AC Repair Service in GTA


Common AC Issues We Repair

Not sure if your system needs a repair or just a tune-up? Here are the signs your AC unit is struggling:

1. Not Cooling Properly

This is the number one complaint we hear from customers across the GTA. If your home stays warm no matter how low you set your thermostat, your unit may have a clogged air filter, a refrigerant leak, dirty condenser coils, or a failing compressor. We’ll run a full diagnostic to get to the root cause.

2. Blowing Warm Air

It’s one of the most frustrating problems—your AC is running, but warm air is blowing through your vents. This usually means low refrigerant, a blocked compressor, or thermostat issues. We’ll isolate the cause and get the cold air flowing again.

3. Leaking or Frozen Coils

Water around your indoor unit or frost on your evaporator coils indicates your system is overworking. This can be due to restricted airflow, dirty filters, or refrigerant issues. Left alone, it could lead to serious compressor damage.

4. Weak Airflow

When airflow is poor, it usually means your blower motor or fan isn't working at full capacity. This reduces comfort and stresses your AC system, potentially leading to higher energy use and more frequent breakdowns.

5. Thermostat Malfunction

The thermostat controls your home’s entire climate. If it’s not reading temperatures accurately or fails to communicate with your system, your AC may short cycle or fail to start at all.

6. Unusual Noises

Air conditioners should hum—not rattle, buzz, or clang. If you’re hearing strange sounds, it could mean loose parts, a bad motor, worn belts, or failing electrical components. Don’t ignore the noise—it can become costly.

7. Frequent Cycling

Short-cycling, or constant on-off cycling, stresses your AC and leads to high hydro bills. This can result from a miscalibrated thermostat, electrical issue, or even an oversized system.

8. Bad Odours or Poor Indoor Air Quality

Your AC should improve your indoor air—not make it worse. If you notice musty smells, increased humidity, or allergy symptoms, your system might need a thorough cleaning or UV light upgrade.

Our Process: AC Repair in GTA



At HVAC Group, we make repairs simple, transparent, and quick—from first call to final test.

1. Same-Day Booking

AC failure doesn’t follow a schedule—and neither do we. Call us by noon and we’ll often have a technician out the same day. We prioritize urgent calls, especially during peak summer.

2. Thorough Diagnostics

Our technicians don’t guess. We use high-end diagnostic tools to accurately detect issues. Whether it’s airflow testing, refrigerant pressure checks, or thermal imaging, we find the source—not just the symptom.

3. Upfront Pricing

We respect your budget. After diagnosing the issue, we present you with a detailed quote—explaining every part, labour hour, and cost involved before any work begins.

4. Fast, Quality Repairs

We stock our vans with common parts and tools, so we can complete most jobs on the first visit. Whether it’s a faulty capacitor, blown fuse, or dirty coils—we’ve got it covered.

5. Post-Repair Testing

Once repairs are complete, we test the entire system—thermostat control, temperature split, electrical draw, and refrigerant charge. We aim for optimal performance, not just a temporary fix.

6. Customer Walk-Through

You’ll know exactly what we did, why it failed, and how to avoid future problems. We walk you through filter changes, thermostat usage, and system maintenance tips.

When to Repair vs Replace Your AC



It’s the question every homeowner faces eventually. Should you repair or replace your AC? Here’s how we help you decide:

✔️ Choose Repair If:

  • The unit is less than 10 years old

  • The problem is isolated (e.g. fan motor, capacitor, contactor)

  • There’s no history of major breakdowns

  • Energy bills are still reasonable

❌ Consider Replacement If:

  • Your unit is 12–15 years old

  • There are repeated failures (compressor, blower, board)

  • Efficiency is low and repair costs are stacking up

  • You want to upgrade to eco-friendly refrigerants or improve air quality
