Understanding Indoor Air Quality (IAQ)

The Importance of Prioritizing IAQ

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. It's a crucial aspect of indoor environmental quality, impacting everything from respiratory health to overall well-being.

Understanding and maintaining good IAQ is essential because we spend significant time indoors, whether at home, work, or school. The air we breathe indoors can significantly affect our health, productivity, and quality of life.

Poor IAQ can result from various factors, including inadequate ventilation, excess humidity, and pollutants like dust, mold, and volatile organic compounds (VOCs).

Let's examine these key factors influencing IAQ:

  • Humidity levels: Humidity levels must also be managed, as high and low humidity can contribute to poor IAQ. High humidity can promote mold growth, while low humidity can cause respiratory discomfort and dry Ventilation systems: Ventilation plays a critical role in diluting and removing these pollutants, ensuring a continuous supply of fresh air.
  • Indoor pollutants: Pollutants can originate from various sources, including building materials, household cleaning products, and outdoor air entering the building.

Fortunately, homeowners can proactively improve IAQ and create a healthier living environment by understanding what affects air quality the most.

Common Indoor Air Pollutants

Indoor air pollutants are diverse and can come from numerous sources, making it essential to identify and address them to maintain good IAQ.

Common indoor air pollutants include:

  • Dust: Dust is a ubiquitous pollutant that can accumulate on surfaces and become airborne, leading to respiratory issues and allergies.
  • Mold: Mold is a type of fungus that thrives in damp environments. It can release spores into the air, causing allergic reactions and respiratory problems.
  • VOCs: VOCs are chemicals emitted as gases from various products, including paints, cleaning supplies, and building materials. These compounds can cause short- and long-term health effects, ranging from eye and respiratory tract irritation to more severe conditions like liver and kidney damage.
  • Pet dander: Pet dander, consisting of tiny flecks of skin shed by cats, dogs, and other animals with fur or feathers, is another common indoor pollutant. It can trigger allergic reactions and exacerbate asthma symptoms.

These pollutants can enter indoor environments through various means, such as outdoor air infiltration, household activities, and the use of certain products. For instance, VOCs can be released when paints and cleaning agents are used, while mold can grow in areas with high humidity or water damage. By identifying the sources of these pollutants, homeowners can take targeted measures to reduce their presence and improve IAQ.

Measuring IAQ

Measuring IAQ is a critical step in identifying potential problems and ensuring a healthy indoor environment. Various tools and methods are available to assess IAQ, ranging from simple DIY kits to professional-grade equipment.

Common tools include air quality monitors that measure levels of pollutants, such as:

  • Carbon dioxide (CO2)
  • Carbon monoxide (CO)
  • Particulate matter (PM)

These devices provide real-time data, allowing homeowners to track changes in IAQ and take immediate action if necessary. Additionally, professional IAQ assessments can involve more comprehensive testing, including the analysis of air samples for specific pollutants like mold spores and VOCs.

Regular IAQ assessments and monitoring are essential for maintaining a healthy indoor environment. By keeping track of IAQ levels, homeowners can identify trends and potential issues before they become severe health hazards. For example, a sudden increase in CO2 levels might indicate inadequate ventilation, while elevated PM levels could suggest the presence of dust or other particulate pollutants.

Regular monitoring also helps in evaluating the effectiveness of IAQ improvement measures, such as the installation of air purifiers or the implementation of better ventilation strategies. By staying vigilant and proactive, homeowners can ensure their indoor air remains clean and healthy.

Health Impacts of Poor Indoor Air Quality

Respiratory Issues

Poor IAQ can profoundly impact respiratory health, leading to issues such as asthma, allergies, and chronic bronchitis. When indoor air is contaminated with pollutants like dust, mold spores, and VOCs, it can irritate the respiratory system and exacerbate existing conditions.

For instance, individuals with asthma may experience more frequent and severe attacks when exposed to high levels of indoor pollutants. Allergens like pet dander and dust mites can trigger allergic reactions, causing symptoms such as sneezing, coughing, and itchy eyes. Chronic exposure to poor IAQ can also lead to the development of chronic bronchitis, characterized by persistent cough and mucus production.

Numerous studies have established a clear link between IAQ and respiratory health, showing exposure to indoor pollutants can worsen respiratory symptoms and increase the risk of respiratory infections.

For example:

  • A study published in the American Journal of Respiratory and Critical Care Medicine found that children exposed to high levels of indoor pollutants were more likely to develop asthma and other respiratory conditions.
  • Another study published on the NLM highlighted that individuals living in homes with poor ventilation and high humidity levels were at a greater risk of experiencing respiratory issues.

