“I rented a car from Enterprise in Brampton and was driving to the US when 45 mins into my trip I got a notification about low air. Knowing I had a long drive I was trying to find a place I could have the tire checked. Like out of a heaven… I saw Beverly Auto and Tire Centre. I drive over and asked the desk associate if someone could help me as I didn’t know what to do or how bad it was. I was starting to worry and he eased my worry by saying to go to Bay Door 2 and he will get someone to help me. When I got there someone who I think he said his name was Will put air in and asked me all the questions someone should about the situation. He said it could get me where I was going but that I would have to keep filling it with air which I didn’t want to worry about. He topped me up with air and I instantly started to look for an Enterprise which was very close by. Thank you to Will and the gentleman at the desk for assisting me when in need. They could have taken me for a ride and charged me a big invoice because I wouldn’t know any better but their honestly and integrity showed. I would highly recommend them and if I lived closer they would be my tire and auto company of choice!

Thank you!!!!”

“I took my Ford Escape for a repair. John who is professional and knowledgeable about the work explained me what needs to be done and how much time needed. As it was a quick fix he told me he don’t need an appointment and did it right away. Great work!”

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 Grimsby? +
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.
