“A couple of days ago We took the Mazda 2010 in for the first time at Marks Auto.
Had to get the sway bar links, relay, one ball joint replaced, cabin filter, and A/C refrigerant topped up. Needed other repairs, but will bring in at a later date.

Mark is upfront and honest, he takes the time to explain everything thoroughly. He reminds me of a teacher for Automotive Care, Repair. He talked for probably an hours worth for free over the phone in total explaining cars, parts, automotive with my partner. I had my partner talk to him since initially I was nervous since in my past Automotive places in town took advantage that I am female.

As experiences at other shops in town I / we had were bad... it helped that Mark was willing to take the time to explain thoroughly without rushing and hurrying you off the phone, or in person. He is like a Tibetan Monk so calm, puts you at ease, and reassuring.

You can tell he & team are very passionate and dedicated to their work. They all have a very calm and professional demeanor.
Him and his team also are helpful, personable, and caring about their work.

They are prompt and efficient, updating you along the way, and you will have your car returned and fixed fast.
The team offered a loaner car as well which helped! Since I lived 22 minutes drive away.

I found him easy to talk to.. I didn't tell him but I have a ( high functioning) Autism Spectrum Disorder diagnosis. I did tell him I have ADHD though, and he was very cool and non-judgmental.

Yes, I understand prices are a complaint in the comments but I felt you pay for quality work so it was worth the ease of knowing you are in good hands.

I will return again !
Thank you all at Marks Auto.”

“My 1st experience with Mark and his crew was needing a/c service for my 2008 HHR. He took my car in right away for diagnostic. Repaired in a couple of days and provided a loaner car to boot. My 1976 Corvette required drive train service. Mark is extremely knowledgeable on Corvettes. The work was completed beyond my satisfaction. If you are in need of an exceptional auto service garage, here it is!”

“Hey Mark,

Ted here, fantastic service!

Was a little skeptical at first, but I was recommended by a friend named Aiden from parts source. I am someone whom is hard to trust, but considering that they a) lemme use my own parts b) let me watch the car while its being serviced and c) were very informative on what they were doing, and even educated me and well I was able to even talk car talk on the side with the mechanics.

I think a guy named barry worked on my car. Fanominal job! (Pardon my spelling) they were honest, and were all around very friendly and particular (in a good way).

I think the only thing I would say, is that it was a little expensive, so their services are a little out of my budget as a student, but minus that the service was great!

Thank you for your service, would recommend to a friend!”

Common Causes of AC & Heating Failure

Refrigerant leaks from deteriorated O-rings, hoses, or the condenser
Failed compressor clutch or internally damaged AC compressor
Clogged cabin air filter restricting airflow to the vents
Leaking or plugged heater core causing foggy windows and sweet smell
Broken blend door actuator preventing hot/cold air mixing
Failed blower motor or resistor stopping airflow from the vents entirely

Signs Your Auto AC or Heating System Needs Service

Air conditioning blows warm air instead of cold
Heater blows cold air even after the engine warms up
Weak airflow from the vents even at the highest fan setting
Strange sweet smell inside the cabin indicating a heater core leak
Unusual clicking or grinding noises when adjusting the temperature
Windows fog up excessively and the defroster doesn't clear them

Auto AC & Heating Tips

Run your AC system for at least 10 minutes per month even in winter to keep the seals lubricated
Replace your cabin air filter every 20,000-25,000 km for optimal airflow and air quality
If your AC stops blowing cold, get a leak test before just adding more refrigerant
A sweet antifreeze smell inside the cabin is a strong indicator of a leaking heater core
After winter, have your AC system inspected before the summer heat arrives
Don't ignore a defroster that doesn't work—it's a serious safety hazard in cold weather

Frequently Asked Questions

How much does an AC recharge cost in Kitchener? +
A basic AC recharge with leak inspection costs $150-$300. If a leak is found and a component needs replacement (condenser, evaporator, or compressor), the total repair can range from $500-$2,000+.
Why does my AC blow cold then warm? +
This is often caused by an intermittent refrigerant leak, a failing compressor clutch, or a blocked expansion valve. A professional leak test and system pressure check can pinpoint the exact cause.
How much does heater core replacement cost? +
Heater core replacement is labor-intensive because the dashboard must be partially or fully removed. Expect to pay $800-$1,800+ depending on your vehicle's complexity.
How often should I recharge my car's AC? +
A properly sealed AC system should not need regular recharging. If it needs refrigerant frequently, there's an active leak that must be repaired first to avoid environmental damage and ongoing costs.
