A: An average size house will take between 3 to 5  hours depending on if its a 2 man crew or a solo tech.

duct-pic-20-150x150A: The Environmental Protection Agency states that “duct cleaning services typically, but not always ” range in cost from $400 to $1000 per heating and cooling system. At Dirty Ducks, we  typically range from $400-$500 for your average home. Bigger homes or homes with multiple furnaces could increase the price and scope of the project. Anything less than that, should raise some red flags and anything in excess of $700 “unless it’s a very large home” is just price gouging. Remember, investing in proper equipment is pricey. Many of the $150-200 “whole house specials” that other companies offer, are cleaned by horribly performing equipment.

A: Stay away from them. They are usually a scam. You cannot do jobs consistently with two employees while using top of the line equipment, and charge that little. We in the industry, call these companies “Blow and Go.” They do minimally effective cleaning with poor equipment. Basically, you’re wasting your money. They will start out with a low price, and then add costs mid job. You should always have the price quoted before the job starts. Also, companies offering that cheap of a price typically don’t have the money to invest in  the proper duct cleaning equipment. Proper equipment set ups are in excess of $20,000. We’ve seen far to many times, companies that use equipment barely worthy of vacuuming out the interior of your wife’s car! Again, the EPA states, and most reputable companies will be in the $400-$1000 price range, depending on the size of the house.

A: Depending on certain factors, such as smoking, pets, allergies or asthma and outside conditions, systems should be cleaned every 5 years on average.

A: Yes! We do have a camera that can scope the insides of your ducts. We can show you exactly what you’re dealing with. This way, you are certain that we did a top notch job.

A: We start by removing every vent cover around the house. Then we hand vacuum every vent to make sure there is no blow back when we come in with the air tools. Once, the vents are clean, we then go through all the vents with air tools that are designed to agitate all the dust and debris in the ducts. While this agitation is the first step in the process, the second step is a large vacuum that will create a negative suction through the system (through the duct work). This is what separates us from our competitors. Dirty Ducks has three different vacuums to choose from. We have a truck-mounted 35 horsepower vacuum, a portable 35 horsepower vacuum, and a 220 volt electric hybrid vacuum. This gives us the ability to match your home with the proper vacuum. Certain homes require a certain vacuum to optimal. If other companies do not have these options, the performance will suffer. With the suction and agitation combined, dust and debris is stirred up and the suction pulls it out. We work out way from the vent ducts, to the main trunk lines. Then from the main trunk lines to the furnace. We finish the job by cleaning out the top and bottom portions of the furnace. This process insures that the entire duct system is cleaned.

How Your System Got So Dirty

Learn why ductwork gets dirty and how to check your own system. Through normal occupation in a home/workplace we generate a great deal of contaminants and air pollutants (dander, dust, allergens, chemicals) which is pulled into the HVAC system and re-circulated 5-7 times a day on average; result there is a natural build-up of contaminants within the duct work over time. All these containment can cause an inefficient system and poor indoor air quality.
