Indoor Air Quality in Central and Eastern Wisconsin

Clean, healthy indoor air is essential for comfort, sleep, productivity, and long-term health. In Central and Eastern Wisconsin, seasonal extremes, tight energy-efficient building envelopes, and regional contaminants like pollen and radon make indoor air quality a year-round concern. Aliance Heat and Air Conditioning LLC provides focused indoor air quality solutions for Wisconsin homes that reduce allergens, control humidity, limit pollutants, and maintain consistent ventilation—so your indoor environment supports wellbeing through cold winters, humid summers, and everything in between.

Why indoor air quality matters in Wisconsin homes

  • Long heating seasons mean homes are closed up for months, concentrating indoor pollutants generated by everyday activities.
  • Cold weather increases use of combustion appliances and fireplaces, raising the risk of carbon monoxide and nitrogen dioxide exposure if not properly vented.
  • Hot, humid summers and damp basements encourage mold growth and increase dust mite populations.
  • Spring and fall bring heavy pollen and outdoor molds that enter living spaces without proper filtration and ventilation.
  • Radon, a colorless radioactive gas found in some Wisconsin soils, can accumulate indoors and is a known health risk without mitigation.

Recognizing these regional drivers helps focus the right solutions: whole-home purification and filtration, humidity control, ventilation upgrades, targeted allergen and pollutant mitigation, and ongoing IAQ testing and maintenance.

Common indoor air quality problems we diagnose

  • Elevated particulate matter from cooking, wood burning, smoking, or outdoor infiltration
  • High relative humidity in basements and lower levels leading to mold and musty odors
  • Low winter humidity causing dry skin, sore throats, and static shocks
  • Allergy triggers: pollen, pet dander, dust mite allergens
  • Odors and volatile organic compounds (VOCs) from building materials, paints, cleaning products, and stored chemicals
  • Inadequate ventilation in tightly sealed or recently remodeled homes
  • Combustion byproducts and unsafe carbon monoxide levels from furnaces, fireplaces, or gas appliances
  • Radon presence in basements or slab-on-grade foundations
  • Dirty, leaky ducts spreading dust, mold spores, and pet dander throughout the house

Indoor air quality services and solutions

Aliance Heat and Air Conditioning LLC offers a layered approach to improve your indoor air quality. We pair diagnostics with targeted equipment and maintenance so solutions are effective for your home, your family, and Wisconsin’s climate.

IAQ testing and assessment

A good strategy starts with measurement. Typical IAQ assessments include:

  • Visual inspection of HVAC equipment, ducts, insulation, and moisture-prone areas
  • Measurement of temperature and relative humidity in living spaces and basements
  • Particle counting to assess PM2.5 and PM10 that correlate with smoke, pollen, and dust
  • VOC screenings to detect elevated chemical levels from furnishings and household products
  • Combustion gas testing including carbon monoxide and nitrogen dioxide
  • Radon testing when indicated by local geology or occupant concern
  • Duct leakage testing and camera inspection for suspected contamination

Results are reviewed with homeowners in plain language with prioritized recommendations based on health risk, comfort improvement, and energy impact.

Whole-home air purification and filtration

Filtering and purifying the air through the central HVAC system delivers continuous protection for every room.

  • High-efficiency filters: Upgrading to a properly sized filter with a higher MERV rating (typically MERV 11 to MERV 13 for many homes) significantly reduces pollen, dust, and some fine particles. We evaluate system capability to ensure airflow is not impaired.
  • True HEPA for targeted areas: For rooms with allergy sufferers or immune-compromised occupants, portable or in-duct HEPA units provide medical-grade particle removal.
  • Electronic and media air cleaners: Whole-home electronic air cleaners and advanced media filters can remove fine particulates; selection is based on performance needs and ozone generation risks.
  • UV-C lights: Installing ultraviolet germicidal lights in the return or near the coil helps reduce microbial growth on HVAC components and can lower mold spores circulating through the system.
  • Avoiding ozone producers: We recommend technologies that do not produce harmful ozone and explain tradeoffs so you can choose safe, effective options.

Humidification and dehumidification

Control of indoor relative humidity is central to comfort and mold prevention.

  • Whole-home humidifiers: In Wisconsin winters, maintaining indoor humidity in the recommended 30 to 40 percent range reduces dryness while limiting condensation and mold risk on windows and exterior walls.
  • Whole-home dehumidifiers: During warm, humid months, especially in basements, whole-home dehumidifiers keep humidity below 50 percent, preventing mold, dust mite growth, and musty odors.
  • Local solutions: Crawlspace and basement dehumidifiers, combined with proper drainage and sealing, are often required in older homes with chronic moisture.
  • Smart controls: Integration with thermostats and sensors keeps humidity within optimal bands automatically and adapts settings by season.

Ventilation upgrades

Tightly sealed homes need controlled fresh air with energy-conscious recovery.

  • ERV and HRV systems: Energy recovery ventilators (ERV) and heat recovery ventilators (HRV) bring fresh outdoor air while transferring heat or humidity to reduce energy penalty. ERVs are beneficial in humid climates; HRVs are often chosen for very cold climates.
  • Controlled fresh air intake: Properly balanced mechanical ventilation limits infiltration from uncontrolled sources and reduces pollutant entry during high outdoor pollen or smoke events.
  • Bath and kitchen exhaust upgrades: High-capacity, vented exhaust fans remove moisture and contaminants at source.
  • Duct balancing and sealing: Properly sealed and balanced duct systems deliver ventilation where needed and stop contaminated air from migrating between zones.

Allergy and pollutant mitigation strategies

Mitigation blends equipment, behavioral changes, and targeted fixes.