These findings underscore the importance of maintaining good IAQ to protect respiratory health.

Cardiovascular Effects

In addition to respiratory issues, poor IAQ can also have significant cardiovascular effects. Indoor air pollutants, such as fine particulate matter (PM2.5) and carbon monoxide (CO), can enter the bloodstream and affect heart health. Exposure to these pollutants has been linked to an increased risk of heart disease, hypertension, and other cardiovascular conditions.

For instance, fine particulate matter can cause inflammation and oxidative stress, leading to the development of atherosclerosis (hardening of the arteries). Carbon monoxide, a colorless and odorless gas, can reduce the amount of oxygen carried by the blood, putting additional strain on the heart.

Relevant research findings support the link between IAQ and cardiovascular health: 

  • A study published in the Journal of the American College of Cardiology found that long-term exposure to indoor air pollutants was associated with an increased risk of cardiovascular events, such as heart attacks and strokes.
  • Another study published by the National Institutes of Health highlighted that individuals living in homes with high levels of indoor pollutants had higher blood pressure and an increased risk of developing hypertension.

These findings emphasize the need for effective IAQ management to protect cardiovascular health and reduce the risk of heart-related conditions.

Mental and Cognitive Health

The impact of poor IAQ extends beyond physical health, affecting mental and cognitive well-being as well. Exposure to indoor pollutants, such as VOCs and mold, has been linked to various mental health issues, including stress, anxiety, and depression. Poor IAQ can also impair cognitive function, leading to difficulties in concentration, memory, and decision-making. For example, high levels of CO2 and other pollutants can reduce oxygen levels in the brain, affecting cognitive performance and overall mental clarity.

Scientific studies provide evidence of the link between IAQ and mental health: 

  • An Environmental Health Perspectives study found that individuals exposed to high levels of indoor pollutants reported higher levels of stress and anxiety.
  • A Harvard study highlighted that poor IAQ in office environments was associated with reduced cognitive function and productivity.

These findings underscore the importance of maintaining good IAQ to support mental and cognitive health. By ensuring clean and healthy indoor air, individuals can improve their overall well-being and enhance their quality of life.

HVAC Systems and Their Role in IAQ

How HVAC Systems Work

HVAC systems, which stand for Heating, Ventilation, and Air Conditioning, play a crucial role in maintaining indoor air quality. These systems are designed to regulate indoor temperature, humidity, and air circulation, creating a comfortable and healthy living environment.

The primary components of an HVAC system include:

  • The furnace or heat pump
  • The air conditioner
  • The ductwork
  • The ventilation system

The furnace or heat pump heats the air while the air conditioner cools it. The ductwork distributes the conditioned air throughout the building, and the ventilation system ensures a continuous supply of fresh air.

HVAC systems contribute to IAQ by filtering out pollutants and maintaining optimal humidity levels. Air filters within the HVAC system capture dust, pollen, and other airborne particles, preventing them from circulating indoors. Advanced filters, such as HEPA filters, can remove even smaller particles, including mold spores and pet dander.

HVAC systems also help control humidity levels, preventing the growth of mold and mildew. Proper ventilation is also essential, as it helps dilute indoor pollutants and bring in fresh outdoor air. By understanding how HVAC systems work, homeowners can appreciate their role in maintaining good IAQ and take steps to ensure their proper functioning.

HVAC Efficiency and IAQ

When filters become clogged with dust and debris, they can restrict airflow and reduce the efficiency of the HVAC system. This can lead to increased levels of indoor pollutants and poor IAQ. As a result, regular filter replacements are crucial for maintaining good IAQ and ensuring the HVAC system operates efficiently.

Duct leaks are another common problem that can affect IAQ. Leaky ducts can allow pollutants from unconditioned spaces, such as attics and crawl spaces, to enter the indoor air, introducing dust, mold spores, and other contaminants into the living environment.

Poor ventilation is also a significant issue, as it can lead to the buildup of indoor pollutants and inadequate fresh air supply. Ensuring proper ventilation and addressing duct leaks can help improve IAQ and create a healthier indoor environment. By being aware of these common HVAC problems and taking preventive measures, homeowners can maintain good IAQ and ensure their HVAC systems operate efficiently.

