Question: Why are the bags on the top of the furnace truck floppy?

Furnace cleaning trucks have a very distinct look and sound. When one is operating, you can hear it from a block away. When you see it there are normally several bags sticking out of the top of the truck. Have you ever wondered what those bags are for? 

Generally, people assume that the bags on the top of the furnace truck is the vacuum. When the bags are sticking straight up it must mean that the cleaning is underway, right?

The bags are actually an exhaust dust filter for the vacuum. Think of the little dust filters that you can buy for a shop vac that clip on the exhaust air port to prevent dust from filling the room. The bags are like those, but on a much larger scale.

The vacuum that sucks all the dirt out of your furnace system is actually located inside the truck. It’s very obvious when the vacuum is on and the cleaning is taking place – because you can’t hear anything else! The vacuum makes a very loud humming noise when operating, and as long as the sound is blasting, the vacuum is doing its job (and so are our technicians). 

If the bags aren’t sticking up straight, am I getting as good of a furnace cleaning?

Yes. Another assumption people have about the bags on the top of the furnace truck is that if they aren’t sticking up straight, the cleaning isn’t as good. But this is not the case. 

The bags filter out dust and debris from many houses, and every couple of months we have to clean them out because as you can imagine, they get filthy. The dirtier the bags are the more the airflow is restricted. This is because less air can get through the build up of dust, causing the bags to stick up in the air. 

So when you see bags that look like this:

…you know that a truck with recently cleaned bags is servicing your furnace system!

We proudly maintain our trucks at peak performance level, so whether the bags are floppy or sticking straight up in the air, you can trust that your furnace is getting the best cleaning possible.

What Our Customers Have To Say

This company knows their stuff, provides great customer service and excellent work. I’m totally happy with how the two very friendly annd knowledgeable associates cleaned my furnace, vents, dryer vent and AC coil. I will certainly book my next appointment with them.

- Mark

The technicians were efficient and very friendly. They explained what they how and what they were doing. The only thing was there was some sort of residue left on the concrete from their truck all the way to our front door that was not there before they arrived. (Dark stains on our driveway, walkway and front steps leading into the house).

- Maureen Miyagishima

I had an excellent experience with Alberta Furnace Cleaning. They promptly arrived on the first working day of the year, despite the cold weather. Their team provided detailed explanations regarding the service performed and offered helpful tips for maintaining my units. I am confident that I will book with them again in the next few years.

- Ramir L

The men who did the work were extremely friendly and professional. They were sure to introduce themselves to each of us properly. They explained everything they were doing and even showed us before and after pictures. They were very respectful of our home and used boots covers each time even when going back and forth from outside to in. They cleaned and wiped up their work areas before they left, which was very appreciated. We would hire them again, without hesitation.

- Melanie Collins

Alberta Furnace crews are professional and thorough from appointment to home service. I had my furnace serviced by someone else before and I can say that Alberta Furnace is far better. They protect the corners, walls and floors of the house and leave no marks behind. Their equipments are state-of-the-art. The best in what they do! Price is fair as well.

- Antonio Jr Reyes

A big shout out to Andrew and Aaron from Alberta Furnace Cleaning. My husband and I had recently renovated our home and were noticing a fine dust on everything that I couldn’t keep up with. Andrew and Aaron came in and cleaned the furnace, air conditioning unit and all the duct work. It was shocking to see what the found - construction debris, dog toys, tennis balls etc. They definitely have the equipment to thoroughly clean the mechanical and duct work. Both workers used care in removing vent covers, and cleaned all surfaces, properly replacing the grills when done. They were on time, efficient, polite and respectful of ourselves and our home. I could not be happier.
