ERV Installation in Atlanta, GA: Fresh Air Ventilation

Looking for ERV Installation in Atlanta? A tight, well-sealed home saves energy, but it can also trap stale air, moisture and indoor pollutants. An energy recovery ventilator, or ERV, brings fresh outdoor air in while sending stale indoor air out, and it passes heat and moisture between the two streams so the fresh air arrives closer to indoor conditions. Pure Air Atlanta installs ERV systems for Atlanta homes, condos and small buildings that need controlled fresh air.

How an ERV works

An ERV has two airstreams that pass through a core without mixing. In summer the outgoing air cools and dries the incoming air a little. In winter it warms the incoming air. Because it also transfers moisture, an ERV is generally favored in climates like Atlanta's, where summers are hot and humid, since it helps keep that humid outdoor air from becoming a bigger load on your air conditioner. The US Department of Energy gives an overview of ventilation options on its HVAC whole-house ventilation page.

ERV or HRV?

A heat recovery ventilator, or HRV, moves heat but not moisture. HRVs suit cold, dry climates. For most Atlanta homes an ERV is the better fit, but the right choice depends on the house, so we look at how the house is built before recommending one.

Who benefits from an ERV

• Newer homes and renovated houses that were air-sealed or insulated with spray foam
• Condos and high-rise units with little natural air exchange
• Homes where windows stay closed for most of the year, because of pollen, noise or humidity
• Households with allergies who want filtered fresh air, which can pair with air purification
• Homes with a lingering stale smell or condensation on windows

How we install an ERV

1. Assessment. We look at the layout, the existing HVAC and where the unit can go: an attic, closet or utility space.
2. Design. We choose between tying into the existing ducts and running separate ducts for fresh air and exhaust.
3. Installation. We mount the unit, run the ducts, install the outdoor intake and exhaust vents, wire the controls and seal the connections.
4. Balancing and controls. We set the airflow and show you the fan speeds, timers and any humidity controls.

New ventilation equipment and duct changes can require a permit. The City of Atlanta explains how to start on its permitting services page.

ERV maintenance

Filters need cleaning or replacing on the schedule in the manual, and the core is usually rinsed or vacuumed once or twice a year. Keep the outdoor vents clear of leaves. If the ducts have not been cleaned in years, air duct cleaning is a good companion service.

ERV Installation FAQ

Do I need an ERV?

Not every home does. It makes the most sense in a tight house, a condo with little air exchange, or a home where fresh air is a problem. We can tell you after we look at the house.

Does an ERV replace my air conditioner?

No. An ERV only brings in fresh air and exhausts stale air. Your HVAC system still heats and cools the house.

Will an ERV add humidity?

An ERV passes some moisture between the airstreams, but it is designed to reduce the humidity load from outdoor air compared with simple fresh-air vents. Correct sizing and settings matter.

Can an ERV be added to an existing house?

In many cases, yes, depending on space and the existing ducts. We check the layout before recommending a design.

How much does ERV installation cost?

The cost depends on the unit, the ducting and the access. Our pricing page explains how we quote.
