First of all, I think it is great that there are many companies out there who look out for the customer and protect their interest. Secondly, I think it is also important that customers consider having their HVAC systems checked thoroughly before moving into a new home. I have heard a couple of horror stories where previous owners have not had the best housekeeping skills. Even when the appearance of the home seems it has been well kept, keep in mind that surface clean only goes so far. You can never tell what lies underneath.
I just bought a home, and the sellers clearly never had the air ducts cleaned. This is, unfortunately, typical of their neglect of the home, so I am not surprised. I was cleaning around the wooden floor registers, and I took the registers off. I found nests of some sort...all kinds of really gross stuff!! I am calling now to schedule duct cleaning for my new home. Anyway, it is very easy to check to see if you really need duct cleaning. Remove the floor registers and use a flashlight if necessary to see if there is dust or debris in the ducting. If these look bad, I'd definitely have the system cleaned. I would also do it after a construction project, after installing a new furnace, etc. I have found that once I had my previous system cleaned, it seemed to remain spotless for 3 years. So it seems that if you just change your filters on time (I have an iPhone alert set for every 3 months), the system will stay clean for years. Hope this helps!
AC units and thermostats have built-in delay features when they're shut down and then repowered. The delay can be as long as 10 minutes. And, if you've subscribed to an energy-saving device from your local power utility, the unit can take even longer to reset. If you've installed the parts shown and reinstalled the disconnect block, repowered the circuit breaker, turned on the switch at the furnace, moved the thermostat to AC mode and lowered the temperature below the indoor temperature, and the unit doesn't fire up after 30 minutes, it's time to call a pro.
With the split system, the evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity, so that short lengths of duct handle air from the indoor unit to vents or diffusers around the rooms.
Your HVAC unit and air ducts deliver heated or cooled air throughout your home year-in and year-out. The air your HVAC unit produces travels through your ductwork and heats or cools your home via the air vents in each room. The dust and other particles in your home’s air are known as particulate matter, which the EPA defines as "a complex mixture of extremely small particles and liquid droplets." The EPA also notes that "particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles." Having clean air ducts means fewer of these particles moving through your home. If you remove your furnace filter and hold it up to the light, you can probably see several hundred of these minuscule particles floating in the air.
Duct cleaning is a complete scam, I was a “duct cleaning technician” for a whole week before I was fired for not upselling elderly widowed women $2000 extra for “toxic mold remediation” when their ducts were spotless to begin with. The last two days I was employed there I worked as a “helper” alongside a technician thats been with the company 7 years. He scammed every customer on mold and would at times get as much as $2500 extra for treating “toxic mold” in a typical 3 bedroom house in the suburbs. Wait…it gets even better, the “Biocide” the company used was simply a cheap $4.99 per gallon bought at Home Depot air freshener with no anti-microbial properties that was fogged into the HVAC system for 5 minutes, maybe using 1/2 cup of the stuff. In order to provide the customer with evidence of “mold infestation” the technician would be given bogus mold tests that always resulted in “toxic spores present” regardless if you swabbed the actual duct or nothing at all. Not to mention the actual duct cleaning job (typically $400) did basically nothing and the homeowner could’ve done a better job with a shopvac
Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.
Installation: The old furnace is disconnected from the ductwork plenum, exhaust flue, gas and electrical hookups. In most cases, a new plenum must be made onsite or ordered from a local sheet metal fabricator. A new vent might be required too. The furnace is set and reconnected. Adjustments to the blower fan speed and burner are made to optimize furnace performance for your home and climate.

Refrigerant Metering Device -- Every HVAC system has one of these, and heat pumps have two. They regulate the amount of refrigerant going through your air-conditioner. If it fails, either too much or too little refrigerant will course along the lines and either not perform well or will overwhelm the compressor and cause it to fail. A total failure of this component will result in a complete loss of operation.

