Did You Know?

Clogged Dryer Vents Are the #1 Cause of House Fires

Dryer vents should be checked at least once a year — more often if you do a lot of laundry. Dryers can’t run efficiently when they are clogged and take longer to dry your clothes.

A $99 annual check up can save wasted energy and potentially prevent a house fire.

Clogged Dryer Vent Got You Down?

GST Air Duct Cleaning has skilled technicians that can remove the lint buildup in your vent so your clothes dry faster and with less energy.

Businesses Need Clean Air Too!

Dust happens. In a business, there is even more of it. You’re closer to busy streets and everyone that comes in tracks in dirt that goes airborne and eventually ends up in your air ducts.

There’s nothing worse than blowing dirty, dusty air all over your precious customers and employees. That’s why businesses large and small trust GST Air Duct Cleaning to keep their air ducts pristine.

New home construction needs air ducts cleaned

Common Myth:

Air Ducts Don’t Need to Be Cleaned

If your house is new and the contractor had them professionally cleaned before you moved in, you’re fine. If not, your ducts are likely full of sheetrock dust, sawdust, nails, and other debris from construction.

If your house is older, it’s a good idea to get them checked. Consider pet hair, your proximity to road dust, family members with asthma or allergies, how often you mop or vacuum, how often you replace your furnace filters, whether rodents can get into your ducts… well you get the idea!

If you haven’t had an air duct cleaning done in the last 5 years, call us for an inspection. We’ll show you what we see and if your ducts don’t need to be cleaned yet, we’ll tell you so.

Frequently Asked Questions

How do I know if my air ducts need cleaning?

We’ll do an analysis and if they don’t need it, we’ll show you and give you our best estimate as to how long you can wait.

How often should I get my air ducts cleaned?

Once every five years is sufficient for most homes and businesses. If you have asthma, allergies or other respiratory issues, more often might help. It’s a good idea after construction as a lot of sawdust, sheetrock dust, and other debris end up in your air ducts.

How often should I get my dryer vent cleaned?

At least once a year — twice if you do a lot of laundry. If your dryer vent is clogged, it will take longer to dry your clothes which wastes energy. Worse, it could cause a house fire.
