FAQs

1. What exactly is a whole-home ventilator and how is it different from bathroom or kitchen exhaust fans?

A whole-home ventilator is a dedicated piece of equipment—usually an Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV)—that is tied into your central heating and air‐conditioning ductwork. Instead of removing air from only one room like a spot exhaust fan, it brings in measured amounts of fresh outdoor air, filters it, conditions it for temperature and humidity, and distributes it throughout the entire house while simultaneously exhausting stale indoor air. This balanced exchange helps control odors, moisture, and airborne pollutants everywhere in the home, not just in isolated areas.

2. Why is mechanical ventilation so important for homes in Etowah?

Etowah’s climate features hot, humid summers, mild winters, and an above-average pollen count in spring and fall. Modern homes are built tighter for energy efficiency, which means outdoor air infiltration is minimal. Without mechanical ventilation, moisture builds up, leading to mold growth, dust-mite proliferation, musty odors, and indoor pollutant concentrations that can be two to five times higher than outdoors. A whole-home ventilator ensures you get the fresh air exchange you need without relying on leaky windows or doors, improving comfort and protecting the structure of your home.

3. Will adding a whole-home ventilator raise my utility bills?

While any device that moves air uses some electricity, properly sized ERVs and HRVs are designed to minimize energy impact. An HRV transfers heat between outgoing and incoming air streams, and an ERV transfers both heat and moisture. In Etowah’s humid climate, an ERV is often recommended because it helps keep excess moisture out of the living space, reducing the load on your air conditioner. The result is just pennies a day in operating costs and, in many cases, a net reduction in HVAC runtime because balanced ventilation prevents the humidity spikes that force your AC to cycle on more often.

4. Which type of whole-home ventilator—ERV or HRV—should I choose for Etowah, and how do I know what size I need?

For East Tennessee’s humidity profile, an ERV is generally preferred because it moderates both heat and moisture transfer, helping to keep indoor relative humidity in the ideal 40–60 % range year-round. HRVs are more common in colder, dryer climates. Sizing is based on your home’s square footage, ceiling height, the number of occupants, and the building’s airtightness. Industry guidelines (ASHRAE Standard 62.2) recommend roughly 1 CFM (cubic foot per minute) of fresh air per 100 sq ft of floor area plus 7.5 CFM per person. Our technicians perform a ventilation load calculation to select a model that meets code requirements without oversizing, which could waste energy.

5. Where is the equipment installed and how loud is it?

The ventilator cabinet is usually mounted in the attic, crawl space, or mechanical room—wherever it can easily connect to your supply and return ducts. Flexible, insulated duct runs carry fresh air to the HVAC supply plenum and stale air back from bathrooms or other moisture-prone areas. Modern ERVs/HRVs use variable-speed, ECM blower motors and acoustic insulation, keeping sound levels in the 0.5–1.0 sone range—about as quiet as a whisper. Most homeowners never notice when the unit cycles on.

6. What maintenance is required and can I do it myself?

Routine maintenance is simple and can extend the life of the unit well past 15 years. 1) Inspect and replace or wash the ventilator’s air filters every 3–6 months—more often during Etowah’s high-pollen seasons. 2) Clean the core (the heat- or energy-transfer matrix) yearly with a vacuum or mild soap solution, following the manufacturer’s instructions. 3) Make sure the exterior intake and exhaust hoods are free of leaves, lint, or insect nests. 4) During your annual HVAC tune-up, let our technician verify airflow balances and check the condensate drain for clogs. Most homeowners are comfortable handling the filter changes, but we can include all of these tasks in our affordable maintenance plan if you prefer a hands-off approach.
