There are multiple reasons to replace your HVAC system. If you have built additions onto your house, you may find your old system no longer meets the requirements for the new dimensions. Perhaps a new technological breakthrough has provided features that will improve your comfort and air quality. Most often, however, you need to replace your system because it no longer works properly.
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls.
If you’re purchasing from a big-box store, you can expect to pay approximately $120-$1,000 for a window unit. Window units are appealing for their quick setup and relatively low cost, but they can use more energy over time than central air and only cool the room in which they’re installed. The price will vary depending on the type of air conditioner you buy and its cooling capacity. Window units, which require minimal installation, are one of the most affordable options on the market. Portable air conditioners don’t have the cooling power of a window unit, but they do have the perk of being transportable from room to room. Expect to pay between $225 and $800 for a portable air conditioner, on average. The cost of an air conditioning system with coils, condenser and line (not including installation or ductwork) can range from approximately $2,000 to $4,000 or more. If you don’t have (and don’t want to put in) ducts, a ductless mini-split air conditioner is a good option, although pricey up front. Pricing can range from $650 to $4,250 per unit on average; you’ll need one unit for each room in which you want temperature control.
We are all getting migraines several times a month. I have asthma but not ever as bad as it has been and my 2 year olds dr just informed me she potentially has asthma too. We all get sinus infections regularly and eczema and contact dermatitis. None of us have been this way until recently in our apartment. A roof leak with mold was repaired recently mold was sealed off not removed. We also had lead paint removed from a few window trims this year. I wasn’t here to see if they covered the vents. We had mice too. I vacuum everyday we have hardwood floors no one wears shoes past the font door and I’m getting over a cup full of dirt every time I vacuum. Dust on everything daily. White dust. It’s a 4 room apartment with 1 intake. They are filthy from what I can see when I change the filters. The filters are black after a few months. I feel bad to ask the homeowner to get the system cleaned, can’t afford to move (we live in the city & it’s expensive). I am going to try the shop vac to remove what I can. Any experienced hvac people please give your opinion. Should I just get it done and pay for it myself? We have lived here for 13 years. It’s never been cleaned since ive been here. Is it something I can do with a shop vac? Can i use a wet rag to get the powder dust on the inside of the vents off. One vent has what looks like chunks of dry wall or thick paint sitting in the vent and none of the vents screw into the wall, the screws just fall out. No one ever reinforced the area so the wall just basically crumbles. Kind of useless to spend the money on filters since the air and dust just blows out around the sides of the vents and one of the vents just falls right out of the wall when the heat is turned on. I don’t know why the owner doesn’t fix it. He’s been here to replace filters and saw the condition.
I always get a laugh at anyone claiming to be in the business for any length of time that doesnt understand the importance of cleaning out a ventilation system. Not only for better indoor air quality but for maintaining your heating equipment. I guess it makes more sense to some people that the furnace will just run better with a ton of dust and debris and maybe this wont be a big cause of sytem breakdown and malfunction. I mean really? Maybe this guy got a bad company and or cleaning and is a little jaded but to advise cleaning your grills , which does nothing, and replacing a filter....come on guy.
And if you have flex duct and/or fiberglass ductboard in your home- the last thing you want is a big brush or anything abrasive running through it. Even high-pressure air can erode ductboard so I wouldn’t clean it with anything. If it becomes contaminated, get rid of it and install real ductwork. If your ductwork is accessible in the basement – the best thing to do is take it down and manually clean it if it’s full of junk. It’s not going to cost a nickel more to do that than to pay $500-1000 for a ‘duct cleaning machine” AKA big blower and vacuum – to do the job.
The answer to your question is most likely "Yes," but not defiitely. It depends on where the dust is coming from. Now, if your house is more than say, 12 years old then you likely do have leaks in your ducts that can let in insulation particles and dust from your attic. If this is the case then cleaning of the ducts-PROPER CLEANING, which like the article sas doess include EVERYTHING that the conditioned air passes through, such as your indoor evaporator coil and blower housing assembly-is definitely a good first step to getting that dust under control! Of course I highly recommend that you also have your ducts SEALED as well, or else you will have to repeat the cleaning some time down the line. As a 3rd step, consider an electronic air filter. I always thought they were a scam, personally, so I never bothered selling them to my clients. Then one day my manager sent me to install one for a senior couple in a mobile home. The wife had bad allergies, and her eyes were constantly watering and puffy and red. Well, I did a quality check 60 days later and she could not stop praising that air filter! Keep in mind that in a mobile home, duct seals are not as complete as those in other homes due to access issues.
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.

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.
My 48 yr old house (mine for the last 4 yrs) has considerable dust in the return plenum (fiber duct). I’m remodeling and recently re-sealed the return plenum AND the site-fabbed transition built when the new unit was installed, 2013. The return was leaky no doubt drawing musty, dusty air from the crawl space due to the Red-Neck fab & seal job! Pitiful craftsmanship! It took me 7 hours to fix the new transition piece. Anyway, the dust in the house is the same “color” as whats in the return duct and I’m getting way too much & too often in the house. I’ve also cleaned my coils, which were not that dirty.
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 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.
Indoor Fan Motor -- Indoor fans circulate the air from your house and through the system. Age and dust buildup are the two biggest contributing factors to their failure. When they are starting to fail they will often make noise. Failure of the fan will result in no heating or cooling, and if it is not repaired soon, it can cause other components to fail.
I’m a heating and air conditioning contractor. I’ve been in the trade for over 15 years. I’ve witnessed numerous duct cleaning projects and talked with many duct cleaners. Duct cleaning as it’s usually promoted is a fraud. Most duct cleaners claim to deliver cleaner air. They deliver exactly the opposite. The studies on duct cleaning prove it, including a May 1998 study sponsored by NADCA and the EPA! The stories are compelling, but they can come up with stories that “prove” anything they want. Internet searches are dominated by results from those who are paid to tell you that duct cleaning is worthwhile. Search a little more and you’ll find the truth.
Humidifiers/Dehumidifiers: Humidifiers add needed moisture to the air in winter and very dry climates. Dehumidifiers remove dampness any time of the year. Central air conditioners dehumidify too, but in very humid climates, you might want to remove humidity without also cooling the air. You have a good range of options for both of these HVAC accessories. Whole-house humidifiers cost $350 to $800 installed, while dehumidifiers are $1,250 to $2,000 or slightly more.
