Cause

• Mesh on outside hood is plugged
• Filters plugged
• Cores obstructed

• House grilles closed
• Dampers closed
• Low voltage at site
• Ductwork too long, excessive number of bends
• Improper speed control setting
• Improper balancing of ERV airflows

• Poor location of air supply grilles, cause 

discomfort

• Outdoor temperature below 25°F (-4°C)

• Excessive infiltration through house leakage

• ERV speed set too high
• Dehumidistat set too low
• ERV improperly balanced
• Lifestyle of occupants, generate little indoor

humidity

• Dehumidistat is set too high
• ERV speed set too low
• ERV not operating continuously
• Presence of strong sources of moisture: indoor

pool, hot tub, unvented crawl space

• Improper connection
• Wiring to remote dehumidistat may have been

damaged by staple or nail

• Dehumidistat may be turned off

• ERV operating at too low speed
• ERV not properly balanced
• ERV undersized, allowing indoor humidity to rise

• Incomplete vapor barrier on insulated duct
• Tear or hole in vapor barrier on insulated duct

TROUBLESHOOTING YOUR ERV SYSTEM

Symptom

Poor air flow

Supply air inlet feels cold (a 
problem if it affects the 
occupant in the normal living 
environment, not just cold air 
at the supply grille itself

Humidity levels are too low

Humidity levels are too high

Dehumidistat not working

ERV or ducts to indoors frosting

Condensation or frost in insulated
duct to exterior

Solution

• Clean exterior hoods or vents
• Remove and clean filters
• Remove and clean core (vacuum or blow out;

do not wash)

• Open and adjust grilles
• Open and adjust dampers
• Have electrician check voltage
• Have HVAC contractor check ducting
• Increase speed setting
• Have HVAC contractor re-balance system

• Relocate air supply grilles so airflow does not

affect occupant. Adjust grille so that airflow is
entrained along wall or ceiling. (Note, closing the
grille too far will cause the air to be directed
downward from a ceiling, rather than along the
ceiling.

• A small duct heater may be added to the supply

air ducting to boost temperature. If supply air is
ducted to the furnace return, the furnace fan may
not need to run at low speed continuously.

• Weather-strip, caulk and seal opening through

wall, ceiling, at doors and windows to the 
exterior.

• Lower ERV speed setting.
• Set dehumidistat higher.
• Have HVAC contractor re-balance system.
• May need to install a humidifier.

• Lower dehumidistat setting.
• Set ERV speed higher.
• Operate ERV continuously.
• Maintain cover on pool, hot tub when not in use.

Note: an ERV is not designed to provide 
dehumidification of indoor pools, etc.

• Consider an HRV instead.
• May need to install and/or operate additional

exhaust fans for use in kitchens and baths for
short durations.

• Check that correct terminals have bee used.
• Check wiring for a short.

• Set dehumidistat to desired level.

• Set ERV to higher speed
• Have HVAC contractor re-balance system.
• Add additional ventilation, or change to HRV,

ERV recommended for regions where the 
temperature does not drop below -4°C (25°F).

• Replace or repair tears, holes in vapor barrier,

tape all joints in outer covering
