Furnace Tune-Ups & Maintenance in Winnipeg, MB

Diagram: buy the size printed on the filter edge, and install it with the airflow arrow pointing toward the furnace.

Venting

The technician checks vent pipes for damage, proper slope and clearances from snow and windows.

Carbon monoxide

A tune-up includes checking for safe combustion. Keep working CO alarms on every level.

Humidifier and HRV

Change humidifier pads and clean HRV filters at the same visit.

Timing

September and October are ideal, before the first cold snap fills technicians' schedules.

Warranties

Some manufacturers require regular maintenance. Keep records.

Book a tune-up

Let the technician know the furnace's age. Send a request and an HVAC technician will get in touch.

Thermostat batteries

Replace thermostat batteries at the same time each fall so they don't die in the middle of a cold night.

Fall is busy

Technicians' schedules fill up quickly once the first cold arrives. Booking in late summer or early September is easier.

Noises and smells

A tune-up is a good time to mention any squeals, rumbles or unusual smells you've noticed, so the technician can trace them.

Between visits

Change filters, keep the area around the furnace clear and dry, and check vent pipes outside after storms. Note any new noises or smells to mention at the next service.

Older furnaces

Older furnaces benefit most from annual checks, since worn parts and cracked heat exchangers become more likely with age.
