Why Air Conditioners Struggle During Okanagan Summers
High daytime temperatures and warm nights keep AC systems running longer than usual. Dust, pollen, and hard‑water minerals can clog filters and coils, while power surges from summer storms stress electrical components. Knowing the most common issues helps you act fast before a small glitch becomes a major breakdown.
1. Weak or Warm Airflow
Clogged air filters, frozen evaporator coils, or low refrigerant are the usual suspects. Replace or clean the filter first, then shut the system off for an hour to thaw the coil. If airflow is still weak, schedule a professional refrigerant check.
2. Short Cycling (Frequent On‑Off)
A thermostat in direct sunlight, dirty outdoor coils, or an oversized system can cause rapid cycling. Shade or relocate the thermostat, gently rinse the condenser coils, and book an HVAC assessment if cycling persists.
3. Unusual Noises
Banging or hissing sounds often point to loose fan blades, a refrigerant leak, or worn motor bearings. Switch the unit off and call a technician to prevent compressor damage.
4. Water Leaks at the Indoor Unit
A clogged condensate drain, faulty pump, or frozen coil can leave water on the floor. Clear the drain line with a wet‑dry vacuum; if leaks continue, arrange professional cleaning and pump inspection.
5. High Energy Bills With Little Cooling
Dirty filters, low refrigerant, and aging equipment force the system to run longer than necessary. Replace filters monthly, keep the thermostat at 22–24 °C, and consider upgrading to a high‑efficiency heat‑pump system if your unit is over 15 years old. FortisBC rebates may offset the cost.
