Recognize the Warning Signs

Signs You Need Emergency AC Service in Burlington

Not every AC problem is an emergency, but some issues can worsen quickly, affect indoor air quality, or pose safety risks. If you are experiencing any of the following, call our 24/7 emergency line immediately.
AC Blowing Warm Air
If your system is running but only pushing warm or room-temperature air, you may have a refrigerant issue, failed compressor, or a frozen evaporator coil.
AC Not Turning On
A system that will not start at all despite a working thermostat and power supply indicates an electrical fault, failed capacitor, or tripped safety switch.
Refrigerant Leak
Hissing sounds, ice buildup on refrigerant lines, or a sudden drop in cooling performance can signal a refrigerant leak. This requires prompt attention both for system performance and environmental compliance.
Burning Smell or Electrical Odour
Any burning smell coming from your AC unit or air vents is a potential electrical hazard. Shut the system off immediately and call for emergency service.
Frozen Evaporator Coil
Ice forming on the indoor unit or refrigerant lines means your system is not operating correctly. Running a frozen unit can cause lasting compressor damage.
Loud or Unusual Noises
Grinding, banging, squealing, or rattling sounds from your AC unit often indicate a failing motor, loose components, or a damaged compressor that will worsen without repair.
Water Leaking Indoors
A blocked condensate drain can cause water to back up into your home. Left unaddressed, this can cause water damage, mould growth, and structural issues.
Short Cycling
If your AC turns on and off repeatedly within short intervals without reaching the set temperature, it signals an underlying problem that places excessive strain on the system.

Our Process

What Happens When You Call for Emergency AC Service

We know you want your cooling system fixed, not a sales pitch. Here is exactly what to expect from the moment you call until your AC is running again.
1
Speak With Our Team
When you call (289) 812-7854, you will speak directly with a member of our service team, not an answering service. We will ask a few quick questions about your air conditioner, the symptoms you are experiencing, and whether there are any immediate safety concerns such as burning smells or electrical issues. This helps us prepare the right parts before arriving.
2
Priority Scheduling
Emergency cooling calls are given priority scheduling. We dispatch the nearest available licensed technician and provide you with an estimated arrival window. We serve all Burlington neighbourhoods and the surrounding Halton Region, so response times are kept as short as possible.
3
On-Site Diagnosis
Our technician performs a complete system inspection upon arrival, checking electrical components, refrigerant charge, airflow, thermostat operation, and mechanical condition. We identify the root cause of the problem, not just the symptom, so the repair holds.
4
Upfront Repair Options
Before any work begins, you receive a clear explanation of the issue, available repair options, and the cost of each. No hidden fees. No work begins without your approval. This is how we build long-term trust with Burlington homeowners.
5
Immediate Repair
Most emergency AC repairs are completed during the first visit. Our vehicles are stocked with the most common replacement parts including capacitors, contactors, fan motors, blower components, refrigerant, and thermostats, reducing wait times and avoiding unnecessary follow-up appointments.
6
System Testing
After the repair, we test your entire system including cooling output, airflow through vents, thermostat calibration, and overall performance before we consider the job complete. You should be able to feel the difference before our technician leaves your home.
7
Recommendations & Prevention Advice
If we notice additional concerns such as a coil nearing end of life, slightly low refrigerant charge, or a filter restricting airflow, we will let you know. You are under no obligation to act immediately, but having the information helps you plan ahead and avoid repeat emergencies.

Our 24/7 team is standing by. Most repairs are completed on the same visit.
Before You Call

Emergency AC Troubleshooting Checklist

Answer a few quick questions about your air conditioner and our free tool will help you identBefore calling for emergency service, run through these quick checks. Occasionally a simple issue such as a tripped breaker or wrong thermostat setting can restore cooling without a service call. If none of these resolve the problem, call us immediately.ify what might be wrong, whether it needs immediate attention, and what to do next.
Check your thermostat is set to COOL and the temperature is below current room temperature
Check that the thermostat is set to AUTO, not just FAN
Check your electrical panel for a tripped breaker labelled “AC,” “Air Handler,” or “Furnace”
Check the AC disconnect box near the outdoor unit has not been switched off
Check that the indoor air handler power switch (looks like a light switch) is turned on
Replace your air filter if it has not been changed in the past 2 to 3 months since a clogged filter can cause the system to freeze up
Check the outdoor condenser unit is clear of debris, grass, or objects blocking airflow
Check that all supply and return vents in your home are fully open and unobstructed
If ice is visible on the indoor unit or refrigerant lines, turn the system OFF and call us, do not run a frozen system
If you smell burning or hear a loud bang, shut the system off at the breaker and call immediately
If you have completed these checks and your AC is still not cooling, contact Burlington Heating and Cooling atĀ (289) 812-7854. Our team is available 24/7.

