Still heating with a floor furnace?

Many Hayward homes from the 1940s and '50s still have one under a hallway grate. We service them — and when it's time, we'll show you the replacement options side by side.

  1. Hot grate

    The grate gets hot enough to burn. Keep kids, pets and rugs clear.

  2. No cooling

    Floor furnaces heat only; there are no ducts for AC.

  3. Your options

    Service, a ductless heat pump, or a new ducted system.
