Is there a room in your home that’s always too hot in the summer or freezing in the winter? That might be a sign your HVAC system isn’t reaching every space effectively. The solution could be simpler than you think: duct extension.

At Tri-Star Heating and Cooling, we specialize in helping families like yours enjoy even, comfortable temperatures throughout the house, without major remodeling or sky-high utility bills. Our duct extension services are perfect for homes with recent additions, converted attics or basements, or underserved rooms that just never feel quite right.

Let’s walk through how duct extension works and why it might be just what your home needs.

What Is Duct Extension—and When Do You Need It?

Duct extension means adding new sections of ductwork to your existing heating and cooling system. It’s a smart way to bring air conditioning or heat into areas that weren’t originally connected to your HVAC setup.

You might benefit from duct extension if:

• You’ve added on to your home—like a sunroom, garage, or extra bedroom
• You’ve converted a basement or attic into a living space
• Some rooms always feel hotter or colder than others
• You want to improve airflow and comfort without installing a new system

Extending your ducts can help you make the most of your current HVAC system, keeping your home balanced and comfortable all year long.

Why Duct Extension Is a Smart Choice

Instead of investing in a whole new HVAC unit or using portable heaters and window ACs, duct extension offers a more affordable, long-term fix.

Done properly, it can:

• Improve air circulation and balance in your home
• Help your HVAC system run more efficiently
• Lower your energy bills by preventing overuse
• Boost your comfort in hard-to-reach areas

A properly extended duct system doesn’t just move more air—it moves it more efficiently, helping your home feel better without raising your bills.

How We Extend Ductwork the Right Way

At Tri-Star, we don’t believe in guesswork. Our trained technicians take the time to inspect your current HVAC system and layout.

We check for things like:

• System capacity (Can your system handle the extra space?)
• Airflow balance (Will the new ducts improve or hurt airflow?)
• Proper insulation and sealing

Once we have a plan in place, we custom-fit the new ductwork using high-quality materials and craftsmanship. We always aim to make the installation clean, efficient, and minimally disruptive to your home.

Frequently Asked Questions About Duct Extension

Can I extend the ducts myself?
It’s not recommended. Ductwork requires careful sizing and placement to work properly. A DIY job could hurt your HVAC system’s performance or lead to costly problems down the road.

Will extending ducts affect my HVAC system?
If done right, no. But it’s important to make sure your system is powerful enough to handle the added space. That’s why we start with a full evaluation before any work begins.

Is duct extension cheaper than installing a new unit?
In most cases, yes. If your current system is in good shape, extending the ducts is much more cost-effective than upgrading to a larger HVAC system or installing separate units.

How long does duct extension take?
Most jobs can be completed in a day or two, depending on the size and complexity of the work. We’ll give you a clear timeline before we begin.
