FAQs
What indoor air quality (IAQ) problems are most common in Walland, TN, and how can my HVAC system help?
Because Walland sits in a valley surrounded by forests, we see high pollen counts in spring, elevated humidity in summer, and smoke or wood-burning particulates in winter. When windows stay closed to conserve energy, these contaminants build up indoors. A properly configured HVAC system—with the right filtration, sealed ductwork, balanced ventilation, and regular maintenance—captures allergens, dilutes volatile organic compounds (VOCs), and keeps humidity in the ideal 30–50 % range so mold and dust mites cannot thrive.
How often should I replace or upgrade my air filters?
For most homes in Walland we recommend replacing a standard 1-inch pleated filter every 60–90 days. If you own pets, suffer from allergies, or live close to open fields or construction sites, change it every 30 days. High-efficiency media filters (4–5 inch) last 6–12 months. Smart thermostats can remind you automatically, and our maintenance plans include scheduled filter changes so you never have to remember.
What air-cleaning add-ons do you install and how do they work?
• High-MERV/HEPA media cabinets physically trap 99.97 % of particles down to 0.3 µm. • UV-C germicidal lamps sit in the air handler and break down the DNA of bacteria, viruses, and mold spores so they cannot reproduce. • Bipolar ionizers send charged ions through your ductwork; these ions cause tiny particles to clump together, making them large enough for the filter to catch. • Activated-carbon panels adsorb odors and chemical fumes. We match equipment to the size of your system so airflow and static pressure stay within manufacturer specs.
Can better ventilation really reduce humidity and mold risk in our humid summers?
Yes. A dedicated fresh-air intake or an energy-recovery ventilator (ERV) exhausts stale indoor air while bringing in filtered outdoor air. In the process, it transfers excess moisture to the outgoing airstream, so the incoming air is cooler and drier. This keeps indoor relative humidity below 50 % even on muggy July days, cutting mold risk dramatically without overworking your air conditioner.
How do energy-recovery ventilators (ERVs) and heat-recovery ventilators (HRVs) improve both air quality and efficiency?
ERVs and HRVs draw in outdoor air and expel stale indoor air through a heat-exchange core. In summer they transfer heat and some moisture from the incoming air to the outgoing air; in winter they reclaim heat from the exhaust air to pre-warm the fresh air. You get continuous ventilation without sacrificing comfort or increasing utility bills. The result is cleaner, fresher air, reduced CO₂ levels, and less strain on your HVAC equipment.
What ongoing services do you provide to keep my system delivering clean air year-round?
Our IAQ maintenance packages include: • Bi-annual HVAC tune-ups (spring and fall) checking refrigerant, airflow, and duct integrity. • Filter replacement or media wash service on the schedule that fits your home. • UV-lamp and ionizer bulb inspections and replacement. • Duct cleaning and sanitizing every 3–5 years or as needed. • Humidity calibration and ERV/HRV core cleaning. • Detailed IAQ reports with particulate and VOC readings so you can track improvements over time.
