Why Is My Heating Bill So High? Ontario Winter Energy Savings Guide for London ON

Set lower temperatures to 18°C when away or sleeping, raise to 20-22°C when home—save up to 10% annually on heating bills. Smart thermostats like Nest or Ecobee learn your habits and optimize for Ontario winters, saving up to $150/year. Every degree above 20°C adds 5% to your bill, so proper programming is one of the easiest ways to reduce heating costs. We can help you set up optimal schedules during installation.

For ducts: use mastic sealant or foil tape on joints—prevents up to 30% heat loss in forced-air systems. For windows: apply caulk or weatherstripping around frames; add insulating film for drafty older homes. Install door sweeps and insulate attics. A professional energy audit can pinpoint leaks and qualify for Ontario rebates. These simple fixes often pay for themselves within one winter.

If your furnace is over 15 years old with less than 80% AFUE, upgrading to a 96%+ AFUE high-efficiency model saves $300-500/year in Ontario. Payback period is typically 5-8 years after rebates. Variable-speed models handle Southwestern Ontario's freeze-thaw cycles better. Call us for a free assessment to calculate your potential savings and rebate eligibility.

Home Renovation Savings Program (HRSP) offers up to 30% rebates on energy upgrades. Heat pump rebates up to $7,500. Enbridge Home Efficiency Rebate Plus provides up to $10,000 for comprehensive retrofits. Save on Energy programs offer incentives for smart thermostats and furnace tune-ups. Hawana handles all rebate paperwork at no charge. Many homeowners save thousands on upgrades.

Common causes: leaky ductwork (30% heat loss), poor insulation in attic or walls, drafty windows and doors, thermostat set too high, or incorrect furnace sizing. Even a new furnace can't compensate for major heat loss. Schedule an energy audit to identify the specific issues in your London home. We offer free assessments to diagnose efficiency problems and recommend targeted solutions.

Annual savings typically range from $300-600 on gas bills for an average London home. An 80% furnace wastes 20% of the gas you pay for. A 97% furnace wastes only 3%. Over the 15-20 year lifespan, total savings can reach $5,000-10,000. Combined with rebates (up to $1,500), the upgrade often pays for itself within 5-7 years. That's a return on investment most homeowners can't ignore.

Set to 20°C when you're home and awake, 18°C when sleeping or away. Each degree you lower the thermostat saves about 5% on heating costs. For example, lowering from 22°C to 20°C for 8 hours a day can save 10-15% annually. Smart thermostats automate these adjustments and can save up to $150/year in London homes. We can help you set up optimal schedules during installation.

Duct cleaning alone has minimal impact on energy bills. However, sealing leaky ducts can reduce heating costs by up to 30%. Focus on sealing joints with mastic sealant or foil tape. If your ducts are severely clogged with debris, cleaning may improve airflow slightly, but sealing is far more effective for energy savings. We offer duct sealing as part of our efficiency services and can assess your ducts during a visit.

Signs include: uneven temperatures between rooms, cold floors, ice dams on roof in winter, high heating bills despite normal usage, and drafty feeling near walls and windows. An energy audit with thermal imaging can identify insulation gaps. Many London homeowners qualify for rebates that cover part of the assessment cost. We can recommend trusted energy auditors and help you interpret their findings.

The most cost-effective steps in order: 1) Program your thermostat properly (free). 2) Seal ductwork and weatherstrip windows ($50-200). 3) Change furnace filters monthly ($20-50/year). 4) Schedule annual furnace maintenance ($149/year). 5) Upgrade to a smart thermostat ($250-650 after rebate). 6) Replace old furnace with 97% AFUE model ($3,400+ after rebates). Start with the free or low-cost fixes first—they often deliver the best return on investment.
