Summers in the Okanagan are no joke — and your air conditioner works hard to keep up. Whether you live in Kelowna or along the lakefront in Peachland, proper maintenance helps your AC run efficiently, avoid mid-season breakdowns, and lower your utility bills.
Here are the top air conditioning maintenance tips to keep your home cool and comfortable all summer long.
1. Change or Clean Your Air Filter
Dirty filters reduce airflow and strain your system, which can lead to higher energy use and prevent proper cooling.
What to Watch For:
- Dust buildup on vents
- Reduced airflow from registers
- Unusual system noise
What to Do:
- Replace your filter every 1–3 months
- Use MERV 8 to 11 filters for balance between airflow and air quality
2. Clear Debris from the Outdoor Unit
Leaves, grass, and dust can build up around your condenser, restricting airflow and decreasing efficiency.
What to Watch For:
- Debris stuck in the fan blades or coils
- Overgrown landscaping close to the unit
What to Do:
- Trim plants and bushes around your AC
- Hose off the exterior fins gently once per season
- Leave 2–3 feet of clearance on all sides
3. Clean Air Vents and Keep Them Unobstructed
Proper airflow inside the home is just as important as outside.
What to Watch For:
- Rooms that feel warmer than others
- Furniture blocking vents
What to Do:
- Dust or vacuum all registers
- Rearrange furniture if necessary
- Consider duct cleaning if airflow issues persist
4. Upgrade to a Smart Thermostat (Rebate Available)
Smart thermostats help you manage your cooling system more efficiently.
What to Watch For:
- Inconsistent indoor temperatures
- High utility bills in summer
What to Do:
- Install a FortisBC-approved smart thermostat
- Apply for a rebate of up to $150

5. Book a Professional Cooling Tune-Up
Annual AC service ensures your system is ready for peak summer heat.
What to Watch For:
- Your system hasn’t been serviced in over a year
- Unusual sounds, smells, or weak cooling
What to Do:
- Book a tune-up before temperatures spike
- A technician will inspect electrical connections, check refrigerant, clean coils, and more
Schedule a tune-up
6. Consider a High-Efficiency System If Yours Is Over 15 Years Old
Older AC units can cost more to run and are prone to breakdowns.
