How often should I service my air conditioner

Air conditioners should be professionally serviced once per year, ideally in late spring before the cooling season begins. This annual maintenance helps ensure efficient operation, prevents breakdowns during hot weather, and extends your system's lifespan.

Professional annual service typically includes cleaning the condenser coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing system performance. A trained technician can spot potential issues before they become expensive repairs or leave you without cooling during Ottawa's hottest summer days.

Between professional visits, homeowners should change or clean air filters every 1-3 months during cooling season, keep the outdoor unit clear of debris and vegetation (maintain 2 feet of clearance), and ensure indoor vents aren't blocked by furniture or curtains. These simple steps help your AC run efficiently and reduce strain on the system.

In Ottawa's climate, where air conditioners work hard during humid summers but sit idle for many months, annual servicing is especially important. The freeze-thaw cycles and seasonal debris can affect outdoor units, while indoor components may develop issues during the long off-season. Regular maintenance typically costs $150-$200 but can prevent much more expensive repairs or premature system replacement.

Signs your AC needs immediate attention include weak airflow, warm air from vents, unusual noises, ice formation on the unit, or significantly higher energy bills. Don't wait for your annual service if you notice these issues - addressing problems early prevents more serious damage.

For reliable annual AC maintenance in Ottawa, consider scheduling your service appointment in April or May before the summer rush begins.
