Signs Your Ductwork Needs Repair

Uneven temperatures, weak airflow and rising energy bills often trace back to your ductwork.


Call for an inspection when you notice:

  • Hot and cold spots between rooms
  • Weak airflow from your vents
  • Energy bills climbing each season
  • Excess dust or declining indoor air quality
  • Whistling or rattling noises from vents
  • A system running longer to reach the set temperature
  • Visible duct damage or loose connections

Leaking or damaged ducts force your HVAC system to run longer. Longer run times raise your bills and shorten equipment life.

Air Duct Replacement and New Installation

Copying an old duct layout repeats the old problems. We start every installation with a heat load calculation. The calculation accounts for your home's square footage, insulation, window ratings and sun exposure. Your system and ductwork get sized to your home from the start.

1. Custom duct design. We calculate duct sizes and layout with design software so air reaches every room evenly.

2. Professional installation. Our technicians install your ductwork with quality materials and follow all safety and building codes.

3. Duct leak testing. We pressurize your duct system and measure leakage. We document and fix leakage above 5%. You stop paying to cool the space under your house.

4. Airflow balancing. We test the finished system room by room. Dampered takeoffs let us adjust airflow at each supply line, so a small bathroom does not get 100 CFM while your main bedroom runs hot.

Why Duct Sizing Matters in Huntsville Homes

Duct and system sizing controls both temperature and humidity. An oversized system cools quickly and shuts off before removing moisture from the air. Your thermostat reads the right number and your home still feels sticky. Huntsville summers are humid, so sizing errors show up fast.


Our heat load calculation prevents the problem before installation begins.

Keep Your System Protected With the Comfort Club

Our annual maintenance plan starts at $149 per year. The plan includes seasonal tune-ups, coil cleaning, filter checks and furnace safety diagnostics. Routine maintenance catches small problems before they turn into expensive repairs.

Air Duct Repair and Replacement FAQs

Get answers to your most pressing questions about air duct repair and replacement. Our team at Central Heating & Air is here to help you make informed decisions for your HVAC needs.

  • How do I know if I need duct repair or a full replacement?

    Repair works when damage is limited to a few sections or connections. Replacement makes sense when ducts are the wrong size for your home or damage runs through most of the system. We compare equipment age, repair cost and efficiency gain with you before recommending a path.

  • How much air do leaky ducts lose?

    According to ENERGY STAR, homes can lose 20 to 30 percent of air due to leaks and poor connections. We pressurize ducts to measure and fix leaks exceeding 5%.

  • Why does duct sizing matter?

    Improperly sized ducts can disrupt temperature and humidity balance. Oversized ducts cool too quickly, leaving humidity in the air. Our heat load calculation ensures proper sizing.

  • What does the 10/10/10 Warranty cover?

    Our 10/10/10 Warranty includes 10 years of labor and lifetime coverage on gas furnace heat exchangers, providing peace of mind for a full decade.

  • What areas do you serve for duct repair?
