What a complete AC tune-up covers
Did you know?
According to ASHRAE, dirty condenser coils can reduce an AC system’s efficiency by up to 30 percent. In a typical GTA home running a 3-ton system, that efficiency penalty can add $100 to $200 to the annual hydro bill. A coil cleaning during a spring tune-up is often the single action with the highest immediate return on a dollar-for-dollar basis.
People often ask: does skipping a tune-up year really matter?
One missed year is usually fine. Two or three in a row starts to show up as accelerated wear on capacitors and contactors, reduced refrigerant circuit efficiency, and coils that are harder to clean because the buildup is thicker. The cost of catching up on neglected maintenance is almost always higher than the cost of steady annual service.
What a tune-up does NOT include
What does an AC tune-up cost in the GTA?
Pricing note: The cost ranges below are estimates based on typical GTA market rates as of 2026. Prices vary by company, what is included in the service, and whether any parts are replaced during the visit. Always ask what is included before booking.
| Service | Typical cost (GTA 2026) | Notes |
|---|---|---|
| Full spring tune-up | $100 to $175 | Should include coil clean, refrigerant check, capacitor test, drain flush |
| Capacitor replacement (if needed) | $150 to $350 | Often done during tune-up visit; cheaper than emergency call |
| Refrigerant recharge (if low) | $250 to $600 | Separate from tune-up; requires finding and fixing leak first |
| Contactor replacement (if needed) | $150 to $300 | Common replacement; often proactive during tune-up on older units |
| Discount tune-up specials | $49 to $79 | Usually filter swap and visual only. Not a full service. |
The difference between a $79 special and a $150 full service is almost always coil cleaning and a proper refrigerant check with gauges. If those are missing, you have not had a real tune-up.
Pro tip
When you call to book a tune-up, ask the company if they perform a refrigerant check with manifold gauges and test the capacitor microfarad rating with a meter. If the answer is vague or they say they just do a visual check, they are not doing a full tune-up. A thorough technician will have gauges and a capacitor tester on every truck.
Save your money
Some HVAC companies offer a maintenance agreement that includes an annual spring AC tune-up and a fall furnace inspection for a flat annual fee of $200 to $350. If you have two systems to maintain and you are booking separate appointments anyway, a maintenance plan often works out cheaper per visit and prioritizes you for faster service in the busy summer months.

Frequently asked questions
How often should I get an AC tune-up?
Once a year, ideally in April or May before the cooling season. Annual service keeps the system running at close to its rated efficiency and gives a technician the chance to catch small problems before they become failures in the middle of July. Systems older than 10 years benefit most from consistent annual service.
How much does an AC tune-up cost in the GTA?
A thorough spring tune-up in the GTA typically runs $100 to $175. That range covers coil cleaning, a refrigerant pressure check with gauges, capacitor and contactor testing, condensate drain flush, and a safety check. Advertised specials under $80 usually do not include all of these steps. Ask specifically what is included before booking.
Can I do an AC tune-up myself?
Some tasks are DIY-friendly: cleaning around the outdoor unit, replacing the air filter, and flushing the condensate drain with diluted bleach. The refrigerant check, electrical connection tightening, and capacitor testing require a licensed TSSA-certified technician. A DIY visual check is a useful supplement to professional service, not a replacement for it.
Does a tune-up include refrigerant top-up?
No. A tune-up includes a refrigerant pressure check to see if levels are correct. If the system is low, that means there is a leak. Finding the leak, repairing it, and recharging are separate work billed in addition to the tune-up. Refrigerant does not deplete naturally. Low pressure always means a leak.
What happens if I skip the spring tune-up for a few years?
The most common consequences are accelerated capacitor and contactor wear (leading to summer breakdowns), reduced efficiency from dirty coils, and a higher chance of missing a refrigerant leak before it causes compressor damage. None of these are guaranteed, but the risk compounds over time. A system that has not been serviced in three or more years is a good candidate for a catch-up maintenance visit before the next cooling season.
