According to Environment and Climate Change Canada, 2026 is expected to be among the hottest years on record. For homeowners in London, Ontario, that is a good reminder to make sure your cooling system is ready before summer temperatures rise.
If your home uses a central air conditioner or a heat pump, spring is the best time to check that everything is working properly. Heat pumps are not just for heating — they also provide cooling in summer, which makes spring maintenance important for both types of systems.
Before the hot weather begins, it is a smart idea to:
- check or replace your air filter
- test your cooling system early
- make sure airflow feels normal in the main rooms
- check that the thermostat is working properly
- clear debris around the outdoor unit
- watch for weak cooling, strange noises, or water leaks
Small problems often become more noticeable once the weather gets hotter and the system has to work harder. Booking an AC tune-up, AC maintenance, or heat pump maintenance in spring can help catch issues early and improve peace of mind before peak summer arrives.
If your system is already showing signs like poor airflow, warm air, unusual sounds, or trouble keeping your home comfortable, it may be time to schedule an AC repair or heat pump repair instead of waiting for the first heat wave.
With a hotter summer possible in 2026, early preparation is one of the best things London homeowners can do. A simple seasonal check now can help you stay comfortable and avoid unexpected cooling problems later.
