Poor heating
The system runs but indoor temperature falls or backup heat operates unexpectedly.
Toronto heat pump service
Heat pumps work in more than one mode. Tell us whether the issue happens during heating, cooling or defrost and what the outdoor conditions are.

Useful before you call
A heat pump may show different symptoms as outdoor temperatures change. Poor heating, unusually long operation, heavy ice that does not clear, a system stuck in one mode, new noise or a backup-heat message can each point to a different service path.
Note the thermostat message, outdoor temperature, whether the fan is moving and whether the problem affects one indoor head or the whole home. Do not open electrical panels or attempt to remove ice with tools.
Common service paths
These descriptions help you explain the situation. They are not a substitute for an on-site diagnosis.
The system runs but indoor temperature falls or backup heat operates unexpectedly.
Heavy outdoor-unit ice remains and does not clear during normal operation.
The system will not switch between heating and cooling or shows a control error.
New sound, vibration, weak airflow or unusually long run times need diagnosis.
Questions before service
A light frost can occur in heating mode and the system should periodically defrost. Heavy ice that persists or blocks the coil warrants service.
Heat pumps often run longer than furnaces, especially in colder weather. A falling indoor temperature, error message or sudden change in performance is more useful to report.
Record the thermostat message, outdoor conditions, operating mode and whether the issue affects the full system or one zone.
