If your vehicle's air conditioning isn't cooling like it used to, Hitech Auto Electrical & Mechanical can help. We recommend servicing your air conditioning every 12 months, because most systems slowly lose gas through hoses, O-rings and seals.
Signs your air conditioning needs a service
- Blows hot air even with the dial on cold
- The air doesn't feel as cold as it used to
- Randomly blows colder than you set it
- It makes loud noises
- Unpleasant odours from the vents
Our AC performance check includes
- Identify the type of gas in the system
- Diagnose and repair all air conditioning problems
- Convert pre-1994 vehicles from old CFC R12 gas to new R134a gas
- Remove and replace the filter unit if necessary
- Check the compressor and condenser unit
- Check all hoses and wiring harnesses
- Pressure test the system
- Vacuum the system for a minimum of 30 minutes
- Recharge with R134a refrigerant, fluoro dye and oil
- Leak test all components
- Carry out pressure and temperature testing
- Eliminate bad odours and repair climate control systems
What can go wrong
Not using your air conditioning over winter causes internal seals to dry out and leak. Switching the system off also allows condensation to build up, creating an ideal breeding ground for bacteria and mould spores — which is where odours come from.
Anti-bacterial clean & pollen filters
A fresh pollen filter ensures optimal protection from dust, pollen and harmful exhaust emissions, good-quality filtered air, and windscreens that don't mist up in autumn and winter.
