What if you move into a 20 year old house and find that the people who owned it previously NEVER replaced the filter? It was so dirty that the HVAC system did not work at all. For most people - duct cleaning is NOT a waste of time or money. You must not have allergies. I have very bad ones plus asthma. It makes it very hard for me if I don't get it done every few years. By the way - the ducts get dusty just sitting there - especially without air going through them. Dust settles on them just like it does the furniture.
Pro Tips: Before you buy one of the learning thermostats available, you should beware of their shortcomings. First, many require a c-wire to work properly. A common problem is that the old thermostat might not use a c-wire, and this makes it confusing when swapping wires to the new thermostat. Secondly, if you change your thermostat setting often, you might become frustrated with a nest thermostat or other learning thermostat. It will be constantly trying to learn patterns in your random setting changes, and will therefore change your home’s temperature when you don’t want it to. If you have a fairly consistent schedule or don’t mind overriding the unit either manually or via the app on your way home or when leaving, then you won’t experience this issue.
No one has addressed mfg homes and doesn't seem any of the comments are from people in So CA which of course does make a difference as my dust comes from the outside not from the vents. My windows are open pretty much 365 days a year. Secondly mfg homes don't have basements or attics I keep mine clean with my vacuum as they are only about 2 ft deep. I purchased my home 10 yrs ago and it is a high end home but have never had a problem. I clean my furnace filter about twice a month as I have cats and most everything in there is cat fur. I am not saying they don't ever need to be cleaned but I am questioning mfg homes, I also clean my own filters in my AC unit outside as the HVAC guy told me too he QUATITY they would sell. I use this same company every year now for my tune up and inspection which takes them about 10 minutes. Not a bad return for them and I don't mind the $79 fee. If anyone has more info than this on mfg homes please let me know!

Our HVAC Ductwork Installation Cost Guide is the most comprehensive guide of its type. It fully explains the purpose of ductwork and all your options. Pricing is included for all duct types and plenums/drops too. Material and installation costs are listed. Ductwork cost varies greatly by the size and type of duct plus the complexity of the installation, but you can expect to pay $10.20 to $17.25 per linear foot installed.
A Full Installation is the most common type of HVAC installation for a reputable contractor. The ductwork adds two days of labor and about $2,000 to $3,000 to the price, but realize that this is a very important part of your HVAC system. Although it might sound like a good idea to reduce HVAC installation cost and get a quick change-out, realize that there is dirt and debris collecting in your ducts, and the ducts themselves develop holes and full breaks over the lifetime of your unit, all of which may be hidden from sight by insulation. Remember, many contractors will push a quick change-out on you because it is easy and good money for them – you need to be involved and ask questions.
A house breathes just like you an I.For example every time your clothes dryer comes on it automatically creates a negative pressure inside the home.So if air goes out of the living area it has to be replaced.....now look above the ceiling fan ....you see the cover...underneath that is a hole straight to your attic....Now the stuff on your ceiling fan you call dust...call it insulation,rat fecies or anything else that is in your attic that could be pulled in your due to a negative pressure.
WELL, this summer when I opened them up we had black dust spewing from one of the upstairs vents. It resembled the fuzz that comes off new towels. This prompted us to look into duct cleaning. We heard from someone who had it done several times, said it was worthwhile, and knew of a firm that did a good job. Clean Air America sent a single technician for the appointment and after counting registers and ducts gave me a price of $360.00 which included “sanitizing” the system (a $99 additional fee per can used). The small size of the plenum forced him to connect the 8” round vacuum hose from the truck to the 10” square opening from our humidifier unit. In hindsight, a mistake since it reduced the “negative” pressure in the system.
A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements which have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at dehumidifying the internal air. Conversely, a humidifier increases the humidity of a building.

It’s 11 years plus in the industry I have only had to sanitize two systems both were slab systems that were in concrete and could be cleaned with a different method than normal duct cleaning. We were able to use water to rinse out the disinfectant. Would you use a chemical on anything else you use to eat or drink with and not rinse it off? The ducts in your home should be thought of as your homes heart and lungs and breathe the same air that you do. And just like us we wouldn’t use bad chemicals in our lungs and heart.
I did the $49.00 Groupon they just left. Basiclly all they did was stick a shop vac type hose into the vent supply and one return. I also had the dryer done. the person in charge pointed to the main return inside my humidifier and said it needed cleaning. I explained that I was in facility maintaince and would deal with it myself. After that they finished the vac and didn’t try any other sales pitch. I should have read the reviews before I bought this wast of money and time.
