Understanding Indoor Air Quality

Common Indoor Pollutants

Indoor air quality is often compromised by a variety of pollutants that can infiltrate our homes. Common indoor pollutants include dust, pet dander, mold, volatile organic compounds (VOCs), and carbon monoxide. Dust and pet dander are everyday nuisances that can accumulate on surfaces and in the air, especially in homes with pets. Mold, on the other hand, thrives in damp environments and can release spores that are harmful when inhaled. VOCs are emitted from household products like paints, cleaning supplies, and even furniture, contributing to indoor pollution. Carbon monoxide, a colorless and odorless gas, can be particularly dangerous, often originating from faulty heating systems or gas appliances. Understanding these pollutants and their sources is the first step in mitigating their impact on indoor air quality.

The health effects of these pollutants can be significant. Dust and pet dander can trigger allergies and asthma attacks, while mold exposure can lead to respiratory issues and exacerbate conditions like asthma. VOCs have been linked to headaches, dizziness, and even long-term health effects such as liver and kidney damage. Carbon monoxide poisoning is a severe risk, with symptoms ranging from headaches and dizziness to, in extreme cases, death. By recognizing these common indoor pollutants and their potential health impacts, homeowners can take proactive steps to improve their indoor air quality and safeguard their health.

Health Impacts of Poor Indoor Air Quality

The health impacts of poor indoor air quality are both immediate and long-term, affecting individuals of all ages. Short-term effects often include respiratory issues such as coughing, sneezing, and shortness of breath. Allergies can be exacerbated by indoor pollutants, leading to symptoms like itchy eyes, runny nose, and skin rashes. For individuals with asthma, poor indoor air quality can trigger more frequent and severe attacks, making it difficult to breathe and potentially leading to emergency medical situations. Children and the elderly are particularly vulnerable to these short-term health effects, as their immune systems may not be as robust.

Long-term exposure to poor indoor air quality can lead to chronic health conditions. Studies have shown that prolonged exposure to indoor pollutants can contribute to the development of respiratory diseases, cardiovascular issues, and even certain cancers. For instance, long-term exposure to VOCs has been linked to liver and kidney damage, while mold exposure can lead to chronic respiratory conditions. According to the Environmental Protection Agency (EPA), indoor air pollution is among the top five environmental risks to public health. By understanding these health impacts, homeowners can prioritize improving their indoor air quality to protect their long-term health and well-being.

Identifying and Reducing Sources of Pollution

Eliminating Tobacco Smoke

One of the most significant sources of indoor air pollution is tobacco smoke. Secondhand smoke contains over 7,000 chemicals, many of which are toxic and can cause cancer. The dangers of secondhand smoke are well-documented, with exposure leading to respiratory infections, asthma attacks, and even sudden infant death syndrome (SIDS) in children. To keep your home smoke-free, it is crucial to establish designated smoking areas outside the home. Encourage smokers to use these areas and provide them with ashtrays to prevent littering. Additionally, consider implementing a strict no-smoking policy inside the home to protect all occupants from the harmful effects of secondhand smoke.

Creating a smoke-free home environment involves more than just setting rules; it also requires ongoing vigilance and support. Educate family members and visitors about the dangers of secondhand smoke and the importance of maintaining a smoke-free home. Provide resources for those who wish to quit smoking, such as information on smoking cessation programs and support groups. By taking these steps, you can significantly reduce the levels of indoor air pollution caused by tobacco smoke and create a healthier living environment for everyone in your home.

Managing Household Chemicals

Household chemicals are another common source of indoor air pollution. Many cleaning products, paints, and maintenance supplies contain VOCs that can be harmful when inhaled. To reduce indoor air pollution from household chemicals, opt for low-VOC or VOC-free products whenever possible. These products are designed to minimize the release of harmful chemicals into the air, making them a safer choice for your home. Additionally, always follow the manufacturer's instructions for use and ensure proper ventilation when using these products to further reduce exposure.

Proper storage and disposal of household chemicals are also crucial in managing indoor air quality. Store chemicals in their original containers with labels intact, and keep them in a well-ventilated area away from living spaces. Dispose of unused or expired chemicals according to local regulations, as improper disposal can lead to environmental contamination and pose health risks. By adopting these practices, you can effectively manage household chemicals and reduce their impact on indoor air quality.

