Summer doesn’t just bring sunshine. It brings higher energy bills, overworked HVAC systems, and households scrambling to stay cool and while many homeowners think turning the thermostat lower is the only fix, the truth is that a few smart changes can make a big impact.
We asked local HVAC contractors what works to keep homes comfortable and costs low during Edmonton’s hottest months. This guide is a collection of their most effective, realistic advice, no fluff, no guesswork.
Practical Tips For Saving Energy
Schedule A Pre-Summer HVAC Tune-Up
This is one of the simplest ways to reduce your cooling costs. HVAC contractors often catch small issues like clogged coils or low refrigerant before they turn into system-wide problems.
What a tune-up usually includes:
- Checking refrigerant levels
- Cleaning coils and blower parts
- Inspecting electrical connections
- Testing airflow and thermostat calibration
A well-maintained system runs smoother, lasts longer, and uses less power to do the same job.
Use Your Thermostat The Smart Way
You don’t need to keep your home at 20°C all day to stay cool. Set your thermostat around 24–25°C when you’re home and bump it up a few degrees when you’re away or sleeping.
Smart thermostats take this a step further; they learn your habits, adjust temperatures automatically, and even send alerts if something’s off. Many utility providers also offer rebates on smart thermostats, making it a worthwhile upgrade.
Improve Insulation & Sealing
It’s easy to forget that keeping cool air in is just as important as creating it. Check your attic, walls, and basement for insulation gaps. Weatherstrip your doors and seal any cracks around windows.
If your home is poorly sealed, your HVAC system ends up cooling the outdoors. That’s money lost.
Use Fans To Support (Not Replace) Cooling
Ceiling fans won’t cool the room, but they’ll help cool you. Set fans to spin counterclockwise in summer to push air downward. You’ll feel cooler, which means you can keep your thermostat higher without sacrificing comfort.
Even portable fans near high-use areas like kitchens or bedrooms can reduce the need to run your AC full blast.
Watch Out for Heat-Generating Appliances
Ovens, stoves, and even dryers add heat to your home. During peak afternoon hours, that heat competes with your AC, making it work harder.
Here’s what helps:
- Cook earlier or later in the day
- Use the microwave or slow cooker
- Air-dry clothes when possible
- Run your dishwasher at night
Small adjustments here lead to real savings over time.
Shade Your Windows
Direct sunlight through glass can increase indoor temperatures dramatically. In rooms with big windows, even basic window treatments can help a lot.
Try these:
- Close blinds or curtains in the afternoon
- Use thermal/blackout curtains for sun-facing rooms
- Apply UV-reflective window film
The goal is to block heat before it gets inside, reducing how much your HVAC system needs to fight.
Upgrade If Your System Is Near the End
If your HVAC unit is over 12–15 years old and struggling to keep up, it might be time to talk about replacement. Newer systems are built to be more efficient, quieter, and compatible with smart tech.
Ask licensed HVAC contractors to assess your current setup. They’ll let you know if a repair makes sense or if an upgrade will save you more in the long run. You may also qualify for government rebates or energy efficiency grants, so don’t forget to ask.
Monitor Your Usage
Your monthly bill tells a story and if you notice sudden spikes, it could be a sign your system needs attention. Some energy providers offer real-time usage dashboards, or you can install a home energy monitor. Tracking your usage helps you spot patterns, adjust settings, and stay in control.
Talk To Local HVAC Contractors For Personalized Help
Every home is different. What works for a 1,200 sq. ft. bungalow may not work for a two-storey duplex with pets and kids.
That’s why reaching out to experienced HVAC contractors in Edmonton is key. They’ll assess your space, your needs, and your current equipment, then suggest a plan that works. It’s advice based on your home, not a general checklist.
Quick Comparison: Old Habits Vs. Energy-Saving Fixes
| Common Summer Mistake | Energy-Saving Fix |
| Setting the thermostat very low all day | Install a smart thermostat & adjust temps by time of day |
| Running the AC with dirty filters | Clean/replace filters monthly |
| Keeping blinds open during peak sun | Use blackout curtains or UV-blocking films |
| Ignoring HVAC maintenance | Schedule a seasonal tune-up with HVAC contractors |
| Using the oven/stove in the afternoon | Cook earlier, or use an outdoor grill/microwave |
