7. Arrange for annual servicing. Your HRV should undergo

annual general servicing by a contractor who is accredited by

the Heating, Refrigeration and Air Conditioning Institute of

Canada (HRAI) and is familiar with your HRV. If possible,

have your furnace and HRV serviced at the same time. This

service will result in less inconvenience and cost less than two

separate visits.

The HRV’s annual servicing should include the following:

 • maintenance items 1 to 6 (above) and any additional

requirements speciﬁed by the manufacturer;

 • a general check for proper operation. Controls and

electrical connections in the HRV should be inspected,

particularly those located inside the exhaust and fresh air

streams. The defrost system should also be tested;

 • veriﬁcation that the intake and exhaust airﬂows are

properly balanced. Actual airﬂows should be measured

and the results should be indicated on the maintenance

label afﬁxed to the HRV. If necessary, the airﬂows should be

rebalanced.

The contractor should provide you with a written report on the

HRV’s overall condition. Before requesting such a report, ask

whether an extra fee will be charged.

To help you remember when maintenance is due, an HRV

Maintenance Chart is provided on the next page. Post a copy

on the HRV to keep a record of your service and maintenance

schedule.
