When your A/C is weak, intermittent, blowing warm air, or not working at all, Radman Auto Repair provides car AC repair with a $135 pressure and leak test with a full A/C system evaluation. We diagnose gas, hybrid, electric vehicle, and Tesla climate systems properly before recommending repairs.
Your A/C Does Not Have to Be Totally Dead to Need Testing
The most common reason to call us is simple: your car A/C is not working the way it should. It may still blow cool sometimes, work only on certain days, take too long to cool the cabin, or stop performing when the weather gets hotter.
The Problem
Weak cooling, intermittent cooling, warm air, pressure loss, refrigerant leaks, clogged components, compressor issues, or rusted A/C lines can all feel like the same problem from the driver's seat.
The Radman Solution
We test the system first, identify the actual cause, and recommend the repair that fits: recharge, leak repair, rusted line repair, TXV diagnosis, compressor diagnosis, condenser repair, or full component replacement when required.
$135 Pressure & Leak Test and Full A/C System Evaluation
We start with a $135 pressure and leak test with a full A/C system evaluation. Our technicians spend up to 2 hours diagnosing and testing the system. Depending on the vehicle and symptoms, this may include pressure testing, leak detection, component checks, refrigerant type confirmation, performance testing, and inspection for corrosion or failed A/C components.
You do not need to wait until your A/C completely stops. If it is not cold enough, not consistent, or not working all the time, book the test before a smaller issue becomes a bigger one.
Car AC Blowing Warm Air, Weak Cooling, or Not Cold?
Warm Air From Vents — May indicate low refrigerant, a leak, compressor issue, blend door fault, condenser problem, or restricted flow.
Weak Cooling — Often needs pressure testing, temperature checks, airflow inspection, and condenser/compressor evaluation.
A/C Works Sometimes — Can involve sensors, compressor controls, refrigerant charge, fan operation, or electrical faults.
Recharge Did Not Last — Usually means the leak or root cause was not repaired. Testing comes before another top-up.
Replacing AC Lines — Etobicoke's Cost Saving Pro
Ontario road salt and harsh GTA winters are brutal on A/C lines. Most dealerships will tell you the entire line must be replaced, which can cost thousands in parts and labour. When appropriate, Radman can repair only the defective or rusted section.
Radman Expert Tip: We have the tools to replace only the defective section of the A/C line when suitable. This precision repair restores system integrity while helping save hundreds of dollars.
1234yf & 134a Leak Testing — Why We Use Nitrogen
Finding a pinhole leak in a modern A/C system requires more than a quick visual check. At our Rexdale shop, we use dry nitrogen gas for pressure testing instead of compressed air. Compressed air can introduce moisture into the system, which can contribute to corrosion and internal damage.
No moisture — Dry nitrogen avoids adding moisture to sensitive A/C components.
Better pressure testing — Nitrogen allows safe testing to identify leaks that may only appear under operating conditions.
Cleaner diagnosis — Helps decide whether you need a recharge, line repair, TXV diagnosis, or deeper component repair.
We Fix Gas, Hybrid, Electric & Tesla A/C Systems
Modern climate control systems are more complex than old-school A/C. Gas vehicles, hybrids, and electric vehicles can use different compressors, pressure strategies, refrigerants, and control logic. Radman handles all three categories, including Tesla climate system diagnosis.
AC Symptoms & Parts
AC Compressor
The heart of the system. If your A/C blows warm air, cools inconsistently, or makes a loud squealing noise, the compressor or clutch may be failing. See catastrophic AC compressor failure.
Condenser
Located at the front of the vehicle, exposed to road debris, salt, and corrosion from 401 and 427 driving.
AC Evaporator
Deep within the dashboard. A musty smell or refrigerant leak may mean the evaporator needs complex, labour-intensive replacement.
Receiver-Drier
Removes moisture from refrigerant. Often replaced when the A/C system is opened to help prevent future damage.
Etobicoke A/C Repair for GTA Driving Conditions
A/C problems in the GTA are often tied to the way vehicles are used here: winter salt, freeze-thaw cycles, humid summer traffic, stop-and-go driving, and road debris from routes like Highway 401, 427, 407, and local Rexdale roads. Radman Auto Repair is located at 321 Rexdale Blvd #4 in Etobicoke, serving drivers from Toronto, Mississauga, Brampton, Vaughan, Woodbridge, Rexdale, and surrounding GTA communities.

Can Radman repair only the rusted section of an A/C line?
When suitable, Radman can repair only the defective or rusted section of an A/C line instead of replacing the entire line, saving money while restoring proper system operation.

Yes. Radman Auto Repair diagnoses and repairs air conditioning systems on gas, hybrid, and electric vehicles, including Tesla climate-control diagnosis.
Alex is a great guy. He took the time to respond by phone and walk me through my options for my Tesla Model Y 2024 and gave me his perspectives as a Tesla owner. Top recommendation in my books for the Toronto area.
I cannot say enough good things about Livio and the team at Radman Auto Repair in Rexdale. We brought in my son’s 2015 Mitsubishi Lancer because the A/C was malfunctioning. We had already been to two other shops, paid for diagnostics, and received different explanations, so we were frustrated and unsure what to do next.
Livio was outstanding. He listened carefully, looked at the issue, and explained everything clearly and in detail in a way that actually made sense. He was able to narrow down what was going on within minutes, without guessing, pressure, or recommending unnecessary work. What really stood out was that he did not charge us another diagnostic fee after learning we had already paid for two separate diagnoses.
Even better, the work was completed the same day, which was a huge relief. It is rare to find a mechanic who is knowledgeable, honest, patient, efficient, and genuinely focused on helping customers understand the real issue before they spend money on repairs.
Livio truly gets it. We are so happy we found Radman Auto Repair and would highly recommend Livio and his team to anyone looking for trustworthy, skilled, and customer-focused service..
My 2015 Honda CR-V was blowing hot air and making noise when the A/C was on. The Compressor and Expansion valve needed replacement due to metal debris in the system.
I rarely write reviews, but I felt it would be wrong not to appreciate Radman for their service, especially after what I went through before finding them.
I’m writing this one month after the repair because I wanted to test my A/C on multiple long trips before recommending them.
One thing I learned from this experience is that many mechanics know how to replace parts, but very *few follow the right procedures* and perform the proper checks. I initially went for a cheaper repair at a local mechanic. The problem came back, and afterward he didn’t seem to know what to do next.
I found Radman through Google reviews without any personal recommendation, so I was taking a chance. They properly diagnosed the issue, explained everything clearly before starting the work, didn’t exaggerate the problem, and charged me a reasonable price. A/C issues can be complicated but they answered all my questions and I honestly haven’t had such a good and detailed conversation with a mechanic in the GTA about an A/C problem. Their knowledge and experience with A/C systems really stood out.
I also had a catalytic converter issue. Another mechanic simply recommended replacing it, which would have cost at least $2,000. Radman explained that considering the age and condition of my 2015 CR-V, such an expensive replacement might not make sense. They gave me the replacement cost but also suggested trying Cataclean first. I tried it, and so far I haven’t had any issues.
After a month and several long trips, my A/C is still working well. It’s rare to find this combination of knowledge, transparency, and honesty.
Thank you, Radman, for the knowledgeable and honest service. I genuinely appreciate it.
I fix my cars myself but I always go to Radman for AC work. Been coming here for years and they do great work and are fairly priced. The guys are honest and reliable. Very clean waiting room too!
Finding a mechanic who actually understands EVs and is completely trustworthy is hard to come by, but Radman Repair is excellent. The service was top-notch, they explained everything to me with so much patience, and the overall experience was a 10/10. 100% recommended!
