Energy-Saving Tips for Your Air Conditioner

Hot weather is right around the corner. We’re slowly approaching the hottest months in Oakville, which means AC units will work overtime. Whether you recently installed a new AC in Oakville or are using an older unit, concerns about energy costs are growing in the GTA. Before you worry about the impact on your energy bill, we’re sharing simple and practical tips to reduce energy consumption while keeping you cool and comfortable.

How can you save energy with AC? These small changes can make a big difference in the long run.

10 Spring and Summer AC Energy-Saving Tips

#1. Correct Installation

Did you know poorly installed AC units work harder? Incorrect installation reduces the unit’s efficiency and durability, increasing monthly electricity bills. Always rely on a professional HVAC company to install a new AC unit.

How to tell if your AC was incorrectly installed:

  • It’s not cooling your home
  • It’s making strange noises, or you notice odd smells
  • Your energy bills have increased since the installation

#2. Don’t Forget Regular Maintenance

Well-maintained AC units function better and consume less energy. Although air conditioners are relatively low-maintenance, they do need general upkeep. You can do some things at home, like replacing the air filters every month. Other things are better left to the pros, like checking refrigerant levels and inspecting electrical terminals. Speak to an Oakville HVAC professional about how to best operate your system.

#3. Upgrade to Energy-Efficient Models

If your AC is over a decade old, think about replacing it to save on energy bills. Newer models use less electricity for the same cooling effect. If you’re considering installing a new AC in Oakville, look for units with a high SEER rating. SEER stands for Seasonal Energy Efficiency Ratio. These high-rated units are more efficient and can significantly reduce your electricity consumption.

#4. Turn Off Your AC at Night

If possible, keep your air conditioning system on during the day and turn it off while you sleep. Even on some of the GTA’s hottest days of the year, the air is cooler at night. Open your windows to allow the fresh air to flow through your bedroom and keep you cool.

Another option is using ceiling fans to complement your air conditioning by circulating cool air throughout the room. This allows you to set your thermostat a couple of degrees higher, reducing energy consumption without reducing comfort levels.

#5. Don’t Ignore “Warning” Signs

Is your AC making a strange noise? Does one area feel cooler than others? You probably need an air conditioner repair service. Common air conditioning problems, like wiring issues, leaking ducts, or clogged drains, cause your system to overwork, which means more energy consumption and higher electricity costs.

#6. Cover Your Windows

Around 30% of your home’s heating or cooling energy is lost through windows. The DOE recommends using energy-efficient window coverings, including solar screens and mesh-like window screens, to block the heat before it enters your house. Traditional window covers, like blinds, shades, or curtains, also work well.

Tip* Window screens are most effective on east and west-facing windows.

#7. Avoid Heat-Producing Activities

Heat-generating appliances like ovens, stoves, or dryers can increase the indoor temperature, forcing your AC to work harder and use more electricity. We’re not suggesting you stop cooking or doing your laundry, but try to use heat-producing appliances more in the evening when the air is generally cooler.

Another way to reduce the overall heat in your home is to invest in energy-efficient alternatives, like LED lights or energy-efficient appliances, which can help minimize the heat output and relieve the workload on your air conditioner.

#8. Use a Smart Thermostat

You can program smart thermostats to suit your schedule. When you’re not home, you can turn your AC off and set it to turn on right before you return. Don’t worry about being away from home for long periods – with these settings accessible from your smartphone, you can ensure everything is taken care of, no matter where you are.

#9. Seal and Insulate Ductwork

Functional HVAC systems require healthy and clean ductwork. Leaky or clogged ducts can lead to significant energy loss. Proper sealing is important to prevent cool air from escaping into your attic or crawl spaces before it reaches your living areas.

Dirty air ducts can also cause poor indoor air quality. It’s necessary to have your air ducts checked and cleaned regularly to ensure that your HVAC system is functioning correctly and that your indoor air is clean and healthy.

#10. Don’t Set the Temperature on Your Thermostat Too Low

It’s best to set your thermostat at a comfortable temperature and keep it consistent to avoid unnecessary energy usage. Temperatures in Oakville can get high, especially during June, July, and August. During summer, the temperature can reach up to 26° to 30°. Setting your thermostat for a temperature below 18° will put a lot of pressure on your AC to maintain the chilly temperature. Instead, setting the temperature between 20° and 25° will prevent your AC from working overtime and save you from high energy bills.
