Why Is My House So Dusty?

Duct work is an important part of your home’s HVAC system. Unfortunately, out of sight- out of mind. We tend to forget about it. Duct work problems can cause high energy bills and issues with heating and cooling.

Below are five main issues that duct work might have and how to handle them.


If your ducts aren’t properly airtight, you’ll lose air to the surrounding spaces. When this occurs there is energy loss, because you’ll have to turn up your furnace to get a comfortable temperature. Your home will also have uncomfortable rooms where there’s not enough air to heat/cool them.

Duct, Allergen & Germ Buildup

Ducts can circulate dust throughout your entire home. This results in poor indoor air quality and can get your family sick.

You need to have your ducts cleaned every few years. The frequency will depend on whether you have allergies, pets, or live in a dusty area. We offer complimentary duct fogging with an $89 tune up.

Poor Sizing

Air flow circulation depends on duct work sizing. Even with dampers, ducts must be correctly sized for the amount of air needed to condition a space.

If you notice some rooms consistently hot in the summer and cold in the winter, call us to assess your duct sizing. You might have to replace and re-balance portions of your duct work system.

Poor Layout

If you have duct runs that are too long, the pressure drops in the system will reduce the amount of air reaching the grilles. Similarly, if the duct work has too many elbows and branch take-offs, the losses will interfere with your airflow.

No Insulation (Or Not Enough)

Parts of your duct work might be routed through unheated spaces, such as your attic. Ideally, you want to avoid this situation, but it’s not always possible. Losses through these spaces can cost you hundreds on your energy bill each year.

Make sure your duct work is insulated and verify the condition of your existing insulation. You can add another layer of insulation to duct work in unheated spaces to save more energy.
