When summer temperatures rise in Alberta, your air conditioner becomes one of the most essential systems in your home. But without proper maintenance, even the most reliable AC unit can lose efficiency or fail when you need it most. Preparing your system before the heat hits ensures comfort, efficiency, and savings all season long.
Here are essential air conditioning maintenance tips to get your system summer-ready, based on expert recommendations and industry best practices.
1. Replace or Clean Your Air Filters
Clogged or dirty filters restrict airflow, reduce system efficiency, and can damage components over time. According to the U.S. Department of Energy, replacing a dirty filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%, leading to significant savings on your energy bills.
Tip: Check your filters monthly and replace or clean them every 1–3 months, depending on usage and whether you have pets or allergies.
2. Clear Debris from the Outdoor Unit
Over the winter, leaves, dirt, and debris may have built up around your outdoor condenser unit. This can block airflow and force your system to work harder, reducing its lifespan and increasing your energy bill.
Steps to take:
- Trim nearby vegetation so there’s at least 2 feet of clearance around the unit.
- Gently hose down the fins and coils to remove dust and debris.
- If the fins are bent, a fin comb can help straighten them.
3. Inspect the Thermostat
Now’s the perfect time to test your thermostat to ensure it’s reading the indoor temperature correctly and communicating with your AC. If you haven’t already, consider upgrading to a smart thermostat, which can enhance comfort and reduce energy costs by learning your cooling habits.
According to Natural Resources Canada, programmable and smart thermostats can reduce cooling costs by up to 10%.
4. Check Refrigerant Levels
Low refrigerant levels can cause your system to run inefficiently or even fail completely. Signs of low refrigerant include:
- Ice on the refrigerant lines
- Hissing or bubbling sounds
- Warm air blowing from vents
If you notice any of these signs, do not try to top off the refrigerant yourself—this requires a licensed HVAC professional. Refrigerant leaks also harm the environment and need to be adequately sealed.
5. Clean Vents & Ductwork
Blocked or dirty vents reduce airflow, making it harder for your AC to cool your home. Take a moment to:
- Remove dust from vent covers
- Ensure furniture or rugs aren’t blocking airflow
- Schedule a professional duct cleaning if it’s been a few years or you notice excess dust
Clean ducts improve both efficiency and indoor air quality, which is especially important during wildfire season or allergy season in Alberta.
6. Book a Professional AC Tune-Up
An annual inspection by a certified technician is the best way to catch minor issues before they become costly repairs. During a tune-up, Crystal Waters Home Comfort technicians:
- Inspect electrical components
- Calibrate the thermostat
- Check refrigerant levels and test for leaks
- Lubricate moving parts
- Inspect condensate drains to prevent water damage
Routine maintenance can extend the life of your AC system and maintain manufacturer warranties. The Canadian Centre for Occupational Health and Safety also notes that routine HVAC maintenance improves indoor air quality and reduces environmental risk.
7. Test Your System Before Peak Season
Don’t wait until a 30°C day to find out something’s wrong. Run your air conditioner for at least 15–20 minutes to check:
- It starts up without issue
- Cold air is coming from the vents
- No unusual noises or smells are present
If anything feels off, call Crystal Waters Home Comfort right away—you’ll avoid the summer service rush and stay ahead of potential breakdowns.
