We specialize in car AC repair. With the right diagnostic approach, we can identify whether your cooling problem is caused by a leak, compressor issue, electrical fault, condenser restriction, damaged AC line, or another HVAC system failure.

At Radman Auto Repair, we understand that air conditioning repair requires real experience. Guessing and "just recharging it" can waste money if the system has an active leak or underlying fault. We help Concord drivers get the correct repair the first time.

Section 01

Common Car AC Problems We Diagnose

A weak AC system does not always mean it only needs refrigerant. Modern automotive HVAC systems rely on pressure control, airflow, electrical signals, sensors, compressor operation, and leak-free lines.

Warm Air From Vents

Often caused by low refrigerant, leaks, compressor trouble, pressure switch faults, or blend door issues.

AC Leak or Low Refrigerant

We look for the source instead of simply refilling a leaking system.

Rusted A/C Lines

Ontario salt can corrode AC lines, fittings, condensers, and related components.

Electrical AC Faults

Relays, fuses, sensors, wiring, fan control, and module communication can all affect AC operation.

Frequently Asked Questions

Can I just recharge my AC?
Sometimes a recharge is part of the repair, but if the system is low, there may be a leak. We diagnose the cause before recommending a refill.
Why does my AC blow cold sometimes and warm other times?
Intermittent AC can be caused by compressor cycling problems, electrical faults, pressure issues, sensor problems, or cooling fan operation.
Do you repair rusted A/C lines?
Yes. Rusted A/C line repair is one of the common HVAC issues we see because Ontario road salt is hard on exposed metal lines and fittings.

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!