I was able to get a next day appointment with them last week after multiple other providers did not have availability. The tech was on time and did a good job to diagnose and eventually replace the circuit board and get it up running again. The service itself would be 5 stars, although it did take a week to complete the job due to ordering the part.
I hope that those customers you have with breathing problems don't follow your advice too closely. You are doing them a disservice. Dirt in your ducts does not always stay there, depending on what the contaminants are. I bet you tell your customers not to worry about mold either- just to kill it with bleach. Educate yourself before opening your mouth- You may kill someone someday with your opinion.
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.
I can’t believe I got ripped off by this Air Duct Cleaners. I called them for this $63 coupon per furnace unlimited vents then when they came after he checked it all I hear is I have molds and leak all is worth $499, $799, $899 per furnace but I told him to just clean the duct and patch the single leak per furnace worth $38 each. Still eanding $899 total. All the work he done is in less than an hour he didnt even go to each vent to clean it. All he did is to path the air leak on that entry pipe to the furnace and open the main venting system, vacuum it, and wash the floor of the vent with a solution. Overall time is about 20 mins talking with me discussing all the option which thinking they made me think I don’t really have an option and 40 mins wash and vacuum he took pictures of before and after of only one furnace. He gave me a receipt without the details on what he has done in the house just the name and price. I think we may need a strict law to punish and control all this companies who do this so other company who do good will despise them.
Hello, I read your comment and I know it was two years ago but I hope you see my message. I am trying to figure out what to do as I was told that there is some cat odor in the finished basement. I think with the air conditioning running that it may carry odor. The litter boxes are always kept clean. I wonder if odor can be trapped in the ducts, if Air Duct Cleaning could help, but it is quite expensive plus I'm concerned that it may not help. Please elaborate as to why you think it doesn't work that well. Do you have any other advise? Did you work in the field of Air Duct Cleaning? Thanks so much!
I live in Port Orange, FL. I purchased a double wide mobile home and was saddened to learn that the previous owners were HEAVY smokers! They did a good job “hiding” the smoke smell the day we viewed this place. I did not have a home inspection done unfortunately. My question is: can duct cleaning remove the smoke smell from this place. The ceilings have been treated with Kilz and paint. I personally scrubbed down every wall, floor or surface. I also purchased a ODORFREE OZONE machine. It seemed to remove the odor for a short period of time but my friends are again complaining about the “smoke” odor in my home. The Ozone machine was $400 and I’m terribly upset that it didn’t clean the air as was promised.
The heat pump gained popularity in the 1950s in Japan and the United States. Heat pumps can extract heat from various sources, such as environmental air, exhaust air from a building, or from the ground. Heat pumps transfer heat from outside the structure into the air inside. Initially, heat pump HVAC systems were only used in moderate climates, but with improvements in low temperature operation and reduced loads due to more efficient homes, they are increasing in popularity in cooler climates.
Internal insulation provides better acoustical (noise) control. Flexible duct is very low cost. These products are engineered specifically for use in ducts or as ducts themselves, and are tested in accordance with standards established by Underwriters Laboratories (UL), the American Society for Testing and Materials (ASTM), and the National Fire Protection Association (NFPA). Many insulated duct systems have operated for years without supporting significant mold growth. Keeping them reasonably clean and dry is generally adequate. However, there is substantial debate about whether porous insulation materials (e.g., fiber glass) are more prone to microbial contamination than bare sheet metal ducts. If enough dirt and moisture are permitted to enter the duct system, there may be no significant difference in the rate or extent of microbial growth in internally lined or bare sheet metal ducts. However, treatment of mold contamination on bare sheet metal is much easier. Cleaning and treatment with an EPA-registered biocide are possible. Once fiberglass duct liner is contaminated with mold, cleaning is not sufficient to prevent re-growth and there are no EPA-registered biocides for the treatment of porous duct materials. EPA, NADCA and NAIMA all recommend the replacement of wet or moldy fiber glass duct material.
This article was very good. It should be noted that the EPA building in Washington, DC, was cited years ago as one of the worst "sick building syndrome" buildings. Wish you had mentioned about having people's dryer vents cleaned since they can cause so many fires in homes. Most homeowners forget to check the air flow on the dryer vent. Our company, which cleans by NADCA standards, does both air ducts and dryer vents. Thanks again for keeping the public informed, especially regarding the cost of air duct cleaning...you get what you pay for...don't be fooled by the lowest cost out there. Frequently these are bait and switch companies or will keep adding on features they say a customer needs until the price is so high it's ridiculous.
Had duct cleaners here coupon for 40.00 for complete home I was not here but my husband was. I told my husband that they will prolly ask for more money and I was right. 85 extra to do duct cleaning which I pled because my dryer vent was full of animal hair extensions then for 600 to clean a/c coils I said no. Just do what the coupon said. Do your homework be 100 steps ahead of these con men rember they con people all day long and know the ans to your objections
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.
Good article, but it fails to point out that leaky return-side ducts could be drawing dust and allergens into the duct system from the enclosed spaces in which they run, e.g. between walls, below floors, attic. So duct cleaning may only be a temporary solution. The homeowner can get a home energy audit -- free in many states -- to determine if they have significant duct leakage. An Aeroseal dealer may be able to effectively seal up the duct system without needing to tear into walls etc to get to the ducts.
Furnace Circuit Board -- The furnace circuit board controls a variety of functions. It not only handles the regular operation of the furnace, it also monitors the furnace's various safety circuits. Over time, vibrations from the furnace can weaken solder point and cause them to separate. Dirt and debris can cause short-circuits that damage the board. Failure of the circuit board can cause a variety of effects ranging from the fan not turning on to the complete shutdown of the furnace.

Unfortunately, manufacturers and contractors don’t publish this information…it’s a secret. Why? Who knows…but we have access to a full contractor pricing database of 1,000’s of different units in our online HVAC installation cost calculator, so let’s choose one for our example calculation. We’ll go with Carrier equipment, since our readers always bother us about them (despite us telling them that they are overpriced):
Sounds like your first hvac company was ripping you off. Ask your new company to go to your coil and see if there is a leak. If there isn't the last company was just lining their pockets. If you have had ducts unhooked for a long time I would recommend duct cleaning, trust me I'm not a fan of duct cleaning myself. I have done hvac for 20 yrs. in GA. When I just bought a home built in 1996, we had all the ducts replaced immediately.
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:
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).
