From $149/hr + HST

Best value during regular office hours when your AC is not cooling, leaking, freezing, short cycling, or making unusual noises.

Rates can vary by appointment type, access, repair scope, parts, statutory holidays, and current availability. Confirm current pricing when booking.

After-Hours Cooling Help

Available when comfort cannot wait and your central AC, heat pump, or ductless cooling system needs urgent attention.

For after-hours help, call 613-592-5770 and choose the emergency service option.
Common Cooling Problems

AC Problems We Diagnose

A cooling issue can come from airflow, electrical parts, the thermostat, the outdoor unit, the indoor coil, drainage, or the refrigerant circuit. A diagnostic visit helps narrow the cause.

  • Air conditioner running but not cooling the home
  • Warm or lukewarm air from supply vents
  • Frozen evaporator coil or icy refrigerant line
  • Weak airflow from vents
  • Outdoor condenser or fan not turning on
  • System starting and stopping too often
  • Water leaking near the indoor equipment
  • Thermostat, capacitor, contactor, or wiring concerns
  • Breaker trips when cooling starts
  • Heat pump or ductless mini split not cooling in summer mode
Before You Call

What to Tell Our Team

A few details can help us book the correct diagnostic visit and prepare the technician for what is happening at your home.

  • Is the thermostat set to cool and below the room temperature?
  • Is the outdoor fan running, buzzing, silent, or starting and stopping?
  • Do you see ice, water, an error code, or a tripped breaker?
  • Is the issue affecting the whole home or only one zone?
  • Is the system a central air conditioner, heat pump, or ductless mini split?

You do not need to diagnose the problem yourself. The goal is simply to give our dispatch team a clear starting point.

Diagnostic-First Repair

What Happens During an AC Repair Visit?

A good repair visit should not feel like guesswork. We test the system, explain the likely cause, and review the practical options before repair work moves forward.

1. Review the Symptoms

We start with what you are experiencing, such as warm air, strange noises, water leaks, breaker trips, short cycling, or a frozen coil.

2. Test the System

Our technician checks airflow, controls, electrical components, outdoor unit operation, drainage, and refrigerant-related symptoms.

3. Explain the Next Step

You receive clear options for repair, maintenance, or replacement based on equipment condition, repair value, and long-term comfort.

Prevent Bigger Damage

Do Not Keep Forcing a Failing AC to Run

If the breaker trips repeatedly, the outdoor unit buzzes but will not start, the coil is frozen, or you smell something hot or electrical, turn the cooling system off at the thermostat and book a diagnostic visit.

Repeated attempts to force a failing system to run can damage the compressor and make the repair more expensive. A qualified technician should inspect the equipment and recommend the safest next step.

Repair, Maintenance, or Replacement?

Which AC Service Do You Need?

Homeowners often use “AC service” to describe several different situations. The right appointment depends on what the system is doing today.

Book Diagnostic Repair

Your system is not cooling, leaking, frozen, short cycling, tripping a breaker, or making loud mechanical or electrical noises.

Book AC Maintenance

Your system is running, but you want a seasonal tune-up, airflow check, cleaning, and preventative inspection.

Compare Replacement

The AC is older, inefficient, unreliable, or facing a repair that may not deliver good long-term value.

Honest Repair Guidance

Should You Repair or Replace Your Air Conditioner?

The right answer depends on the system’s age, repair history, comfort performance, efficiency, and the cost of the recommended fix. We help you compare the options instead of pushing a one-size-fits-all answer.

Decision Factor Repair May Make Sense Replacement May Be Smarter
System age The AC is newer, maintained, and normally keeps the home comfortable. The system is older, inefficient, or nearing the end of its expected service life.
Repair history This is the first meaningful repair and the issue appears isolated. The AC has needed repeated repairs or tends to fail during hot, humid weather.
Type of issue The repair involves a practical component such as a capacitor, contactor, thermostat, drain, or minor electrical fault. The issue involves major components, repeated failures, poor cooling capacity, or high repair cost compared to replacement value.
Comfort performance The system cooled the home well before the current problem started. The home has weak cooling, uneven rooms, high humidity, or excessive noise even when the AC runs.
Long-term value The repair is affordable and likely to extend useful life without creating a pattern of service calls. Repair money may be better invested into a properly sized central AC, heat pump, or ductless solution with warranty protection.
Systems We Diagnose

Central AC, Heat Pump, and Ductless Cooling Repair

Ottawa homes increasingly use mixed HVAC setups. Proper diagnosis requires knowledge of equipment type, controls, airflow, drainage, and how the home performs during humid summer weather.

Central Air Conditioners

Outdoor condenser, indoor coil, blower, thermostat, electrical components, airflow, drainage, and cooling performance.

Heat Pumps

Cooling mode problems, short cycling, error codes, control issues, refrigerant-related symptoms, and poor summer performance.

Ductless Mini Splits

Zoned comfort problems, drainage issues, error codes, weak cooling, communication faults, and outdoor unit concerns.

For dedicated heat pump information, visit our heat pump repair and heat pump service pages.

Repair FAQs

Air Conditioner Repair FAQs

Do you provide AC repair service across Ottawa?

Yes. AirZone provides diagnostic and repair services across Ottawa, Kanata, Orleans, Barrhaven, Nepean, Gloucester, Stittsville, Riverside South, Kemptville, and nearby communities. We repair central air conditioners, heat pumps, and ductless cooling systems.

Why is my AC running but not cooling the house?

An AC that runs but does not cool may have restricted airflow, a heavily soiled filter, outdoor unit problems, a frozen evaporator coil, a failed capacitor, a thermostat issue, or a refrigerant-related problem. A diagnostic visit allows a technician to test the system and identify the likely cause.

What should I do if my air conditioner is blowing warm air?

First, verify that the thermostat is set to cool and the set point is below the room temperature. Check the furnace filter and clear debris away from the outdoor unit. If the system still blows warm air, turn it off to reduce the risk of damage and book a repair diagnostic.

Can a frozen AC coil be repaired?

A frozen coil is usually a symptom of a larger problem, such as severe airflow restriction, blower issues, coil condition, or a refrigerant concern. Do not scrape the ice. Turn the system off so it can thaw, then book a diagnostic visit so a technician can find the root cause.

Can an electrical or capacitor problem stop my AC from cooling?

Yes. Failing capacitors, burnt contactors, damaged wiring, and faulty thermostat signals can prevent the outdoor condenser from starting or operating correctly. Electrical AC repairs should be handled by a qualified HVAC technician.

Should I repair or replace my broken air conditioner?

Repair often makes sense if the system is newer, well maintained, and the fix is practical. Replacement may be smarter if the unit is older, inefficient, repeatedly failing, or facing a major repair that does not offer good long-term value.

Is this the right page to book seasonal AC maintenance?

No. This page is for active cooling failures and diagnostic repair. If your air conditioner is working properly and you want preventative cleaning and inspection, visit the Air Conditioning Service page.

Do you repair heat pumps and ductless cooling systems?

Yes. AirZone diagnoses and repairs heat pumps and ductless mini split systems, including short cycling, error codes, drainage problems, weak cooling, control issues, and outdoor unit concerns.
