You will want to call for repair or think about replacing when you see:
- Inconsistent or weak airflow
- Varying room temperatures between rooms (hot/cold spots)
- Frequent on/off cycling of equipment
- Sharp increases in energy bills
- The system is aging (e.g. furnace 15-20 years, AC over 10-15 years)
Since both extreme cold and humid summer heat affect Innisfil comfort, aging or inefficient systems can labour — so prompt help can provide more comfort and save money in the long term.
