When your air conditioning stops working, every drive becomes uncomfortable, especially during a Peterborough summer. At 4 Aces Auto Centre, our certified technicians diagnose and repair A/C systems on all makes and models, so you stay cool without overpaying for dealer service.
Your vehicle’s air conditioning system gives clear warning signs before it fails completely. Bring your car to 4 Aces if you notice any of the following:
A/C System Diagnosis – from $89
We connect your vehicle to professional diagnostic equipment to measure refrigerant pressure on both high and low sides, test the compressor clutch engagement, inspect belts, hoses, the condenser, and evaporator, and perform electronic leak detection. You receive a written report before any repair work begins.
Refrigerant Recharge (AC Recharge Peterborough)
Low refrigerant is the most common cause of poor A/C cooling performance. We recover any remaining refrigerant, evacuate the system, and recharge to manufacturer specifications using the correct refrigerant type for your vehicle – R-134a (pre-2017 vehicles) or R-1234yf (most 2017 and newer vehicles).
Leak Detection & Repair
Refrigerant doesn’t just disappear – if your system keeps losing charge, there is a leak somewhere. We use UV dye injection and electronic leak detectors to pinpoint leaks in hoses, O-rings, the condenser, evaporator core, or compressor seals. Once found, we repair or replace the faulty component.
Compressor Replacement
The A/C compressor is the heart of the system. When it fails, the entire system stops working. We source high-quality replacement compressors, perform a full system flush to remove contaminants before recharging, and prevent premature damage to the new compressor.
Condenser & Evaporator Service
A damaged or clogged condenser reduces cooling efficiency. A leaking evaporator core causes interior moisture and odours. We inspect, clean, and replace both components as needed.
Cabin Air Filter Replacement
A clogged cabin air filter restricts airflow through the A/C system, forcing it to work harder and reducing cooling. Replacement is quick and inexpensive, and dramatically improves both cooling performance and interior air quality.
Desiccant Filter / Receiver Dryer Replacement
The desiccant filter removes moisture from the refrigerant. Over time it becomes saturated, leading to internal corrosion and compressor damage. We recommend replacement every 2–3 years or whenever the A/C system is opened for major repair.
A/C repair costs vary based on the specific issue. Here are typical ranges at an independent shop like 4 Aces:

The most common causes are: (1) low refrigerant due to a slow leak, (2) a failed compressor clutch, (3) a clogged condenser, or (4) a faulty blend door actuator. A diagnostic at 4 Aces will identify the exact cause within the same visit.
A refrigerant recharge typically costs $120–$280 depending on refrigerant type. Compressor replacement ranges from $700–$1,800. A diagnosis is $89–$149 and is applied to the repair cost when you proceed with us.
In most cases, yes – a broken A/C is not a safety hazard. However, in extreme heat it creates driver fatigue, and some A/C failures (like a seized compressor) can damage the serpentine belt if left too long. We recommend getting it checked promptly.
We recommend an A/C inspection every 2 years, or any time you notice reduced performance. Spring – before summer heat arrives – is the ideal time to book a check.
DIY recharge kits add refrigerant but don’t address the root cause – the leak that caused the loss. Overfilling the refrigerant can damage the compressor. Professional service identifies and fixes the leak before recharging.
The most cost-effective Fleet Services are preventive, not reactive. Around the world, fleets that follow a regular maintenance schedule see fewer breakdowns, better fuel economy, and longer vehicle life.