To qualify for a tax credit from the federal government, you must save the manufacturer's certificate from your system. The IRS won't require the certificate at the time you file your federal tax forms, but they recommend keeping it with your records in case of an audit. It proves that you purchased a qualifying product. The government offers tax credits for:
All these pro duct cleaners answer with "it's common sense, everything operates better when cleaner" etc. But your explanation is correct. Especially so with flex tube ducting where dust gets "stuck" between the lowest valleys (between wire coil supports) where air flow is drastically reduced -- which is more than 50 pct of the entire interior surface area of the flex ducting. That sounds like a bad thing but also has a good effect of trapping dust from escaping.
1. Ducts need cleaning mostly because they were not installed properly. There should be regulatory inpection and approval of clean and proper duct works on new houses. I was extremely unpset when I looked and found significant amounts of construction dust in parts of the ducts in my new house. There is apparently no way to hold the bullder to be responsible for clean ducts.
I guess, I will start with saying that air duct cleaning is almost never needed. It is not a scam, but it is certainly something that uneducated homeowners get suckered into. In regards to air flow, a well balanced HVAC system should be able to deliver more than enough air flow. If you are not getting good air flow, it's because your system may be out of balance. Additionally, regular cleaning/changing of the air filters will solve about 95% of your problem. Though you would be surprised how many people either a. don't have a filter or b. don't know about it and leave it there for 10+years. a washable one should be cleaned every 6 months(spring and fall) and a disposable one should be replaced every 3-4 months.
I own a small mechanical company. My main work is service and system replacements. I have never been a believer in duct cleaning. The company I worked for before had our duct man come out and do my house. I saw no difference. Preventive maintance is what I recomend. Remove fan and clean, seal fan compartment to prevent dust from being pulled in, filters I install media filters, they are 5″ thick and pleated. I have tested them to make sure static presure was not a issue. Heat exchangers and AC coils need to be cleaned. I will tell you this to do a good cleaning I usually spent 1-2 hrs, When I’m finished I would not have a problem eating my diner on the system. Good filters, clean system and properly tuned up are my recomdation to anyone. I’ve included my email feel free to contact me with any questions. email@example.com
If you’re anything like most of our readers, you’ve spent hours online researching HVAC information in preparation for replacing your old heater or air conditioner. I’m the same way; it’s a big investment! You may want to consider saving yourself some time and money by getting an HVAC-Facts Report from this online HVAC installation cost calculator. Take a look:
The letters in HVAC stand for heating, ventilation and air conditioning. An HVAC system enables you to regulate your home or building’s internal temperature (thermal control) for comfortable living and working. You can bring heat levels down in the summer and up in the winter, keeping your home or office livable year-round. HVAC systems can also help with humidity levels and regulate indoor air quality in a home or office. There are many types of HVAC systems and technologies available.
My best advice has always been that a proper duct cleaning is a valuable investment when moving into a home (new or old), after major renovations and if the ducts have never been cleaned before. It is unlikely that there will be increased air flow, as finding major blockage is unusual, but this will eliminate this as a possible concern if there are air flow concerns. It is also true that the "dust" that is cleared out will most likely never have been distributed through the house unless there has been some work done on the ducts. What is cleared out will be pet hair, toys, clothes, construction material, and biological material (small carcasses and/or feces). Once a proper cleaning is done a follow-up is rarely necessary, but up to the home owners discression.
I recently did some remodeling and figured I’d get the air ducts cleaned in our 12 year old home. After obtaining 4 estimates between $572 and a whopping $3,075 for 25 vents and 2 air handlers, I knew I was in for a ride. I read through this blog and decided to use a $79 inspection camera I just found online (Home Depot) to take a look at all my ducts by removing the ceiling grilles first and then try to get into the ducts from the other end. From what I have just learned here, I believe that will take care of my “concerns”.
Contact/Relay -- Relays are electronically controlled switches that activate the various components of your HVAC system. They manage everything from the power going to the motor to automatic dampers, humidifiers, etc. Most of them are controlled by the thermostat. The most common failure for a relay is being stuck in the "open" position. Separated from its assigned contact point, it fails to complete the connection and send the message to whatever it was supposed to operate. This failure usually occurs from use over time. Each time a relay connects and sends its signal, the electrical arcing from point to point eventually causes wear and tear.
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing (See diagram).
