Air Duct Cleaning

All we sell is home safety

Improve the Air Quality of Your Home

Millions of Americans have their home heating system and ductwork cleaned every two years, because the accumulation of dirt and dust can block airflow, causing your heating and cooling systems to be less efficient. That accumulation of dirt and dust provides the nutrients for molds, bacteria, mites, and allergens to reproduce and grow. Every time your system's fan is on, it forces these contaminants into the air you breathe.

What Makes the Air Ducts Dirty?

  • Recirculation of dirty air from the duct work
  • Cigarette smoke
  • High-traffic areas or areas with more children
  • Pets that shed high amounts of hair and dander
  • Newly constructed or remodeled rooms
  • Water contamination
  • Fire damage

Causes of a Dirty System

  • Excessive household dust
  • Distinct odor when the system is turned on
  • Headaches
  • Sinus congestion
  • Allergy and asthma problems
Residential vent

Cleaning Procedures

Homeplace Furnace has three professional cleaning procedures:
  • Air Sweep Method
  • Manual Brush Method
  • Elite Rotary Brush Method
Each method uses our personally built truck-mounted vacuums with an 8-inch diameter vacuum hose for proper suction of debris from home. All methods ensure a clean, efficient service. Our equipment includes two-stage air compressors, polyvinyl brushes, and rotary spinning brushes, to give our customers any level of cleaning desired.

Option 1: Air Sweep Method
Our experienced technicians connect a powerful truck-mounted vacuum (equivalent to 68 shop-vacs) to your air system near the furnace, thus creating a larger vacuum out of your ventilation system.

Highly compressed air (250 pounds) is applied with a specialized air gun through each of the supply and return vents at the home, forcing debris and contaminants to the vacuum. The debris in the trunk lines of the ductwork is typically the heaviest. These trunk lines are air swept via a specialized pneumatic agitator/snake, which loosens the contaminants from the interior surfaces of the ducts and forces it into the vacuum. The vacuum carries the debris to a collection point mounted on the service vehicle. This procedure, known as Source Containment, ensures a clean removal from home.

The same vacuum and air pressure tools are used to clean the components of your heating and cooling system, increasing its overall efficiency. We clean the burners, heat exchangers, pilot, blower motor, fan blades, and A-Coil (if accessible). We also check the bearings, belts, and carbon monoxide levels.

Option 2: Manual Brush Method
This is a great service for the homeowner experiencing more dust than usual or a home that has not been serviced for an extended period of time. In addition to the Air Sweep Method, this procedure also encompasses the use manual brushing in the main trunk lines. These duct brushes are made of the polyvinyl material, which gives the ducting interior a good, stiff brushing, but is pliable enough to thoroughly clean the corners and damper areas. The brush is run back and forth, as if the ducting were a chimney lying on its side, providing superior debris removal.

Option 3: Elite Rotary Brush Method (Meets cities of St Paul and Minneapolis Inspector Code Requirements)
This method features the best of all three available options: rotary spinning brushes, manual brushing, and forward and reverses air sweeps. This procedure is ideal for homes that have not been serviced for a prolonged period of time or are experiencing high levels of dust. It is also the best for those who have allergy issues or simply desire the best cleaning possible.

For this service, we remove the registers and run a rotary brush from the register face all the way back to the main trunk line to remove debris - which a few of our competitors offer. Our forward Air Sweep pushes that dirt back to the main trunk line to be removed by the vacuum unit. After cleaning from each register, we manually brush the main trunk lines with the Stationary brushes and follow up with a reverse Air Sweep.

The main trunk lines are typically 2-foot by 2-foot square or rectangular, so a round spinning brush will not clean the top walls, corners or most if the interior. Especially with the 6-inch diameter brushes many of our competitors use, leaving most of the dirt behind.

Homeplace Furnace will manually brush out the main trunk lines with an oversized 2-foot stiff nylon bristle brush. This brushing is similar to brushing a chimney. This is more labor-intensive, but is the proper way to do the service, and does a much better job at cleaning the ductwork.

A word of caution: Many companies offer a Rotary Brush procedure, but rarely are any two the same. Some are quality, and many are low priced "bait and switch" offers. We strive to educate our customers on how to make the choice that is best for them and we do not just try to sell the most expensive service.

The Benefits

Elimination of Bacteria, Molds, and Fungi
Deep in the darkness of your ductwork, anyone can grow a fine crop of mold, mildew, and bacteria with only a minimal base of debris buildup. The fact is, every home has some level of biomatter within the ducts. Allowing the debris and contaminants to accumulate gives the bacteria and molds the perfect environment in which to prosper.

Professional cleaning of the ducts and administering an OSHA- or EPA-approved germicide will dramatically reduce the occurrence of their presence. All products we use are designed for residential procedures and are completely safe. MSDS sheets are available upon request.

Cleaner Living Environment and a Reduction in Housework
The longer the ductwork is allowed to go without a professional cleaning, the more debris and dust accumulate internally. All that then recirculates every time the system goes on. As the air is being pushed through the ducts, it spews dust from every vent throughout your home.

Having the ducts cleaned every two years reduces the circulation of all the trapped debris within. The result is less time spent on household chores like dusting.

Savings on Heating and Cooling Bills
Your heating and air-conditioning system should be cleaned, checked, and lubricated every two years. Removal of rust, carbon, and debris from the interior components such as the burners, blowers, heat exchangers, and pilot assembly will increase the efficiency of your system. The absence of the debris allows the air/fuel ratio to be more correct, keeping the operational costs and carbon monoxide levels at a minimum. In short, the longer a furnace is allowed to go without a cleaning, the higher the carbon monoxide levels and energy consumption.

Fresher, Healthier Air
Every home in America circulates household dust, dust mites and their feces, molds, bacteria, and pollutants from the ductwork. This unhealthy air promotes illness and triggers allergic reactions. Removal of these contaminants on a two-year basis improves the quality of the air in your home or office.

Increased System Efficiency
Practically, all ducting systems have contaminants clinging to the inside walls. Commonly, 1/4″ to 1″ of unwanted buildup can occur in just a matter of a few years inside your ductwork. This process slows down the airflow (drag coefficient) through the ducts and pushes the furnace/cooling system to work much harder than it is designed.

Relief from Allergens
Eighty percent of the debris we call “household dust” is actually shed human skin. We can generate up to five pounds of this each year. The other smaller components include carpet fibers, blown-in soil, pet dander, dust mites (which eat skin flakes) and their feces and miscellaneous pollutants. Scientific research is showing a direct link to allergy problems associated with dust mites. The more skin shed, the more dust mites and more allergies. Clean ductwork significantly minimizes the recirculation of household dust.

Common Questions

How often should I have my ducts cleaned?
Both the furnace, as well as the ductwork will operate at maximum capacity when serviced every two years. However, households with pets or allergy and asthma sufferers may need a cleaning more frequently.

How long will it take to have my ducts cleaned?
Time is dependent upon the size of the home and how difficult it is to remove the debris from the ventilation system. Our powerful equipment and specialized tools allow us to complete the average sized home in approximately 45-75 minutes using the air sweep method. Allow between 60 and 90 minutes for the stationary brush method, and from 1 1/2 to 3 hours for the rotary brush method. Expect more time for larger homes and special situations.

What do I need to do to prepare my home?
Our technicians need access to every heat vent and cold air return. If possible, have large pieces of furniture pulled away from the vents. Also, make sure there is ample workspace around the furnace.
