Frequently Asked Questions

Why is my car's A/C not blowing cold air?

Your A/C may be low on refrigerant, leaking, or dealing with a problem in the compressor, condenser, evaporator, blower, or electrical system. We can inspect the system and recommend the right repair.

Do you offer A/C recharge services?

Yes, we provide A/C recharging along with A/C repairs. We can also check for leaks or other problems that may be causing the system to lose cooling performance.

Why is my car heater not working?

Heater problems can come from low coolant, thermostat issues, heater core problems, blower motor trouble, or cooling system concerns. We can diagnose the system and find out why the cabin is not getting warm.

Can heating and cooling problems cause engine overheating?

Yes, the vehicle’s cooling system helps regulate engine temperature. If parts like the radiator, water pump, hoses, or thermostat fail, your engine may overheat.

Do you repair radiators and water pumps?

Yes, we repair and replace radiators, water pumps, hoses, and other cooling system parts. These components are important for keeping your engine at the right temperature.

What are the signs of a bad heater core?

Signs may include poor heat, a sweet smell inside the cabin, foggy windows, or coolant leaking onto the passenger-side floor. We can inspect the heater core and related parts to confirm the issue.

Do you service evaporator cores?

Yes, we handle evaporator core concerns as part of our heating, cooling, and A/C services. If your A/C is weak or not cooling properly, we can inspect the system and locate the problem.

When should I get a coolant flush?

Coolant flush timing depends on your vehicle and manufacturer recommendations. We can check your coolant condition and let you know whether a flush or replacement is needed.

Is A/C repair covered by a warranty?

Most parts and labor come with a 1-year warranty when you bring your vehicle to us. We can explain what is covered before work begins.

Should I service my HVAC system before summer or winter?

Yes, seasonal checks can help you avoid uncomfortable driving and unexpected repairs. We can inspect your A/C before hot weather and your heating system before colder months.

Handling the Smaller Jobs Too

Not every heating or cooling issue requires major repairs or component replacement.

Using advanced diagnostics and professional tools, our skilled technicians at Grewal’s Automotive can pinpoint the exact problem. We also take care of smaller jobs like radiator flushes, coolant replacement, and A/C recharging.
