Restore Comfort in Any Weather

AC & Heating Repair in Columbia, South Carolina

When summer heat settles over Columbia and your vehicle's air conditioning blows warm air, or winter mornings leave you scraping frost off the windshield because your heater does not work, driving becomes uncomfortable fast. T&G Auto Repair LLC provides full inspection and repair of vehicle heating and cooling systems, addressing refrigerant leaks, compressor failures, blower motor issues, and airflow blockages. Daily driving in Columbia means you rely on climate control year-round, and a failed system strains both your comfort and your engine's performance.

AC and heating repairs begin with diagnosing the source of the problem, whether it involves the compressor, condenser, evaporator, blower motor, or cabin air filters. Technicians check refrigerant levels, inspect hoses and seals for leaks, and test electrical components that control system operation. Refrigerant leaks are common in older vehicles, and low refrigerant reduces cooling capacity. Heating problems often involve stuck blend doors, clogged heater cores, or failed thermostats that prevent hot coolant from reaching the cabin.

If your cabin temperature is uncomfortable or airflow is weak, schedule AC or heating service in Columbia to address the issue before driving conditions worsen.

How Climate Control Repairs Work

Your vehicle arrives in Columbia, and a technician inspects the AC or heating system to identify what is causing weak airflow, warm air, or no air at all. Refrigerant levels are checked using a gauge set, and UV dye may be added to trace leaks in hoses, seals, or the evaporator. Heating systems are tested by checking coolant flow, thermostat operation, and blend door movement.

After repairs are completed, you will notice strong, cold airflow in summer and warm air that quickly defrosts windows in cooler weather. Cabin temperature stabilizes at your selected setting, and the system runs quietly without strange noises or odors. Proper climate control prevents strain on related engine components and keeps driving conditions comfortable regardless of outside temperature.

Repairs may include recharging refrigerant, replacing compressors or condensers, cleaning or replacing cabin air filters, or fixing electrical issues that prevent the blower motor from operating. Some problems require removing dashboard components to access the evaporator or heater core, which increases labor time. Not all AC issues involve expensive parts; sometimes a clogged expansion valve or dirty condenser is the only problem.

Climate Control Questions Come Up Often

Drivers typically want to know why their AC stopped working suddenly, or whether a weak heater means their engine has a problem.

What causes AC to blow warm air?
Warm air usually means refrigerant is low due to a leak, or the compressor is not engaging. Both issues prevent the system from cooling the air before it enters the cabin.

How long does an AC repair take?
Simple repairs like recharging refrigerant or replacing a cabin air filter take less than an hour. Compressor or evaporator replacement requires several hours due to the disassembly involved.

Why does my heater take so long to warm up?
A slow heater often means the thermostat is stuck open or coolant levels are low. Both conditions prevent the engine from reaching proper operating temperature quickly, delaying cabin heat.

Can a failing AC system hurt my engine?
A seized compressor can strain the serpentine belt and related pulleys, potentially causing the belt to snap. Low refrigerant does not harm the engine, but ignoring leaks allows moisture into the system, which damages internal components.

How often should I service my AC system?
You should have the AC system inspected annually, especially before summer heat arrives in Columbia. Regular checks catch small leaks and worn components before they cause complete system failure.
