FAQs
What is an Energy Recovery Ventilator (ERV) and how does it improve indoor air quality?
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 winter, the ERV captures heat and some humidity from outgoing air and pre-warms the incoming fresh air. In summer, it reverses the process, expelling heat and excess humidity before the fresh air enters your ducts. This continuous, balanced airflow removes pollutants, odors, and excess CO₂, giving your Harrison home cleaner, healthier air without the large energy penalty of simply opening windows.
How do ERVs contribute to energy efficiency in Harrison’s four-season climate?
Because Harrison experiences hot, humid summers and cold winters, ventilation normally imposes a heavy heating or cooling load. An ERV can recover 60–80 % of the heat (or cooling) that would otherwise be exhausted. That means your furnace or air conditioner doesn’t have to work as hard, reducing annual energy consumption by 10–25 % depending on house tightness and usage. The moisture exchange also keeps indoor relative humidity in the 30–50 % sweet spot, allowing you to set the thermostat a few degrees higher in summer and lower in winter without sacrificing comfort.
Can an ERV be integrated with my existing HVAC system?
Yes. Most ERVs are designed to tie into the supply and return plenums of a conventional forced-air system, so the fresh air distributes evenly through your ductwork. If you use ductless mini-splits or hydronic heat, a dedicated ERV duct run or compact, room-based ERV is an option. A licensed HVAC contractor will size the unit based on square footage and occupant load, ensure proper airflow balancing, and connect the ERV controls to your thermostat or a stand-alone timer for seamless operation.
What maintenance does an ERV require and how often?
Routine care is straightforward: (1) Inspect and vacuum or replace the intake and exhaust filters every 3 months—more often during pollen season in Harrison. (2) Clean the core or wheel—where heat and moisture transfer occurs—about once a year with mild soap and water. (3) Check the condensate drain every spring to prevent clogs. (4) Have a professional perform an airflow and controls check annually. Following these steps keeps efficiency high and prevents mold growth inside the unit.
Are ERVs suitable for both new construction and retrofits in Harrison?
Absolutely. Building codes for new homes already require mechanical ventilation, and an ERV satisfies that requirement while saving energy. For existing homes, an ERV can be retrofitted with minimal disruption: installers usually add two 6-inch exterior wall penetrations for fresh air intake and stale air exhaust and tap into existing ducts. In older houses that leak more air, the ERV pairs well with air-sealing upgrades, ensuring you get fresh air without unwanted drafts.
How does installing an ERV qualify for local rebates or incentives?
New York’s NYSERDA and many utility programs serving Westchester County, including Con Edison, periodically offer rebates for ENERGY STAR-certified ventilation equipment. Incentives can cover $300–$700 of the installed cost, especially when bundled with insulation or heat-pump projects. Federal tax credits under the Inflation Reduction Act may also apply, providing up to 30 % of the cost (maximum $600 for qualified HVAC components). Your HVAC contractor can supply model numbers and efficiency ratings to include with your rebate application and handle any necessary airflow verification paperwork.
