Rusted out vent

Got Rusted Out Vents?

Here’s something that we frequently see when cleaning air ducts in older buildings.

This heating vent is located in a store on the Danforth, near the front door. It was totally rusted out to the point where almost no air was coming out of the vent. There was a gaping hole in the pipe underneath that was serving it.

If you have vents like this that are in need of repair, call us at City Duct Cleaning for a free estimate.

Another common thing we see while visiting older homes has to do with the return air vent right near the front door… the metal inside is often rotted out because over the years shoes and wet boots have been placed on the grill, causing the metal to rust out over time.

We can fix this for you, and this will help to make your HVAC system much more energy efficient. Repairing rusted out duct connector pipes and the metal boots will also make your home much more comfortable. And when you happen to look in, the metal will be shiny and new again!

After you have replaced any rusted ductwork in your home, you may want to consider sealing the system as needed. Sealing your home’s ductwork saves money, energy and your health. Find out why and how in this short video.

Magnehelic Gauge 1

The Technical Side To Cleaning A Dryer Vent

A magnehelic pressure gauge is a device, similar to a manometer, that is used to measure positive, negative, and differential pressures.

Just as a magnehelic gauge can give your HVAC technician a wealth of information about the operation of your furnace and duct system, it can also provide your duct cleaning technician with valuable information about your dryer exhaust vent too.

The magnehelic gauge can be used to quantify how blocked (or inefficient) a dryer is operating prior to cleaning the dryer vent. After cleaning, the gauge will tell you exactly how much more efficiently the dryer is venting. Technically speaking, dryer manufacturers say to have the dryer vent cleaned if the back pressure readings are greater than 0.6 – 0.75 inches of water column (wci), as indicated on the gauge itself.

The magnehelic gauge measures duct static pressure, which is the pressure the blower produces in the exhaust conduit. In this industry, back pressure is a result of one or more of these conditions: long duct runs, excessive elbows, squished transition hoses, lint buildup, bird nests, rodent nests, and termination hoods that are blocked or feature an inefficient design.

As you can see, cleaning a dryer exhaust duct can be narrowed down to a pretty exact science. Contact City Duct Cleaning today to schedule your dryer exhaust vent cleaning/inspection.

Dog and cat urinated in my air duct

My Animals Urinated in My Duct System Again! What Can I Do?

Pet Urine is difficult to locate in any home, even though it is very easy to smell. Pet urine can be removed out of your duct work. To determine where your pet has urinated, provide yourself with a UV black light. Make sure you turn all the lights off on that floor, so that you can be sure to see the glow.

Once you detect the area(s) where the pet has urinated, you must clean that area in its entirety. Most times animals will go to the bathroom on carpet or hardwood floors, which can be located close to your duct system. Once an animal has urinated in one spot then it is very instinctive that they keep re-soiling that specific area.

To remove the odor, it is highly NOT-RECOMMENDED to use any products that are ammonia based. As you know, if you have this problem, most urine has ammonia in it, which does not effectively clean the soiled area, and will keep the animal still interested to keep re-soiling this spot. We do recommend the use of baking soda with white vinegar. Please always do a test spot first to ensure that it does not create more damage, by discoloring your carpets or hardwood floors. Make sure that these products do not enter your heating and cooling system. If any of the products do enter the duct system, you should open all the windows and doors and call us.

Once the surrounding areas around the vents are cleaned, you will need to hire a professional duct cleaner. Dust, debris, crevices, or cracks can hold in the pet urine odor. Once your system is running it will distribute this awful smell throughout the home. At City Duct Cleaning we have the proper chemicals that can remove the urine smell from inside the ductwork, without contaminating the rest of your system.

 We have a long-time customer who had a kitten that took a liking to urinating directly over one particular air vent in her home.

The heat from the furnace would dry it out and spread the stink throughout the entire floor that vent was serving.

It was necessary to replace the metal boot and the first pipe leading into it. Due to the nature of normal ductwork installations, where one pipe goes into the next one to enhance proper air flow, there was a gap where the two fittings connected that could not be reached to be cleaned. So we replaced those two parts and the air vent even though it was necessary to put a hole in the drywall directly below that air vent.

