AC System Diagnostics and Repair:
We use diagnostic tools like pressure gauges, leak detectors, and OBD scanners to identify issues such as low refrigerant, electrical faults, and component failures in air conditioning systems. Once the problem is pinpointed, we fix leaks, replace faulty parts like valves and sensors, and testing the system to ensure proper cooling performance.
Refrigerant Recharge or Refill:
We evacuate any remaining refrigerant from the AC system using a recovery machine to prevent environmental release. We then check for leaks, add the correct amount of new refrigerant (like R-134a or R-1234yf) along with compressor oil, and verify the system's pressure and operation.
Heater Core Repair or Replacement:
To address a heater core, we first drain coolant from the system. We often remove the dashboard or accesses the core under the hood, disconnect hoses, and either flush/repair the core if clogged or replace it entirely. We then reassemble the system, refill with coolant, and test for heat output and leaks.
Thermostat Repair or Replacement:
To repair thermostats we first drain the engine coolant to access the thermostat housing, typically located near the radiator hose. The old thermostat is removed, inspected for sticking or failure, and replaced with a new one matched to the vehicle's specifications. Then coolant is then refilled, and the system is bled of air before we test the engine temperature regulation.
Blower Motor Repair or Replacement:
Accessing the blower motor usually requires removing the glove box or dashboard panels. We disconnect electrical wiring and mounting bolts, test the motor for faults like worn bearings or failed resistors, and either repair it or install a new one. The assembly is then reinstalled and tested for fan speeds and airflow.
Climate Control Module Repair:
We scan the vehicle's computer for error codes related to the climate control unit. If the module is faulty (e.g., due to electrical issues or software glitches), it's removed from the dashboard, repaired by fixing circuits or reprogramming, or replaced with a compatible unit. We then make sure the system is recalibrated and tested for proper temperature and fan control.
Compressor Replacement:
When replacing a compressor we first recover the refrigerant to safely depressurize the system. We then remove drive belts, electrical connections, and refrigerant lines from the old compressor, which may be seized or leaking. A new compressor is installed with fresh O-rings and oil before the system is vacuumed to remove moisture. Finally, we recharge the system with refrigerant and test for efficient operation.
Evaporator and Condenser Cleaning or Replacement:
For cleaning, we use specialized foams and brushes to remove debris, mold, or corrosion from the evaporator (inside the cabin) or condenser (front of the vehicle). If replacement is needed, we recover refrigerant, disassemble components (e.g., removing bumpers for the condenser), swap out the old unit for a new one, and then reassemble and recharge the system before doing performance checks.
Hose, Line, and Belt Inspections or Repairs:
We conduct visual and pressure tests to check for cracks, leaks, or wear in AC hoses, refrigerant lines, and drive belts. Faulty parts are replaced by disconnecting fittings, installing new sealed components with proper torque, and lubricating belts if needed. We then pressurize and inspect the system to ensure no leaks and smooth operation.
Comprehensive System Inspections and Maintenance:
Using gauges and scanners we check all AC/heating components for pressures, leaks, electrical integrity, and fluid levels. For maintenance we clean filters, lubricate moving parts, tighten connections, and top off fluids. Any issues found are addressed, followed by a full system test to confirm optimal cooling, heating, and efficiency.
Coolant Flush or Radiator Service:
We drain old coolant from the radiator and engine block before a flushing solution is circulated to remove contaminants, scale, or sludge, followed by a rinse of water. New coolant mixture is then added, the system is bled to remove air pockets, and the radiator is inspected or repaired (e.g., fixing fins or leaks) before we verify proper circulation and temperature control.
Have questions about your vehicle's AC or heating system? - Ask an expert!
Our experienced AC mechanics have the answers you need
Why is my car's AC blowing warm air?
This issue often stems from low refrigerant levels caused by leaks in hoses, seals, or the condenser, which reduces the system's ability to cool air effectively. Other common culprits include a malfunctioning compressor that fails to circulate refrigerant properly, clogged cabin air filters restricting airflow, or electrical problems like faulty sensors or relays disrupting the system's operation.
To prevent further damage and ensure optimal performance of your AC system, bring your car up to Village Auto Service and have a certified technician perform a diagnostic using pressure gauges and leak detectors to pinpoint the exact cause and recommend repairs.
How do I know if my car AC needs a recharge?
Key indicators that your AC needs a recharge include reduced cooling with the AC blowing lukewarm or warm air, weak or inconsistent airflow from the vents, unusual hissing or bubbling noises suggesting refrigerant escaping, or the AC clutch not engaging when activated.
While a recharge can temporarily restore function by adding refrigerant like R-134a or R-1234yf, it only treats the symptom. Underlying leaks must be inspected and repaired first using UV dye or electronic detectors to avoid refrigerant loss recurrence and potential compressor failure from low oil levels.
Why is my car's heater blowing cold air?
Heaters blowing cold air arises from insufficient coolant levels due to leaks in the radiator, hoses, or water pump, preventing hot engine coolant from reaching the heater core. A thermostat stuck in the open position can cause the engine to run too cool. A clogged heater core from sediment buildup can also block heat transfer.
We begin troubleshooting by safely checking the coolant reservoir when the engine is cool and topp it off with the manufacturer-recommended mixture. If issues persist, flushing or component replacement may be required.
How often should I service my car's AC and heating system?
Depending on your vehicle, we recommend servicing every 12 months or 19,000 to 24,000 kilometers, whichever comes first.
We include comprehensive inspections of refrigerant levels, pressure testing for leaks, cabin and engine air filter replacements, and checks on components like the compressor, blower motor, and thermostat. This preventive maintenance helps detect early issues such as minor leaks or wear, improves fuel efficiency by reducing system strain, and extends the lifespan of parts, ultimately avoiding costly breakdowns during extreme weather conditions.
