A read, not a look
Gauges on the service ports, an amp draw on the compressor and the fan, and a temperature split measured across the coil. Those three readings name the fault.

Common air conditioner symptoms
The air conditioner faults we get called out for most
Six faults account for most of the AC repair Calgary homeowners actually need. The symptom points at the cause, and the cause is what sets the bill.
Cool setting on, warm air out
Often a low charge from a leak, or a stalled compressor
The most common call of the season. We check the charge, the capacitor, the contactor, and whether the thermostat is really sending the call outside.
A hum outside, and then nothing
Usually a failed run capacitor, or a pitted contactor
The compressor and the outdoor fan both need a capacitor to break away from a standstill. It is one of the least expensive things on this list.
Ice on the copper line at the furnace
Usually airflow starvation, or a low refrigerant charge
A blocked filter, a shut return, a dying blower, or a leak. Switch the cooling off and leave the fan running to thaw it before anyone comes out.
The breaker trips every time it starts
A seizing compressor, a short to ground, or a tired breaker
The breaker is doing its job. Resetting one repeatedly on a hard electrical fault is how a repair becomes an electrical job, so leave the system off.
Starts, then stops a few minutes later
Short cycling, from a dirty condenser or an oversized system
It never runs long enough to cool the house or pull the humidity out, and every restart is the hardest work a compressor ever does.
Water on the floor beside the furnace
Usually a blocked condensate drain, or a plugged trap
The evaporator coil pulls litres of water out of the air on a humid day and all of it has to go somewhere. A blocked drain floods quietly.
There is a reason the same six turn up here. Cottonwood seed and construction dust blind a condenser coil, hail flattens its fins, and a short season hides a slow leak. It is why AC repair in Calgary clusters into a few weeks.

Repair or replace
Repair the air conditioner, or replace it?
Age alone does not decide this. What failed matters more. If the answer is to replace it, read AC Installation & Replacement.
Repair it
The system has good years left and the part that failed is not an expensive one.
- Under about ten years old and it has cooled reliably until now
- A capacitor, contactor, condenser fan motor, or a control board
- A refrigerant leak somewhere accessible rather than buried in the coil
- It runs on R-410A, subject to parts and refrigerant availability
- The repair costs a small fraction of a replacement and buys several summers
Replace it
The repair keeps coming back and the money is going into equipment that owes you nothing.
- Twelve to fifteen years old, a normal working life for cooling here
- A failed compressor, which means the sealed system opened up
- A leak inside the evaporator coil, where reaching it means pulling it
- It runs on R-22, out of production and import in Canada since 2020
- The second or third repair in as many summers, and the furnace is going too
If a repair gets you another few good summers we will do the repair and say so plainly. Nobody here is paid to sell you an air conditioner you do not need.
In every AC service call
What's included in an AC repair Calgary call
Two repair bills for the same fault can sit a long way apart, and it is rarely the part that explains it. These four things are in every call we take.
The number before the work
Nothing is fitted on a verbal. The repair is written down and agreed first, and the figure you agree to is the figure on the invoice when we leave.
The usual parts on the van
Capacitors, contactors, condenser fan motors and control boards travel with us, so the faults we are called out for most are one visit rather than a wait.
Cleaned up, and covered
Boot covers on the way in, the old parts away on our truck, and nothing left in the mechanical room for you to deal with. Two year warranty on the labour.
Those four are in every air conditioner repair we take on in Calgary, and they are on the invoice by name.
The visit
AC repair Calgary, step by step
Three steps, and no part goes in until you have agreed the price of it. That is how every repair we do runs.
Both ends of the system
A cooling fault sits in one system split across two places, so the visit starts at the condenser outside and finishes at the coil and blower indoors.
The price before the part
You are told what failed, what the repair costs, and how much life the rest of the system has. If the money belongs in a replacement, you get both numbers.
Fixed, then measured
Repair done and the temperature split across the coil measured in front of you. Boot covers on, old parts away with us. Two year warranty on the labour.
The quote is written on the visit, not posted to you three days later. If your system is down right now, skip the form and call. 24/7 emergency service, an owner answers or calls back.
AC repair timeline
AC repair Calgary: how long does it take?
Most AC repair in Calgary is finished in one visit. A capacitor, a contactor, or a condenser fan motor is an afternoon and a part off the van.
One visit, most of the time
The electrical faults and the parts we carry. Diagnosed, agreed and fitted inside the same call, which is how most of the repairs we take on finish.
A sealed system takes longer
Recovering the refrigerant, repairing the leak, pulling a vacuum and weighing a fresh charge back in is a day of work rather than an hour, and it cannot be rushed.
Waiting on a part
Anything not on the van is a courier rather than an afternoon. On obsolete equipment that is what turns one visit into two, and you hear it on the phone.
None of that is a promise about when somebody can be at the door. Ring the number, describe what it is doing, and you get the honest version of both.
Why TNT
Why Calgary homeowners choose TNT
Five things worth checking before anybody opens a sealed refrigerant system. They separate one AC repair Calgary quote from the next.
Diagnose, then quote
Not parts fitted on a hunch
Pressures read, capacitor and contactor tested, amp draw checked, airflow confirmed. Fitting the usual suspect and hoping is how somebody pays twice for one fault.
Repairs that hold
We will say when not to spend
If a capacitor buys you another five summers, that is the job and we will say so. If a compressor on an old system is wasting money, you hear that instead.
Answered, not queued
24/7, answers or calls back
No receptionist and no answering service. Ring at any hour and an owner answers or calls straight back, tells you what to switch off, and is straight about when somebody can be there.
In-house crew
No subcontractors, on any job
The technician standing at your condenser is a TNT employee, not somebody hired for the week of a heat wave. The fifth call of the day gets the same standard.
Priced in writing
Two year warranty on the labour
The fault, the part and the price, all agreed before anything goes in. If our workmanship is what failed we come back and put it right, no argument.