Common AC Problems

Emergency AC Problems We Repair in Burlington

Our technicians are experienced with all types of central air conditioning failures. Here are the most common emergency AC repairs we handle across Burlington.
Failed Capacitor
The most common reason an AC will not start in summer. Capacitors start and run the compressor and fan motors. When they fail, the system will hum but not start, or will not start at all.
Bad Contactor
The contactor is a switch that controls power to the compressor and fan. When it fails or becomes pitted from regular use, the outdoor unit may not respond to the thermostat’s signal to cool.
Low Refrigerant / Refrigerant Leak
Low refrigerant means insufficient cooling capacity. Refrigerant does not run out on its own. A low charge always indicates a leak that must be found, sealed, and recharged by a certified technician.
Frozen Evaporator Coil
Caused by restricted airflow (dirty filter, blocked vents) or low refrigerant. The coil freezes over and the system loses its ability to cool. The system must be shut off to thaw before repair can begin.
Fan Motor Failure
If the outdoor fan is not spinning, the condenser cannot release heat, causing the system to overheat and shut down on high-pressure safety. The compressor can suffer permanent damage if run in this condition.
Blocked Condensate Drain
During cooling, AC systems produce condensation that drains away. When the drain line clogs with algae or debris, water backs up into the air handler, often causing water damage to ceilings or floors below.
Control Board or Thermostat Failure
A failed control board or thermostat can cause a system to not start, short cycle, or behave erratically. Diagnosis requires testing individual circuits to rule out other faults before replacing the board.
Compressor Issues
The compressor is the heart of your AC system. Hard-starting, overheating, or tripping the breaker repeatedly are warning signs. Early intervention can often prevent full compressor replacement, which is the most expensive AC repair.

Our licensed technicians can diagnose and repair any AC issue, same day, with parts on the vehicle.

Common Questions

Frequently Asked Questions About Emergency AC Service in Burlingto

Response times vary depending on the time of day and current demand, especially during heat waves when emergency calls are high across the city. We prioritize emergency cooling calls and aim to have a technician on-site as quickly as possible. When you call, we will give you an honest estimated arrival window. For critical situations such as households with infants, seniors, or medical needs, please let us know so we can prioritize accordingly.

We will be transparent about any after-hours or weekend service charges when you call. We provide the full pricing breakdown before any work begins including service fees and part costs so you can make an informed decision. We never add fees after the work is done.

Run through our troubleshooting checklist above and check the thermostat settings, breaker panel, and air filter. If none of those steps restore cooling, call (289) 812-7854 immediately. While waiting for service, close blinds and curtains on sun-facing windows, move to the lowest level of your home (basements are naturally cooler), use fans to improve air circulation, and stay hydrated. If anyone in the household is elderly, very young, or has a medical condition affected by heat, consider a temporary move to an air-conditioned space.

In most cases, yes. Our vehicles are stocked with the most common replacement parts for residential AC systems including capacitors, contactors, fan motors, refrigerant, and thermostat components. The majority of emergency repairs are completed during the initial visit. If a part is not on the vehicle or your system requires a less common component, we will let you know immediately and arrange to return as soon as the part is available.

Costs depend on the type of repair, the parts required, and the time of service. Common repairs such as a capacitor or contactor replacement typically range from $150 to $350 in parts and labour. More involved repairs such as fan motor replacement, refrigerant recharge, or control board issues can range from $300 to $700 or more. We provide a firm upfront quote before any work begins, so you will always know the cost before approving the repair. Use our freeĀ AC Repair Cost CalculatorĀ for an estimate.

There are several possible causes: low refrigerant due to a leak, a frozen evaporator coil, a dirty condenser coil on the outdoor unit preventing heat rejection, a failed compressor, or a faulty reversing valve on heat pump systems. The thermostat should also be checked to confirm it is set to COOL and not FAN-only mode. A technician will need to diagnose the specific cause. Do not continue running the system if you suspect a refrigerant leak or frozen coil.

A commonly used guideline in the HVAC industry is the “5,000 rule”: multiply the age of the unit in years by the estimated repair cost. If the result exceeds $5,000, replacement is often the more economical long-term choice. For example, a 12-year-old unit requiring a $600 repair results in 7,200, which suggests replacement may be worth considering. Our technicians will give you an honest assessment based on the condition of your system. You can also explore ourĀ AC Replacement pageĀ for more guidance.

Yes. Our technicians are experienced with all major residential and light-commercial air conditioning brands, including Carrier, Lennox, Trane, Goodman, York, American Standard, Mitsubishi, Daikin, Fujitsu, Bryant, and others. We repair central AC systems, ductless mini-splits, and heat pump systems in cooling mode.

The single most effective step is annual preventive maintenance, ideally scheduled in spring before the cooling season begins. During a tune-up, a technician cleans the coils, checks refrigerant charge, tests electrical components, clears the condensate drain, lubricates moving parts, and identifies parts showing signs of wear before they fail. Most AC emergencies in the summer are preventable with a spring maintenance visit. Learn more on ourĀ AC Maintenance page.

Yes. If your AC system has failed but the furnace and air handler are otherwise functional, you can set your thermostat to FAN ON (rather than AUTO) to circulate air throughout your home. This will not cool the air, but it will improve comfort by keeping air moving. Do not run the AC system itself if you have been told the compressor may be at risk, if you have a frozen coil, or if there is a suspected refrigerant leak.
