Quick tips

  • Set back the thermostat 2–3 °C at night and when away

    For gas-heated homes, a consistent 2–3 °C setback typically saves roughly 5–10% on heating. A programmable or smart thermostat makes it automatic.

  • Keep heat pump setbacks small

    Deep setbacks can trigger electric resistance backup heat during morning recovery, which is much less efficient. Keep setbacks to 1–2 °C or skip them.

  • Install a smart thermostat

    A smart thermostat automates setbacks and can be controlled remotely. HRS has offered a $100 rebate on qualifying models; confirm current terms.

  • Check the furnace filter monthly in winter

    A dirty filter restricts airflow, makes the blower work harder and can shorten equipment life. Replace it every one to three months depending on the filter type and household.

  • Book an annual heating tune-up

    A licensed technician can catch problems early and keep efficiency up. Gas appliances should be serviced by a TSSA-licensed G1 or G2 technician.

  • Keep vents and cold-air returns clear

    Furniture, rugs or drapes over registers block airflow and leave rooms uneven. Clear returns are just as important as supply vents.