Controlling Pet Dander and Dust Mites

Pets bring joy and companionship to our lives, but they can also contribute to indoor air pollution through pet dander. Pet dander consists of tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds, and other animals with fur or feathers. These particles can trigger allergic reactions and asthma symptoms. To reduce pet dander, groom your pets regularly and bathe them as needed. Use a vacuum cleaner with a HEPA filter to capture dander from carpets, upholstery, and other surfaces. Additionally, consider using air purifiers designed to capture pet allergens to further improve indoor air quality.

Dust mites are another common indoor allergen that can impact air quality. These tiny creatures thrive in warm, humid environments and are often found in bedding, upholstered furniture, and carpets. To control dust mites, wash bedding in hot water weekly and use allergen-proof mattress and pillow covers. Reduce humidity levels in your home by using dehumidifiers and ensuring proper ventilation. Regularly clean and vacuum your home, paying special attention to areas where dust mites are likely to accumulate. By implementing these practices, you can effectively reduce pet dander and dust mites, leading to improved indoor air quality.

Improving Ventilation

Natural Ventilation Techniques

Natural ventilation is an effective way to improve indoor air quality by allowing fresh air to circulate throughout your home. Opening windows and doors is the simplest method of natural ventilation, helping to remove indoor pollutants and bring in fresh air. To maximize airflow, consider using exhaust fans in kitchens and bathrooms, where pollutants and moisture levels are typically higher. Cross-ventilation, achieved by opening windows on opposite sides of a room or building, can create a natural breeze that enhances air circulation and improves indoor air quality.

The benefits of natural ventilation extend beyond just improving air quality. It can also help regulate indoor temperatures, reduce humidity levels, and lower energy costs by reducing the need for mechanical cooling and heating systems. To achieve effective natural ventilation, strategically place windows and vents to facilitate airflow and consider using window treatments that allow for ventilation while maintaining privacy. By incorporating natural ventilation techniques into your home, you can create a healthier and more comfortable living environment.

Mechanical Ventilation Systems

While natural ventilation is beneficial, mechanical ventilation systems offer a more controlled and consistent approach to improving indoor air quality. Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) are popular options that help maintain indoor air quality by exchanging stale indoor air with fresh outdoor air. HRVs transfer heat from the outgoing air to the incoming air, making them ideal for colder climates. ERVs, on the other hand, transfer both heat and moisture, making them suitable for a wider range of climates.

Choosing the right mechanical ventilation system for your home depends on factors such as climate, home size, and specific air quality needs. Regular maintenance is essential to ensure the system operates efficiently. This includes cleaning or replacing filters, checking for blockages, and ensuring that vents are not obstructed. By investing in a mechanical ventilation system and maintaining it properly, you can significantly improve indoor air quality and create a healthier living environment.

Kitchen and Bathroom Ventilation

Kitchens and bathrooms are hotspots for indoor pollutants and moisture, making proper ventilation in these areas crucial. In kitchens, cooking can release smoke, grease, and odors into the air, while bathrooms are prone to high humidity levels that can lead to mold growth. Installing and maintaining exhaust fans in these areas can help remove pollutants and moisture, improving indoor air quality. Choose exhaust fans with the appropriate capacity for the size of the room and ensure they vent to the outside, not just into the attic or another part of the home.

Regular maintenance of kitchen and bathroom exhaust fans is essential to ensure they function effectively. Clean the fan blades and grills regularly to prevent the buildup of grease and dust. Check for any blockages in the venting system and ensure that the fans are operating at their optimal capacity. By prioritizing proper ventilation in kitchens and bathrooms, you can reduce indoor pollutants and humidity levels, contributing to a healthier home environment.

Utilizing Air Purification Technologies

Types of Air Purifiers

Air purifiers are an effective tool for improving indoor air quality by removing pollutants from the air. There are several types of air purifiers, each with its own set of advantages and disadvantages. HEPA (High-Efficiency Particulate Air) filters are highly effective at capturing particles as small as 0.3 microns, making them ideal for removing dust, pet dander, and pollen. Activated carbon filters are excellent at removing odors and VOCs, while UV-C light purifiers use ultraviolet light to kill bacteria and viruses. Each type of air purifier has its strengths, and the best choice depends on the specific pollutants you need to address.

