FAQs
Why is indoor air quality (IAQ) an important issue in Tullahoma and Middle Tennessee?
Tullahoma’s humid subtropical climate encourages mold, pollen, and dust-mite growth nearly year-round. Because we often keep our homes tightly closed to run the air-conditioner in summer and the furnace in winter, these contaminants become trapped indoors. The EPA estimates indoor air can be two to five times more polluted than outdoor air. Poor IAQ can aggravate allergies, asthma, and other respiratory problems, so addressing it is essential for health and comfort in this region.
What pollutants are most common in homes and businesses here, and how do they enter the air?
The most frequently detected pollutants in Tullahoma properties include: • Pollen from oak, ragweed, and grasses that infiltrates through open doors and windows. • Mold spores that thrive in our moist summer climate and multiply in damp basements, crawl spaces, or HVAC systems. • Volatile organic compounds (VOCs) released by cleaning products, paint, and new furnishings. • Dust and dust-mite debris that accumulate in carpeting and ducts. • Combustion byproducts such as carbon monoxide or nitrogen dioxide from gas appliances if they are not vented properly. • Pet dander from cats and dogs. Once inside, these pollutants recirculate through the HVAC system unless they are filtered out or diluted with fresh air.
How can my HVAC system be upgraded to improve indoor air quality?
Modern HVAC add-ons provide multiple layers of protection: 1. High-efficiency filters (MERV 11–16) capture fine dust, pollen, and dander better than standard filters. 2. Electronic air cleaners or HEPA bypass units physically remove 99.97 % of particles down to 0.3 µm. 3. UV-C germicidal lights installed in the air handler neutralize mold spores, bacteria, and some viruses as air passes by. 4. Whole-home air purifiers with activated carbon reduce odors and VOCs. 5. Energy-recovery ventilators (ERVs) bring in fresh outdoor air while transferring heat and humidity to maintain efficiency. A licensed HVAC technician can test your home, size the equipment correctly, and integrate these options without overloading your existing system.
Do I need a dehumidifier in Tullahoma’s humid climate, and will it affect my energy bills?
Many homes here benefit from a whole-house dehumidifier because summer humidity regularly exceeds 60 %. High indoor moisture promotes mold, musty odors, wood warping, and that sticky, uncomfortable feeling even when the thermostat says 72 °F. A dehumidifier keeps relative humidity between 40–50 %, which reduces biological growth and helps you feel cooler at a slightly higher thermostat setting. This often lowers AC runtime, saving electricity and offsetting the dehumidifier’s cost. Because the unit ties into your HVAC ductwork, it operates quietly and drains automatically.
How often should I replace or clean my HVAC filter, and what MERV rating is best for allergy sufferers?
In Tullahoma, where pollen peaks in spring and fall, check your filter monthly and replace it at least every 60 days (30 days if you have pets or allergies). A MERV 11 filter balances airflow and filtration for most homes. Allergy and asthma sufferers may upgrade to MERV 13–16 or a true HEPA cabinet filter, but higher resistance filters require a system inspection to confirm your blower can handle the added pressure without reducing airflow or efficiency.
Can better ventilation really reduce energy bills and improve comfort?
Yes. Stale, humid indoor air forces the AC to work harder and makes occupants feel sluggish. An ERV or HRV (heat- or energy-recovery ventilator) introduces filtered outdoor air while reclaiming up to 80 % of the heat and humidity difference between the airstreams. This exchange dilutes indoor pollutants, reduces excess moisture, and lessens your reliance on heating or cooling to maintain comfort. Properly engineered ventilation can cut annual energy costs by 10–20 % compared with opening windows or relying solely on exhaust fans.
