Car AC and Heat Repair in South Windsor, CT
Short answer: warm air from the AC is usually a refrigerant leak, a bad compressor or a failed fan. No heat at idle is often low coolant from a leak or air in the system.

Does this sound familiar?
- The AC blows warm or weak air
- No heat, or heat only when driving fast
- A sweet smell inside the car, which can mean a heater core leak
- Foggy windows that won’t clear
- A musty smell from the vents
- Strange noises when the AC turns on
How we handle it.
No heat is often a coolant problem. The Audi in our photos had no heat at idle. Older coolant lines on top of the engine had turned brittle and were leaking, and the wrong coolant had been added. We replaced the lines, flushed the system and refilled it with the right coolant, all the same day.
For AC, a recharge only helps if there’s no leak. We check for leaks and test the compressor and fans so the cold air lasts.
Repairs carry a 3 year, 36,000 mile warranty. Drivers come from Manchester, Vernon, Glastonbury and Windsor for AC and heat repair here.
No heat at idle, fixed the same day.
