FAQs
What is an energy-recovery ventilator (ERV) and how does it improve indoor air quality in Greenback homes?
An ERV is a mechanical ventilation device that exchanges stale indoor air with fresh outdoor air while transferring heat and moisture between the two airstreams. In humid summers and cool winters typical of Greenback, the ERV pre-conditions the incoming air—removing excess humidity in summer and retaining heat and moisture in winter—so your HVAC system works less. The result is a continuous supply of fresh air, reduced pollutants such as VOCs, and balanced indoor humidity, all of which contribute to healthier indoor air quality without large energy penalties.
How does installing an ERV affect my heating and cooling energy bills?
Unlike a standard exhaust fan that simply dumps conditioned air outside, an ERV recovers 60–80 % of the heat and moisture that would otherwise be lost. In Greenback’s mixed-humid climate, that typically translates to HVAC energy savings of 10–25 %. Because the ERV tempers the incoming air, your air conditioner and furnace run fewer and shorter cycles, lowering electricity and fuel consumption while still delivering fresh air year-round.
Can an ERV be added to my existing HVAC system, or do I need a full replacement?
Most homes and small commercial buildings in Greenback can retrofit an ERV into the existing ductwork. We perform a load calculation to size the unit, identify a suitable location (often near the air handler or in the attic), and tie the ERV’s dedicated supply and return ducts into the main system. Controls can be integrated with your thermostat or operate on a timer. A full HVAC replacement isn’t usually necessary unless we discover undersized ducts or very old, inefficient equipment, in which case upgrading both may provide the best efficiency and comfort gains.
What maintenance does an ERV require and how often?
ERV maintenance is straightforward. 1) Replace or wash the intake and exhaust filters every 3–4 months—more often during Greenback’s pollen season. 2) Inspect and clean the core annually; our technicians remove debris and check for mold growth. 3) Ensure the condensate drain is clear so humidity can exit the system. During a yearly HVAC service visit, we also verify fan operation, balance airflow, and confirm that controls are set for the correct ventilation rate per ASHRAE 62.2 guidelines.
How noisy is an ERV compared with other ventilation options?
Modern ERVs are engineered with insulated cabinets, variable-speed ECM motors, and rubber isolation mounts, resulting in sound levels as low as 0.5–1.5 sones—quieter than a typical bathroom exhaust fan. Because the unit is usually installed in an attic, crawlspace, or mechanical closet, occupants in Greenback homes rarely notice any operational noise. For extra sensitivity, we can add duct silencers or flexible connectors to further reduce sound transmission.
Is an ERV suitable for homes with allergies or respiratory sensitivities?
Yes. ERVs continuously replace indoor air that may contain allergens, pet dander, or chemical pollutants with filtered outdoor air. By controlling humidity, they also reduce dust mite and mold growth. For households in Greenback with severe allergies, we can upgrade to MERV 13 or higher filters and add a HEPA bypass box. Combined with proper source control and regular cleaning, an ERV becomes a key component in a holistic indoor air quality strategy.
