FAQs
Why is indoor air quality so important for homes and businesses in Collegedale’s humid climate?
Collegedale’s warm, humid summers and mild, damp winters create an environment where mold, dust mites, and airborne allergens thrive. Because we spend up to 90 % of our time indoors, pollutants become concentrated and can aggravate asthma, allergies, and other respiratory issues. Properly designed HVAC and ventilation systems dilute contaminants, control humidity, and continuously filter the air, helping protect your family’s health, reducing odors, and even extending the life of furnishings and electronics.
What contaminants are most common in Collegedale homes, and how can my HVAC system remove them?
Typical indoor pollutants include pollen from the Tennessee Valley, fine dust from nearby construction or agriculture, pet dander, volatile organic compounds (VOCs) released from cleaning products and new furnishings, and mold spores that flourish in our moist climate. A high-efficiency HVAC setup combats these by combining a pleated MERV-rated filter to trap particles, an optional activated-carbon stage to adsorb VOCs and odors, and balanced ventilation that exhausts stale air while bringing in filtered, conditioned outdoor air.
How often should I replace or upgrade my HVAC air filter?
For standard 1-inch filters, we recommend replacement every 30–60 days in Collegedale, where pollen counts are high for much of the year. Thicker 4- to 5-inch media filters usually last 6–12 months. If you have pets, allergies, or recent construction dust, check more frequently. Upgrading to a higher MERV rating (MERV 11–13) captures smaller particles without stressing most modern systems; just confirm with a technician that your blower motor can handle the added resistance.
What is a whole-home ventilation system, and why is it better than simply opening windows?
A mechanical ventilation system—such as an energy-recovery ventilator (ERV) or heat-recovery ventilator (HRV)—removes stale indoor air and supplies fresh outdoor air through dedicated ductwork while transferring heat and, in an ERV, humidity. This allows continuous air exchange without the security risks, temperature swings, and pollen influx that come from cracking windows. In Collegedale’s humid summers, an ERV also limits moisture gain so your air conditioner doesn’t have to work as hard.
Can I add air-cleaning upgrades like UV lights or electronic air cleaners to my existing heating and cooling equipment?
Yes. Most systems can be retrofitted with germicidal UV-C lamps installed in the air handler or over the evaporator coil to inhibit mold and bacteria growth. Electronic air cleaners, plasma generators, or in-duct ionizers can target ultra-fine particles and some pathogens. A professional will verify there ’s enough space, ensure electrical compatibility, and confirm the add-on won’t create harmful ozone. Combining these technologies with high-MERV filtration and proper duct sealing yields the best results.
How can I tell if my HVAC system is hurting my air quality, and when should I schedule a service call?
Warning signs include persistent dust buildup, musty or chemical odors, new or worsening allergy symptoms, condensation on windows, and uneven humidity levels. If your energy bills rise or you hear unusual fan noise, restricted airflow may be circulating contaminants. Schedule a professional inspection at least once a year—ideally before summer—to check filter condition, duct cleanliness, refrigerant levels, and ventilation balance. Technicians can perform an indoor air quality assessment, measure particulate counts, and recommend targeted improvements.
