As the temperatures continue to rise in Windsor, so does the reliance on our air conditioning systems. However, opening your monthly hydro bill to find a massive spike in energy costs can be a major source of stress.
We want to help you understand why your AC might be working overtime and how you can bring those costs back down to earth.
1. Dirty Air Filters and Coils
The number one enemy of efficiency is restricted airflow. When your air filters are clogged with dust, pet hair, and debris, your AC has to work twice as hard to pull air through the system. Similarly, if the outdoor condenser coils are covered in dirt or grass clippings, the unit cannot release heat effectively.
- The Fix: Change your filters every 1 to 3 months and ensure the outdoor unit has at least two feet of clear space around it.
2. Leaky Ductwork
Did you know that the average home loses 20% to 30% of its conditioned air through leaks in the ductwork? If your ducts have holes or poor connections, you are essentially paying to cool your attic or the spaces inside your walls instead of your living room.
3. An Aging or Overworked System
Air conditioners generally have a lifespan of 15 to 20 years. As a unit ages, its mechanical components wear down, and it becomes less efficient at cooling. If your system is constantly running but the house never feels quite cool enough, it may be reaching the end of its life.
4. Incorrect Thermostat Settings
Setting your thermostat to a “polar” temperature won’t cool your home any faster; it simply keeps the compressor running longer. Large fluctuations in temperature settings can also cause short cycling or extended run times that drain power.
- The Fix: Invest in a smart thermostat. It can learn your schedule and adjust temperatures automatically when you are away or asleep, saving significant energy.
5. Lack of Annual Maintenance
An AC unit is like a car: it needs regular maintenance to perform at its peak. Without an annual tune-up, small issues like low refrigerant levels or worn electrical components go unnoticed, forcing the motor to draw more amps to compensate.
How to Lower Your Electricity Bill This Summer
If you’re looking to slash those energy costs, consider these three strategies:
- Upgrade Your System: Standard air conditioners operate like a light switch; they are either running at 100% capacity or they are completely off. This “all or nothing” approach creates huge spikes in electricity usage. Modern systems, such as those featuring variable-speed inverter technology, adjust their speed incrementally to match the exact cooling load
- Seal Your Home: Ensure your windows and doors are properly weather-stripped and your attic is well-insulated. This keeps the cold air in and the heat out.
- Use Ceiling Fans: Fans create a wind-chill effect, allowing you to raise the thermostat by about 4 degrees without losing comfort.
- Manage Solar Heat Gain: Your windows can act like a greenhouse. During the hottest parts of the day, keep your blinds or curtains closed, especially on south and west-facing windows. This simple habit prevents radiant heat from entering your home, reducing the load on your air conditioner by up to 30%.
- Optimize Airflow with Clear Vents: Ensure that furniture, rugs, or curtains are not blocking your supply or return vents. When airflow is obstructed, the system stays on longer to reach the target temperature, leading to higher bills and unnecessary wear on the blower motor.
