A/C, Heating & Cooling
Stay comfortable in every season.
A/C recharge, leak detection, compressor service, and heating system repair for Michigan weather.
Overview
Michigan demands both heat and cold performance from the same vehicle. When your A/C blows warm in July or your defrost barely clears the windshield in January, the problem is rarely just low refrigerant — it's a leak, a failed compressor clutch, a clogged condenser, or a stuck blend door.
Jack's evacuates and recharges to factory spec, uses leak detection dye and electronic sniffers, and repairs the root cause so you're not paying for refrigerant every summer.
Cooling system service ties directly to engine health. We inspect hoses, water pumps, and thermostats alongside HVAC work so overheating doesn't surprise you on I-75.
How Jack's approaches this
- Electronic leak detection before recharge — no annual top-off treadmill
- Compressor, condenser, and evaporator diagnosis with manifold gauges and scan data
- Heater core and blend-door access planned with clear labor estimates
- Coolant system inspection integrated with every overheating complaint

Why Jack's
We won't just top off refrigerant and send you home. Sam's team finds why it leaked — or you'll be back next month paying again.

Michigan drivers
Summer humidity loads condensers; winter salt corrodes condenser fins. We inspect front-end airflow every HVAC visit.
