Scale on the pad or wick, a failed water valve or a bad humidistat.
Purifier or ventilator not moving air
Clogged filters, a failed fan motor or a control fault.
Thermostat not controlling the system
Dead batteries, a wiring fault or a failed thermostat.

Low refrigerant, a failed compressor relay, an iced coil or a room that is too cold.

Should I repair or replace my erv?
A erv typically lasts about 5 to 15 years. If yours is well inside that range and the repair costs less than half the price of a new one, repairing usually makes sense. Near the end of its life, or when the repair costs more than half of a replacement, replacing is often the better value. We give you an honest opinion either way.
