These are the prices for a proper installation from a professional – as a word to the wise, HVAC systems require fine tuning and the custom fabrication of parts during installation to work properly, otherwise they will likely fail prematurely. But there are plenty of people who will do it for cheaper than this, using substandard, used, or stolen equipment (stolen from construction sites and new housing developments). Or, they are using unskilled laborers with no experience, etc. But HVAC is not a “we’ll figure it out trade;” there is a right way and a wrong way to do things. There are just too many predatory companies out there, so be careful. I’d highly recommend not skimping on your HVAC contractor. If you go cheap, you will typically pay more in the long run...and in California, that will be a lot!
An example of a geothermal heat pump that uses a body of water as the heat sink, is the system used by the Trump International Hotel and Tower in Chicago, Illinois. This building is situated on the Chicago River, and uses cold river water by pumping it into a recirculating cooling system, where heat exchangers transfer heat from the building into the water, and then the now-warmed water is pumped back into the Chicago River.[24]
Heaters exist for various types of fuel, including solid fuels, liquids, and gases. Another type of heat source is electricity, normally heating ribbons composed of high resistance wire (see Nichrome). This principle is also used for baseboard heaters and portable heaters. Electrical heaters are often used as backup or supplemental heat for heat pump systems.

Capacitors -- Capacitors help your HVAC motor start from a standstill. Over time they can weaken. As they weaken, they cause the motor to run hotter. This can shorten the life expectancy of your motor. Once a capacitor fails, the whole motor will stop working. You usually won't notice that a capacitor has weakened until your motor stops turning on.
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.

We moved to a house built in 1965 from a 1915 house with a dirt basement. Against what I anticipated, the 1965 house was much dustier. It was like felt on top of everything. I cleaned and cleaned and it did become less dusty over time. We then found out a cat lady with over 2 dozen cats lived in the house in the past. We then had to get our furnace replaced and I was able to look down some of the duct work, the dirt and debris was 3-5 inches deep. Additionally, the basement ducts were entirely plugged with debris including dirt, seeds, ants, toys, etc. I had already removed what I could from those. We had our ducts cleaned last year, and the dust in the house is greatly reduced. Also have lost the runny nose I got after moving here. There are duct cleaning con artists out there, but ours did a good job.


Asbestos removal tip.  Don’t trust any HVAC installation company that says that they will remove asbestos for you. They will do either one of two things: remove it and do a horrible job because they don’t know how (an illegal act in California, finable by up to $250,000), or they will say they did and never actually do it, which is dangerous to your health. Any HVAC contractor worth their weight will know not to touch it. Call an asbestos abatement company – it should cost around $500-$1,000, and your HVAC installation company will come in right after them and do the installation to decrease cost and inconvenience.
Ok what you said is true but in most cases ducts are in a duct flex format, and knowing that the dust in people's flex duct is just surface dust, any real debris that are in the duct itself will result in very little to no air flow which will keep your unit from performing properly, but if it is true allergy reasons then replacing your duct system is better for overall better air quality, plus if you do pay attention to the warranty on flexible duct is that it only has a 10 year warranty and typically only lasts for 20 years so do your research before having a duct cleaning, and to add one more thing if your duct work is completely metal and you can't see visible insulation then your duct on the inside has insulation inside of it, if you replace that with duct work that is clean metal on the inside and wrapped with insulation on the outside then it will further reduce the air bourne fiberglass and dust.
An EER certifies the cooling efficiency of HVAC units. It's calculated by the rate of the cooling in British thermal units (Btus) per hour and divided by the rate of energy input in watts at a specific temperature. The calculation goes as BtuH/WATT at dry bulb (db) versus wet bulb (wb) temperatures. The optimal rating for a cooling unit is about 80db/67wb inside and 95db/75wb outside.

