Keeping Cool in a Lethbridge Summer
Daytime highs in late July average about 26 °C, and some days top 35 °C. A few habits help your AC keep the house comfortable.
Request an HVAC technicianStart with the filter
A clean filter keeps air moving and stops the coil from freezing. Check it monthly in summer.
Clean the outdoor unit
Wind-blown dust and seeds clog the outdoor coil. With the power off, rinse it gently from the inside out.
Block the sun
Close blinds on west-facing windows in the afternoon. Less heat coming in means less work for the AC.
Steady settings
Keep the thermostat at a steady, comfortable setting rather than turning it far down. The AC removes heat at a set rate.
Spring tune-up
Book a tune-up before the first hot spell. See air conditioning.
When it struggles
If the AC runs nonstop, ices up or blows warm air, turn it off and book a repair.
Cool nights help
Dry prairie air cools quickly after sunset. On nights when it drops well below indoor temperature, opening windows and running the furnace fan can bring cool air in and give the AC a break. Close up again in the morning before the heat builds.
Help from the furnace fan
Running the furnace fan on low between cooling cycles can even out temperatures between floors. Upstairs rooms in two-storey homes often run warmer, and gentle mixing helps.
Think about the attic
A hot attic radiates heat into upstairs rooms all evening. Good attic insulation and ventilation reduce the load on the AC, and sealing ducts that run through the attic stops cool air being lost before it reaches the rooms.
Smoky days
On days when wildfire smoke drifts in, keep windows closed and let the AC recirculate indoor air through a clean filter.
