How Much Do AC Repairs Cost in Burlington?

Burlington HVAC repair calls typically start with a diagnostic fee of $89–$150, which covers the technician’s time to diagnose the problem. Some contractors waive this fee if you proceed with the repair. After diagnosis, the total repair cost depends heavily on which component has failed.

Minor repairs — a dirty filter causing a freeze-up, a tripped breaker, a faulty thermostat — are often inexpensive or even DIY-fixable. Major repairs involving refrigerant or compressor failure can approach or exceed the cost of a new system, especially in older units.

Repair or Replace? The Burlington Homeowner’s Guide

The hardest decision in AC ownership: spend money on a repair, or put that money toward a new system instead? There’s no universal answer, but two rules of thumb help most Burlington homeowners reason through it.

📅 The Age Rule

If your AC is 10+ years old, major repairs get harder to justify. A compressor replacement on a 14-year-old unit costs nearly as much as a down payment on a new system — and the unit has limited remaining lifespan regardless.

💲 The 50% Rule

If the repair cost exceeds 50% of what a new comparable system would cost, replacement often makes more financial sense — especially factoring in the improved efficiency and warranty of a new unit.

🔁 The Frequency Rule

One repair in 10 years is normal maintenance. If you’ve had two or more significant repairs in the past three years, something systemic is usually failing. The next repair is probably not the last one.

🌡️ The R-22 Rule

If your AC uses R-22 refrigerant (pre-2010 systems), it’s illegal to manufacture in Canada and expensive to obtain. A leak in an R-22 system is almost always a replacement trigger — the refrigerant cost alone can be $1,000+.

Not sure which applies to your situation? Our Burlington technicians will give you an honest assessment — including when replacement makes more sense than a repair we could perform today.

🔍 Common AC Symptoms & What They Usually Mean

AC not cooling at all:

Tripped breaker, failed capacitor, or refrigerant loss — start with the breaker panel before calling anyone

AC running but not cold enough:

Low refrigerant charge (leak), dirty coils, or undersized unit struggling on peak heat days

Ice forming on outdoor unit or lines:

Usually refrigerant issue or severely restricted airflow — turn off and call a tech

Grinding or screeching noises:

Failing blower motor or fan motor bearing — don’t ignore; running it can destroy the motor

Water leaking inside near air handler:

Blocked condensate drain — often DIY-fixable with a wet-vac and some white vinegar

Short-cycling (on/off every few minutes):

Oversized unit, low refrigerant, or failing thermostat — needs diagnosis

Frequently Asked Questions

What’s included in a Burlington AC service call fee?

Most Burlington HVAC contractors charge $89–$150 for a diagnostic visit. This covers the technician’s travel time and the diagnostic work — identifying the problem, testing electrical components, checking refrigerant pressure, and explaining what’s wrong. Parts and repair labour are quoted separately after diagnosis. Some contractors apply the diagnostic fee to the repair total if you proceed the same day; ask about this upfront.

My AC is low on refrigerant. Is that a leak or normal?

It’s a leak — period. A properly functioning AC is a sealed system that neither gains nor loses refrigerant over time. If a technician tells you your system is “low on refrigerant” and just wants to top it up, ask them to find and fix the leak first. Recharging without finding the leak means you’ll be paying for refrigerant again within 1–3 seasons while the leak worsens.

Can I buy AC parts myself and have a technician install them?

For some parts, yes — capacitors and thermostats are commonly available online and some homeowners purchase them directly. However, refrigerant-related work, electrical panel connections, and anything requiring disconnection of refrigerant lines must be done by a licensed technician. Attempting refrigerant work without certification is both illegal in Canada and potentially dangerous.
