While Lysol can eliminate problem odors, if your ducts have mildew in them, Lysol won't be enough.
Combine 1/4 cup white vinegar with 2 cups water in a plastic spray bottle and shake vigorously. Spray the solution very lightly into the air duct. Don't saturate the surface or allow any of the solution to drip down into the air duct. Allow the sprayed solution to dry.
The best DIY project for your HVAC system involves the good old vacuum cleaner. Keep the floor grilles and wall duct registers clean with the vacuum brush attachment. If there's a lot of dust, unscrew the grills and hose out the visible interior of the ducts. Also, don't forget the cold-air returns.
The reality is, the vast majority of homes and businesses do not need their air ducts sanitized after the ducts are cleaned. In fact, the National Air Duct Cleaner's Association (NADCA), says the best method for cleaning and decontaminating air ducts is to use the source removal cleaning method.
A cleaning every 5-7 years by a company that doesn't make the duct cleaning a waste of money can provide relief from a whole host of problems. Proper duct cleaning can reduce the amount of dust being pushed out into the home by the HVAC system. Another reason for duct cleaning, is renovations to the home.
Clean your malfunctioning air conditioner unit because it has A) a dirty evaporator coil, B) a clogged condensate drain line, or C) a filthy air filter. Install duct filter pads in your vents to control the smell. Apply DIY odor-control methods such as baking soda to your air ducts.
“If your ductwork is over 15 years old, you probably should replace it. Ductwork has a maximum lifespan of 20-25 years. By 15 years, however, it begins to deteriorate, significantly reducing your HVAC system's efficiency, so replacement is the prudent option.”
Installing UV lights like the Biocide Chamber above or below your air conditioner's coils therefore helps eliminate bacteria, mold and mildew by killing the organisms with UV light.
In homes with dirty air ducts, occupants may experience symptoms that are similar to the symptoms of allergies, including coughing, sneezing, and runny nose. Mold, dust and other contaminants lurking in your ducts could also cause sore throat, headaches and even dizziness.
How HVAC UV lights work. UV lights are effective, but they work in a specific range. They'll kill organic growths, such as mold or bacteria, but they have no effect on dust, pet dander or other allergens.
5 Signs You Should Have Your Ducts Cleaned
- You Haven't Changed the Air Filter in Months.
- The Registers and Vent Covers Have Visible Dust.
- You Detect Mold in or Around Your HVAC System.
- Airflow Isn't Consistent From Room to Room.
- You Can Hear Noises in the Ductwork.

Dust accumulation in your home is a product of airflow, either because too much dirty, dust-filled air is floating around your home or because not enough air is spreading through the home, allowing dust to settle.
Clean Your Ducts Every Three to Five Years
As a rule of thumb, the National Air Duct Cleaners Association (NADCA) suggests cleaning your ducts every three to five years.The fact of the matter is this: the average air duct cleaning for most homes costs between $300 and $500, with the price affected by factors like the size of the home, the number of ducts and their configuration. The average price for air duct cleaning is $35 per vent.

5 Ways to Improve Airflow in Your Home
- Check Vents and Registers. One of the simplest things you can do to increase airflow in your home is to check the vents and registers in each room.
- Turn on Ceiling Fans. Another simple solution for improving airflow is to turn on your ceiling fans.
- Schedule HVAC Maintenance.
- Consider Duct Cleaning.
- Invest in a Ventilator.
How to Prepare for Air Duct Cleaning
- CLEAR A PATH AROUND OR UNDER EVERY REGISTER AND FAN IN THE BUILDING.
- DO A WALK-THROUGH WITH YOUR TECHNICIAN.
- ASK LOTS OF QUESTIONS.
- DECIDE WHETHER YOU'LL STAY OR GO.
- MAKE SURE YOUR PROFESSIONAL COMPANY IS TRULY PROFESSIONAL.
Flex ducts are better for existing trunk-and-branch heating and cooling systems. This is because they're more versatile and flexible. Metal ducts are more rigid due to the nature of steel, making them ideal to build an entire HVAC system. In comparison to metal duct, flex duct is easier and faster to install.
Too often, flex ducts are not installed properly, and they end up kinked, bunched up, undersized, or sagging. These issues can cause increased resistance in the duct system, resulting in too little airflow reaching a building's heating and cooling equipment.
Gage-It Right
The thinnest acceptable sheet metal for ductwork used in a single dwelling is 28 gage or 0.013 and 0.018 inches for galvanized and aluminum, respectively. This measurement is for around duct smaller than 12 inches in diameter and a rectangular section no bigger than 8 inches.You can save that money by taking on the ductwork installation yourself. The ductwork (sheet metal duct) in this style home is usually fairly easy and straight-forward. Do It Yourself Hvac: The Design. A proper design must be performed to determine your furnace, air conditioner, and duct sizing.
Even well sealed and insulated
ducts will leak and lose some heat, so many new energy-
efficient homes place the
duct system within the conditioned space of the home.
Designing and Installing New Duct Systems
- Close all exterior doors and windows.
- Close all interior room doors.
- Turn on the central air handler.
Residential Duct Sizing Guide
10 inches per 100 feet of lineal duct. This "Equal-Friction" method of duct sizing should be adequate for normal residential furnace heating and air conditioning applications. Larger volumes or higher static pressures should be dealt with on an individual job basis.Galvanized steel and aluminum are the most common materials for sheet metal ducts. Aluminum in particular is relatively light and easy to install. They are also the least likely to harbor dangerous molds or growths because they have non-porous surfaces. Fiberglass lined ducts.
The ductwork in most homes lasts between 10 and 15 years before problems arise. If your ducts are more than 15 years old, have them replaced before major issues such as pests, gaps, or even collapsed sections of ducts appear.
Furnace ducts that deliver hot air in cold months can be used for air-conditioning.
