The question every homeowner asks is how often an HVAC system needs service, and the honest answer is short: twice a year. Cooling in spring, heating in fall, filters in between. No jargon, no upsell, just the reasoning from a local crew on why that rhythm works for Stratford homes and what it protects.
What the Technician Actually Does
Plan on about an hour per visit, and plan on questions being answered in plain language. The cooling visit walks through refrigerant, coils, electrical parts, thermostat, and airflow. The heating visit walks through the heat exchanger, burners, gas connections, ignition, and venting, with a carbon monoxide safety review built in.
Both visits end the same way: a new filter, a system tested end to end, and a summary of anything found, from a minor adjustment made on the spot to a part worth watching next season.
Between Visits: Filters, Clearance, and Settings
A little homeowner discipline makes each professional visit go further. On filters: check monthly, replace every one to three months, and buy by the multipack so there is no excuse. On clearance: the outdoor condenser needs free airflow, so rake back leaves, trim back plants, and leave a couple of feet of open space on all sides. On settings: program the thermostat to a steady schedule and resist big swings; deep recovery runs are the hardest work your equipment does. Five minutes a month makes a real difference.
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.
Most manufacturer warranties on furnaces and air conditioners require proof of regular professional maintenance as a condition of coverage. If a covered part fails and the maker asks for service records that do not exist, a claim worth thousands can be denied over paperwork worth a fraction of the part. Keep your invoices, book service at least annually, and the warranty you paid for stays enforceable.
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.

The benefits are cumulative, so the best day to start is whatever today is. Lower energy bills arrive within the first season, fewer breakdowns follow, and a longer equipment lifespan is the long game that saves the most.
