man fixing home's ductwork
March 28, 2023

While your HVAC system is one of the most important components of your California home, your ductwork—though often overlooked—is equally important. Improper ventilation and duct design can lead to health and comfort issues, like trouble breathing or poor air distribution. Problems with your ductwork could be caused by:

  • Improper duct sizing

  • Unsealed ducts

  • Poor ductwork insulation

  • Bad ductwork design

Sometimes, your ductwork may just need to be cleaned or repaired, while other times the only solution is ductwork replacement. At Greiner Heating, Air, & Solar, we can help you determine exactly what’s best for your Davis home, whether it be a complete overhaul or a simple ductwork modification. 

Signs of Bad Ductwork

Your ductwork is mostly hidden throughout your walls, making it difficult to determine if there are any issues. You can check for dents, leaks, and condensation where your ductwork is exposed, but here are some other common signs to look out for:

Increased Energy Costs

While an increase in your utility bills can be caused by a variety of factors, your ductwork can also contribute to high energy costs. Bad ductwork installation or leaks can cause a loss of 20-30% of all the airflow through your ductwork.

Odd Smells

Dust accumulation, mold growth, or pest infestations (like insects or rodents) being in your ductwork can all cause musty or strange smells when your HVAC is running. These smells can increase allergy symptoms and be a sign of poor indoor air quality with several health effects.

Increased Dust

If you have noticed more dust on the surfaces throughout your California home, it could be coming from your ductwork. More dust means an increase in allergies and other signs of poor indoor quality. 

Poor Performance

The efficiency of your HVAC system will only go so far with poor ductwork installation. Inconsistent room temperatures or decreased airflow—especially without any recent renovations—can mean your ductwork isn’t performing as it should.
