Lower Your Energy Bills:
5 HVAC Efficiency Tips for London, Ontario
Your HVAC system is the biggest energy user in your home, accounting for over 50% of your utility bills. For London homeowners dealing with our cold winters and humid summers, those costs add up fast. But with the right strategies, you can slash your energy bills significantly without sacrificing comfort. Here are five proven tips from Hawana HVAC's lead technician, Abdullah Ghzail.
1. Schedule Annual Professional Maintenance
This is the single most effective way to ensure peak efficiency. A neglected furnace or AC can lose up to 5% of its efficiency each year. During a professional tune-up, our TSSA-certified technicians clean coils, check refrigerant levels, lubricate motors, and calibrate your system to run as efficiently as possible. For just $149/year (Basic Plan), you'll save over $100 on heating bills in a single winter — the plan pays for itself.
2. Upgrade to a Smart Thermostat
Stop heating or cooling an empty house. A programmable or smart thermostat allows you to create custom temperature schedules that automatically lower the temperature when you're asleep or away. According to Natural Resources Canada, a smart thermostat can reduce your heating and cooling costs by 10-15% annually. At Hawana, we install and set up smart thermostats for London homeowners, ensuring optimal schedules for our climate near Victoria Park and along the Thames River.
3. Change Your Air Filter Regularly
A clogged air filter is like forcing your HVAC system to breathe through a straw. It restricts airflow, making the motor work harder and use more energy. This simple task is crucial for efficiency.
✓ Filter Check Routine
- Check monthly: Hold the filter up to a light. If you can't see light through it, it's time for a change.
- Change every 1-3 months: Depends on your home (pets, smokers, etc.) and filter type.
- Energy impact: A clean filter can lower energy consumption by 5-15% and prevent motor burnout.
4. Seal Air Leaks in Your Home and Ductwork
Why pay to heat air that just escapes outside? Use weatherstripping and caulk to seal leaks around windows and doors. More importantly, have your ductwork inspected. Leaks in your duct system can account for 20-30% of lost conditioned air. Professional ductwork sealing ensures the air you pay to heat or cool actually reaches your rooms — eliminating hot and cold spots that force your system to run longer.
5. Invest in High-Efficiency Upgrades and Rebates
If your furnace or AC is over 15 years old, it's likely far less efficient than modern units. Upgrading to a new 96% AFUE furnace or a modern heat pump can cut your heating costs dramatically. Plus, you can take advantage of valuable programs:
- Enbridge rebate: Up to $650 for qualifying furnace or boiler upgrades
- Greener Homes grant: Up to $5,000 for eligible energy retrofits
- OHRSP heat pump rebate: Up to $7,500 for cold-climate heat pumps
- Check London Hydro's programs for additional incentives on energy audits

Real Savings from London Homeowners
Reed K. · Victoria Park area
"Hawana saved us over $200 on heating bills just from the maintenance plan. Abdullah tuned our 12-year-old furnace, cleaned the blower, and found a small gas leak we never knew about. Fixed it same day for a fair price. Unlike companies that charge after-hours premiums, they came on a Saturday with zero surcharge."
Moss B. · Riverside Drive
"We were looking at $6,000 for a furnace from rental companies. Hawana installed a 96% AFUE Goodman for $3,400 outright — no rental contract, no hidden fees. Abdullah walked us through the Enbridge rebate, and we got $650 back. The pricing transparency was refreshing compared to others who hide costs."
Cliff T. · Near Western University
"We combined a heat pump with a new furnace and saved $7,500 through the OHRSP grant. Total was $6,500 for both including installation. The heat pump handles cooling and mild heating, and the furnace kicks in during February cold snaps. Hawana handled all the grant paperwork and our energy bills dropped 30%."
Energy Efficiency FAQs
By restoring your furnace to factory specifications, a professional tune-up can improve efficiency by 5% or more. For the average London household, this can translate to over $100 in savings on heating bills over a single winter, easily covering the cost of the service.
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. The minimum standard is 90%, but high-efficiency models boast ratings of 95% to over 98%. Choosing a furnace with a 96% AFUE or higher will provide significant long-term savings in our cold climate.
This is a common myth. The idea that it takes more energy to reheat a house than to maintain its temperature is incorrect. According to Natural Resources Canada, you can save significant energy by lowering your thermostat overnight or when you're away. A programmable or smart thermostat makes this effortless.
Check your filter monthly and change every 1-3 months. If you have pets, smokers, or allergy sufferers, change monthly. A clean filter can lower energy consumption by 5-15% and prevent motor burnout from restricted airflow.
London homeowners can access up to $650 Enbridge rebate for furnaces, up to $5,000 Greener Homes grant, and up to $7,500 OHRSP rebate for heat pumps. Check London Hydro's programs and Ontario's energy conservation grants for additional incentives.
Leaky ducts can waste 20-30% of conditioned air. Professional duct sealing ensures the air you pay to heat or cool actually reaches your rooms. This often reduces energy bills by 15-25% and improves whole-home comfort by eliminating hot and cold spots.
Replace your furnace if it's over 15 years old, requires repairs costing 50% of a new unit's price, or has a cracked heat exchanger. A new high-efficiency furnace can cut heating bills by 20-40% compared to an old 80% AFUE model.
Yes. Basic Maintenance is $149/year and includes annual tune-up, filter change, and priority service. Premium Maintenance is $249/year and adds two tune-ups per year (furnace + AC), 15% repair discount, and waived diagnostic fees.
Smart thermostats learn your schedule and temperature preferences, then automatically adjust when you're asleep or away. They also provide energy usage reports and can be controlled remotely via smartphone, saving 10-15% on bills without any manual effort.
Skipping annual maintenance is the #1 mistake. A neglected furnace or AC loses 5% efficiency each year. By year five, you're wasting 25% on energy bills. Professional tune-ups pay for themselves through lower utility costs and prevent expensive emergency repairs.
