Refrigerant is the lifeblood of your air conditioner.
A leak is one of the most common reasons your system stops cooling in North Texas summers.
Refrigerant is a special chemical that absorbs heat inside your home and releases it outside. It cycles through the evaporator coils, compressor, and condenser — never “used up.” If it leaks, your AC can’t remove heat efficiently and you get warm air.
System runs but never gets cold.
Low pressure causes freezing (see our Frozen Coils guide).
System works harder and longer to cool your home.
Refrigerant escaping from lines or coils.
AC never seems to shut off.
Refrigerant carries compressor oil — a tell-tale sign.
Years of vibration loosen fittings and solder joints.
North Texas moisture eats away at copper lines.
Improper brazing or damaged coils from the start.
Common in homes with attic or crawl-space units.
It is illegal for homeowners to buy or add refrigerant (R-410A or R-22) without EPA Section 608 certification. Simply “topping off” hides the leak and will cause the problem to return — often damaging your compressor.
