The quick checklist
When your AC quits on a 32 °C July afternoon, it is tempting to call the first number you find. Spending five minutes on the questions below protects you from bad repairs, surprise bills and voided warranties. Here is the short version.
Licensing
The technician holds an Ontario refrigeration licence and an ozone depletion prevention (ODP) card. If the job touches your furnace or gas line, they also need TSSA gas certification.
Company credentials
TSSA-registered contractor, HRAI membership, liability insurance and WSIB coverage.
Reviews
A large number of recent Google reviews that mention AC work, not just a few old five-star ratings.
Pricing
The diagnostic or service-call fee is stated up front, and you get a price before the repair starts.
Response
A clear answer on when they can come, including evenings and weekends in a heat wave.
Warranty
A written answer on how long parts and labour are covered.
Honesty
They explain the problem in plain language and give you a repair option before talking replacement.
The rest of this guide explains each point, what fair AC repair prices look like in Ottawa in 2026, and the red flags that should make you hang up.
1. Licences: the non-negotiable part
Central air conditioners and heat pumps run on refrigerant under high pressure. In Ontario, anyone who handles refrigerant needs proper refrigeration training and an ozone depletion prevention (ODP) card, and residential AC work is normally done by a technician holding a refrigeration and air conditioning licence. Ask for both. A legitimate tech will not be offended.
Most Ottawa homes pair the AC with a gas furnace. The indoor coil sits on top of the furnace and the furnace blower moves the cool air. If the repair involves the furnace, its control board or any gas component, the technician must hold a TSSA gas technician certificate and work for a TSSA-registered contractor. The Technical Standards and Safety Authority regulates fuel-burning appliances in Ontario.
Also worth checking:
HRAI membership
(Heating, Refrigeration and Air Conditioning Institute of Canada) signals the company follows an industry code of ethics.
Liability insurance and WSIB coverage
Protect you if someone is hurt or something is damaged at your home.
Gatineau homes
Need a contractor licensed to work in Quebec. Not every Ottawa company is.
Oria Heating and Cooling is TSSA and HRAI approved, every technician holds AC (refrigeration) and gas licences, and the company holds the licences required to work in Gatineau.
2. Reviews: read them, don’t just count stars
A 4.9-star rating from 12 reviews tells you very little. Look for a company with hundreds of reviews collected over several years, then read the recent ones.
Search the reviews for “AC” or “air conditioner”.
A company can be great at furnaces and weak on cooling.
Look for names.
Reviews that mention the same technician again and again usually mean real, repeat customers.
Read the one- and two-star reviews.
How the owner responds tells you how they handle problems.
Watch for patterns
“showed up when they said”, “explained everything” and “price matched the quote” are the comments that matter.
For reference, Oria holds a 5.0-star Google rating from 578 reviews, and many of them name lead technician Mansoor. One customer, Kenneth D., wrote: “I’ve called them once for my AC and once for my furnace and both times had excellent service. They are quick to respond and very knowledgeable, offering creative and reasonable solutions.” You can read more on our customer reviews page.
3. Pricing transparency and typical AC repair costs in Ottawa
A good company tells you what the visit costs before they arrive and gives you a firm price before any repair begins. You should never find out the cost from the invoice.
Here are typical Ottawa ranges for 2026 so you can tell whether a quote is in the right neighbourhood. Most common AC repairs fall between $150 and $1,200; a compressor replacement runs $1,800 to $3,500.
| Repair | Typical Ottawa cost (2026) |
|---|---|
| Diagnostic visit plus a simple fix (breaker, float switch, thermostat setting) | $150 – $250 |
| Capacitor replacement | $150 – $400 |
| Contactor replacement | $150 – $400 |
| Clogged condensate drain or failed condensate pump | $150 – $450 |
| Condenser fan motor | $450 – $900 |
| Refrigerant leak search, repair and recharge | $400 – $1,200 |
| Compressor replacement | $1,800 – $3,500 |
| AC tune-up (preventive) | $120 – $200 |
| Full central AC replacement | $4,000 – $8,000 |
The final price depends on your home, the equipment and the work involved, and Oria gives free quotes on any equipment purchase. For a deeper breakdown, see our guide to AC repair cost in Ottawa.
Questions to ask on the phone: What is your service-call fee? Does it apply toward the repair? Do you charge extra for evenings or weekends? Will you give me the price before you start?
4. Response time and availability
Ottawa heat waves hit everyone at once. During a stretch of 30 °C days with a humidex near 40, good companies get busy fast, so ask directly when they can come and whether they offer emergency service.
- Ask whether they answer the phone after hours or just take a message.
- Ask if a technician can troubleshoot over the phone first. Many “no cooling” calls turn out to be a tripped breaker, a dead thermostat battery or a blocked filter.
- Ask whether the technician carries common parts (capacitors, contactors, fan motors) on the truck. That is often the difference between a same-day fix and a second visit.
Oria offers 24/7 emergency service and same-day repair is often available. Phil G. described his visit this way: “Mansoor was incredibly fast to respond, offered help over the phone and came over the following morning. He’s a total pro, diagnosed the problem within a few minutes…” Learn more about our emergency HVAC service.
