rooms, and minimize energy waste—delivering better comfort and lower utility bills.
- How do I know if I need custom ductwork?
- If you’re experiencing uneven temperatures, noisy vents, high energy bills, or limited airflow, your ductwork might be poorly designed or damaged. Custom ductwork can solve these problems by matching the duct layout to your home's structure and your HVAC system’s output, ensuring smoother, more efficient airflow.
- Can I upgrade my current ducts without replacing the whole HVAC system?
- Yes. In fact, upgrading your ductwork can significantly improve the performance of your current HVAC system. Replacing undersized, leaking, or improperly routed ducts with custom-fitted ones can improve airflow, reduce energy usage, and extend your HVAC system’s lifespan.
- What’s involved in designing custom ductwork?
- We start with a full assessment of your home’s layout, insulation, and HVAC equipment. Then, we design a duct system that’s properly sized and routed for efficient airflow, using high-quality materials and expert installation techniques. The result is quieter operation, balanced temperatures, and better overall performance.
- How long does custom ductwork installation take?
- The timeline depends on your home's size and complexity, but most custom ductwork projects take between one and three days.
