From temperature control to charging systems, we diagnose and repair the components that keep your engine protected, your cabin comfortable, and your vehicle dependable.

Comfort in the Cabin, Confidence on the Road

Your cooling, heating, and electrical systems all play critical roles in keeping your vehicle reliable. At Tom Dwyer Automotive Services, our ASE-Certified Technicians inspect, diagnose, and repair these systems with precision and care – helping you avoid breakdowns, overheating, electrical failures, and comfort issues in any season.

Cooling System Care

Your cooling system keeps engine temperatures stable and prevents costly internal damage. We monitor coolant flow, pressure, and component performance to keep your engine protected.

Heating & Cabin Comfort

Your heater relies on coolant flow and climate components that also influence engine temperature. We restore heat, clear fogged windows, and ensure proper HVAC performance.

Electrical & Charging Systems

From starting the engine to powering safety features, your electrical system must deliver dependable voltage every time. We diagnose battery, alternator, starter, and wiring issues before they leave you stranded.

Cooling/Air Conditioning

Your cooling system includes components such as the radiator, hoses, thermostat, water pump, and cooling fans – all working together to maintain safe engine temperatures. Even small leaks or failing parts can lead to overheating and extensive engine damage. We evaluate cooling performance, pinpoint weak components, and make repairs that restore proper operation.

The Tom Dwyer Way

We inspect your cooling system end-to-end, looking for leaks, flow restrictions, failing sensors, deteriorated hoses, and worn pumps or thermostats. When repairs are needed, we use reliable, high-quality components to ensure durable, long-term engine protection.

Heating & Cabin Comfort

Your vehicle’s heating system depends on hot coolant circulating through the heater core. When that flow is restricted or the core becomes clogged or damaged, cabin heat disappears and windows fail to defrost effectively. We diagnose the cause and restore consistent, dependable heat.

The Tom Dwyer Way

We test coolant flow, inspect the heater core, evaluate blend doors and HVAC controls, and identify the source of lost heat or fogging. Repairs are made with long-term reliability in mind.
