The Real Cost of Energy Loss in Homes and BusinessesMost property owners don’t realize how much energy (and money) is lost every month due to outdated or inefficient infrastructure. Whether you're managing a commercial warehouse or living in a family home, poor insulation, aging HVAC systems, and inefficient lighting could be costing you thousands per year.
Common Sources of Energy Waste (and How Much They Cost You)
1. HVAC Systems (20–40% Energy Waste)Leaky ductwork, clogged filters, and aging HVAC systems can force your heating and cooling to work overtime. On average, up to 40% of your heating or cooling may be lost through inefficient HVAC systems. A modern heat pump or updated HVAC system can reduce this dramatically and may qualify for federal and provincial rebates.
2. Window & Door Leaks (15–30% Energy Loss)Poorly sealed windows and doors are one of the top culprits for energy waste. Drafts and thermal leakage can cause HVAC systems to run constantly, especially in Ontario winters. Air sealing and insulation upgrades can lead to major savings and increased comfort.
3. Lighting Systems (10–20% of Your Hydro Bill)Many homes and businesses still rely on outdated fluorescent or halogen lighting. Switching to LED lighting can reduce lighting costs by up to 80% and may qualify for lighting retrofit incentives.
4. Lack of Solar Offset (25–100% Savings Potential)Without solar panels, you're paying full price for electricity. Solar can offset anywhere from 25% to 100% of your power consumption depending on system size and battery storage. Plus, with net metering, you can earn credits for excess energy.
5. No Heat Pump? You're Missing Out
Heat pumps are one of the most efficient heating and cooling systems available. With new incentives, Ontario property owners can access rebates to cover 30–50% of heat pump system costs, depending on eligibility.
