HVAC Tips & Tricks
Expert advice from Jaffna Comfort professionals to help you maintain your systems, reduce energy bills, and improve indoor air quality.
Winter Prep for Your Furnace
Before the first freeze hits Toronto, ensure your heating system is ready. Start by replacing the air filter—a dirty filter restricts airflow and forces your furnace to work harder. Check all vents to ensure they aren't blocked by furniture or rugs. Finally, test your thermostat to ensure it accurately triggers the heat cycle. If you smell gas or hear unusual banging noises, call a professional immediately.

Maximizing AC Efficiency in Summer
Keep your cooling bills low during heatwaves. Keep your blinds closed during the hottest parts of the day to block solar heat gain. Clear debris, leaves, and overgrown bushes from around your outdoor condenser unit to ensure proper airflow. Set your ceiling fans to rotate counterclockwise to push cool air down. Most importantly, don't set your thermostat artificially low (e.g., 65°F) hoping it will cool faster—it won't.

Indoor Air Quality Basics
Modern homes are tightly sealed for energy efficiency, which means indoor air can be 2-5 times more polluted than outdoor air. Invest in a high-MERV filter (MERV 11-13) if your system can handle it. Consider a whole-home humidifier in the winter to prevent dry skin and wood cracking, and ensure proper exhaust ventilation in bathrooms and kitchens to prevent mold growth.

Water Heater Flushing
Hard water can cause sediment to build up at the bottom of your tank water heater. This sediment acts as an insulator between the burner and the water, wasting energy and potentially causing the tank to overheat and fail prematurely. You should flush your tank annually. If you're not comfortable doing this yourself, schedule it during your annual HVAC maintenance visit.