Improving Indoor Air Quality

Ventilation Strategies

Proper ventilation is essential for maintaining good IAQ, as it helps dilute indoor pollutants and bring in fresh outdoor air. There are several strategies homeowners can use to improve ventilation, including natural ventilation and mechanical systems. Natural ventilation involves opening windows and doors to allow fresh air to circulate indoors. This can be particularly effective in mild weather conditions when outdoor air quality is good. However, natural ventilation may not always be sufficient, especially in areas with high outdoor pollution levels or extreme weather conditions.

Mechanical ventilation systems can provide more consistent and controlled ventilation. There are two primary types of ventilation systems: 

  1. Exhaust fans, typically installed in kitchens and bathrooms, help remove moisture and pollutants from specific areas.
  2. Whole-house ventilation systems, such as energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs), provide continuous ventilation by exchanging indoor air with outdoor air while minimizing energy loss.

These systems can be particularly beneficial in tightly sealed homes, where natural ventilation may be limited. By implementing effective ventilation strategies, homeowners can improve IAQ and create a healthier indoor environment.

Air Purification Methods

Air purifiers are another effective tool for improving IAQ by removing pollutants from indoor air.

There are various types of air purifiers available, including HEPA filters, UV purifiers, and activated carbon filters:

  • HEPA filters are highly effective at capturing small particles, such as dust, pollen, and mold spores, making them an excellent choice for individuals with allergies or asthma.
  • UV purifiers use ultraviolet light to kill bacteria, viruses, and mold spores, providing an additional layer of protection against airborne pathogens.
  • Activated carbon filters are effective at removing odors and VOCs, making them ideal for homes with strong chemical smells or tobacco smoke.

The effectiveness of air purifiers depends on several factors, including the type of pollutants present and the size of the area being treated. For optimal results, homeowners should choose air purifiers that match their specific needs and ensure they are appropriately sized for the space.

Regular maintenance, such as replacing filters and cleaning components, is equally essential for maintaining the effectiveness of air purifiers. By incorporating air purifiers into their IAQ improvement strategies, homeowners can reduce indoor pollutants and create a cleaner, healthier living environment.

Regular Maintenance and Cleaning

Regular maintenance and cleaning are crucial for maintaining good IAQ and ensuring HVAC systems operate efficiently. This includes routine tasks such as replacing air filters, cleaning ducts, and inspecting HVAC components. Dirty or clogged filters can reduce the system's ability to capture pollutants, leading to poor IAQ.

Regular filter replacements are essential for maintaining good IAQ and ensuring the HVAC system operates efficiently. Additionally, cleaning ducts can help remove accumulated dust and debris, preventing them from circulating indoors.

Regular maintenance also involves inspecting HVAC components for potential issues, such as leaks, blockages, and wear and tear. Addressing these issues promptly can prevent them from affecting IAQ and HVAC efficiency.

In addition to HVAC maintenance, regular cleaning of indoor spaces is essential for reducing indoor pollutants. This includes dusting surfaces, vacuuming carpets, and cleaning upholstery to remove dust, pet dander, and other allergens. By incorporating regular maintenance and cleaning into their routines, homeowners can maintain good IAQ and create a healthier indoor environment.

Practical Tips for Homeowners

DIY IAQ Improvement Tips

Improving IAQ doesn't always require professional intervention; there are several simple and cost-effective steps homeowners can take on their own. One effective strategy is using houseplants, which can help filter indoor air and remove pollutants. Plants such as spider plants, peace lilies, and snake plants are known for their air-purifying properties.

Another tip is to reduce the use of products that emit VOCs, such as certain paints, cleaning supplies, and air fresheners. Opting for low-VOC or VOC-free products can significantly reduce indoor air pollution.

Controlling humidity levels is also essential for maintaining good IAQ. Using dehumidifiers in damp areas, such as basements and bathrooms, can help prevent mold growth and reduce moisture levels.

Homeowners can further improve ventilation by regularly opening windows and using exhaust fans in kitchens and bathrooms. Regularly cleaning and vacuuming indoor spaces can help remove dust, pet dander, and other allergens. By implementing these simple DIY tips, homeowners can improve IAQ and create a healthier living environment.

