In Ontario, a heating and cooling system works one season hard and then hands the load to the other. Your furnace grinds through freezing months, your air conditioner carries humid summer weeks, and neither gets much of a break. That rhythm is exactly why the service question has a real answer for Strathroy homeowners: twice a year, every year, once before each busy season.
Cleaning, Testing, and the Safety Checks That Matter
Maintenance breaks into three kinds of work. Cleaning: coils, burners, and the outdoor unit, because dirt is what drives up run times. Testing: refrigerant charge, gas pressure, ignition, electrical connections, thermostat accuracy, and airflow at the vents. Safety: a heat exchanger inspection and a combustion check that catches carbon monoxide risks before they become emergencies.
The filter gets replaced at every visit as a matter of course. You leave with a system that has been cleaned, measured, and adjusted rather than simply glanced at.
What Happens When Maintenance Gets Skipped
Skip service for a couple of years and the signs show up on their own schedule. Energy bills creep upward because dusty burners and clogged coils force longer run times. Some rooms start feeling warmer or cooler than others. Airflow at the vents weakens, and the air itself can feel stale and dusty.
None of it looks like an emergency, which is the problem. Small issues that a routine visit would have caught quietly turn into expensive repairs at the worst possible time, usually the first genuinely cold week or the first long heat wave of the season.
The Ideal Service Schedule in Ontario
In a climate with a real winter and a real summer, servicing HVAC equipment twice a year makes the most sense: once in spring before the air conditioner starts its season, and once in fall before the furnace takes over. That is the minimum, not a bonus.
The fall appointment matters because heating season is long and unforgiving, and you want the furnace inspected before it matters. The spring appointment matters because the air conditioner sits idle for months and needs cleaning and testing before the first hot stretch. Two visits, evenly spaced, and neither season catches you unprepared.
Fewer Breakdowns, Lower Bills, Longer Life
The benefits of maintenance compound in three directions at once. Efficiency: clean coils, clear filters, and tuned burners mean shorter run times and visibly lower energy bills. Reliability: problems get caught at routine prices instead of emergency ones, which is why maintained homes see far fewer mid-season failures. Lifespan: equipment that is cleaned and adjusted every six months simply lasts longer, often years longer than the same units would have managed neglected.
Add it up and maintenance is one of the rare expenses that pays a return every month, not just at breakdown time.
