AC Maintenance & Tune-Ups
Most AC failures we see in July were preventable in April. The condenser coil that's now caked in cottonwood fluff and reducing efficiency 30%, the capacitor that finally gave up, the refrigerant slow-leak that's been bleeding pressure for two years — all of it would have been caught and addressed in a $180 spring tune-up.
A proper AC tune-up takes 60–90 minutes and includes the things that actually matter: refrigerant pressure check, capacitor and contactor health, condenser coil cleaning, indoor coil inspection, condensate drain clearing, and amp draw testing on the major motors. Same flat price every visit. Pre-season scheduling means we're not stretched thin during the July rush.
When to book your AC tune-up
Annual is the right cadence. Earlier matters in some scenarios:
- Before each cooling season — April or early May. Pre-season scheduling is easier and pricing is often better than peak-season service.
- After a season the AC ran heavily — if the AC ran constantly through a hot summer, components took more wear than usual.
- If the AC is over 8 years old — annual tune-ups become more important as systems age, since wear-induced failures become more likely.
- After buying a home with central AC — get it inspected within the first month, regardless of when the previous owner last serviced it.
- If the AC is running but not cooling well — could be refrigerant low (leak somewhere), fouled condenser coil, or compressor wear. Worth diagnosing before peak summer.
- If you've noticed strange noises or smells when the AC starts up — a tune-up will diagnose; ignoring tends to make repairs more expensive later.
What's actually included
A real tune-up versus a quick visual check:
- 01
Refrigerant pressure check
Suction and discharge pressures verified against manufacturer spec for outdoor temperature. Low refrigerant indicates a leak — we identify the source rather than just topping up. (Refrigerant doesn't 'get used up'; if you're low, there's a leak.)
- 02
Electrical components
Capacitor health (#1 most common AC failure when it gives up), contactor inspection, wiring connections checked for corrosion or looseness. Compressor amp draw tested against rated specs.
- 03
Coil cleaning
Outdoor condenser coil cleaning — this is where most efficiency loss happens. Cottonwood, dust, dryer lint, and grass clippings clog the fins and reduce heat rejection. Indoor evaporator coil inspected and cleaned if accessible.
- 04
Drainage and controls
Condensate drain line cleared (clogged drain lines cause water leaks at the indoor unit and are responsible for many summer service calls). Thermostat calibration verified. Filter replaced.
- 05
Walkthrough
Quick summary of what we found, what's running well, and any components on the watch list. We don't manufacture problems — if everything's healthy, we tell you so and don't pad the visit with unnecessary recommendations.
What an AC tune-up costs in Halton Hills
Standard AC tune-up: $139–$199 depending on system type and accessibility. Heat pump tune-ups (which include both heating and cooling components) run $179–$249.
Flat pricing every visit. We don't run $39 loss-leader tune-ups followed by aggressive replacement quotes. Avoid contractors who do — that pricing model only works if they recoup margin through inflated 'repairs' during the visit.
Annual maintenance plans (combining spring AC + fall furnace tune-ups) are typically a better value if you have both heating and cooling systems — see our maintenance plans.
AC Tune-Up questions
How often should I get an AC tune-up?
Annually, in spring before the cooling season starts. Older units (10+ years) sometimes warrant inspection again mid-season if they ran heavily through July and August.
Is the $39 AC tune-up special legitimate?
Almost never — at $39, the contractor is losing money on the visit itself, recouping it by finding things to fix or replace. The actual cost of a properly-equipped technician's time, vehicle, and equipment is closer to $150/hour. A real tune-up takes 60–90 minutes. Do the math. The $39 specials tend to come paired with aggressive 'repair' recommendations that the homeowner can't easily verify.
Can I do an AC tune-up myself?
Some of it. Clearing debris around the outdoor unit, hosing down the condenser coil from the outside (without bending fins), clearing the condensate drain line, and changing filters are all worthwhile DIY tasks. The refrigerant pressure check, capacitor testing, and coil-fin straightening require specific tools and training. Refrigerant work specifically is illegal without certification — DIY refrigerant top-ups are a federal regulatory issue.
When's the best time to book?
March through April. By May, demand picks up as homeowners notice their AC isn't cooling properly. By June, you're competing for slots with people whose ACs already failed. Pre-season pricing is also typically lower during the off-peak window.
Will the tune-up actually save me money?
Modest direct savings — typically 5–10% on cooling costs from restored efficiency, $50–$150 a year for most homes. The bigger value is in catching capacitor wear, refrigerant slow-leaks, and contactor degradation before they become mid-July emergency repairs (which cost more, plus the discomfort of going without AC during a heatwave).
Do you service heat pumps under the AC tune-up?
Heat pumps need their own tune-up (slightly different scope and longer visit since they include both heating and cooling components). Most maintenance plans cover heat pumps under a single annual visit rather than separate spring/fall visits.