5. Warranty questions to ask before you agree
Warranty terms vary a lot between companies and manufacturers, so ask and get the answer in writing on the invoice.
- 1
How long is the labour on this repair guaranteed?
If the same problem comes back next month, will they charge you again?
- 2
Is the replacement part covered by the manufacturer?
Many AC parts carry a manufacturer parts warranty, but labour is usually separate.
- 3
Is my unit still under the original warranty?
Many systems installed in the last 10 years still have parts coverage if they were registered. A good technician will check the serial number.
- 4
Will this repair affect my existing warranty?
Non-approved parts or unlicensed work can void manufacturer coverage.
Red flags: when to get a second opinion
Any one of these is a reason to pause before paying.
Replacement before diagnosis
If someone says you need a new system before they have put gauges on it and tested the electrical parts, get another opinion.
Topping up refrigerant every year
AC systems are sealed. Needing refrigerant means there is a leak. Recharging without finding it just wastes money.
No licence on request
A technician who can’t show a refrigeration licence, ODP card or TSSA certificate should not be working on your system.
Cash-only, no paperwork
No written quote or invoice means no warranty and no proof the work was done properly.
Pressure tactics
“This price is only good today” is a sales tactic, not a diagnosis. A fair quote is still fair tomorrow.
Vague answers
If they can’t explain in plain words what failed and why, you can’t judge whether the repair makes sense.
Common AC problems in Ottawa homes
Knowing the usual suspects helps you describe the problem on the phone and judge the diagnosis.
Outdoor unit humming but fan not spinning
Usually a failed capacitor or fan motor. Turn the AC off to protect the compressor.
Indoor unit runs, outdoor unit silent
Tripped breaker, failed contactor, or a thermostat or low-voltage wiring fault.
Ice on the copper lines or indoor coil
Low airflow (dirty filter, closed vents) or low refrigerant from a leak. Switch to “fan only” to thaw and call for service.
Water around the furnace
A clogged condensate drain or failed condensate pump. Common in humid Ottawa summers.
Short cycling or weak cooling upstairs
Can be sizing, ductwork, a failing component or simply a dirty outdoor coil packed with cottonwood fluff.
R-22 systems
Units from before about 2010 may use R-22, which has been phased out. Leaks on these are expensive to recharge and often point toward replacement.
Before you call, check the thermostat, the breaker and the filter. Our article on what to do if your AC is not working walks through these checks step by step.
Repair or replace: what a good company will tell you
An honest contractor gives you the numbers and lets you decide. A useful rule of thumb: if the system is over 12 to 15 years old, uses R-22, or the repair is more than about half the cost of a new unit, replacement is worth pricing. A compressor failure on a 14-year-old unit is the classic example.
If the system is younger and the fault is a capacitor, contactor, drain or fan motor, repair is almost always the better value. For more on making that call, read should I repair or replace my AC.

Frequently Asked Questions
What licence does an AC technician need in Ontario?
An AC technician in Ontario should hold a refrigeration and air conditioning licence and an ozone depletion prevention (ODP) card, which covers safe refrigerant handling. If the work touches your furnace, gas valve or gas line, they also need a TSSA gas technician certificate and should work for a TSSA-registered contractor. Ask to see these before work starts.
How much does AC repair cost in Ottawa?
Most common AC repairs in Ottawa cost between $150 and $1,200 in 2026. Small parts such as capacitors and contactors sit at the low end, while refrigerant leak repairs and fan motors sit higher. A compressor replacement is the big one at $1,800 to $3,500. Final cost depends on your equipment and the fault found.
How quickly should an AC repair company respond?
In a heat wave, a good Ottawa company should give you a clear arrival window when you call, often the same day or next morning. Ask whether they offer 24/7 emergency service and whether they carry common parts on the truck. Many companies, including Oria, can also troubleshoot simple issues over the phone first.
Is it a red flag if a technician says I need refrigerant every year?
Yes. Central air conditioners are sealed systems, so they should never need regular top-ups. If refrigerant is low, there is a leak somewhere. A trustworthy technician will find and repair the leak, or explain why repair isn’t practical, instead of recharging the system year after year and billing you each time.
Should I get more than one quote for AC repair?
For small repairs under a few hundred dollars, one reputable company is usually enough. For a compressor, coil replacement or any recommendation to replace the whole system, a second opinion is reasonable. Compare the diagnosis, not just the price, and make sure each quote covers the same parts, labour and warranty.
What warranty should I expect on an AC repair?
Ask two separate questions: how long the company guarantees its labour on the repair, and whether the part carries a manufacturer warranty. Terms differ between companies, so get the answer written on your invoice. Also ask whether your original system warranty is still active, since registered units often keep parts coverage for years.
Can the same company fix my AC and my furnace?
Yes, as long as the technician holds both a refrigeration licence and a TSSA gas certificate. In most Ottawa homes, the AC coil sits on the furnace and uses the furnace blower, so many cooling problems involve both. Oria’s technicians hold AC and gas licences, so one visit can diagnose the whole system.
