Cleaning

Many Minnesota families are surprised to learn that the cause of their health issues lurks in their home's air ducts. Dust, mold, and other harmful debris can gather in your heating and cooling systems. From there, they are circulated throughout your home. Affecting more than just the health of your family, a dirty system can lead to higher energy bills and decrease the lifespan of your HVAC system.

Along with air duct cleaning, we offer a variety of other services like:

  • Air exchanger cleaning
  • Coil cleaning
  • Sanitizing
  • HEPA air cleaning

When deciding on a business to help you clean your system, remember that not all air duct cleaning companies are the same. The industry offers a variety of methods and equipment that may or may not be as efficient in removing mold and cleaning the air. Most air duct cleaning companies use portable machines that are cheap to purchase, but offer a sub-average quality cleaning.

Clean Air Starts with Quality Equipment

Many HVAC cleaning companies have relatively powerful cleaning systems. Some might feature vacuums that pull in 500 to 2,000 cubic feet of air per minute (or CFM). These, however, are nowhere near as powerful as the equipment we use at Pure Breathing. Our truck-mounted system pulls in 15,000 CFM, which is not just a step up from our competition, it’s a leap ahead.

We also utilize negative air machines to create negative pressure in your home. Highly-trained technicians will create a tight seal around any vent, window, or potential break in your home’s HVAC barrier. Using magnets to secure each seal, we create maximum suction, removing all contaminants from the air.

Our process begins with communication. Before we begin, we discuss our equipment load-in and positioning with our customers. We also inform you about the noise levels you can expect and any potential tripping hazards caused by our air hose.

Our Air Duct Cleaning Process

  • The HVAC system is engaged to make sure it is operating properly. Once we determine everything is operating fine, we turn the system off
  • The furnace filter is removed, wrapped in plastic, and reinstalled to separate the supply and return sides of the system
  • An 8” access hole is cut into the main supply and the return trunk line near the plenum–the main circulating area of an HVAC system
  • The duct mounting flange is installed over the access hole and the flexible ducting is attached with a quick-connect clamp.
  • Once the system is running and under negative pressure, each register is sealed off with plastic sheets or magnets. This will increase air velocity. The use of more than one zone bag may be necessary for larger homes to better manage the airflow
  • Starting from the furthest register, each branch line is cleaned by using nylon duct brushes, cable-driven brushes, or air blast skipper assemblies to loosen debris to the main trunk line.
  • Once all the branch lines have been cleaned, all supply trunk lines are accessed and cleaned
  • Once the supply side has been thoroughly cleaned, we repeat steps 3 through 6 on the return side

After the duct system has been cleaned, we clean the A-coils and the blower fan. An EPA-registered air duct sanitizer may also be applied. Once the system has been thoroughly cleaned and sanitized, the last step is to reseal all access holes with metal patches, then reinstall all registers.

We believe that our NADCA (National Air Duct Cleaning Association) recognized process produces the absolute best results in mold removal and air duct cleaning.
