Duct Cleaning

An A.C. Rimmer duct cleaning technician uses specialized tools to dislodge dirt and debris in your airflow systems. Whole-house duct cleaning includes cleaning your system’s supply and return air ducts and registers, grills and diffusers, heat exchangers and cooling coils.

Think about what’s really in “a breath of fresh air” that comes from your air duct:

That’s right, all of the skin that sloughs off during the course of a day ends up back in your duct work.

All that dust that swirls around your house has to go somewhere, and back into the vents is where it ends up.

Most people don’t realize the amount of dust mites that are found in their environment, but it’s pretty astounding. There can be up to 40,000 in every single piece of dust.

Even if you’re taking preventative measures with your pets, such as frequent vacuuming, regular baths for the critters, and anti-allergen filters, pet dander tends to hang in the air and end up in the duct work, thus increasing the amount of harsh allergens in the air.

Air ducts are a fertile breeding ground for germs, bacteria, viruses, mold, mildew and fungi .

External pesticides are nasty enough that people are buying produce that is certified to not use them, but they’re also quite stubborn. When they are used, whether on the grass in our neighborhoods or even miles away on the local farm, they make their way into our homes and infest the air we’re breathing.

Cigarette smoke can cling in the air and its toxins are cancer causing, even when exposed to your ducts, the carcinogens are still being exposed to you and your family’s air supply.
