Seal Leaks And Insulate

To prevent heat loss and drafts, it’s crucial to seal any gaps or leaks in your home’s walls, windows, and doors. Proper insulation can significantly reduce the workload on your HVAC system. Use weatherstripping or glue to fill in any gaps you find around doors and windows. Consider adding insulation in your attic, basement, and walls to further improve energy efficiency.

Replace Or Clean Air Filters

If your air filter is dirty or jammed, it can stop air from moving through your HVAC system, making it less effective. Usually, every one to three months, check your air filters and repair them if they need to be. High-efficiency filters can help improve indoor air quality and reduce strain on your system, leading to energy savings.

Adjust Your Thermostat

One of the simplest ways to save on heating costs during winter is to adjust your thermostat settings. Lower the temperature when you’re away or sleeping, and raise it when you’re at home and awake. A programmable or smart thermostat, such as those available at, can automate temperature adjustments, making it even more convenient to save energy without sacrificing comfort.

Seal And Insulate Ductwork

Leaky or uninsulated ducts can lead to significant heat loss and reduced efficiency in your HVAC system. Check your ducts for leaks and use special tape or mastic glue to fix them. You might also want to insulate your ducts to keep heat from escaping as warm air moves from your heater or heat pump to different places in your house.

Upgrade To An Energy-Efficient System

If your HVAC system is outdated and inefficient, you may want to consider upgrading to a newer, energy-efficient model. Modern systems are designed to be more environmentally friendly and can result in substantial energy savings over time. Check out the energy-efficient options available on for potential upgrades.

Maintain Proper Ventilation

In the winter, when homes are shut up tight to keep the heat in, proper ventilation is very important for keeping the air quality inside healthy. When cooking or taking a shower, use air fans to get rid of extra wetness and stop mould growth. Ventilation can also help keep the air level in your home at a healthy level.

Clean And Maintain Your Heating System

For your heating system to work well and last a long time, it needs to be serviced regularly. Keep the area around your furnace or heat pump clean and clear of debris. Lubricate moving parts, check the ignition system, and ensure that the heat exchanger is free of cracks or damage. A well-maintained system runs more efficiently and reduces the risk of breakdowns.

Use Natural Sunlight

During sunny winter days, take advantage of natural sunlight to heat your home. Open your curtains or blinds during the day to let the sun’s warmth in, and close them at night to retain the heat. This simple practice can help reduce your reliance on your HVAC system.

Consider A Humidifier

The air in the winter is often dry, which can make your home feel cooler than it really is. Using a humidifier can add moisture to the air, making it feel warmer and more comfortable. This allows you to lower your thermostat slightly without sacrificing comfort, leading to energy savings.
