House grills closed or blocked

Dampers are closed if installed

Poor power supply at site

Ductwork is restricting HRV

Improper speed control setting

HRV airflow improperly
balanced

Clean exterior hoods or vents

Remove and clean filter

Remove and clean core

Check and open grilles

Open and adjust dampers

Have electrician check supply voltage

Check duct installation

Increase the speed of the HRV

Have contractor balance HRV
Supply air feels cold

Outdoor temperature
extremely cold

Turn down the HRV supply speed

Placement of furniture or closed doors is
restricting the movement of air in the
home

If supply air is ducted into furnace return,
the furnace fan may need to run
continuously to distribute ventilation air
comfortably
Dehumidistat in not

15
o
C (59
o
F)

Check dehumidistat setting it
may be on OFF


Lifestyle of the occupants

Moisture coming into the home

homes air quality will remain high with
some HRV use

Increase speed of the HRV
Humidity levels are too
low

Dehumidistat control set too
low

Blower speed of HRV is too
high

Lifestyle of occupants

HRV airflows may be
improperly balanced

Set dehumidistat higher

Decrease HRV blower speed

Humidity may have to be added through
the use of humidifiers

Have contractor balance HRV airflows
HRV and/or ducts frosting
up

HRV airflows are improperly
balanced

Malfunction of the HRV defrost
system

Note: minimal frost build-up is expected
on cores before unit initiates defrost cycle
functions

Have HVAC contractor balance the HRV
Condensation or ice build
up in insulated duct to
the outside

Incomplete vapor barrier
around insulated duct

A hole or tear in outer duct
covering

Tape and seal all joints

Tape any holes or tears made in the outer
duct covering, ensure that the vapor
barrier is completely sealed
Excess water in the bot-
tom of the HRV

Drain pans plugged

Improper connection of HRV’s
drain lines

HRV is not level

Drain lines are obstructed



Look for obstructions in the drain line

