Weak run capacitor
The most common no-cool cause. We measure microfarads against the label and flag ones that are drifting before they leave the compressor unable to start.

AC Preventive Maintenance That Stops Failures Early
Most air conditioner breakdowns give warning signs weeks ahead. Preventive maintenance is how we spot them while the fix is still small.
- Electrical parts tested
- Coils and drains cleaned
- Refrigerant performance checked

Overview
What AC preventive maintenance actually prevents
A tune-up is often sold as a quick hose-down of the outdoor unit. Real AC preventive maintenance is different: it is a set of measurements that tell us which part is closest to failing. A run capacitor that has drifted below its rating, a contactor with pitted points, a fan motor drawing more amps than it should, a coil that has lost a third of its airflow to dust. None of these stop the system today, but each one is a likely cause of a no-cool call during the hottest week of the year.
We test, record and compare. If something is wearing out, we tell you what it is, how urgent it is and what it would cost to replace now versus waiting. You decide. Many homeowners pair this visit with their furnace service in the fall, since the indoor coil and blower are shared.
Failures we try to head off
These are the usual suspects behind summer breakdowns, and each one can be caught early.
Worn contactor
Burnt or pitted contacts cause chattering, hard starts and eventually a unit that will not turn on or will not turn off.
Frozen indoor coil
Low airflow or low refrigerant makes the coil ice up. We check static pressure, filter condition and the temperature split across the coil.
Condensate overflow
Algae and sludge build up in drain lines over the winter. Flushing them in spring prevents water stains on ceilings and floors.
Slow refrigerant leak
Superheat and subcooling readings that change from year to year point to a small leak long before the system stops cooling entirely.
Tired fan motors
Bearings that whine or motors running hot get noted, so a fan replacement can be planned instead of rushed.
Included
Included in a preventive maintenance visit
- Capacitor, contactor and wiring inspection
- Motor amperage compared with nameplate ratings
- Outdoor coil rinsed and fins straightened
- Indoor coil and drain pan inspected
- Condensate line flushed and trap checked
- Superheat and subcooling measured
- Thermostat calibration and cycle test
- Written notes on parts that are wearing
How it works
How the visit runs
- 1
Shut down safely
We disconnect power at the outdoor disconnect and confirm it is dead before opening any panels.
- 2
Clean and inspect
Coils, drain, fan blades and electrical compartment are cleaned and looked over for wear, corrosion or rodent damage.
- 3
Run and measure
With the system cooling, we take electrical and refrigerant readings and the supply and return air temperatures.
- 4
Report back
You get a plain summary of the system's condition and any recommendations, ranked by urgency.
Why preventive care with Able Pro
Fewer emergency calls
Replacing a worn part on a calm spring day beats losing cooling on a 34 degree evening.
Efficiency kept up
Clean coils and correct refrigerant performance let the system move more heat for the same electricity.
No pressure upsell
If everything tests well, we say so. Recommendations come with readings, not scare tactics.
Easy to schedule
Book online or by phone, and pair it with a furnace or heat pump check if you like.

Questions homeowners ask us
Still unsure? Call (236) 222-2222 and talk it through with us.
Is preventive maintenance worth it on a newer air conditioner?
Yes. New systems still collect dust and debris on the coils, and many manufacturers list annual servicing in their warranty terms. Early visits also give us baseline readings to compare against in later years.
What month should I book AC preventive maintenance?
April and May are ideal. The system has been sitting all winter, and you want any issue found before the first heat warning rather than during it.
Can I do some of the maintenance myself?
You can change the filter every one to three months, keep plants and leaves at least half a metre away from the outdoor unit and gently hose the coil from the inside out with power off. Electrical and refrigerant checks should be left to a technician.
Will you add refrigerant during the visit?
Only if readings show it is low, and we will tell you first. A system that needs refrigerant has a leak somewhere, so we will also explain options for finding and repairing it rather than topping it up every year.
Does preventive maintenance cover heat pumps too?
Yes. A heat pump has the same parts plus a reversing valve and defrost controls, which we also test. Because it runs year round, we recommend a spring and a fall visit.
