Common problems

## Sound familiar?

ac\_unit

### AC failed during last summer's first heat wave

A neglected capacitor or refrigerant low on charge will hold through spring but fail under the load of a 35-degree July afternoon. Annual tune-ups catch those early.

water\_drop

### House cools but still feels humid and clammy

A dirty evaporator coil reduces dehumidification. Cleaning restores the coil's ability to pull moisture from the air, not just lower the temperature reading.

thermostat

### Energy bills are climbing despite the same usage

Clogged condenser coil fins force the compressor to work harder and longer. Cleaning restores full heat rejection efficiency and can meaningfully reduce summer hydro costs.

## What does an annual AC tune-up include?

Best HVAC Toronto’s annual AC tune-up is a structured maintenance visit covering every component that affects cooling efficiency, dehumidification, and reliability through the summer. We schedule most spring tune-ups between April and May, when booking availability is good and your system is not yet under peak cooling load. The visit typically runs 60 to 90 minutes, and our TSSA-certified team works through a fixed checklist so nothing is left to discretion or skipped under time pressure.

Every finding, measurement, and completed step is recorded on a written service report you keep at the end of the visit. That document supports manufacturer warranty claims, is accepted by every major brand we service, and is useful if an inspector or future buyer asks about the maintenance history.

### What we check, clean, and measure on every visit

**Condensate line inspection and clearing.** The condensate drain carries moisture pulled from the air during cooling. A blocked line overflows into the air handler drain pan, and in homes where the furnace and AC share the same cabinet, overflow reaches the furnace control board directly below. We clear the drain line, inspect the pan, and check the condensate pump if your system has one.

**Evaporator coil cleaning.** The evaporator coil sits inside the air handler and is where refrigerant absorbs heat from your home’s air. A coil coated with dust and biological growth reduces both cooling capacity and dehumidification. Our full-service tune-up includes a coil cleaning that restores airflow and the coil’s ability to remove moisture from the air, not just drop the air temperature.

**Condenser coil cleaning.** The condenser coil sits inside the outdoor unit and is where refrigerant rejects heat to the outside air. Over the winter and early spring, grass clippings, cottonwood seed, and urban particulate clog the coil fins and reduce heat rejection capacity. A blocked condenser forces the compressor to run hotter and longer, raising electricity costs and shortening compressor life. We rinse and brush the fins to restore full capacity.

**Refrigerant subcooling and superheat readings.** Refrigerant does not get consumed in normal operation. If the charge is low, there is a leak. Our technicians measure subcooling at the condenser outlet and superheat at the suction line with calibrated digital gauges, then compare both values against the manufacturer specification. These readings are recorded on the service report, giving you a documented baseline to compare year over year.

**Capacitor microfarad test.** The run capacitor starts and sustains the compressor and condenser fan motor. Capacitors degrade over time and lose microfarad rating before they fail completely. A capacitor reading at 80 percent of nameplate value will hold through a cool spring day and fail under peak load on a 35-degree afternoon in July. We test the capacitor with a meter and advise if it is approaching the replacement threshold.

**Thermostat calibration and set-point verification.** We confirm that the thermostat set-point matches actual room temperature and that staging settings are configured correctly. A thermostat reading two degrees low causes short-cycling and poor dehumidification. Smart thermostat schedules and cooling stages are reviewed and adjusted if needed.

**Electrical connections.** We inspect and tighten connections at the disconnect box, contactor, and capacitor terminals. Loose connections under load arc and burn, which can damage control boards and create a fire risk at the outdoor disconnect.

**Airflow measurement at supply registers.** We measure supply air temperature and, where access allows, airflow in CFM. A narrowing temperature split compared to the previous season suggests a dirty evaporator coil or a developing refrigerant issue, allowing us to catch it early before it becomes a mid-summer call.

