Homeowners often search for AC Freon charging when the system is running but not cooling, blowing warmer air, freezing up, or making the electric bill climb. Refrigerant is part of the cooling system, but those symptoms do not automatically mean the charge is low. A dirty filter, dirty outdoor condenser coil, dirty evaporator coil, restricted ductwork, or blower problem can create similar symptoms by reducing airflow or heat transfer.
More serious mechanical problems can also resemble a bad refrigerant charge. A compressor with internal bypass may run without pumping refrigerant correctly. Electrical problems, metering-device restrictions, and failing motors can also affect pressures and temperatures. That is why we check airflow, temperature split, refrigerant performance, electrical components, and compressor operation before recommending a refrigerant charge.
Refrigerant is not fuel and a properly sealed system should not use it up. If refrigerant needs to be added, there is a leak or the system was not charged correctly before. When practical, we can explain the cost and tradeoffs of adding enough refrigerant to keep an older system operating for a while. We can also complete a comprehensive leak search, repair or re-weld an accessible leak, or replace a leaking component.
When a severe leak or major equipment failure makes repair a poor investment, TradeStrong can provide clear replacement options. Our Lennox AC replacement options include dependable single-stage, two-stage, and variable-speed systems. Yearly checks cannot prevent every failure, but they can reveal developing problems before they become a more costly summer breakdown.
