Why Addressing Indoor Air Quality Can Improve Your Health and Comfort

Modern homes are designed to be energy efficient, which often means they are tightly sealed to prevent heat loss in winter and cooling loss in summer. While this is excellent for utility bills, it can have unintended consequences for the air you breathe. When a home cannot "breathe" naturally, pollutants become trapped inside. Over time, the concentration of particulate matter, chemical off-gassing, and biological contaminants can exceed outdoor levels significantly.

Addressing these issues is not merely about removing unpleasant odors; it is a critical component of home maintenance and personal health. In regions like Salem, IN, where windows are often kept closed during peak weather extremes, the HVAC system recycles the same air repeatedly. Without intervention, this air becomes stagnant and laden with irritants.

Investing in air quality solutions directly targets the source of respiratory fatigue, headaches, and allergy symptoms. By actively managing the indoor atmosphere, homeowners can protect sensitive family members—such as the elderly, young children, or those with asthma—from the compounding effects of poor environmental control. Furthermore, proper air quality management protects the home itself. Excessive humidity can warp wood and promote mold growth, while overly dry air can crack furniture and damage flooring.

Our Comprehensive IAQ Services: What We Offer and When

We provide a multi-tiered approach to indoor air quality, moving beyond simple filter changes to hospital-grade air purification and humidity control. The goal is to integrate these solutions directly into your existing central heating and cooling infrastructure for seamless operation.

Whole-Home Air Purification

Standard fiberglass filters capture large dust bunnies but allow microscopic particles to pass through. We install advanced air purification systems that utilize electrostatic technology and dense media filters to capture particulates as small as 0.3 microns. This includes bacteria, viruses, smoke, and pet dander. These systems treat the air across the entire square footage of the home, rather than just a single room.

UV Germicidal Lights

Biological growth is a common issue within the damp, dark environments of an HVAC coil. We deploy UV germicidal irradiation systems that are mounted inside the ductwork or near the evaporator coil. These lights emit a specific frequency of ultraviolet light that disrupts the DNA of mold spores, bacteria, and viruses, effectively neutralizing them before they can be circulated into your living space.

Humidity Control Systems

Balancing moisture is essential for comfort.

• Dehumidifiers: During humid summers, high moisture levels make the air feel heavier and hotter, forcing your AC to work harder. Whole-home dehumidifiers remove this excess moisture, preventing mold proliferation and making the home feel cooler at higher thermostat settings.
• Humidifiers: In the winter, heating systems strip moisture from the air, leading to dry skin, static electricity, and irritated sinuses. We install bypass or steam humidifiers that introduce precise amounts of water vapor into the airflow, preserving wood furnishings and improving respiratory comfort.

Energy Recovery Ventilators (ERVs)

For newer, airtight homes, fresh air is vital. ERVs exchange stale indoor air with fresh outdoor air without losing the energy used to heat or cool the home. This system transfers thermal energy between the outgoing and incoming air streams, ensuring your home remains ventilated without spiking energy costs.

Understanding the Process: How We Assess and Improve Your Indoor Air Quality

Improving the air inside a home requires a systematic approach based on data rather than guesswork. Our technicians follow a strict protocol to ensure that the solutions implemented address the specific contaminant profile of the property.

• Initial Consultation and Symptom Review: The process begins with a discussion regarding specific issues faced by the occupants. Technicians ask about allergy patterns, noticeable odors, or rooms that feel particularly stuffy.
• Comprehensive Air Testing: Advanced sensor technology is deployed to measure the levels of Volatile Organic Compounds (VOCs), particulate matter (PM2.5 and PM10), carbon dioxide, carbon monoxide, and relative humidity.
• Ductwork and System Inspection: The physical state of the HVAC system is examined. Leaky return ducts can pull in contaminants from attics or crawlspaces, while dirty blower wheels can re-release dust into the supply air.
• Data Analysis and Proposal: Once the data is collected, a report is generated outlining the primary pollutants. A customized solution is proposed, detailing which equipment—such as a UV light or a high-efficiency media filter—will provide the most significant impact.
• Installation and Integration: Approved equipment is installed directly into the supply or return plenum of the HVAC system. This often involves cutting into existing sheet metal, wiring the device into the furnace control board, and ensuring airtight seals to maintain system pressure.
• Calibration and Verification: After installation, the equipment is calibrated. For humidifiers, this means setting the humidistat based on outdoor temperatures. For purification systems, airflow is verified to ensure no restriction occurs. A final test confirms the reduction of pollutants.

Deciding Between IAQ Enhancement and Complete System Overhaul

Homeowners often wonder if adding an air purifier is enough or if the underlying HVAC system needs to be replaced to solve air quality issues. Making the right decision depends on the age of the current system, the condition of the ductwork, and the severity of the contamination.

Allegiance Heating & Air, LLC. helps clients navigate this decision by evaluating the "bones" of the current heating and cooling setup.

When to Enhance (Add-On Solutions)

If the furnace and air conditioner are mechanically sound and less than 10-12 years old, adding IAQ components is usually the most cost-effective path.

• Localized Issues: If the problem is strictly related to seasonal dryness or pet dander, installing a humidifier or better filtration on the existing unit is sufficient.
• Good Duct Condition: If the ductwork is sealed and insulated properly, the existing system can effectively deliver purified air throughout the house without modification.
• Budget Considerations: Add-on components provide immediate relief at a fraction of the cost of a full system replacement — apply for financing today.

When to Overhaul (Replace System or Ducts)

There are scenarios where putting a new air purifier on an old system is ineffective.

• Mold in Duct Board: If the ductwork itself is made of fiberboard and has been compromised by moisture and mold, it cannot be cleaned effectively. Replacement is necessary to stop the contamination source.
• Inadequate Airflow: If the current blower motor is too weak to handle the resistance of a high-efficiency MERV filter, upgrading the furnace or air handler to a unit with a variable-speed motor is required to maintain comfort and filtration simultaneously.
• Severe Contamination: In cases where the interior insulation of the HVAC cabinet is degraded and releasing fibers into the air, the entire unit should be retired to ensure safety.

Regional IAQ Considerations: What Salem Residents Need to Know

The local climate in Salem creates specific challenges for indoor air quality that generic solutions may not address. The region experiences a true four-season climate, meaning homes face high humidity in the summer and very dry, cold conditions in the winter.

• Summer Humidity and Mold Risk: During the warm months, moisture levels can spike. If an AC unit is oversized, it may cool the house quickly but shut off before removing adequate humidity. This "clammy" environment encourages mold growth in carpets, basements, and ductwork. Dedicated dehumidification is often required here.
• Winter Dryness and Virus Transmission: Cold winters force heating systems to run frequently, drying out the air. Dry air causes mucous membranes in the nose and throat to crack, reducing the body's natural defense against airborne viruses. Maintaining humidity between 35% and 50% is crucial during Indiana winters.
• Agricultural and Pollen Activity: Being in a region with significant vegetation and agriculture, Salem homes are subject to high pollen counts and outdoor dust. During harvest and planting seasons, particulate matter in the outdoor air increases. Standard one-inch filters are often insufficient to block these smaller organic particles from entering the home.
