FAQs
What is a HEPA filter and how does it improve indoor air quality in Farragut homes?
HEPA (High-Efficiency Particulate Air) filters are rated to remove at least 99.97 % of airborne particles down to 0.3 microns, including pollen, mold spores, pet dander, and some bacteria and viruses. In Farragut, seasonal pollen counts are high and humidity encourages mold growth, so a HEPA-equipped HVAC or whole-house air purifier can dramatically reduce allergy and asthma triggers while providing cleaner, healthier air throughout your living space.
Can a HEPA filtration system be added to my existing heating and air-conditioning equipment?
Yes. Most modern forced-air systems can be upgraded with a HEPA bypass or in-line filtration cabinet. Our technicians evaluate your duct size, blower capacity, and static-pressure tolerance to choose the right configuration. When space is limited, we often install a dedicated HEPA air purifier that ties into the supply plenum, filtering the air without over-restricting airflow. A quick on-site assessment lets us confirm compatibility and provide an accurate cost estimate.
How often should I replace or service my HEPA filter?
In a typical Farragut household, the main HEPA cartridge lasts 12–24 months, while any pre-filters or carbon filters should be changed every 3–6 months. Homes with pets, smokers, ongoing construction, or family members with respiratory issues may need more frequent replacement. We recommend scheduling biannual maintenance so our team can inspect pressure differentials, change pre-filters, and verify the integrity of the HEPA seal to maintain peak performance.
Will a HEPA filter increase my energy bills or strain my HVAC system?
A properly designed HEPA upgrade has only a modest impact on energy use—usually less than 5 %—because the filter is installed in a bypass loop or accompanied by a high-efficiency, variable-speed blower that compensates for added resistance. Skipping a professional load calculation or using an undersized fan can raise static pressure and reduce efficiency, so expert installation is the key to keeping operating costs low while still achieving hospital-grade filtration.
Is HEPA filtration effective against viruses such as COVID-19 in indoor environments?
HEPA filters capture respiratory droplets and aerosols in the 0.1–1 micron range that can carry viruses, including SARS-CoV-2. While no single technology can guarantee complete protection, combining HEPA filtration with adequate ventilation, proper humidity control (40–60 %), UV-C or bipolar ionization, and routine surface disinfection creates a layered defense that significantly reduces airborne transmission risks in homes, offices, and medical or childcare facilities.
What professional services do you offer to keep my HEPA and HVAC systems running optimally?
Our Farragut team provides: 1) system design and installation for HEPA bypass or whole-house purifiers; 2) routine filter replacements with OEM-approved media; 3) airflow and static-pressure testing; 4) duct sealing and cleaning to minimize dust load; 5) smart-thermostat and variable-speed blower upgrades; and 6) 24/7 emergency service for heating and cooling breakdowns. We also offer indoor air-quality assessments with particle counts and CO₂ monitoring to verify the results of your HEPA system.
