Unseen airborne contaminants are often the root cause of persistent respiratory issues, aggravated asthma, and stale indoor odors that never seem to go away. Schedule your indoor air quality assessment today: contact us for immediate solutions.
Living in the Ohio Valley means dealing with high humidity in the summer and dry, sealed-up homes in the winter, creating a perfect storm for indoor pollutants in New Albany. While standard furnace filters trap large dust bunnies, they are ineffective against microscopic threats like viruses, mold spores, and volatile organic compounds (VOCs). Installing a whole-home air purification system transforms your existing HVAC infrastructure into a defense system that actively cleans the air in every room, rather than just trapping dirt at the intake. Allegiance Heating & Air, LLC. provides comprehensive air quality solutions designed to neutralize threats at the microscopic level:
Backed by full warranties and flexible financing options to make clean air accessible for all.
When you decide to invest in an air purification system, you are not simply buying a filter; you are upgrading the biological safety of your home. The equipment we install integrates directly into your central heating and cooling system. This means that every time your fan runs, the air is treated, scrubbed, and purified before it circulates back into your living spaces.
Many homeowners rely on portable units that only clean the air in a single room. A whole-home solution addresses the entire air volume of the house multiple times per hour. The primary goal is to target the three main classes of indoor air contaminants: particulates (dust, pollen), bio-aerosols (bacteria, viruses, mold), and gas-phase pollutants (odors, chemical vapors).

High-efficiency media air cleaners are the first line of defense. Unlike standard one-inch filters found in hardware stores, these thick media cabinets provide a vast surface area to trap particulate matter without restricting airflow to your furnace.
Filtration captures solids, but ultraviolet light neutralizes biological threats. By installing UV-C lamps within the ductwork or near the evaporator coil, we prevent the HVAC system from becoming a breeding ground for mold and bacteria.
For homes struggling with odors from pets, cooking, or chemical off-gassing, oxidizing systems are essential. These units release safe, natural oxidizers (like hydro-peroxides) into the air stream that actively seek out and break down pollutants in the air and on surfaces.
Integrating an air purification system is a precise technical process that requires understanding airflow dynamics and electrical safety. The installation ensures that the new equipment enhances your current HVAC performance rather than hindering it with static pressure issues.
The process begins with an evaluation of your current heating and cooling equipment. We check the physical space available around the air handler or furnace and measure the static pressure of the ductwork. This step is crucial because installing a high-efficiency filter on a system with undersized ducts can restrict airflow and damage the blower motor. We ensure the selected purification unit matches the tonnage and airflow requirements of your specific system — schedule service today.
To accommodate a whole-home media air cleaner or purification unit, the return air drop (the duct bringing air back to the furnace) often needs modification:
Active purification systems, such as UV lights or electronic air cleaners, require consistent power:
Once physically installed, the system undergoes rigorous testing:
Homeowners with existing air quality equipment often face the dilemma of fixing an aging unit or upgrading to modern technology. Air purification technology has advanced significantly in the last decade, making replacement a more viable option in many scenarios.
If you have a media cabinet that is structurally sound and simply needs a new filter insert, this is standard maintenance. Similarly, if a relatively new UV light system has a burnt-out bulb but the ballast is functioning correctly, a simple bulb replacement is cost-effective.
Older electronic precipitators (the units that "zap" dust) often fail due to broken ionizing wires or power pack failures. These units require frequent cleaning and often emit ozone, which can be an irritant. Modern media filters capture more particulate matter without the ozone byproduct and without the need for monthly washing.
Operating air purification systems in this region requires attention to specific environmental factors. The climate here shifts dramatically between seasons, posing unique challenges for indoor air quality:
Summers in New Albany are notoriously humid. High indoor humidity creates an ideal environment for dust mites and mold growth inside ductwork. While an air conditioner dehumidifies as it cools, it leaves the evaporator coil wet. Without a UV-C light to sterilize this surface, mold colonies can form, releasing spores every time the AC cycles on. A purification system here must address biological growth, not just dust.
During the colder months, homes are sealed tight to conserve heat. This lack of ventilation causes indoor pollutant levels to spike, often reaching concentrations two to five times higher than outdoor air. Combustion byproducts from cooking, pet dander, and shedding skin cells accumulate rapidly. An active air purification system is essential during these months to scrub the recirculated air since opening windows is not an energy-efficient option.
The Ohio Valley is frequently ranked as a challenging region for allergy sufferers due to high pollen counts in spring and fall. Standard fiberglass filters are ineffective against pollen particles. Upgrading to a MERV 11 or MERV 13 media filter is often necessary to provide a sanctuary for residents with seasonal allergies.
While plug-and-play devices exist, they cannot match the efficacy of a professionally installed whole-home system. Professional installation ensures that the air purification solution is engineered to work in tandem with your specific heating and cooling setup.
The most common mistake in air filtration is installing a filter that is too restrictive for the HVAC system. This can lead to frozen AC coils in the summer and cracked heat exchangers in the winter due to overheating. Professionals calculate the total external static pressure to select a filter rating that cleans the air without suffocating the furnace.
HVAC manufacturers often require proof of professional maintenance and proper installation to honor warranties. Installing an add-on component incorrectly can void the warranty of your expensive furnace or air conditioner. Professional installation guarantees that all work meets code requirements and manufacturer guidelines.
UV-C light is harmful to human eyes and skin. Professional installation involves placing these lights deep within the plenum where they cannot be seen, and installing safety interlock switches that cut power immediately if the access door is removed. This ensures the safety of the household while maximizing the germicidal effect on the air stream.
A correctly installed purification system keeps the internal components of your HVAC system clean. A clean blower wheel and evaporator coil transfer heat more efficiently, reducing the workload on the compressor and lowering monthly utility bills. This efficiency gain helps offset the initial investment of the purification system over time.
Waiting to address indoor air quality issues often leads to worsening allergy symptoms and potential long-term respiratory strain. The technology exists to transform your home into a safe haven from pollen, viruses, and mold. By choosing a whole-home approach, you ensure that every breath taken under your roof is clean, fresh, and healthy.