Why Sand & Salt Corrode AC Units in Coastal Florida (And How to Protect Yours)

By Josh Heverly • October 31, 2025
Coastal life around Panama City, Panama City Beach, 30A, and the Gulf Coast comes with a hidden HVAC tax: salt, sand, and relentless humidity. Left unchecked, they shorten equipment life, raise energy bills, and trigger midsummer breakdowns. Here’s what’s happening to your system—and how to stop it. Why corrosion speeds up near the coast! Salt aerosol from the Gulf rides the breeze as a fine mist. When it settles on your outdoor condenser, it mixes with humidity and forms a thin, conductive film. That film drives galvanic corrosion where dissimilar metals meet (aluminum fins, copper tubing, steel fasteners). Repeated wet/dry cycles —foggy mornings, sunny afternoons—accelerate pitting on coils and rust on cabinets and hardware. At the same time, sand and fine debris lodge in the coil’s fins. That clogs airflow, forces the compressor to work harder, and traps salty moisture against the metal—multiplying corrosion and choking efficiency. Early warning signs White, chalky residue or dark spots on coil fins Rusted screws, fan guards, or cabinet edges Louder outdoor unit, longer run times, or poor cooling on hot afternoons Refrigerant leaks from pitted coils (often after a storm season) How to protect your AC (what works on the Gulf) Choose coastal-rated equipment. Factory ecoat/epoxycoated coils , stainless or coated hardware, sealed electrical compartments, and UV resistant paint stand up better to salt air. Rinse with fresh water—regularly. With power off , hose the condenser top to bottom monthly in season and after storms . Avoid pressure washers and harsh chemicals; they bend fins and strip protective layers. Apply professional coil coatings (when appropriate) . After a deep clean and neutral rinse, a compatible coating adds years of protection. (The wrong product can insulate the coil—use HVAC specific coatings only.) Elevate, anchor, and place wisely. Install on a composite pad with proper drainage and hurricane tiedowns. Keep clear of irrigation spray and use a codecompliant wind break or fence to deflect direct salt spray - while maintaining manufacturer clearances for airflow. Stop the sprinkler and string trimmer damage. Redirect heads and add a guard to prevent constant wetting and nicked fins. Schedule coastal maintenance. Biannual tuneups plus quarterly freshwater rinses near the beach. We clean coils, treat drains, verify airflow/static pressure, and check coating integrity. Mind the ductwork and filters. Salt and sand that enter through leaky returns or clogged filters end up on the indoor coil. Seal returns in attics/garages and keep to a 1–3 month filter cadence. What not to do Don’t bag the condenser in plastic. It traps moisture and accelerates corrosion. Don’t use acidic cleaners or bleach. They can attack aluminum and protective coatings. Don’t ignore small rust spots. Surface rust spreads; touchups and hardware swaps are cheap insurance. Your coastal plan, done right A Superior Air Conditioning Company specifies coast already systems, applies compatible coil coatings, sets placement to reduce salt exposure, and builds a maintenance schedule that fits your proximity to the surf. Want a quick coastal assessment for your home or rental? We’ll document risks, estimate remaining life, and outline a plan that keeps you cooler, longer—without paying the corrosion tax. Performing HVAC Maintenance Where There’s Lots of Sand in Coastal Florida A Superior Air Conditioning Company Along Florida’s coast, sand + salt + humidity is a tough trio for HVAC systems. Grit works its way into coils and cabinets, sand drifts restrict airflow, and salty moisture accelerates corrosion. The result can be higher bills, hot rooms, and midsummer breakdowns—unless you maintain with the coast in mind. Here’s a practical plan from A Superior Air Conditioning Company to keep systems clean, efficient, and storm-ready. Start with safety and basics Always shut off power at the thermostat and breaker before outdoor cleaning. Keep 2–3 feet of clearance around the condenser. In sandy yards, use a firm base (composite or concrete pad) and consider pea gravel rather than mulch, which can blow into the coil. Keep sand off the outdoor coil Monthly freshwater rinse (in season): With power off, hose the coil top to bottom to wash out sand and salt. Skip pressure washers and harsh chemicals; they bend fins and strip protective coatings. Deflect the grit: Reaim sprinklers and leaf blowers away from the unit. If wind funnels sand directly at the condenser, add a codecompliant wind break or louvered fence , preserving manufacturer clearances. Cabinet touchups: Surface rust spreads fast near the coast. Lightly clean, dry, and touch up paint or replace corroded screws with coated/stainless hardware. Control sand at the return—filtration that fits Sand that bypasses doors and windows winds up in your return duct and on the indoor coil. Use a properly sized filter with a snug fit. Start with MERV 8–11; only step up to MERV 13 if your system can handle the added resistance. Change filters more often in peak season—monthly is common near beaches. Label sizes and dates on the return grille. Seal gaps around return boxes and avoid double filtering (a filter at the grille and at the air handler) unless a tech verifies airflow is still healthy. Protect the coil and drain inside Evaporator coil cleanliness is key to moisture removal. If you see ice, heavy dust, or musty smell at vents, schedule a professional coil cleaning. Keep the condensate line clear : pour a cup of white vinegar into the clean out every month; confirm steady drip at the outlet. Add float switches to prevent overflow during heavy use. Ducts and rooms that collect sand Entry areas, garages, and beachside rooms can load the system with grit. Seal and support flex duct in the attic so it doesn’t suck in hot, sandy air through tears or loose collars. Insulate metal boots and seal ceiling gaps with mastic/UL181 foil tape (never cloth duct tape). Use door mats and shoe zones to reduce tracked sand; it truly helps filters and coils last longer. Seasonal tuneups that pay back A coastal tuneup with A Superior Air Conditioning Company includes coil rinses, electrical and safety checks, static pressure and temperature split readings, drain treatment, and a corrosion review. For homes closest to the beach, we often recommend quarterly coil rinses and, when appropriate, HVAC safe coil coatings. What not to do Don’t bag the condenser in plastic; it traps salty moisture. Don’t run the fan on ON continuously; it can reevaporate water from the coil. Use AUTO . Don’t ignore small airflow changes—sand can clog coils quickly after a windy weekend. Bottom line: In sandy, coastal environments, simple habits— monthly rinses, tight filtration, clear drains, and coastalaware tuneups —keep comfort high and costs low. Need a coastal maintenance plan tailored to your home or rental? A Superior Air Conditioning Company is ready to help.