## Why annual spring AC maintenance matters for Toronto homes

Toronto’s cooling season runs from late May through September, with the worst heat waves concentrated in July and August. Most catastrophic mid-summer failures are preceded by months of slow degradation: a capacitor drifting below spec, coil fins increasingly restricted, or refrigerant slightly low from a hairline leak in the evaporator coil. A spring tune-up in April or May catches all three conditions before they become an emergency call on a night when same-day availability is gone and the phone line is full.

Annual maintenance also protects your warranty. Most manufacturers require documented service annually as a condition of coverage. A compressor warranty for five to ten years provides no benefit if the claim is denied for a gap in maintenance records. Our written service record is accepted by Lennox, Carrier, Trane, Bosch, Napoleon, York, and every other major brand in our service area.

For homes with older R-410A systems, documenting refrigerant readings annually is particularly useful as R-410A availability tightens over time. If the subcooling or superheat readings shift year over year, you have early evidence of a slow leak worth investigating before it becomes a significant refrigerant loss or a compressor failure.

If your tune-up does turn up a repair, our technicians carry the most common parts on the van. Run capacitor replacements, contactor swaps, and condensate pump replacements are typically completed on the same visit. Larger repairs are quoted in writing before we proceed. If you need emergency service at any hour, call our 24/7 line at 647-254-4113.

FAQ

## AC Tune-Up questions, answered

### What does an AC tune-up include?

expand\_more

Our annual AC tune-up covers condensate line inspection and clearing, evaporator coil inspection and cleaning, condenser coil cleaning, refrigerant subcooling and superheat readings, capacitor microfarad testing, thermostat calibration, electrical connection inspection, and airflow measurement at the supply registers. You receive a written service record with all findings at the end of the visit.

### How much does an AC tune-up cost in Toronto?

expand\_more

Our AC tune-up visits run $150 to $220 per visit. The standard spring inspection starts at $150. The full-service visit, which adds evaporator and condenser coil cleaning, airflow measurement, and electrical tightening, is $190. Bundle with a furnace tune-up for a reduced combined rate. Any repair found during the visit is quoted in writing before we proceed.

### When should I book my annual AC tune-up?

expand\_more

We recommend booking in April or May before the first heat waves of the year. Spring timing lets you secure an appointment without the urgency of a no-cooling call during a heat wave, and your system starts the season freshly serviced. We also accept tune-up calls through the summer if your AC is showing early signs of trouble such as weak cooling or unusual noise.

### How often should my air conditioner be serviced?

expand\_more

Once a year is standard, and most manufacturers require documented annual service as a condition of the warranty. Annual maintenance catches slow refrigerant leaks, capacitors drifting below spec, and coil buildup before they become failures during a heat wave.

### Can a spring tune-up prevent a mid-summer breakdown?

expand\_more

Significantly. The most common causes of summer AC failures are run capacitors at or past their rated microfarad value, low refrigerant from a slow leak, and condenser coils too clogged to reject heat properly. A spring tune-up tests the capacitor, checks the refrigerant charge, and cleans the coils before any of those becomes an emergency.

### Will you check my refrigerant level during the tune-up?

expand\_more

Yes. Our technicians measure subcooling and superheat with digital refrigerant gauges and compare both against the manufacturer specification. Refrigerant does not get consumed in normal operation, so if the charge is low there is a leak. We document the readings and advise on next steps if top-up or leak detection is indicated.

### Do you also tune up ductless mini-split systems?

expand\_more

Yes. Mini-split tune-ups cover filter cleaning, indoor and outdoor coil inspection, condensate drain check, refrigerant pressure readings, and fan motor inspection. The scope and pricing are comparable to a central AC tune-up. Call 647-254-4113 for details specific to your system.

### Can I bundle an AC tune-up with a furnace tune-up?

expand\_more

Yes. Booking both together in one visit or the same season earns a bundle discount. A furnace tune-up in the fall and an AC tune-up in the spring is the most complete annual maintenance approach for your HVAC system. Call 647-254-4113 to ask about current bundle pricing.
