Keep Your Cool This Summer: Essential HVAC Tips from LG Mechanical
HVAC Tips for Summer 2025
Summer in Ontario means backyard barbecues, long sunny days, and—let’s be honest—some seriously hot weather. If your air conditioning system isn’t ready to handle the heat, you could be looking at uncomfortable, sweaty days ahead. The good news? A little prep work now can save you from emergency breakdowns and sky-high energy bills later. Let’s dive into some easy yet essential HVAC maintenance tips to keep your home cool and comfortable all season long.
1. Swap Out Your Air Filter Regularly
Think of your AC’s air filter like a lint trap in your dryer—if it’s clogged, airflow suffers. A dirty filter makes your system work overtime, driving up energy costs and reducing cooling efficiency. To keep things running smoothly, replace or clean your air filter every 1–3 months, especially if you have pets, allergies, or a home prone to dust. Better airflow means better cooling—and lower bills!

3. Clear Debris Around Your Outdoor Unit
Your outdoor AC unit needs breathing room to function properly. Leaves, dirt, and other debris can clog up the system, making it less efficient. Give your unit at least two feet of clearance by trimming nearby bushes and removing any obstructions. For an extra boost in performance, gently hose down the coils to remove built-up dirt. Just remember to turn off the power first—safety first!

5. Upgrade to a Smart Thermostat
If your thermostat is still the old-school dial type, it’s time for an upgrade. Smart thermostats learn your schedule and adjust temperatures automatically to save energy while keeping your home comfortable. Plus, they allow you to control your HVAC system from your phone—so if you forget to adjust the temp before heading out, you can fix it with a tap. Bonus: Ontario residents may qualify for rebates when upgrading to an energy-efficient thermostat!

6. Insulate Your Home to Lock in Cool Air
Good insulation isn’t just for winter. In summer, it helps keep the cool air inside where it belongs. Check your attic, crawl space, and basement insulation—if they’re lacking, consider adding more. Proper insulation keeps your home comfortable while reducing strain on your AC system, helping you save on energy costs.

7. Make Sure Your Vents Are Open and Unblocked
It might sound obvious, but blocked vents can seriously reduce your AC’s effectiveness. If furniture, rugs, or curtains are covering air vents, they’re preventing proper airflow. Walk around your home and ensure all vents are clear so that cool air can circulate freely.

8. Test Your AC Before the First Heatwave
The last thing you want is to turn on your AC during the first 30°C day only to realize it’s not working. Test your system early in the season by switching it on and ensuring it cools properly. If you hear strange noises, notice weak airflow, or experience inconsistent cooling, call LG Mechanical before peak season arrives. Getting ahead of potential issues can save you from sweltering days and long repair wait times.

9. Consider an Energy Audit
Want to maximize your home’s energy efficiency? A professional energy audit can pinpoint where you’re losing cooled air and recommend upgrades that save you money. Simple changes—like sealing windows, adding weather stripping, or upgrading insulation—can make a huge difference in your home’s cooling efficiency.

10. Stay Hydrated & Keep Your Cool
While your HVAC system keeps your home cool, don’t forget about yourself! Drink plenty of water, use ceiling fans to circulate air, and close blinds during peak sunlight hours to prevent excess heat buildup. A little planning goes a long way in keeping both you and your home comfortable all summer long.
