Air Duct Cleaning Services
Duct cleaning is a regular part of preventive maintenance for your home and work facility. Just like changing the oil in an automobile, regular duct cleaning increases the heating and cooling efficiency of your HVAC system. According to the U.S. Department of Energy, up to 40% of residential heating and cooling energy is wasted. By cleaning your ducts regularly, you reduce your heating and cooling energy costs by as much as 11%. Read this article and research from the NADCA to learn more.
Indoor air quality is a concern for homeowners, rental property owners, employees, and managers. The HVAC system is the lungs of your home and work facility and as such, needs to be kept clean and maintained. Click here to learn more about how air quality issues affected a local school. The typical six-room home produces up to 40 pounds of dust each year. Dust is the accumulation of organic and non-organic matter – like insects, skin cells, mites, pollen and more. Your HVAC system circulates this air up five times each day. The Environmental Protection Agency claims that indoor air has been found up to 70 times more polluted than outdoor air. We spend 60% to 90% of our time indoors.
Cleanliness and Health
Mold needs three things to survive: Moisture, Nutrients (such as dirt, dust, animal dander, cellulose construction debris from building), and a Surface to grow on. Your ductwork interior can become an unknown breeding ground for fungi, germs, and mold. Better Health Magazine states that, "1 out of 6 people who suffer from allergies do so as a direct result of fungi and bacteria in the air duct system."
Studies have confirmed that contaminated air ducts spread some disease, including salmonella, strep, and legionnaires disease.
We clean brand new homes, hospitals and schools before they even open and extract gallons of drywall dust, construction debris, worker sandwiches, etc. If you see it on the vents, you likely have dirty ducts.
Often owners of homes and buildings state that dust is always on the trim work and they have to dust constantly. Every time your HVAC system kicks on these contaminants are often released out of the dirty ducts and into your building or home.
How do I know if my ductwork needs cleaning?
- If it looks dirty, it probably is.
- If you don’t remember ever having your ductwork cleaned or if you haven’t within the past 5 years, it’s probably time. If your ductwork has been cleaned in the past, you will typically find access doors installed on the supply and return plenums near the furnace.
- Remove a register grill – ones on the floor or near the floor are easiest to remove (often no screws) and peer inside with a flashlight – check several areas for a representative sample. Better yet, stick a digital camera or cell phone camera inside and take a picture.
- Do people in the house suffer from allergies, asthma, or other respiratory problems?
- Do you experience nausea, headaches, itchy eyes, etc. while at home?

How long should it take to clean a typical residential HVAC System?
The amount of time it takes to clean a residential HVAC system depends on many variables such as the size of the home, the number of systems, the extent of the contamination and the number of HVAC cleaners performing the job. Ask at least two contractors to inspect your system and give you a time estimate for your particular system. This will give you a general idea of how long the job should take as well as an idea of how thoroughly the contractor plans to do the job.
A typical 2,000 sq. ft. home averages 4-5 man hours to complete the cleaning.
What is a normal price range for the air duct cleaning service?
At Dirty Ducts Cleaning, we make pricing simple. Residential duct cleaning customer pricing is based on your homes finished square footage and number of furnaces (if more than one). You know your exact duct cleaning price before we arrive. You avoid hidden costs and surprises later. Please contact us with your home's square footage and location for a free phone or email estimate. If you don't know your home's finished squared footage, do not worry, we can look it up for you on the local assessor page.
Commercial duct cleaning customers can contact us to discuss your building's HVAC system. Often we will arrange a site visit with one of our estimators. This can be done during normal business hours and is followed up with a written proposal. Also, if HVAC blue prints are available, we can often create an estimate off of these if you would like to email them. An onsite visit may still be required.
Consumers should beware of "bait and switch" air duct cleaning companies. These companies often charge what appears to be a lesser fee and then once they have their foot in the door they add costs for additional duct mains, additional vents, charging for upper and lower return vents signally, etc. In the end your bill can be 2 to 4 times higher than the original estimate. Be sure to be aware of all hidden charges and small print before booking.
Consumers should also beware of “blow-and-go” air duct cleaning companies. These companies often charge a nominal fee and do a poor job of cleaning the heating and cooling system. These companies may also persuade the consumer into unneeded services with and/or without their permission.
(If you have knowledge of a practicing “blow-and-go” or "bait and switch" air duct cleaner, contact your local Better Business Bureau to report the company, and your local, federal, and state elected officials to demand legislation.)
