Here’s something most homeowners never hear: the majority of AC systems never actually achieve the SEER efficiency rating they were sold. More than 65% of residential systems are improperly installed and perform below their potential — one study measured real-world performance at just 59 to 84% of rated SEER. The reason almost always comes down to one crucial, often-rushed step: the startup.

Most companies simply pull a vacuum and release the factory refrigerant charge — and call it done. We don’t. First, we set the airflow at the blower and check static pressure, because low airflow and incorrect charge are the exact faults that rob a system of its efficiency. Then we put the system into a 15-minute cooling test run, letting the pressures settle for an accurate reading. Finally, we dial in the refrigerant by measuring superheat and subcooling, charging to the manufacturer’s exact specification. No system comes from the factory with the precise charge your home and line set require — and getting it right is the difference between a system that simply runs and one that delivers the efficiency, comfort, and lifespan you paid for.
