AC Tune Up
London Ontario 2026
A failing capacitor, dirty coil, or low refrigerant charge will not announce itself until your AC stops working on London Ontario’s hottest day. Hawana’s 18-point AC tune-up catches every developing fault in April — before the first 30°C day, before emergency repair queues fill up, and while a repair is still a planned expense instead of a crisis.
Why April is the Right Time for an AC Tune Up in London Ontario
Three reasons professional HVAC technicians and smart homeowners always book their AC service in spring, not summer.
London Ontario Hits 30°C+ by June
Environment Canada data shows London Ontario regularly sees its first 30°C day between late May and mid-June. A tune-up booked in April gives time to repair any issues found — capacitor, refrigerant charge, coil cleaning — before that first heat event. A tune-up booked in July means your system has already been running stressed for weeks.
Technician Availability Is Tightest in July–August
During London Ontario’s hottest weeks, every HVAC company’s schedule fills with emergency repairs. Same-day tune-up bookings are not available — customers who didn’t book in spring wait 3–7 days for service. April bookings get the appointment time you want, not the one that’s left.
Planned Repairs Cost Less Than Emergency Ones
A capacitor found during a spring tune-up costs $100–$200 to replace on a scheduled visit. The same capacitor that fails at 9pm on a 35°C Friday in July is still $100–$200 for the part — but the context is an emergency call, a stressed household, and no cold air until the technician arrives. Hawana doesn’t charge overtime, but most HVAC companies in London Ontario do.
Signs Your London Ontario AC Needs a Tune Up Right Now
These symptoms signal developing faults that a spring tune-up will catch — before they become mid-summer emergencies.
AC runs longer than it used to
If your system runs continuously but the house takes longer to cool than last summer, you likely have a refrigerant undercharge, dirty coil, or a capacitor weakening. All caught in an 18-point inspection.
⚠ Book a tune-up this weekClicking or humming on startup
A clicking sound when the outdoor unit tries to start — followed by a hum but no operation — is a classic failing capacitor or contactor symptom. The capacitor is giving out. It will fail completely, usually on a hot day.
⚠ Call now — imminent failureWater dripping near the indoor unit
The condensate drain line is partially or fully blocked. London Ontario’s moderately hard water deposits calcium in these lines. A blocked drain triggers the safety float switch — your AC shuts off. Clearing takes minutes during a tune-up.
⚠ Clear at first tune-upElectricity bill higher than last year
An AC running at reduced efficiency — dirty condenser coil, low refrigerant, or a failing compressor — works harder and runs longer for the same cooling output. A tune-up that restores efficiency often saves more than its $119 cost in electricity over one summer.
⚠ Efficiency loss is measurableNo professional service in 12+ months
Manufacturers require annual maintenance to keep warranties valid. More practically: a furnace/AC system that has not been serviced in over a year has an unknown number of developing issues. Annual inspection is the only way to know what you’re actually working with.
⚠ Warranty may be voidedCottonwood season approaching
London Ontario’s cottonwood trees release seeds in May through early July that clog outdoor condenser coils faster than any other debris. A tune-up that includes condenser coil cleaning in April, before peak cottonwood season, maximizes cooling capacity when temperatures are highest.
⚠ Clean before cottonwood seasonHawana’s 18-Point AC Tune Up Checklist — London Ontario

How to Prepare Your AC for Summer in London Ontario
What to do before the technician arrives — and what we handle when we get there.
Replace Your Filter
Install a fresh 1-inch MERV 8 filter before the technician arrives. A clean filter means accurate airflow measurements and a coil that doesn’t have to fight restricted airflow.
Clear Around the Outdoor Unit
Remove leaves, debris, and cut back any shrubs to 2 feet of clearance. Do not cover the unit — this restricts airflow year-round.
Technician Arrives
A TSSA certified Hawana technician arrives on time with the tools and parts needed. The 18-point inspection takes 60–90 minutes on most London Ontario systems.

Any issues found are explained clearly. A written repair quote is provided before any additional work begins. No surprise charges.
Service Record
A written service record is provided after every visit — what was inspected, what was found, what was done. Valid for warranty requirements and landlord documentation.

His approach to annual maintenance is straightforward: test everything that commonly fails, report honestly what is found, fix what needs fixing at plan member prices, and tell you when a system is approaching end of life so you can plan rather than react. He carries the full range of common AC parts on every service vehicle so most repairs found at a tune-up are completed the same visit.
AC Tune Up Reviews — London Ontario

“Booked Hawana for an AC tune-up in April on our Riverbend home. They found a capacitor at the low edge of spec — not failed yet, but close. Replaced it for $150. Two weeks later on the first 30 degree day, our AC ran perfectly while two neighbours were calling emergency repair companies. Best $119 I’ve spent.”
“Signed up for the Total Home Plan after our AC tune-up. Abdullah spent over an hour — checked everything including refrigerant pressures and ran the full cooling cycle. Found refrigerant slightly low and cleared a partially blocked condensate drain. Six weeks later on a 32 degree day, AC ran perfectly. The peace of mind is worth every dollar of $279 per year.”
