What changes about the house
- Heating: expect a longer or deeper heating season. Service the furnace or boiler before the first cold snap, and budget for higher heating bills.
- Cooling: hotter peaks make air conditioning or shading more important. Check attic insulation and window sealing so the house does not trap heat.
- Garden: a longer frost-free season opens more crop choices and succession sowings. Raised beds warm earlier in spring.
- Snow and ice: fewer freezing months reduce roof and driveway risk, but one surprise storm still happens. Keep basic winter tools for the odd freeze.
