Safety Warnings

Never attempt to repair gas lines, heat exchangers, or refrigerant systems yourself. These require TSSA-licensed professionals.
If you smell gas (rotten egg odour), leave your home immediately. Do not use light switches or phones inside. Call your gas utility from outside.
Change your carbon monoxide detector batteries every year. CO poisoning from faulty furnaces can be fatal.

Step-by-Step Guide

Replace your air filter regularly

Check your furnace filter monthly and replace it every 1-3 months. A dirty filter forces your system to work harder, increases energy bills, and reduces air quality. This is the single most impactful thing you can do.

Keep outdoor units clear

Maintain at least 2 feet of clearance around your outdoor AC unit or heat pump. Remove leaves, debris, and overgrown plants. Gently rinse the unit with a garden hose in spring.

Check and clean vents and registers

Vacuum dust from all supply and return vents throughout your home. Ensure furniture, rugs, and curtains are not blocking airflow. Blocked vents cause uneven heating and system strain.

Test your thermostat

Verify your thermostat is working correctly. Consider upgrading to a programmable or smart thermostat if you have not already. Proper thermostat settings can save 10-15% on energy bills.

Listen for unusual sounds

During operation, listen for banging, squealing, rattling, or clicking sounds. These indicate potential problems. Note when they occur (startup, running, shutdown) and report them to your HVAC technician.

Schedule professional maintenance twice yearly

Book a professional tune-up in spring (for AC) and fall (for heating). A TSSA-licensed technician will inspect gas connections, clean components, check refrigerant levels, and ensure safe operation.

Check your carbon monoxide detector

Test CO detectors monthly and replace batteries annually. If your CO alarm sounds, evacuate immediately and call 911. Carbon monoxide from faulty furnaces is colourless and odourless.
