Signs your ductwork needs attention

Spencer’s licensed HVAC technicians have been repairing and installing ductwork for North Shore homeowners for over 45 years. If you notice any of these warning signs, call us for a free estimate.

  • Uneven temperatures between roomsWhat we check

    If some rooms in your home are significantly warmer or cooler than others despite your thermostat being set correctly, leaky or poorly designed ductwork is likely the cause. Gaps and disconnections allow conditioned air to escape before reaching distant rooms.

    We follow the runs to the rooms that suffer and look for disconnections, leaks and undersized branches.

    • Airflow at the registers
    • Joints and connections
    • Run size and length
  • Unusually high energy billsWhat we check

    When your heating and cooling costs climb without a change in usage, leaky ductwork is one of the most common culprits. Air lost through duct leaks is energy you pay for, and sealing those leaks can reduce it.

    We look at ducts in unheated spaces first, where leaks and missing insulation cost the most.

    • Ducts in the attic, basement or crawl space
    • Insulation on exposed runs
    • Sealed or taped joints
  • Excessive dust in your homeWhat we check

    Leaky return ducts pull unconditioned, dusty air from attics, basements, and crawl spaces into your HVAC system and distribute it throughout your home. If dusting feels like a losing battle, your ductwork may be the source of the problem.

    We check the return side, where a leak draws in dust before the filter.

    • Return duct connections
    • Filter fit
    • Panned joist returns
  • Noisy ductwork when the system runsWhat we check

    Rattling, popping, banging, or whistling sounds from your ducts indicate loose connections, undersized runs, or pressure imbalances. These noises signal structural issues that reduce efficiency and can worsen over time if not addressed.

    We find where the noise starts and whether it is a loose hanger, a joint, or ducts too small for the airflow.

    • Hangers and supports
    • Plenum and trunk joints
    • Duct size against airflow
  • Visible duct damage or disconnectionsWhat we check

    If you can see crushed, torn, disconnected, or sagging ductwork in your attic, basement, or crawl space, conditioned air is escaping directly into unconditioned space. This visible damage requires prompt professional repair to restore system efficiency.

    We check whether the damaged section can be reconnected and sealed or should be replaced.

    • Crushed or torn flex duct
    • Separated joints
    • Sagging runs

What to expect from your ductwork service

  1. Contact us

    Tell us which rooms are uncomfortable or what you have seen, and we set up a visit.

  2. In-home assessment

    We inspect the ducts we can reach, check airflow at the registers, and look at the joints and insulation.

  3. Custom recommendation

    We explain whether sealing, a repair or new ductwork fits and the price before you approve any work.

  4. Expert installation

    We seal, reconnect, insulate or install the ductwork.

  5. Airflow checked

    We run the system and check airflow at the registers before we leave.

What changes the work and the price?

The exact price comes after we see the ducts. These are the factors that most often change the work.

Call 978-293-5770Book online

  • Access

    Ducts in an open basement are quicker to reach than ducts in a tight attic or behind finished walls.

  • Condition

    Sound ducts can be sealed; crushed or corroded sections have to be replaced.

  • How much is involved

    One disconnected run and a whole trunk line are very different jobs.

  • Insulation

    Ducts in unconditioned space may need insulation as part of the work.

Our work is backed by a lifetime workmanship warranty for the typical lifespan of the installation. Terms apply.

The right ductwork fix depends on what we find

Condition, location and the system's airflow decide which approach makes sense.

  • Seal and reconnect

    Close leaking joints and reattach runs that have come apart, when the ducts themselves are sound.

    • Leaking joints sealed
    • Disconnected runs reattached

  • Insulate exposed runs

    Add or repair insulation on ducts in an attic, basement or crawl space.

    • Less heat lost or gained
    • Less condensation on cooling ducts

  • Replace or add ductwork

    Install new runs, sized to the system, for damaged sections, additions or a new forced-air system.

    • Sized to the equipment
    • Airflow checked at each register

Frequently asked questions

Call 978-293-5770

  • How do I know if my ducts have problems?

    Common signs include uneven room temperatures, high energy bills, excessive dust, and noisy operation. We inspect the ducts we can reach, check airflow at the registers, and show you what we found with the repair options.

  • How much does duct repair vs replacement cost?

    Sealing and reconnecting sound ducts costs less than replacing damaged runs; access, condition and insulation change the price too. Estimates for installations and replacements are free. You get the exact price before any work begins.

  • What are the benefits of duct sealing?

    Sealing leaky joints keeps more of the heated or cooled air in the ducts on its way to the rooms. That can lower energy use, even out room temperatures, and cut the dust drawn into the return ducts.

  • How long does ductwork installation take?

    It depends on the size of the job. Sealing and repairing ducts we can reach can usually be done in one visit; new ductwork for a whole house takes longer, and we give you the schedule with the price.

  • Can leaky ducts be repaired, or do they need to be replaced?

    Most leaks are at joints and connections, and those can be sealed. Ducts that are crushed, torn or corroded are replaced. We show you what we found before recommending either.

  • Should ductwork in the attic or basement be insulated?

    Ducts that run through an unheated attic, garage or crawl space should be insulated, so the air keeps its heat or cooling on the way to the rooms. Ducts inside the heated part of the house usually do not need it.
