Useful before you call
Useful details for a Mississauga heat pump repair call.
Longer run times can be normal for a heat pump, especially in cold weather, but a falling indoor temperature, persistent heavy ice, a fault code, weak airflow or a sudden change in sound deserves attention. Backup heat behaviour is another useful clue.
Mississauga includes older detached homes, townhouses, high-rise suites and newer subdivisions. Equipment age, venting, electrical capacity and the way air or water is distributed can vary considerably between properties.
Do not open electrical compartments, add refrigerant or strike ice from the outdoor coil. Keep the unit clear of loose debris and record the thermostat message before switching the system off if operation appears unsafe.
For Mississauga properties, report whether the heat pump works with a furnace or air handler and whether the concern appears during a temperature change. That helps separate mode and backup-heat questions.
Share the operating mode, outdoor temperature, set point, thermostat or equipment code, ice pattern, affected zones and whether backup heat appears to operate. Call 647-478-2056 for the ASAP HVAC Mississauga Valleys location and include the property postal code.

Questions before service
Clear, useful answers.
Is frost on a heat pump normal?
Light frost may occur in heating mode and should periodically clear. Heavy ice that persists or blocks the coil needs attention.
Why does a heat pump run longer than a furnace?
Heat pumps often deliver heat more gradually. A sudden change, falling indoor temperature or fault message is more important than run time alone.
What is backup heat?
Some systems use a secondary heat source under certain conditions. Report when the thermostat indicates backup or auxiliary heat and whether comfort is maintained.
