Heating and Cooling Systems

Your vehicle’s air conditioning and heating systems are the main contributors to your driving comfort. The complex temperature control systems in the modern cars has the ability heat or cool not only the driver, but allows for separate cooling and heating of the passengers.
These heating and cooling temperatures are adjusted by controls that may be operated by cables, vacuum or electrical switches and motors. Fan speeds are controlled by switches and resistors. They have the ability to heat up, or start cool air flowing. This air flow can also be directed to numerous outlets, to defrost your windshield, warm your feet or send air to the interior. Cabin air filters are common in a large segment of today’s cars and must be replaced on a regular basis to keep the air flowing at maximum efficiency.
Keeping your coolant clean, as the passages in your heater core are the smallest ones in your car, is a major factor in attaining maximum heat out of your system. Also, flushing your coolant system every two years may prevent a costly repair bill of replacing the heater core.
A system that blows hot air, then cold air, may also be caused by low levels of coolant due to a leak in the system, or may be indicative of a head gasket problem in the engine. Our technicians can pressure-test and visually inspect your engine for any signs of leakage. We can also perform a chemical test to determine the potential of a head gasket leak in your motor if no external signs of leakage are located.
Are you experiencing poor heat or no heat, not enough cold air, or low air flow? Have the technicians Dewares inspect your system and keep it working in top performance.
