Fixing What You Don't See

Duct installation, repair, and airflow improvements for Maple Grove homes with uneven heating, cooling issues, or older systems that never worked right.

One room stays cold while another overheats, or your furnace runs constantly without raising the temperature. In many Maple Grove homes, the problem isn't the furnace or air conditioner but the ductwork that moves air through your house. HVAC-KING addresses common airflow and comfort issues in older homes by repairing leaking ducts, correcting improperly sized sections, and installing new ductwork when the existing system can't be fixed. Over two decades of experience working in local homes means understanding how split-levels, additions, and finished basements affect airflow.

Ductwork service includes sealing leaks with mastic and metal tape, replacing crushed or disconnected sections, and resizing ducts that restrict airflow to certain rooms. The work is often paired with furnace or air conditioner replacements but can be done independently if you're dealing with comfort problems that equipment can't solve. HVAC-KING provides straightforward recommendations based on what your system actually needs rather than upselling unnecessary upgrades.

If you're dealing with hot or cold spots in your Maple Grove home, contact HVAC-KING to schedule an airflow evaluation.

How Ductwork Repairs and Installations Work

The first step is inspecting your ductwork to identify leaks, disconnected sections, or improperly sized runs that limit airflow. HVAC-KING seals leaks using mastic sealant and metal-backed tape, replaces damaged sections with new sheet metal or flex duct, and adjusts dampers to balance airflow between rooms. If you're adding a new system or finishing a basement, new duct runs are installed to match your home's layout and heating or cooling load.

After the work is done, you'll notice more consistent temperatures throughout your home, less dust circulating from leaky joints, and improved system efficiency because conditioned air reaches the rooms it's meant to serve. Your furnace or air conditioner won't run as long to maintain setpoint.

Ductwork repairs typically take a few hours, while full installations can take one to two days depending on how much of the system needs replacement. HVAC-KING works in crawl spaces, attics, and basements to access existing ductwork. The service does not include insulation removal or structural modifications unless discussed in advance.

What People Ask About Ductwork

Most homeowners don't think about ductwork until they notice comfort problems, so questions usually focus on whether repairs are necessary and what results to expect.

How do I know if my ductwork is the problem?
If some rooms are consistently hotter or colder than others, or if your system runs constantly without improving comfort, leaking or improperly sized ductwork is often the cause. HVAC-KING inspects the system to confirm before recommending repairs.
What causes ducts to leak or fail?
Ducts leak at joints that were poorly sealed during installation, or flex duct gets crushed or disconnected in crawl spaces and attics. Older homes in Maple Grove often have undersized ducts that restrict airflow to additions or upper floors.
How long does ductwork repair take?
Sealing leaks and repairing disconnected sections usually takes a few hours, while replacing entire duct runs or adding new branches can take one to two days. The timeline depends on how much of the system needs work.
Will fixing my ductwork lower my heating and cooling bills?
Yes, sealing leaks and improving airflow reduces how long your furnace or air conditioner runs to maintain temperature. The exact savings depend on how much air was leaking and how inefficient the system was before repairs.
Can ductwork be installed in a finished basement?
Yes, but it requires careful planning to avoid tearing up walls or ceilings. HVAC-KING routes new ducts through existing chases, soffits, or dropped ceilings whenever possible to minimize disruption.

HVAC-KING has repaired and installed ductwork in Maple Grove homes for over 20 years, working in tight crawl spaces, vaulted ceilings, and older layouts that were never designed for central air. If you're dealing with uneven heating or cooling, call (763) 203-3075 to schedule an airflow evaluation.
