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:

Jax Vents philosophy is to provide quality service at affordable rates. By having our dryer vent service done on a yearly basis as dryer manufacturers suggest, we can save our customers more in time and energy than our service costs. This gives our customers real benefits and value, with the convenience and security of knowing their dryer is operating efficiently. We believe that delinting your dryer vent regularly will greatly reduce the potential for fires that exists, help reduce energy consumption, minimize dryer damage, and give our customers greater peace of mind.

Nowadays most houses have a central air conditioning system linking air ducting to move conditioned indoor air throughout the house. Gradually, the air system and the linking air ducting will collect dust and other contaminants, which can trigger the blood circulation of unclean and contaminated indoor air through your house. Out-of-sight and out-of-mind health products that we do not believe much about are filthy air system and a duct which could be the unhealthiest product in our house.


Once we have cleaned your entire air duct system, our job is not finished.  All of your vent covers are washed, and before they are replaced we sanitize your system with EnviroCON antimicrobial fogger.  This EPA registered disinfectant is commonly used in hospitals and nursing homes, and works to eliminate mildew and mold in your air ducts.  And, lastly, everything in your home is left exactly as we found it, with no mess left behind!

If you’re spending extra time to dry clothes completely due to a clogged dryer vent, you can bet you’re also spending extra on utilities. Extended or extra drying cycles also mean your clothes will be subjected to more wear and weathering. By hiring a Dryer Vent Wizard and shortening your drying time, you’ll use less power and save your clothing from excessive damage.


How typically should you have your clothing dryer vent cleaned? It relies on simply just how much laundry you do, if you have kids, if you have animals, if your clothing dryer vent exhaust pipe is short, long, or rising through the roofing of your home. As a standard, and recommended by the Insurance protection Company, you have to have the vent cleaned a minimum of every 2 years.
Under normal conditions, standard-use residential ducts (HVAC systems) should be cleaned every three to five years. Usage, system age and condition, local air quality, and number of residents and pets can affect cleaning frequency needs. Harsher conditions might require cleaning as often as every two years. Obviously, if your system is not functioning properly or the output air quality is bad, consult a professional sooner rather than later to get a proper diagnosis.

Negative pressure air duct cleaning is a process in which the ducts are cleaned by hand in concert with compressed air tools to dislodge dirt and debris, which is then vacuumed up and removed. It is considered a superior cleaning method in its efficiency and in preventing dislodged debris from escaping the ducts and contaminating the air in the residence.

"So My A.C. suddenly went belly up and I needed a total brand new unit inside and out. So a little background on myself. I'm an engineer, so I know a little bit about A.C. and how they work. I'm by no means an expert, but it does allow me to detect if the A.C. guy knows his stuff, especially if they don't know what I do. 😉 And I'm happy to say, these guys do. One of the things that helped me chose them is that they brought up the importance of controlling humidity. None of the other contractors I spoke to, mentioned that. I also appreciate the fact that he didn't try to "up sell" me and get me to buy things I didn't need. He was on time, honest and forth coming about what I needed and what I didn't. When the workers came, they were on time, very professional and very CLEAN. After they left, I couldn't tell they had been there. Highly recommended this service."