Preparing Your HVAC For Panama City’s Rainy Season

By Josh Heverly • October 29, 2025
Between June and September, Panama City weather brings torrential rain, heavy humidity, and the occasional tropical punch. That one-two combo can strain the heck out of your HVAC system—provoking mold, short circuits, and potentially pricy breakdowns. The good news? A little prep goes a long way. Here’s what to do beforehand to preserve your comfort before the clouds come. Biggest Threats to your HVAC Maintenance in the rainy season Flooding & Water Damages Floods can create immediate water damage or a more subtle, long term water damage that gradually progresses and hidden. Pooling water can flood outdoor units and corrode electrical components in low-lying neighborhoods like Millville and St. Andrews. H3 2) Mold & Mildew Growth The very air becomes sticky, fueling microbial growth in ductwork and on damp coils that not only degrades air quality but also efficiency. H3 3) Backed-Up Drain Lines Debris carried by the wind and persistent moisture can plug condensate drains, causing the pan to overflow with noxious liquid and spill onto your floor. H3 4) Power Surges & Lightning Strikes

Fighting Mold in Bay County’s Humid Climate: HVAC Solutions

By Josh Heverly • October 26, 2025
Bay County’s long cooling season, seabreeze humidity, and frequent summer storms create perfect conditions for mold. The good news: the right HVAC strategy controls moisture, protects your home, and keeps air healthier—without sky high energy bills. Here’s a practical plan tailored for Panama City, Panama City Beach, Lynn Haven, Callaway, and surrounding communities. Know the Targets: RH and Dew Point Mold needs moisture. Keep indoor relative humidity (RH) at 50–55% or lower and try to maintain indoor dew point under ~60°F. A $10–$20 hygrometer in a few rooms tells you if your home is trending too damp, especially after storms or power blips. Step 1: Tune the AC for Dehumidification Airflow & sizing: Oversized systems cool fast but remove less moisture. We verify load (Manual J) and airflow (cfm/ton) so the coil stays cold long enough to pull water from the air. Fan setting: Use AUTO, not constant “ON,” which can reevaporate water off the coil back into the ducts. Coil cleanliness: Dirty evaporators and clogged filters slash latent (moisture) removal. Routine cleaning and the right filter cadence matter. Step 2: Add a WholeHome Dehumidifier Your AC isn’t a dehumidifier. A dedicated wholehome unit tied into the return/ supply handles shoulder seasons, rainy spells, and nights when temperatures drop but humidity stays high. We set it to maintain ~50% RH without overcooling the house. Step 3: Seal the Envelope the Right Way Duct sealing & insulation: Leaky or uninsulated attic ducts pull hot, wet air into the system and sweat at the boots—prime mold spots. We seal with mastic (not cloth tape), insulate, and correct crushed or sagging flex. Tight returns: Return leaks in attics or garages are a hidden moisture source. Ventilation: In Bay County, balanced ventilation via an ERV (energy recovery ventilator) tempers incoming air and limits moisture spikes better than simple outside air taps. Step 4: Manage Condensate and Hidden Moisture Clear drains & pans: Float switches, clean outs, and proper slope prevent overflows that soak drywall and closets. Attic checks: Insulate metal boots, fix air leaks, and address “ghosting” (dust lines at studs) that signals infiltration. Bath & laundry: Exhaust fans should actually move air; we verify flow and recommend humidity sensing timers. Step 5: Filtration & Coil Protection Filters: Rightsized MERV 11–13 (if your system can handle it) captures spores and dust that feed mold. UV on the coil: UVC lights keep the wet coil surface cleaner between services, reducing biofilm growth. (They’re for surfaces—not wholeroom sterilization.) After Water Intrusion or a Storm Dry fast. Run AC in Cool with AUTO fan and operate your dehumidifier continuously until RH falls below 55%. Visible mold larger than a small patch or any flooded air handler/ducts warrants professional