TNT Heating & Air Conditioning
5.0Rated on Google
Five stars from every customer who has left a review, on replacements, on after-hours calls, and on the repairs homeowners book.
Not only was TNT very reasonably priced, they fit me into their busy schedule during the heat spell and got me all set up in no time.
John Klassen
Jaime was professional and kept me informed throughout the entire process… His technician arrived on time, was knowledgeable, and took the time to answer all of my questions.
Glenn Jefferies
It was -30 kind of winter day… other companies asked for us to wait over 24 hours… Jamie came to service our non heating furnace within an hour and fixed the problem quickly.
Adelia Timirboulatova
TNT installed the furnace system on our new build, and then we proceeded to get our AC with TNT as well. Jamie was super responsive, kind, and informative… In addition to being fairly priced.
Christina Golubic
Amazing service. I would not go with anyone else. Jamie tells you the truth, stands by his work and follows up.
Robert Milne
Jamie and his team provide incredible expertise. They gave me consultative choices to improve my existing system, and clean installation done right… all at a fair price.
Trevor
Great job and great price.
Murray Jonasson
Would highly recommend. Check with TNT before making any decision regarding heating or AC install. Believe me. They were amazing.

What it costs
What moves the price of an air conditioner repair
Nobody honest prices a repair down a phone line. Six things decide what an AC repair Calgary homeowners book costs, once somebody has actually read the system.
Which part actually failed
The gap between the cheapest and the dearest fault on an air conditioner is wide. A control component is one job. A compressor is the sealed system opened up.
The refrigerant it runs on
What it runs on decides the bill. R-22 has been out of production in Canada since 2020, and R-410A is the older standard now, so parts and refrigerant for both depend on availability.
Where the leak turns out to be
A flare, a service valve or an accessible run of line set has a clear end to it. A leak inside the evaporator coil above the furnace means pulling the coil.
The condition of the rest of it
A condenser coil packed with cottonwood, a blower wheel loaded with dust, or hail-flattened fins all change what the repair has to include to hold.
How long it ran faulty
One part, caught early. The same fault left running takes something else with it, because an iced coil floods liquid back to a compressor that cannot survive it.
Whether the part is still made
An obsolete outdoor unit takes a sourced part rather than one off the van, and a discontinued board or compressor prices differently from a current one.
An AC service call in Calgary should be priced on what is found, not guessed at over the phone. We read the system, say what failed, and put the price in writing before a part goes in.

