HVAC (A/C & Heating)

At Unitech Auto Repair & Smog, Inc., we provide comprehensive HVAC services to keep you comfortable year-round in Sacramento's diverse climate. From scorching summer heat to chilly winter mornings, our certified climate control specialists ensure your vehicle's heating and cooling systems perform flawlessly in all conditions.

Our HVAC (A/C & Heating) Services Include:

• A/C Recharge (R-1234YF freon available): Our A/C recharge service goes beyond simply adding refrigerant – we conduct a complete system performance test, check for leaks using electronic detectors and UV dye, and ensure proper operation of all components. We're fully equipped to service both traditional R-134a systems and newer, more environmentally friendly R-1234YF systems required in many late-model vehicles. This comprehensive approach ensures your A/C delivers maximum cooling performance during Sacramento's intense summer heat waves when temperatures regularly exceed 100°F.
• Heater Core Service: Sacramento's winter mornings can be surprisingly cold, making a properly functioning heater essential. Our heater core service includes thorough inspection for leaks, flow testing, and flushing to remove corrosion and deposits that restrict heat transfer. For vehicles requiring heater core replacement, our experienced technicians efficiently complete this complex repair with minimal dashboard disassembly, restoring full heating capacity and eliminating coolant odors from your cabin.
• Blower Motor Replacement: When your blower motor fails or becomes noisy, we provide expert replacement using OEM-quality parts that match your vehicle's specifications for airflow and noise levels. Our technicians also inspect and clean the blower motor resistor, ductwork, and air intake, ensuring proper airflow distribution throughout your vehicle's cabin – essential for both heating and cooling performance in Sacramento's variable climate conditions.
• Cabin Air Filter Replacement: Sacramento's agricultural surroundings and urban environment create unique air quality challenges. Our cabin air filter service includes removal of the old filter, cleaning of the housing, and installation of premium filters that trap pollen, dust, and pollutants. We offer standard particulate filters and activated carbon filters that eliminate odors – particularly beneficial during wildfire season when air quality in the Sacramento region can be compromised.