remediation and HVAC inspection before restart. Why Homeowners Choose A Superior Air Conditioning Company We’re a local, veteran owned team that designs coast already, mold resistant solutions: correct sizing and airflow, whole home dehumidifiers, duct sealing, condensate safeguards, and maintenance plans that keep RH in check. We document temperature split, static pressure, and RH so you see real progress—not guesses. Concerned about humidity or musty odors? Schedule a moisture and HVAC performance assessment with A Superior Air Conditioning Company. We’ll pinpoint the cause and implement a plan that keeps your Bay County home drier, cleaner, and more comfortable year-round. Inspecting Your Ductwork After a Hurricane Storm A Superior Air Conditioning Company When a hurricane powers through the Gulf Coast, the most expensive HVAC damage is often hidden—inside your ductwork. Floodwater, wind driven rain, salt spray, and debris can leave ducts wet, leaky, contaminated, and inefficient. Here’s a clear, homeowner safe guide to assess your system and decide what to fix or replace. Safety First Keep power off to the air handler if flooding is suspected. Do not start a flooded system. Watch for electrical hazards, sagging ceilings, and contaminated water. Wear gloves, eye protection, and a quality mask if you enter attics or crawlspaces. Document everything with photos for insurance. Where to Look Air handler/closet: Check the drain pan, float switch, and cabinet for standing water, rust lines, or oily residue. Attic or crawlspace ducts: Inspect flex runs for kinks, crushing, torn outer jackets, loose straps, or separated collars at the plenum and boots. Metal ducts and boots: Look for open seams, missing mastic, corrosion, and gaps where the boot meets the drywall. What Counts as Damage Water intrusion: Wet or sagging duct insulation, damp liners, or water in supply boots. Persistent musty odors from vents are a red flag. Disconnections & leaks: Gaps at takeoffs, plenum seams, or return drops can pull hot, humid, dusty attic air into the system, driving mold and high bills. Contamination: Sand, insulation fibers, rodent debris, or salt residue carried by wind and surge. Crushed airflow: Flattened flex or tight bends that starve rooms of supply air. Quick Checks (No Special Tools) With the system off , remove a few supply registers and flashlight the first 1–2 feet. Look for moisture, dirt lines, or microbial growth. Inspect return grilles; dirty streaks around grilles often indicate leaks on the return side. Only after you’re sure everything is dry and safe, turn the system on and listen for whistling (leaks) and feel for unusually weak airflow. Do’s and Don’ts Do seal small air leaks with mastic or UL181 foil tape (never cloth “duct tape”). Do replace soggy insulation around boots and repair ceiling gaps to stop infiltration. Don’t “sanitize” flooded flex duct —replacement is typically the correct remedy because moisture penetrates the liner and insulation. Don’t run the fan on “ON” continuously during drying; use AUTO so moisture doesn’t reevaporate from the coil back into the ducts. Restore IAQ and Efficiency Bring indoor RH below ~55% using AC (on COOL, fan AUTO) and, ideally, a wholehome dehumidifier. For metal ducts that weren’t flooded but collected debris, consider professional cleaning to recognized standards and then reseal and re-insulate. Balance airflow and verify performance (temperature split, static pressure) after repairs. Harden for the Next Storm Elevate and secure the air handler; add float/overflow switches. Use corrosion resistant boots and properly supported flex with long, smooth bends. Seal ducts with mastic, not tape; insulate with a vapor barrier jacket. Add surge protection and schedule routine coil and drain maintenance. How We Can Help A Superior Air Conditioning Company provides post-storm duct inspections, moisture and performance testing, written documentation for insurers, leak sealing (mastic/UL181), flex and boot replacements, dehumidification solutions, and IAQ restoration for homes and rentals across Bay County.
