The best ways to tell if your heating and A/C are having problems:
- If your A/C blows just a little cooler than the air outside
- Air that blows in smells moist, musty, or like mildew
- Your cabin does not heat up in cold weather, or is just somewhat warmer than outdoors
- The defroster takes longer than normal to function, blows in filthy air, or doesn’t operate
- Your heater or A/C only operates when driving, not when idling, or stops blowing when the vehicle is still
- Your heating unit blows chilly air, or the air conditioning blows warm
- At the highest setting, your vents do not put out much air
An in-depth inspection of heating and a/c systems includes:
- Checking the interior and blower
- Checking radiator coolant level, hoses, pressure cap and thermostat
- Screening the compressor belt
- Examining for cracks or additional damages.
- A cooling system pressure examination
- Contrasting the air conditioning pressure to produce specifications
- Examining the air conditioning system for refrigerant leaks
- Check the interior vent air temperature
