These are companies who are more interested in getting your money, through misleading advertisements or “bait and switch” mailers than actually doing the work properly and improving your indoor air. The very worse thing you can do is to hire a company that may actually create more of an indoor air problem for you and your family due to improper cleaning or use of inferior air duct cleaning vacuums with no more vacuum power than a large Wet/Dry vacuum with a rotating brush attached at the end of the hose, or use a “carpet cleaner” who is not properly licensed or certified to clean air systems. Be especially suspicious of companies advertising low one price duct cleaning service, it’s like providing a one price to paint the exterior of your home whether it be 1 story or several stories high.
Knowing that your home is clean is a great feeling. Knowing that your home air is clean is an even better feeling. Having your air ducts cleaned regularly is key to making your home safer and more comfortable for you and your family. Since we breathe in around 10,000 liters of air a day, the quality of the air in our homes greatly affects our quality of life. So we mean business when we say that air-duct cleaning is a must. Air duct cleaning involves the general maintenance and washing of various heating and cooling system components, such as the supply and return air ducts of your system. It’s just a matter of time before HVAC components get contaminated with pollen, dust particles, mold (if moisture is present), and other debris. These can bring on allergy symptoms and affect your health in other negative ways, so make air-duct cleaning a priority for the healthiest home possible.
We had an appointment with a 2-hour window that Griffen Services made; No one came or called. We had to call their phone service to find out what was going on.I was told installers should be there. At the end of our conversation, the installers pulled up.We called Griffen Services 3 times throughout the day leaving messages with their phone service, We also called our sales person twice and left messages with no return calls. We decided not to use their services based on their customer care or lack of it. I would not refer anyone that values their time to Griffen Services.
Q. Just bought an older house. When we turn on the whole house fan, even with lots of windows open, some air is still drawn through our vents. This causes severe alergy attacks for my wife. The previous owners never had the furnace serviced, weren't the cleanest people, and had several cats. I can only imagine how nast all of the air ducts are. I cleaned out a couple of the reurn ducts and they were nasty with dust and construction debris. I want to have the system cleaned out well. I've gotten several quotes that vary pretty greatly in cost $179-$450. We have a small home with a finished basement that also has heating ducts. I want to choose a service that will do a great job, but have heard that some do a much better job than others. How do I know what to look for, or ask for in a good air duct cleaning service?
Our technique cleans your entire dryer vent system twice – once from the outside and once from the inside – so you can be sure the job has been done right.  According to dryer manufacturers, your dryer vent must be producing about 96 cubic feet of air per minute at a velocity of 1100 feet per minute in order for your dryer to be operating efficiently and safely.  We test your system using a sophisticated thermo-anemometer to be sure that you are getting the proper air velocity and volume at the vent cap.
The first step is to clean the lint trap after every load of laundry. By doing this simple cleaning regularly, you will avoid 90% of dryer vent problems. You should perform extensive cleaning annually, or sooner if you suspect a problem. Unplug your dryer and pull it out from the wall, then disconnect the exhaust tube from the dryer and the wall, and clean it with a vacuum.

On the other hand there are many more air duct cleaning companies that will properly clean the air system and air ducts and use commercial negative air duct cleaning vacuums with at least 2,000 CFMs of vacuum power and utilize proper agitating tools to move the contaminates within the duct work to be captured with HEPA filters and contained by the air duct cleaning vacuum equipment.

"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."
