FAQs
What is a whole-home HEPA filtration system and how does it work with my existing HVAC equipment in Greenback?
A whole-home HEPA (High-Efficiency Particulate Air) filtration system is an add-on cabinet that houses a true HEPA filter and a high-output, sealed bypass fan. The cabinet is installed in the return-air plenum of your central heating and air-conditioning ductwork. Roughly 20–30% of the air is diverted through the HEPA filter where 99.97% of particles down to 0.3 microns are removed before the air rejoins the main airstream and is delivered to the supply ducts. Because it integrates with your existing furnace or air-handler blower, every time the HVAC system runs—or when the filtration fan is set to continuous—your entire home’s air is cleaned rather than just a single room.
Why is HEPA filtration important for indoor air quality in the Greenback area?
Greenback’s tree pollen peaks in spring, ragweed counts rise in late summer, and our mild winters mean more time indoors where dust, pet dander, and airborne viruses can accumulate. A true HEPA filter captures ultrafine particles, allergens, mold spores, bacteria, and some viruses that standard 1-inch HVAC filters miss. By reducing these contaminants, whole-home HEPA systems help alleviate allergy and asthma symptoms, lower the risk of respiratory infections, and create a healthier living environment year-round for Greenback residents.
Will adding a whole-home HEPA unit increase my energy bills?
The dedicated bypass fan inside the HEPA cabinet uses about the same electricity as a 60-watt light bulb. Because the system is sealed and sized for your ductwork, it adds negligible static pressure, so your furnace blower does not have to work harder. Most homeowners in Greenback notice only a $3–$5 per month increase on their electric bill—often offset by fewer doctor visits and lower spending on portable air cleaners.
How often do HEPA filters need to be replaced and what maintenance is required?
In an average Greenback household, the pre-filter should be changed every 6 months to capture larger dust and hair. The activated-carbon VOC filter is typically replaced once a year to keep odors and chemical vapors in check. The true HEPA filter lasts 2–3 years, depending on run-time and indoor pollution levels. Our technicians perform a quick pressure-drop test at each maintenance visit to tell you exactly when the HEPA core needs swapping, ensuring optimal airflow and efficiency.
Can a whole-home HEPA system eliminate the need for portable air purifiers?
Yes, in most cases. Because the HEPA unit treats the entire air volume of your home multiple times per day, it provides uniform, consistent filtration in every conditioned room. This means you no longer have to buy, maintain, or listen to the noise of several portable units. Some clients still keep a small purifier in high-pollution zones like workshops or nurseries, but for general living spaces, the whole-home system is more effective and convenient.
What is involved in the installation process and how long does it take?
A certified technician will perform a 30-minute duct assessment to locate the optimal bypass location, usually near the return plenum. Installation involves cutting a small opening in the duct, mounting the insulated HEPA cabinet, running a short bypass duct, and wiring the fan to your HVAC control board or a dedicated switch. No structural changes to your home are needed. Most installations in Greenback are completed in 4–6 hours, and you can run your heating or cooling system the same day. Our team will also show you how to access the filter compartment and program your thermostat for maximum air-cleaning cycles.
