Why is my AC compressor squealing?

If your air conditioning unit is emitting a high-pitched screeching or hissing sound, the most likely cause is high pressure built up in your compressor. If this is the case, the sound will most likely be heard outside at the unit when the AC first kicks on and will last about 10-15 seconds.

4. Add or expand grilles and registers.
5. Replace existing registers and grilles with high velocity models.

Why is my Honda Accord not blowing cold air?

Over time, refrigerant can leak from the AC system through seals. If the AC does not have enough refrigerant, it will not blow cold air.

These cannot be interchanged.

How does the a / C system in a Honda Accord work?

Your A/C may not be in the best shape to perform. As air runs through a series of tubes and components of the A/C system, the evaporator removes hot air from inside the cabin to turn it into frigid, cool air. During that process, the evaporator also produces condensation, which is then dripped through a tube and released underneath the car.
