Your ductwork is just as important as your furnace or air conditioner. Leaky ducts waste energy, create hot and cold spots, and make your HVAC system work harder than it needs to. Most homes lose 20 to 30 percent of their heated or cooled air through duct leaks, and poor duct design causes uneven temperatures that no amount of thermostat adjustment can fix. We install new ductwork for additions and whole-home systems, and we seal existing ducts to stop air loss. Properly designed and sealed ductwork delivers air where it's needed, reduces energy waste, and makes your home more comfortable.

We handle all types of ductwork projects, from simple repairs to complete system redesigns. Whether you're adding HVAC to a new space, replacing old ducts that are falling apart, or fixing a system that's never heated or cooled evenly, we design and install ductwork that matches your system's capacity and your home's layout. That includes sizing ducts for proper airflow, routing runs efficiently, installing dampers for zone control, and sealing all joints to prevent leaks. We also inspect existing ductwork and seal leaks that are costing you money every month.
