Fast, affordable same-day air conditioner repair in Calgary — from certified HVAC technicians. We respond within hours, not days.
What's Wrong with Your Air Conditioner?
Click your symptom below — our certified technicians can diagnose and repair any AC issue in Calgary the same day you call.
AC Not Cooling / Blowing Warm Air
The most common AC complaint in Calgary. Usually caused by low refrigerant from a leak, a failing compressor, or frozen evaporator coils. Check your filter first — if it’s clogged, replace it. If the problem continues, call us for a same-day diagnosis.
AC Not Turning On
Check your thermostat settings (set to COOL, batteries fresh), your disconnect box outside, and your electrical panel breaker. If all of those are fine and your AC still won’t start, a failed capacitor or contactor is the likely culprit — both are common, affordable repairs.
AC Leaking Water Indoors
Water pooling near your indoor unit usually means a blocked condensate drain line or frozen coils that are thawing. Turn off the unit and call us promptly — continued operation with a blocked drain can cause water damage to your home.
AC Freezing Up / Ice on Unit
Ice on your AC typically means restricted airflow (dirty filter or blocked registers) or low refrigerant. Turn the system off and let it thaw completely before calling us. Running a frozen AC can permanently damage the compressor.
AC Making Strange Noises
Banging or clanking usually means a loose or broken part inside the unit. Squealing often indicates a failing fan belt or motor bearing. Rattling may be loose debris or sheet metal. Don’t ignore unusual sounds — they often signal an issue that gets more expensive if left unrepaired.
High Energy Bills / AC Running Constantly
If your AC is running constantly but not reaching your set temperature, your system is likely low on refrigerant, has dirty coils, or is undersized for your home. Annual tune-ups prevent this — a poorly maintained AC can consume 15–25% more energy than a properly serviced one.
AC Short-Cycling (Turning On and Off)
Short-cycling — when your AC turns on and off every few minutes — stresses the compressor and drives up your energy bill. Common causes include a dirty filter, refrigerant leak, or an oversized system. Remember the 3-minute rule: always wait at least 3 minutes before restarting your AC.
Uneven Cooling / Hot Rooms in Calgary Home
Uneven temperatures throughout your home usually indicate leaky ductwork, blocked registers, or an improperly sized AC system. Our technicians assess airflow and system capacity to find the root cause — not just the symptom.

Should You Repair or Replace Your Air Conditioner in Calgary?
The decision comes down to three factors: system age, repair cost, and energy efficiency. Here’s how to think through it.
Repair Makes Sense When…
- The unit is under 10 years old
- This is your first breakdown
- The repair is a minor component (capacitor, contactor, refrigerant recharge)
- Repair cost is less than 50% of a new system's price
- Your energy bills have been stable
Consider Replacing When…
- The unit is 12+ years old
- You've had multiple repairs in the past 2 seasons
- Your energy bills have been steadily climbing
- The repair cost exceeds 50% of a new system's price
- The system uses R-22 refrigerant (now discontinued)
The $5,000 Rule
Multiply the repair cost by your system's age in years. If the result exceeds $5,000, replacement is generally the smarter long-term investment. For example, a $400 repair on a 15-year-old unit ($400 × 15 = $6,000) suggests it's time to consider a new system. At Comfort Union, we'll give you an honest assessment — we never push a replacement if a repair is the right answer for your home.

What Calgary Homeowners Are Saying
I was referred to Comfort Union by a friend who had recently installed an air conditioning unit, and I’m so glad I took their recommendation. From the moment they quoted the job in person to the completion of the installation the following week, Comfort Union provided excellent service. The pricing they offered was competitive, and their team was easy to deal with throughout the process. I appreciate their hard work. Highly recommended for all you HVAC needs!
Comfort Union is a hidden gem. The team is very caring about their customers. I had them install an A/C unit for me over the summer and it was quick, affordable and reliable. The team cleaned up after themselves and kept my property clean. I will use them for all of my HVAC needs.

AC Repair Calgary — Frequently Asked Questions
How much does AC repair cost in Calgary?
Most air conditioner repairs in Calgary range from $150–$1,200 depending on the part, labour, and system age. A service call and diagnostic typically runs $100–$150. Comfort Union provides a full upfront quote before any work begins so you know the exact cost before we start. See our pricing table above for common repair cost ranges.
How quickly can you repair my AC in Calgary?
In most cases, same day. We offer 24/7 emergency air conditioner repair across Calgary and aim to respond within 1–2 hours for urgent calls. Non-emergency repairs are typically booked within 24 hours. Call 403-399-7903 any time — day or night.
What is the $5,000 rule for AC repair?
The $5,000 rule is a guideline used by HVAC professionals: multiply the cost of the repair by the age of your system in years. If the result exceeds $5,000, replacement is usually the more cost-effective long-term decision. For example, a $400 repair on a 15-year-old unit ($400 × 15 = $6,000) would suggest considering a new system. Comfort Union will always give you an honest recommendation either way.
Is it cheaper to repair or replace my air conditioner?
It depends on the system age and repair cost. If your AC is under 10 years old and the repair is under $500, repair is almost always the right choice. If the unit is over 12–15 years old and facing a major repair like a compressor replacement, a new air conditioner installation in Calgary may be more economical over the long run. Our technicians will give you an honest, no-pressure assessment.
What are the most common AC problems in Calgary?
The most common air conditioner issues we see in Calgary homes are: low refrigerant due to a leak, failed capacitors or contactors, dirty or frozen evaporator coils, clogged condensate drains, and faulty fan motors. Most of these are relatively straightforward repairs when caught early — which is why annual AC tune-ups are so valuable.
What is the 3-minute rule for air conditioners?
The 3-minute rule says you should wait at least 3 minutes after turning off your AC before restarting it. This allows the refrigerant pressure to equalize and prevents the compressor from short-cycling, which can cause expensive damage. If your AC is shutting off and restarting frequently on its own (short-cycling), that’s a problem that needs professional attention — call us for a diagnosis.
Why is my AC running but not cooling my Calgary home?
The most common causes are a clogged air filter restricting airflow, low refrigerant from a leak, frozen evaporator coils, or a failing compressor. Start by checking and replacing your filter — it’s free and fixes the problem more often than you’d think. If the problem persists after a filter change, call Comfort Union. Our technicians can diagnose and often repair the root cause the same day.
Do you offer emergency AC repair in Calgary?
Yes. Comfort Union provides 24/7 emergency air conditioner repair across all of Calgary — NW, NE, SW, and SE. We respond to emergency calls around the clock, including weekends and holidays. When your AC fails on the hottest day of the year, we’re the team to call. Reach us any time at 403-399-7903.
Do you repair Carrier air conditioners in Calgary?
Yes — and as an authorized Carrier dealer, we have specialized factory training on the full Carrier lineup. Whether it’s a Carrier Infinity, Performance, or Comfort Series system, our technicians are certified to diagnose and repair it correctly. Carrier AC repair in Calgary is one of our specialties, and we carry commonly needed Carrier parts on our service trucks.
How often should I service my air conditioner in Calgary?
We recommend an annual AC tune-up in spring, before Calgary’s cooling season begins. Regular maintenance catches small issues before they become expensive repairs, extends the life of your system, and keeps your unit running at peak efficiency through our hot Calgary summers. A well-maintained AC also consumes 15–25% less energy than a neglected one.
