Signs Your Ducts Need Repair

Signs Your Ducts Need Repair

Common indicators that your ductwork needs professional attention

High Energy Bills

Leaky ducts waste 20-30% of conditioned air, forcing your HVAC system to work harder and driving up energy costs significantly.

Uneven Temperatures

Some rooms too hot or cold? Leaky or disconnected ducts prevent proper airflow to certain areas of your home.

Poor Airflow

Weak airflow from vents or rooms that won't heat/cool properly indicate duct damage or disconnection.

Excessive Dust & Odors

Leaky ducts pull in dust from attics and crawl spaces, while moisture causes mold and musty odors circulating through your home.

Professional Repair

Our experienced technicians seal leaks with professional-grade mastic and metal tape, reconnect disconnected sections, replace damaged ducts, and add insulation where needed.

4

Testing & Verification

After repairs, we test airflow at each vent, verify temperature balance throughout your home, and ensure your HVAC system is operating efficiently.

Benefits of Professional Duct Repair

Properly sealed ducts reduce energy waste by 20-30%, saving the average homeowner $200-500 per year. Most duct repairs pay for themselves within 2-3 years through energy savings alone. Properly sealed ductwork ensures consistent temperatures throughout your home with no more hot and cold spots.

Sealed ducts prevent dust, allergens, and pollutants from entering your air supply, significantly improving indoor air quality for healthier living. When ducts leak, your HVAC system works harder to maintain temperature. Proper ductwork reduces strain on your equipment, extending its lifespan by years.

Our Duct Repair Services

Duct sealing: Professional sealing of leaks, gaps, and poor connections using mastic sealant and metal tape (not duct tape). Duct insulation: Add or replace duct insulation to prevent energy loss and condensation, essential for ducts in unconditioned spaces like attics and crawl spaces.

Duct replacement: Replace damaged, crushed, or deteriorated duct sections with properly sized ductwork for optimal airflow and efficiency. We repair all types of residential and commercial ductwork including sheet metal ducts, flex ducts, fiberglass duct board, and insulated ducts.
