Newmarket Homeowner Heating & Cooling Checklist

Seasonal checks can help you notice changes before they become a loss of comfort. These are general homeowner observations, not instructions to repair gas, electrical, or refrigerant equipment.

Before Ontario's colder weather

  • Review your furnace's operating instructions and recommended filter care.
  • Keep accessible supply and return vents unobstructed.
  • Test and maintain carbon monoxide alarms according to their instructions.
  • Note unusual sounds, repeated shutdowns, or rooms that remain cold, and ask a qualified technician about them.

Professional maintenance requirements vary by equipment. Follow the manufacturer and confirm the service available before booking.

Before hot summer days

  • Check the thermostat's cooling setting and observe whether the system starts normally.
  • Keep the area around an outdoor unit clear without opening the equipment.
  • Follow the manual for accessible filter care.
  • Record warm air, weak airflow, visible ice, or water around the equipment and contact the team rather than attempting a repair.

Carbon monoxide alarms and gas smells

If a carbon monoxide alarm sounds, leave immediately, get to fresh air, and call 911. Do not return until emergency responders say it is safe. If you smell gas, leave and call emergency services or your gas utility from a safe location. Do not operate switches or try to locate a leak.

Health Canada's carbon monoxide safety guidance

Prepare a useful service request

Describe the equipment, when the problem started, which rooms are affected, and any safely visible error code. Do not remove covers to find information. NorthPeak is open 24 hours; specific services and appointment availability are confirmed directly.

Should I try to repair the equipment myself?

Limit checks to manufacturer-directed homeowner tasks. Gas, electrical, combustion, and refrigerant work should be left to appropriately qualified professionals.