When selecting an air purifier, consider factors such as room size, the specific pollutants you want to target, and maintenance requirements. Some air purifiers combine multiple technologies, such as HEPA and activated carbon filters, to provide comprehensive air cleaning. By understanding the different types of air purifiers and their effectiveness, you can choose the best option for your home and improve indoor air quality.

Placement and Maintenance of Air Purifiers

The placement of air purifiers is crucial for maximizing their efficiency. Place air purifiers in areas where you spend the most time, such as bedrooms and living rooms. Ensure that the air purifier has enough space around it for proper airflow and avoid placing it in corners or behind furniture. For larger homes, consider using multiple air purifiers to cover different areas effectively. Proper placement can significantly enhance the performance of air purifiers and improve indoor air quality.

Regular maintenance is essential to keep air purifiers functioning effectively. Follow the manufacturer's guidelines for filter replacement and cleaning schedules. HEPA filters typically need to be replaced every 6-12 months, while activated carbon filters may need more frequent replacement depending on usage. Clean the exterior and air intake vents regularly to prevent dust buildup. By maintaining your air purifiers properly, you can ensure they continue to provide clean and healthy air for your home.

Houseplants for Air Purification

Houseplants are a natural and aesthetically pleasing way to improve indoor air quality. Certain plants are known for their air-purifying properties, such as spider plants, peace lilies, and snake plants. These plants can absorb pollutants like formaldehyde, benzene, and trichloroethylene, helping to clean the air in your home. In addition to their air-purifying benefits, houseplants can also enhance the overall ambiance and aesthetic of your living space.

Caring for air-purifying houseplants involves providing the right conditions for growth. Most of these plants thrive in indirect sunlight and require regular watering, but be careful not to overwater. Ensure proper drainage to prevent root rot and consider using a well-draining potting mix. By incorporating houseplants into your home, you can naturally improve indoor air quality while adding a touch of greenery to your living space.

Regular Maintenance and Monitoring

Routine Cleaning Practices

Routine cleaning practices are essential for maintaining good indoor air quality. Dust and allergens can accumulate on surfaces, carpets, and upholstery, contributing to poor air quality. Use a vacuum cleaner with a HEPA filter to effectively capture dust and allergens from floors and furniture. Microfiber cloths are excellent for dusting, as they can trap dust particles without spreading them into the air. Establish a regular cleaning schedule to keep your home free from dust and allergens, focusing on high-traffic areas and places where dust tends to accumulate.

In addition to regular cleaning, consider implementing practices that reduce the introduction of pollutants into your home. Encourage family members and guests to remove their shoes at the door to prevent tracking in dirt and allergens. Use doormats to trap dirt and dust before it enters your home. By adopting these routine cleaning practices, you can significantly reduce indoor pollutants and maintain a healthier living environment.

Monitoring Indoor Air Quality

Monitoring indoor air quality is an important step in maintaining a healthy home environment. Various tools and devices are available to help you keep track of indoor air quality, such as air quality sensors and smart home systems. These devices can measure levels of pollutants like VOCs, carbon dioxide, and particulate matter, providing real-time data on air quality. Some smart home systems can even integrate with your HVAC system to automatically adjust ventilation based on air quality readings.

Interpreting the data from air quality monitors can help you take appropriate actions to improve indoor air quality. For example, if VOC levels are high, you may need to increase ventilation or reduce the use of certain household products. If particulate matter levels are elevated, consider using air purifiers or increasing cleaning frequency. By monitoring indoor air quality and responding to the data, you can create a healthier living environment for your family.

Seasonal Maintenance Tips

Seasonal maintenance is crucial for maintaining good indoor air quality throughout the year. In the spring and summer, pollen levels can be high, so keep windows and doors closed during peak pollen times and use air purifiers to reduce indoor pollen levels. Regularly change HVAC filters to ensure they effectively capture pollutants and maintain proper airflow. Check for mold growth in damp areas like basements and bathrooms, and address any moisture issues promptly.

In the fall and winter, indoor air quality can be affected by increased use of heating systems and reduced ventilation. Ensure your heating system is well-maintained and clean, as dirty systems can circulate dust and pollutants. Use a humidifier to maintain optimal humidity levels, as dry air can exacerbate respiratory issues. Schedule professional maintenance services to inspect and clean your HVAC system, ensuring it operates efficiently and effectively.

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.
