Refrigerant is responsible for transferring the heat inside your home to the exterior. This is where the hot air blows out of your AC over the coils. Without refrigerant, there will be no air conditioning. If you have a leak in your system, the refrigerant will slowing leak out and your system will not blow cool air. Our ac techs can detect leaks and stop them. We can also “charge your air conditioning unit” and refill if necessary.