  • Source control: Identifying and removing or replacing pollutant sources such as old carpeting, pesticide storage, or unvented combustion appliances.
  • Filtration layering: Combining HVAC filtration with portable HEPA units in bedrooms or home offices provides maximum allergy relief.
  • HVAC sanitation: Coil cleaning, drain pan treatment, and duct cleaning when contamination is confirmed reduce biological load.
  • Sealing and insulation: Air sealing at foundations, crawlspaces, and penetrations limits radon and outdoor allergen entry.
  • Radon mitigation: If testing shows elevated radon levels, sub-slab depressurization and other mitigation methods are implemented per industry standards.

The diagnostic and project process

  1. Initial consultation and history: We review occupant symptoms, known issues, renovation history, and seasonal patterns that indicate likely sources.
  2. On-site assessment and measurements: Technicians perform the IAQ tests listed above and document conditions with photos and data.
  3. Findings review and prioritized plan: Results are explained with clear options and expected outcomes for each solution; costs, timelines, and compatibility with existing HVAC systems are covered.
  4. Implementation: Professional installation of filters, purifiers, humidifiers, dehumidifiers, ERV/HRV, UV lights, or ductwork modifications by trained technicians.
  5. Commissioning and testing: Post-installation verification ensures systems operate as intended; sensors and controls are calibrated.
  6. Maintenance plan: Recommended maintenance intervals, filter schedules, and seasonal adjustments to maintain performance and protect equipment longevity.

What to expect from specific upgrades

  • Upgrading to higher MERV filters or adding a media filter: Noticeable reduction in visible dust and allergy symptoms when the system is compatible and filters are replaced regularly.
  • Adding a whole-home dehumidifier: Lower basement humidity, reduced musty odors, and decreased mold staining; improved comfort in summer months.
  • Installing an ERV or HRV: Better indoor air freshness, reduced odors, and lower heating and cooling energy loss compared to simply opening windows.
  • UV-C installation: Decreased microbial growth on coils and better coil efficiency, which can improve airflow and energy performance.
  • Whole-home air cleaner or in-duct HEPA: Continuous reduction in airborne particle counts and relief for occupants with allergies or respiratory sensitivities.

Maintenance recommendations to keep indoor air healthy and comfortable

  • Replace standard filters every 1 to 3 months; high-efficiency media filters per manufacturer guidance, usually 6 to 12 months.
  • Clean or replace humidifier pads/filters before the start of the heating season; winter humidity checks weekly until setpoint is steady.
  • Inspect and clean drain pans and condensate lines annually to avoid microbial buildup.
  • Schedule HVAC inspections and cleaning at least once a year; include coil cleaning ahead of cooling season.
  • Test for radon every few years or after major foundation work, and retest after mitigation to verify results.
  • Use exhaust fans during cooking and showering to reduce moisture and particulates at source.
  • Monitor indoor relative humidity and particle levels with simple sensors to detect trends and catch problems early.

Benefits of timely IAQ action

  • Immediate symptom relief for allergy sufferers and those with asthma or respiratory sensitivities
  • Lower risk of mold growth and structural damage from chronic moisture
  • Improved sleep, focus, and general wellbeing for all occupants
  • Reduced long-term health risks associated with chronic exposure to pollutants like radon or combustion gases
  • Enhanced HVAC efficiency and longevity when coils and pathways are clean and humidity is controlled

Why a professional IAQ approach matters

DIY fixes like air fresheners, single-point purifiers, or simply opening windows may provide temporary relief but often fail to address underlying issues or may introduce new problems. A professional assessment identifies sources, measures concentrations, and creates a balanced solution that accounts for building science, local climate, and occupant health needs. Aliance Heat and Air Conditioning LLC brings decades of HVAC experience in Central and Eastern Wisconsin, ensuring solutions are appropriate for local winters, summer humidity, pollen seasons, and radon risks.

Typical scenarios and recommended system combinations

  • Home with seasonal allergies and a central HVAC system: Upgrade to a MERV 11 or MERV 13 media filter, add a HEPA portable unit in bedrooms, and install an ERV if the home is tightly sealed.
  • New energy-efficient home with stale air complaints: Mechanical ventilation via ERV/HRV combined with a media filter and humidity monitoring keeps fresh air balanced without energy waste.
  • Older home with damp basement and mold spots: Conduct moisture source repair, install a whole-home dehumidifier or dedicated basement dehumidifier, seal foundation penetrations, and run a targeted mold remediation plan with HVAC cleaning.
  • Home near farmland or rural area with dust and pesticides drifting indoors: High-efficiency filtration at the return, controlled intake ventilation, and regular pre-season filter changes reduce outdoor pollutant ingress.

Seasonal considerations for Central and Eastern Wisconsin

  • Winter: Prioritize combustion safety testing, carbon monoxide detectors, and properly sized humidification to reduce dryness while avoiding condensation.
  • Spring: Focus on fine pollen filtration and thorough cleaning of vents and returns after winter to remove accumulated dust.
  • Summer: Dehumidification to prevent mold and dust mite proliferation; consider UV treatment if humidity control alone does not prevent biological growth.
  • Fall: Inspect chimneys and combustion appliances before firing up wood stoves; ensure kitchen and bath fans are venting outdoors and not into attic or crawlspace.

FAQ

Q: How do I know if I need an IAQ assessment?

A: If occupants experience persistent allergy symptoms, chronic odors, frequent condensation, visible mold, unusually dusty surfaces, or if you have concerns about radon or combustion appliance safety, an IAQ assessment will identify sources and solutions.
