There is NO typical home central hvac unit. Like fingerprints, all units are created differently. The efficiency (or SEER) varies greatly and the TONS of cooling do to. Between those two intangibles you can vary from about 2 to 8 Lbs. of "freon". There is NO typical home central hvac unit. Like fingerprints, all units are created differently. The efficiency (or SEER) varies greatly and the TONS of cooling do too. This creates two intangibles that cause the refrigerant level to differ quite a bit. Smallish units with a high efficiency rating can be as low as 2 lbs. A large 5 TON system can take as much as 8 lbs. Hire and trust a good HVAC mechanic.
What else can I help you with?
How do you measure freon weight in HVAC?
Freon weight in HVAC systems is typically measured using a refrigerant scale. The scale is placed under the refrigerant cylinder, and the system is charged until the desired weight of refrigerant is reached. The weight of the refrigerant can then be monitored on the scale to ensure proper charging.

Can a central air conditioner hold 9 pounds of freon?
That sounds reasonable to me. I have in my home, a very large (22,000 BTU) through-the-wall air conditioner, designed to cool three large rooms. It uses 3.5 lbs of freon. A whole-house unit I can easily see using as much as 9 lbs.
Does all freon have to be removed when replacing central AC compressor?
Yes. All refrigerant must be recovered and stored when opening up an AC system for service. This is not a DIY task, and should not be attempted by someone untrained in HVAC systems.
How many pounds of HFC-134a refrigerant in a typical HVAC unit?
A typical residential HVAC unit contains around 4-10 pounds of HFC-134a refrigerant, depending on the system size and capacity. Commercial HVAC units may contain more refrigerant.
Why isn't the air conditioner blowing cool air?
Is it a central unit? check and see if the fan and compressor are running in the outdoor unit. The system may be low on freon or the compressor may not be running. It is best to call a qualified HVAC technician.
