When something sounds off — a rattle in your furnace, lukewarm water, or an air conditioner that suddenly smells dusty — most homeowners do what everyone does: they ask the internet. “Is my hot water tank going bad?” “Why is my furnace making that noise?” “Should I shut off my AC for the winter?” These are real questions, and at Top Notch Mechanical Ltd. in Lethbridge, we answer them every single day.
“How do I know if my hot water tank is healthy?”
A healthy hot water tank should heat consistently, run quietly, and drain clear water when flushed. Signs of trouble include rusty water, popping noises, or visible leaks near the base. Most tanks last around 10 years — if yours is older, a professional inspection could prevent a costly flood. Learn more about hot water tank installation & service.
“Why does my furnace keep running or cycling too often?”
Short cycling usually points to restricted airflow, a dirty filter, or thermostat calibration issues. If your furnace starts and stops every few minutes, it’s working harder than it should. Schedule a quick tune-up before the heating season begins — it can cut energy use and extend your system’s lifespan. See our furnace installation and service options.
“What maintenance should I do for my HVAC system each year?”
The best thing you can do for your HVAC system is give it seasonal care. Replace filters every 3 months, clear debris from exterior units, and schedule a professional inspection twice a year — once before winter and once before summer. This helps keep airflow strong and prevents sudden failures. Explore duct & airflow installation and service.
“Should I cover my AC unit in the winter?”
A light, breathable AC cover can help protect coils from debris, but avoid sealing the system airtight — trapped moisture can cause rust. The real key is a proper end-of-season cleaning and shutting off power to the outdoor unit. If your system is over 10 years old, spring is the perfect time to plan a pre-summer tune-up.

“How can I make my home systems last longer?”
Regular maintenance is the single most effective way to extend the life of your equipment. Keep vents open, filters clean, and don’t ignore small noises or leaks — they’re your early warnings. Modern systems from brands like Rheem, Goodman, and Lennox are built for long-term performance when properly serviced.
