What's different about HVAC services in London

London, ON HVAC planning needs to account for freezing winters and warm summers. ECCC’s 1991–2020 normal records a January daily average of −5.4 °C, a July average of 21.0 °C, and 961.6 mm of typical annual precipitation. Winter no-heat and summer no-cooling calls have the highest demand, so non-urgent maintenance is better scheduled in spring or fall. Homeowners can replace filters and keep outdoor units clear, but diagnosis and electrical, gas, or refrigerant work require a certified HVAC technician.

London’s older housing stock can affect HVAC scope: 52,265 occupied dwellings dated to 1961–1980, while 39,135 dated to 1960 or earlier. This matters in established areas such as Old North, Wortley Village, and Old East Village, where equipment age, condition, and ductwork modifications may need review. For fuels-related HVAC work, verify the contractor’s TSSA registration and the technician’s applicable certificate. Confirm permit exemptions with the City of London Building Division before work begins.
