Ductwork Repair

Do you hear strange new sounds coming from your vents? Are you not getting the same airflow you used to? You may have broken or damaged ductwork. Depending on the issue and its location in your home, air duct repair can be simple or require a full replacement. 

Hiring somebody to repair ductwork in your home can save you hundreds of dollars per year in energy costs. Well-maintained ductwork helps keep your home warm in the cold Milwaukee winters and cool during the hot summer months.

 In this article, we’ll explore the signs of bad ductwork and what Milwaukee families can expect when they choose Over The Moon for air duct servicing.

8 Signs You May Have Bad Ductwork

Signs that you have bad or damaged ductwork include:

1. Strange sounds

You may notice a whistling or rattling noise when your A/C or heat kicks in. This is due to pressurized air being forced through cracks or holes or rattling loose pieces of metal.

2. Increased energy bills

If your HVAC system has to work harder and longer to push air through your home, you may see an uptick in energy costs. 

3. Dusty house

Cracks or openings in your ductwork let dust and debris enter the system. The dust is then blown through your home, especially when you turn your air conditioner on. If your home is dustier than normal or you see debris around the vents, you may have a duct breach.

4. Poor airflow from vents

Damaged ducts allow air to escape through cracks and holes, lowering the overall air pressure and reducing flow from your home’s vents.

5. Hot or cold air leaking into walls, attic, or crawlspace

If you notice abnormally warm or cold spots in your house or you feel airflow where it shouldn’t be, you may need somebody to repair your ductwork.

6. Pests are getting in

A hole in your ductwork allows pests like mice to get in and build nests. Their waste and nesting material can cause your family serious health issues, including asthma and allergies. If you or your family is experiencing new respiratory problems, bad ductwork could be the cause.

7. Mold contamination

Moist, warm areas are the perfect conditions for mold to grow. Inhaling dangerous mold spores can cause health issues like allergic reactions, worsening of asthma, sore throats, sneezing, and inflammation of the eyes, skin, nose, throat, and lungs. Replacing contaminated ducts helps prevent these issues.

8. Strange odors 

If you smell a smoky, musty, or foul odor from your vents, it may be a sign of a duct problem. An HVAC professional can inspect the ducts to determine the source of the smell.

Besides duct replacement, the most common ductwork repair solution for these issues is sealing holes or replacing ducts in the problem areas. This restores proper airflow and closes gaps where grime or pests can get in. A professional cleaning with antibacterial, odor-fighting compounds ensures your home’s air is clean.

How Long Does It Take To Redo Ductwork?

On average, completing a ductwork project takes one to four days. Each home is unique in how the HVAC systems are set up and the issues they may be experiencing. Other factors that may extend the timeline include:

  • The size of the duct network
  • The complexity of the system’s design
  • The ease of accessibility to the ducts
  • Whether permits are needed to do the job
  • Whether you’re having ducts repaired or upgraded
  • Pest infestations or other issues to take care of before starting work

Each home has its challenges. Over the Moon does a full assessment to let you know what to expect before we start any air duct repair project.

What’s the Life Expectancy of Ductwork?

The typical life expectancy of a home’s ductwork is 10 to 15 years. However, you may get up to 25 years out of your home’s system if you keep your ducts well-maintained, get them professionally cleaned regularly, and replace broken pieces as necessary.
