How do you install Freon in an AC unit?

Adding refrigerant (commonly referred to as “Freon”) to an AC unit is a technical task that should only be performed by a licensed HVAC professional. Refrigerant levels must be carefully measured and added using specialized tools to ensure proper pressure and system balance. Overcharging or undercharging refrigerant can cause significant damage to your system and lead to costly repairs—or worse, system failure. If you suspect a refrigerant issue, Mainstream’s certified technicians can inspect your system, check for leaks, and safely recharge it to manufacturer specifications.
