Heating and AC Services in
Hemlock, MI

Your vehicle’s heating and air conditioning system is more than just a comfort feature—it contributes to safety and efficiency. A faulty heater can affect windshield defrosting and visibility in winter, while a malfunctioning AC can leave you sweating and distracted in summer. Over time, components like compressors, blower motors, thermostats, and refrigerant lines wear down, leak, or fail completely. These issues don’t just affect temperature—they can also reduce fuel efficiency and cause further strain on your engine.

That’s why having your system inspected and repaired by a professional is so important. At Hemlock Auto & Alignment, we go beyond basic recharges or quick fixes. Our technicians perform comprehensive diagnostics to determine the root cause of heating or cooling issues, whether it’s a refrigerant leak, a failing compressor, or an electrical fault. We use precision tools to detect leaks and test pressure levels, ensuring your system operates at peak performance.
