Yes, replacing old ductwork can significantly improve your home’s energy efficiency. Over time, ducts can develop leaks, cracks, or become disconnected, causing conditioned air to escape before it reaches your living spaces. This forces your HVAC system to work harder, leading to higher energy bills and reduced performance. New ductwork is designed to provide airtight seals and proper insulation, ensuring air flows efficiently throughout your home. At Cottrell Plumbing, Heating & Air, we design modern duct systems that optimize airflow, reduce energy waste, and improve indoor comfort. Upgrading also allows us to correct design flaws that may exist in older systems, such as improper sizing or poor layout. These improvements not only lower utility costs but also extend the lifespan of your HVAC equipment. Homeowners often notice immediate improvements in comfort and savings after installing new, energy-efficient ductwork.

Absolutely. Damaged or leaky ductwork can allow dust, pollen, mold spores, and other contaminants to enter your home’s airflow, reducing indoor air quality and triggering allergies or respiratory issues. Repairing or replacing damaged sections helps seal the system and prevent pollutants from circulating. Additionally, well-maintained ducts distribute air more efficiently, improving ventilation and humidity control. At Cottrell Plumbing, Heating & Air, we go beyond basic repairs — we inspect for signs of dust buildup, mold growth, or pest intrusion and recommend solutions such as air purification systems or duct cleaning if necessary. Improved ductwork also supports better filtration performance from your HVAC system, ensuring cleaner, healthier air in your home. Regular maintenance combined with proper sealing and insulation can dramatically improve indoor air quality, creating a safer and more comfortable environment for your family year-round.

It’s recommended to have your residential ductwork inspected at least once every two to three years. However, homes with pets, allergies, or frequent HVAC use may benefit from annual inspections. Regular maintenance helps identify leaks, blockages, insulation issues, or signs of wear before they become major problems. At Cottrell Plumbing, Heating & Air, our technicians perform comprehensive ductwork inspections, checking for air leaks, loose connections, and dust buildup that could impact system efficiency and air quality. We also measure airflow and verify that your ducts are properly balanced for optimal performance. Routine service not only extends the life of your HVAC system but also helps maintain consistent indoor comfort and lower energy costs. If you’ve recently renovated your home or installed a new HVAC unit, scheduling an inspection is especially important to ensure your duct system is properly sized and configured for peak efficiency.
