What ERV means
An ERV is an energy recovery ventilator: a balanced fan unit that brings in fresh air and exhausts stale air while passing heat, and some moisture, between the two streams.
Also called energy recovery ventilator, HRV.
Where it matters on a HVAC job
Tight new houses often need mechanical ventilation, and an ERV or HRV is the comfortable way to provide it. It needs its own ducts and filter changes, which belong in the maintenance plan.
What it costs
Jobs that involve ERV are priced in the hVAC maintenance cost guide: about $190 typical, usually $100 to $280. The guide shows its sources and what moves the price.
