FAQs
How does a whole-home air purifier connect to my existing heating and air-conditioning system?
Whole-home air purifiers are installed directly into the return-air plenum of your HVAC ductwork, so every bit of air that your furnace or air-conditioner handles is first routed through the purification unit. The purifier runs whenever the blower fan is on, capturing or neutralizing airborne particles before they circulate through the supply ducts. There is no need for a separate power source—most models draw low-voltage power from the HVAC control board—so the system operates seamlessly with your current thermostat and equipment.
What indoor-air-quality problems are common in Seymour, and how can a purifier help?
Seymour’s mix of agricultural activity, seasonal pollen, and humid Midwestern summers leads to elevated levels of dust, mold spores, and outdoor allergens infiltrating homes. During winter, homes are sealed up tight, allowing indoor pollutants such as pet dander, cooking odors, and off-gassing from household products to accumulate. A whole-home purifier fitted with a high-MERV media filter and optional activated-carbon layer traps particulates as small as 0.3 microns, absorbs odors and VOCs, and when paired with UV-C lamps can inactivate mold and bacteria, giving you cleaner, healthier air year-round.
Will running a whole-home air purifier increase my utility bills?
Most modern purification systems add minimal electrical demand—usually less than a 60-watt light bulb—because they rely on your existing blower fan. High-efficiency media filters are designed to maintain low pressure drop, so they do not make your HVAC motor work much harder. While there may be a slight increase in energy use, it is typically offset by improved HVAC efficiency due to cleaner coils and reduced dust buildup on components.
How often do I need to replace filters or perform maintenance?
For a standard 4–5-inch pleated media filter, plan on replacement every 6–12 months, depending on household occupancy, pets, and local pollen counts. Carbon canisters that target odors usually last about 12 months. UV-C lamps should be replaced every 18–24 months to maintain germicidal strength. Aside from filter and lamp changes, the system requires only an annual inspection to verify airflow, seal integrity, and electrical connections—tasks typically handled during your routine HVAC tune-up.
Can a whole-home air purifier really reduce allergens, odors, and airborne viruses?
Yes. High-MERV or HEPA-grade media captures up to 99% of pollen, pet dander, and fine dust, significantly lowering allergen levels. Activated carbon absorbs cooking smells, tobacco smoke, and volatile organic compounds. When equipped with UV-C or photocatalytic oxidation technology, the purifier can inactivate a wide range of viruses, bacteria, and mold spores as they pass through the light chamber, giving your family an added layer of protection.
What is the installation process and how long does it take for a Seymour homeowner?
A typical retrofit takes 2–4 hours. Our technicians begin by assessing your duct layout and selecting a mounting spot that maintains proper airflow. We then cut an access panel, install the purifier cabinet, seal all joints, wire the unit to the HVAC control board, and verify system operation. Because the work is confined to the mechanical room or basement, there is minimal disruption to your living spaces, and the system is ready to run the same day.
