If you’re concerned about dust, allergens or mold, it may be time to have your air ducts cleaned. The national average cost for air duct cleaning ranges from $190 to $250. Air duct cleaning costs will vary based on a number of factors such as your location in the country, the age and condition of your air ducts, the number of linear feet to be cleaned, and any repairs your ducts may need. HVAC cleaning companies should clearly outline what is included in their services and at what rate, so always make sure you understand and have a written agreement before work begins. Here are some examples of average air duct cleaning costs:
"Over Labor Day weekend at 8pm our A/C system went down -- permanently! Our normal AC company was not working and so we went through the phone book and found Waychoff's! It was unbelievable that one of your employees came to our home at 10PM at no extra charge! On Labor Day the Waychoff's team installed the Trane. They were professional, knowledgeable, efficient, courteous, humorous and extremely likeable. They even brought in cardboard boxes in order to keep my carpet clean. Installation went so fast! They really earned their money, and I assure you that they are not wasting yours. They educated us about the A/C Systems and SEER score. They were great teacher and we learned a lot that day. They assisted us in financing and we were surprised at the monthly payments which were much lower than we expected. The rep from the finance company called us and he was just pleasant and professional as the crew. Later in the week they returned with our 2 rebate forms already filled out and ready to sign! WOW! that kind of service is that! All in all, we are very happy with everything and this house is COLD! We are happy to endorse Waychoff's!"
Clean air ducts are an important component to having a clean home, and therefore it can be a great idea to clean your vent system.  For maintenance purposes, we recommend that your air duct and vent system be cleaned every 3-5 years, depending on a variety of factors including your personal preference, number of pets in the household, cleanliness of the household, and other activities that affect indoor air quality, such as smoking inside.  Air duct cleaning is also a good idea at the completion of a remodeling project, when moving into a new home, or if you experience increased allergies.
We use Rotobrush aiR+ professional air duct cleaning equipment (rotary brush and vacuum) and believe very strongly that this is the best equipment to clean the air ducts in your home.  Our equipment features a camera system so that if you would like, you can see what we are doing as we are doing it.  The Rotobrush aiR+ is designed specifically to handle the soft, flexible ducts in homes in the South. We are able to clean air ducts by inserting the rotating brush into the duct. With the brush rotating at 450 rpm, it loosens any debris that may be stuck inside. While the brush is scrubbing the walls, the vacuum sucks up the debris, leaving your air ducts clean.
A comprehensive duct cleaning takes between 3-5 hours, depending upon the size of your house (and much longer for commercial applications). Most companies, especially the ones that have a price that seems to be “to good to be true”, are in and out of your house in less than an hour and may try to upsell you based on “mold” they allegedly find in your air handler.
Another valuable service that can be offered to you after the HVAC system has been cleaned is anti-microbial fogging. The name of this service is impressive, but the service itself is quite simple. A small chemical fogger is used to introduce chemicals into the ductwork system, chemicals that sanitize germs, bacteria and fungus. EPA-registered chemicals specifically for use in ductwork systems are available that do not require the evacuation of family members and pets from the occupied space while the chemical is being used. We simply add the liquid chemical to the fogger, and fog the supply ducts before replacing the registers. Then turn the central fan on, and fog through the return duct, with the HVAC system's fan helping to distribute the chemical throughout the system. The best news is that fogging can be repeated every 6 months, while system cleaning is at best required every couple of years. Antimicrobial fogging is a simple service that provides real benefits to our customers.

The best way to know if your cleaning was effective is through improved performance of your HVAC system, ideally. You can have before-and-after pictures taken of the ducts (make sure they are of the intake ducts - the ducts that return air into your room), motor and coils. Another tip is smell – sniff the ducts before and after the work is done. Outside of noticeably improved performance, smell and visual evidence are your best indicators.
On the other hand there are a lot more duct cleaning business that will appropriately clean the air system and duct and make use of industrial damaging duct cleaning vacuums with a minimum of 2,000 CFMs of vacuum power and use correct agitating tools to move the contaminants within the duct to be recorded with HEPA filters and consisted of by the duct cleaning vacuum devices.

You should also have air ducts cleaned after recent water contamination or water damage to prevent mold; after renovations or remodeling to ensure debris and dust didn’t settle in the vents and ducts; if you are having problems with allergies or asthma; or when you are moving into a newly purchased home, especially if the previous owners smoked or had pets. The National Air Duct Cleaners Association (NADCA) recommends getting your air ducts cleaned every three to five years, or every two to three years in regions where homeowners use their air conditioning and heater for many months of the year, while the EPA suggests homeowners have duct cleaning done as needed.


Over time, lint and debris accumulate in dryer vents and cause clogs that can lead to a number of dryer vent problems including decreased efficiency. When airflow in a dryer vent is restricted due to clogs, there is an increased risk of fire, carbon monoxide poisoning, wasted energy and time, and excessive wear to clothing, among other negative effects. There are over 15,500 dryer fires each year, and many could have been easily prevented by professional dryer vent cleaning. Dryer Vent Wizard of St. Augustine’s skilled and experienced technicians provide thorough dryer vent cleaning to combat lint accumulation and hazardous clogs.
We 100% guarantee our dryer vent cleaning service for 1 week (excluding normal accumulation of lint and debris).  This guarantee period is meant to give you adequate time to be sure the job has been done properly and to your satisfaction.  If during this period you are not satisfied with the work that was done for any reason, please contact us so we can make it right.
Our air duct cleaning technicians check for dust, dirt, pollen, animal dander and other airborne contaminants that are pulled into your HVAC system every time the furnace or air conditioner runs. Over time, they build up inside your ductwork, making your air duct system a breeding ground for mold spores, bacteria, fungus, mildew and other microbes, which are then re-circulated through your home, impacting the health and comfort of your family.
