FAQs
Why is mold growth a common problem in HVAC systems and ductwork around South Pittsburg, TN?
Our area sits in the humid Tennessee River valley, so outdoor relative humidity frequently climbs above 70 %. When warm, moist air leaks into cool ductwork or un-conditioned crawl spaces it condenses on metal surfaces and fiberglass insulation, creating an ideal breeding ground for mold spores. Because HVAC systems circulate air throughout the entire home, any mold that forms in one section can quickly spread, aggravating allergies and reducing indoor air quality.
How does a whole-home dehumidifier stop mold from forming?
Mold needs two things to thrive—moisture and organic material. A properly sized dehumidifier integrates with your HVAC return plenum and automatically maintains indoor relative humidity between 40 % and 50 %, a range in which most mold species cannot reproduce. By removing excess moisture before it settles on walls, carpet, or duct liners, the unit starves mold of the water it needs and keeps spores from colonizing surfaces.
Will running a dehumidifier increase my utility bills?
A dehumidifier does consume electricity, but many homeowners see little or no net increase in utility costs. When indoor humidity is controlled, your air conditioner doesn’t have to work as hard to remove latent heat, so run-times shorten and cooling bills drop. In addition, modern ENERGY STAR®-rated dehumidifiers use variable-speed compressors and draw roughly the same power as a small window AC, often adding only $10–$15 per month in South Pittsburg’s peak summer season.
What size dehumidifier do I need for my house?
Sizing is based on square footage, ceiling height, insulation levels, and the amount of moisture you routinely generate through cooking, showers, or basement seepage. During our in-home assessment we perform a Manual J moisture load calculation and use manufacturer charts to match your conditions to the correct pint-per-day capacity. For most South Pittsburg residences, capacities between 70 and 120 pints per day are typical, while larger heritage homes or properties with finished basements may require 150-plus-pint commercial units.
How much maintenance does a whole-home dehumidifier require?
Minimal upkeep is needed. The disposable air filter should be checked every three to six months and replaced when dirty to keep airflow unrestricted. The condensate line must remain clear so water drains to the sump or outdoors; we flush it during your annual HVAC tune-up. Most units also have a washable MERV-8 pre-filter or coil that should be cleaned once a year to maintain efficiency.
Can I install a dehumidifier myself, or should I hire a licensed HVAC contractor?
Whole-home units connect directly to the return duct, require a dedicated 120 V or 240 V circuit, and must be leveled and pitched for proper drainage, so professional installation is highly recommended. Tennessee state law calls for a licensed mechanical contractor to perform any work that modifies existing HVAC systems. Using a certified installer also preserves the manufacturer’s 5- or 10-year warranty and ensures the unit is set up to meet local building and plumbing codes in South Pittsburg.