We also encapsulated the entire duct system, paying closer attention to that duct run. Our chemical also happens to work perfectly on drywall, concrete and wood, so while we had the space open we also sealed all around the area where the vent was (between the floor and the ceiling below). This procedure solved the problem with the odor completely.

It is not clear how she was able to get her kitten to stop peeing in the vent.

82mmx cooling coils

What a Summer

HOT!!! Yeah no kidding. Here in Toronto it has been exceptionally hot this summer…but are we complaining? No Way!!

But is your air conditioner complaining? Maybe. Whenever you operate the air duct system for heating or cooling, the bottom of the Air Conditioning coil has a greater chance of clogging with dirt.

This can often cause your coil to freeze up and will definitely reduce your air flow down to almost nothing. Give us a call and we might be able to help you over the phone, and if not, then one of our friendly technicians will be happy to stop by and help with your cooling needs.

Here is a useful video that explains some ways of how to stay cool during our extremely hot summers.

Dirty Dryer Exhaust Ducts

Dirty dryer exhaust ductwork

From one single dryer in a customer’s home to dozens of commercial machines in a coin laundry, City Duct Cleaning cleans all dryer exhaust ductwork big and small.

And whether the dryers are gas-fired or electric, that doesn’t matter either. They all produce the same amount of lint, and you’d be very surprised to see how quickly the lint builds up in your ductwork.

City Duct Cleaning does dryer duct cleaning in homes, condominiums and in places of business such as laundromats, hotels, retirement homes and more!

Air Duct System Repairs

Air Duct System Repairs

Here are some examples of why it makes good sense to keep your air duct systems in good repair. The photos below show some of the recent dryer exhaust ducts that we have cleaned, but the principle applies to any air duct system whether it is for an exhaust system or for heating or cooling in a home or a business.

The first set of photos shows a broken 90 degree elbow that was found by our inspection camera or duct cam. The duct being photographed in this case is in a retirement home. We measured it out and broke a hole in the ceiling, and the dryer lint that fell out of the hole onto the floor was enough to fill five green garbage bags. You wouldn’t believe how much lint there was above that ceiling.

Duct cleaning is obviously our company’s main business, but I’ve been in the HVAC industry for almost 30 years as well, and have installed hundreds of new furnaces, central air conditioners, electronic air cleaners, HEPA systems, humidifiers and even complete duct systems. So doing minor duct repairs such as this one was not difficult for us to manage at all.

I’ve been finding out from my customers over the years that it was quite hard for them to find a heating company who is even interested in doing duct repairs of any kind, and several people have told me that. Most of the companies that they called before they found us said they basically do new installations only.

The same applies to dryer exhaust ducts as well. If you need your’s to be replaced, re-routed or to have a brand new one installed from scatch, or if you need new outside vents with bird screening installed, give us a call. We are here to serve you. Providing excellent service for reasonable costs and winning loyal customers is what we do best.

The second set of photos shows the state of a dryer exhaust duct that we found. The duct system was previously cleaned by another duct cleaning contractor and this is the way they closed the access hole… with duct tape only!

Duct tape is good for many things, but it is definitely not meant to act as a permanent fix in this situation. The hole had very rough edges, so they obviously didn’t even know how to use their sheet metal snips. All that was required to make this one right was to remove all the tape, trim the metal to make it flat, and then to simply screw a metal plate on it. It took me longer to go downstairs to my truck and come back with a metal plate than it did to fix the ductwork.

My best advice when looking for a duct cleaner to do any job, whether it is in your home or in a business or commercial establishment is not to assume that all duct cleaning companies are equally knowledgeable or reputable.

It amazes me sometimes how people can get away with doing such shoddy work. In this case, the duct went for 16 feet, had two turns seperated by 12 feet of duct, and then there was a stack 90 where the duct went into a riser. And from there it went up six floors to a fan on the roof… and there was not a single access hole anywhere else to be found. So how did they clean this duct system? There absolutely has to be access into the duct system at the bottom of the riser. Always. Anyway, we fixed everything up and made this one work like new again.

Getting back to duct repairs, from patching holes to adding a new vent to re-routing or moving duct runs or even your main ducts, at City Duct we do it all, residential or commercial. Call us if you need any of these things done. We’d be glad to help.
