FAQs
What is a HEPA filtration system and why is it important for homes in Walland?
A HEPA (High-Efficiency Particulate Air) filtration system captures at least 99.97 % of particles down to 0.3 microns, including dust, pollen, smoke, pet dander, and many airborne pathogens. In Walland, seasonal pollen from surrounding forests and humidity-driven mold spores can aggravate allergies and respiratory problems. A properly sized HEPA system integrated with your heating and air conditioning equipment dramatically reduces these contaminants, giving you cleaner, healthier indoor air year-round.
How does a whole-home HEPA filter integrate with my existing heating and air conditioning equipment?
For most homes we install the HEPA unit as a bypass filter connected to your return-air ductwork. About 20 % of the air leaving the air handler is diverted through the sealed HEPA cabinet, filtered, then routed back into the supply plenum. This design avoids major pressure drops, protects the blower motor, and works with virtually any forced-air furnace, heat pump, or packaged unit common in Walland homes. No additional thermostats are needed; the filter runs whenever your HVAC fan operates.
Will adding a HEPA filter restrict airflow or drive up energy costs?
Because the HEPA media is housed in its own powered cabinet, it creates minimal resistance to your main HVAC airflow. The fan motor inside the HEPA unit handles the pressure needed to push air through the dense filter, so your existing blower is not overworked. Customers typically see no noticeable change in utility bills, and many actually save money by running their HVAC fan in continuous low-speed mode and letting the HEPA unit maintain air quality rather than opening windows.
How often should I replace or service my HEPA filter in Walland’s climate?
Under average operating conditions the primary HEPA cartridge lasts 2–3 years, while the pre-filters (which capture larger dust and lint) should be changed every 6–12 months. In Walland’s high-pollen spring and leaf-drop autumn seasons, you may need to inspect pre-filters more frequently. Our maintenance plans include reminders and discounted filter media, and a technician can change the filter during your routine HVAC tune-up.
Can a HEPA system remove viruses, odors, and volatile organic compounds (VOCs)?
The HEPA media excels at trapping tiny biological particles, including many bacteria and viral aerosols. For odors and chemical gases, we pair the HEPA stage with an activated carbon or photocatalytic module that adsorbs VOCs from household cleaners, cooking, and smoke. This dual-stage approach delivers comprehensive indoor air purification, making your home safer during cold-and-flu season and more pleasant when windows are closed.
What does installation cost and how long does it take in the Walland area?
Most whole-home HEPA installations fall between $1,200 and $2,000, depending on duct accessibility and whether additional odor-control stages are added. Labor takes roughly 3–4 hours, so we can complete the job in a single visit. Residents of Blount County may qualify for utility rebates or special financing through our HVAC partner programs.