As a homeowner and an owner of rental property I can tell you that the air ducts sometimes need to be cleaned. If you have had pets or anyone smoking in your home (even a visitor) for any length of time, having the ducts cleaned is really good idea. I had a tenant who did not smoke, but got married to a smoker more than year after moving in. When I realized someone was smoking I had them move out, but the smell was awful. I had the ducts cleaned and sanitized (it was a bit extra). The ducts were shiny like new afterwards. I left the windows open for a few days and we cleaned the place super clean and then replaced the carpets. The duct cleaning was worth every penny because the house looked, smelled, and felt new afterward. I plan to have my own house ducts cleaned again this year as we have two cats. We had them cleaned about 12 years ago and they found building materials in the ducts! If you move into a house that has never had them cleaned, it is good to do it. If you have allergies, clean the ducts to see if it helps. You never know what is in your ducts if you have never had them cleaned.
While your HVAC filter is designed to trap particulate matter and prevent it from entering your air ducts, particles often still get through. The number of particles your HVAC filter traps is directly connected to the quality of air in your home: the lower the quality of air, the more particles will be present, and the more particles are likely to get through the filter. If these particles are allowed to build up, your HVAC system can become less efficient, operating longer to heat or cool your home. An inefficient HVAC system can result in inconsistent heating or cooling, higher utility costs, and expensive HVAC unit repairs, such as an A-coil or blower motor replacement if the problem is left unchecked. Air duct cleaning from Sears, which focuses on the dirt in your air ducts, can boost the efficiency of a dirty HVAC system, cleaning out the particulate matter that can hinder HVAC effectiveness and affect your health.
An alternative to packaged systems is the use of separate indoor and outdoor coils in split systems. Split systems are preferred and widely used worldwide except in North America. In North America, split systems are most often seen in residential applications, but they are gaining popularity in small commercial buildings. The split systems are a great choice for small buildings where ductwork is not feasible or where the space conditioning efficiency is of prime concern [20]. The benefits of ductless air conditioning systems include easy installation, no ductwork, greater zonal control, flexibility of control and quiet operation [21]. In space conditioning, the duct losses can account for 30% of energy consumption [22]. The use of minisplit can result in energy savings in space conditioning as there are no losses associated with ducting.
Prices for central-air HVAC systems will vary. The national average to hire an HVAC specialist is $2,920-$3,670 but can run as high as $5,000 or even $12,000 depending on the capacity you need and other factors. Installing central air conditioning requires an entire system that works together to draw hot air out of your home. The system includes an outdoor unit, which houses the condenser and compressor, and the evaporator coils. If you don’t have an existing duct system, ductwork will need to be installed, which will affect labor and material costs. Leaking or damaged ducts will also need to be replaced.
Greetings from Mama Duck from Ductz of Greater Atlanta. These are some awesome comments and a few are from high quality duct cleaners that I personally know. After 19 years in this industry I agree that a government agency is not always up to date with their knowledge but won't admit it. If they were out in the field with our technicians every day they would upgrade their info. I get calls all the time where customers have been taken advantage of by "go and blow" companies. The customers don't know what they don't know but many are too lazy to do the research and are just looking for cheap. The industry has gotten a bad rap due to these con artists but the customer has to take some responsibility. I ask them why they would want to do business with a company who lies to them in print? Are they stupid or just cheap? Thankfully there are those of us in the industry who are working diligently to raise the bar on quality, protect the consumer and perform high quality work. At Ductz all our technicians are NADCA certified, trained by the best in the industry and know how to clean the entire system.
Once i received a call from a Person he Named Steve and He told me that he is from some like GTA Home services and providing Air duct Cleaning in around 105$ and i booked an appointment because he convince me in very will mannered so i agree the services i placed an order and i don't think that they guyz do a great job as he describe but they do same as he told me on phone i'm just surprised that they do a great job and they provide me free inspections of furnace and A/C as well and they really do a great job and they don't waist my money and time. thanks Adam Stevenson and GTA home service Team.
The cooling coils the air comes into contact with appear to need UV-C lights on them in humid climates. That's the biggest thing. If the ducts have never been cleaned, then getting that done goes without saying. But those coils need to be cleaned, disinfected, and then UV-C light(s) installed to prevent mold & bacteria build-up in the future on them. That appears to be chiefly responsible for the dirty laundry and/or sour milk smell coming from forced-air AC systems in humid regions.

Once on the scene, trained Sears professionals utilize powerful, truck-mounted equipment to clear your air ducts of dust, debris, pet dander, allergens, and grime. Our powerful air duct cleaning suction equipment vacuums out years of accumulated dust from your air ducts, leaving them clean and clear. Once finished, our technicians remove all equipment and make sure that your ducts and HVAC unit are restored to their best condition. For continued protection against dirty air ducts, your service technician may suggest a variety of air purification products.

#3 The ONLY time Duct cleaning is needed is when the home had a fire, Bad roof leak on to FIBERGLASS ductwork or house sat vacant for many years with out the air running. And its better to replace than to do “abrasive” duct cleaning. If the duct cleaning has a rotating brush it will remove part of the glue that is holding the Fiberglass in the ducts together, PERIOD no matter how much the say it don’t because the brush is soft.
There is a lot of good, general information in the article. As with anything, the homeowner should do their due diligence in getting enough information to make an educated decision. Should duct-work be cleaned? YES! Does it need to be cleaned annually or even every second or third year? Not necessarily. It all depends on a bunch of variables. You're right that a well designed and balanced system will deliver the right amount of air flow, but sometimes conditions outside the home/business, make it a necessity to get the ducts cleaned. As for mold? NO filter is going to address a mold issue. If you have mold, you have a moisture issue that needs to be addressed. Also, in my 38 years of experience in the HVAC and sheet metal industries, washable filters are one of the reasons ducts need to be cleaned. They are no where near efficient in cleaning/filtering the air to the level that they should.
AC installation in Fort Smith, AR is vital to comfort, safety, and quality of life. The region is infamous for the unbearable heat that can often become debilitating. This is why investing into an AC to improve the overall lifestyle of your family is well worth the cost. Avoid the constant frustration by seeking the assistance of a professional team.
To find companies that provide duct cleaning services, check your Yellow Pages under "duct cleaning" or contact the National Air Duct Cleaners Association (NADCA) at the address and phone number in the information section located at the end of this guidance. Do not assume that all duct cleaning service providers are equally knowledgeable and responsible. Talk to at least three different service providers and get written estimates before deciding whether to have your ducts cleaned. When the service providers come to your home, ask them to show you the contamination that would justify having your ducts cleaned.