AC repair Calgary FAQs
AC repair Calgary questions
The ten questions we get asked most about the repair itself. If yours is not here, ring the number and ask an owner.
- It depends on which part failed, and you get the number in writing before anything is fitted. A capacitor, a contactor, or a condenser fan motor sit at the affordable end of the range. A compressor, or a refrigerant leak buried in the evaporator coil, sit at the other end of it. The diagnosis is what settles the question, so we read pressures and amp draw first and price the repair second. If the money belongs in a replacement instead, you get both numbers.
- Usually a low refrigerant charge caused by a leak, a failed capacitor, an iced up coil starved of airflow, or a call for cooling the outdoor unit never receives. Those four faults look identical from inside the house and cost very different amounts to put right, which is why we diagnose before quoting a part. If the copper line at the furnace has frost on it, switch the cooling off now and leave the fan running. Running an iced up system is how a compressor gets destroyed.
- Call the number and an owner answers or calls straight back, and you get told honestly when somebody can be there. Cooling season here is short and intense, so a heat wave books the whole city out inside the same week. What we will not do is take the booking and leave you guessing at the window. If we cannot reach you quickly you hear that on the phone, along with what to do in the meantime to keep the house liveable.
- Yes. The line is open around the clock and it rings an owner rather than a receptionist or an answering service. Not every cooling fault is a middle of the night emergency, and we will tell you plainly when something can safely wait until morning. A house with an infant, an elderly parent, or somebody with a respiratory condition in it during a heat warning is not treated as a routine call. You get a person on the phone either way.
- Ice on the copper suction line means airflow or refrigerant, and either way the system needs switching off now. A clogged filter, a closed off return, a blocked evaporator coil, or a failing blower starves that coil of warm air and it drops below freezing. A low charge from a leak does exactly the same thing. Switch the cooling off, leave the fan running to thaw the coil, and change the filter. If it ices up again, it has a fault.
- Starting and stopping every few minutes is called short cycling, and it usually means a restriction, a control fault, or a system too large for the house. A condenser coil choked with dust, a low refrigerant charge, a failing capacitor, or a thermostat sitting in afternoon sun will all cause it. So will an air conditioner oversized when it was installed, which satisfies the thermostat before it has run long enough to pull humidity out. Short cycling wears a compressor out early.
- Stop resetting it and call us, because a breaker that trips repeatedly is doing its job and telling you something is drawing current it should not. The usual causes are a seizing compressor, a shorted capacitor, a contactor welded shut, or a condenser coil so choked with cottonwood and dust that the unit is running at high head pressure. Resetting a breaker over and over on a fault you cannot see is how a small repair becomes an electrical one.
- No, because refrigerant is not a consumable, so a system that is low has leaked and the leak is the actual repair. Adding gas to a leaking system cools the house for a few weeks, vents refrigerant into the atmosphere, and puts you back where you started with less money in your pocket. We find the leak, tell you where it is and what it costs to put right, and only then talk about charging the system back up.
- Sometimes, and it comes down to which part failed rather than the birthday on the data plate. Twelve to fifteen years is a normal working life for cooling equipment in Calgary, and a system that age needing a contactor or a fan motor is worth fixing without hesitation. The same system needing a compressor or a leaking coil, on a refrigerant that is being phased out, is money going into equipment that owes you nothing. You get both numbers.
- Every repair carries a two year warranty on the labour, so if our workmanship is what failed we come back and put it right. Parts carry whatever the manufacturer gives them, and you are told which is which in writing before anything goes in. We repair whatever brand is sitting beside the house and whoever put it there, because most of the home air conditioning we work on in Calgary was installed by somebody else years ago.
