  • Sticky Indoor Air. An overcharged air conditioner may end up affecting your indoor air quality in terms of humidity as well.
  • Excessive Condenser Heat.
  • Non-Functioning Air Conditioner.

What happens when AC gas is high?

An overcharged AC will show higher than normal pressure and temperature readings. The compressor works harder to try balancing out the system, which results in more pressure. This causes even more pressure to build, resulting in a cascade failure of cooling capacity.
