Calgary’s winter can be harsh, with freezing temperatures and snow-covered landscapes.
During this season, your furnace becomes one of the most critical components of your home. Ensuring it operates efficiently is about more than just comfort, safety, and energy savings.
As trusted Calgary plumbers and heating experts, we provide tips and precautions to help you keep your furnace running smoothly throughout the winter. Here’s what you need to know.
Schedule a Pre-Winter Inspection
Before the cold sets in, it’s essential to have your furnace professionally inspected. Regular maintenance ensures all components are in top condition and helps identify potential issues early.
With our expertise in furnace repair in Calgary, we can check for worn-out parts, clean essential components, and verify the system’s overall efficiency. An annual inspection can save you from unexpected breakdowns during the coldest months.
Replace or Clean Filters Regularly
Clogged or dirty filters can reduce your it’s efficiency, increase energy consumption and even lead to overheating. We recommend checking your filters monthly and replacing or cleaning them as needed during the winter. A clean filter allows proper airflow, helping your furnace work less and extend its lifespan.
Seal Air Leaks in Your Home
Even the most efficient furnace can only work if your home has air leaks. Gaps around windows, doors or ducts allow warm air to escape, forcing your heating system to work harder.
Seal any leaks with weatherstripping or caulking, and consider adding insulation to your attic or basement to improve your home’s heat retention.
Check Your Thermostat Settings
Ensure your thermostat is set to an energy-efficient temperature.
Keeping your home warm without overheating saves energy and reduces wear and tear.
Consider upgrading to a programmable or smart thermostat for even better control. These devices allow you to customize heating schedules and monitor usage remotely, helping you maintain an efficient system.
Keep Vents and Registers Clear
Blocked vents and registers can disrupt airflow and strain your furnace unnecessarily. Ensure furniture, curtains, or other objects aren’t obstructing these outlets—also, regularly clean dust and debris from vents to maintain optimal airflow.
Monitor Carbon Monoxide Levels
Furnaces that burn gas produce carbon monoxide (CO), a colourless, odourless gas that can be dangerous if not properly vented. We recommend installing CO detectors throughout your home and checking them regularly to ensure they function correctly.
As a minimum precaution, you should have a working CO detector in the mechanical room. During maintenance, we inspect your furnace for cracks or blockages in the heat exchanger and flue system, ensuring your family’s safety.
Keep the Area Around Your Furnace Clear
It needs proper ventilation to function efficiently. Keep the area around it free of clutter, particularly flammable materials like cardboard, paint, or cleaning supplies. A clean and unobstructed area reduces fire risk and improves airflow.
Know When to Call for Repairs
If you notice unusual noises, uneven heating or an unexplained spike in your energy bills, these could be signs your furnace needs professional attention. Addressing these issues promptly can prevent further damage and costly repairs. As specialists in Calgary, we’re ready to help diagnose and fix any problems your system may face.
Consider a Furnace Replacement if Needed
If your furnace is over 15 years old and requires frequent repairs, it might be time to consider a replacement. Modern units are significantly more energy-efficient and can save you money on utility bills in the long run. We can help you choose a new system that suits your home’s size and heating needs, ensuring a seamless installation process.
