How We Find and Fix Efficiency Losses
Efficiency optimization targets the gap between a system's rated capacity and what it actually delivers to your home. A 4-ton, 16 SEER2 condenser only performs like a 16 SEER2 unit when the refrigerant charge is correct, the coils are clean on both sides, airflow across the evaporator matches the equipment's design specification, and the ductwork delivers that air without excessive leakage. In practice, most systems in Williamson County that are five or more years old are losing measurable capacity to one or more of these factors, even though nothing has technically "broken."
We start by measuring, not guessing. That means checking superheat and subcooling against manufacturer targets for the outdoor temperature and comparing them to the nameplate charge, checking temperature split across the evaporator coil (a properly charged, properly loaded system in Georgetown summer conditions should produce roughly 18 to 22 degrees of split), and checking static pressure on both the supply and return sides of the air handler. A dirty condenser coil alone can raise head pressure and compressor amp draw enough to cut delivered efficiency by 10 to 15 percent, and a slightly overcharged or undercharged system compounds that loss further.
Once we have real numbers, the fix is targeted rather than a blanket recommendation. That might mean a chemical coil cleaning if fin surfaces are coated in Central Texas dust and cedar pollen, an adjustment to refrigerant charge using weighed-in methods rather than just pressure readings, a filter and blower wheel cleaning if static pressure is high on the supply side, or duct sealing if we find the return side pulling in attic air through gaps at boots and plenum connections. Homes built during Georgetown's rapid growth periods in the 1990s and 2000s commonly have ductwork run through 130 to 150 degree summer attics, and even small leaks there translate directly into wasted cooling capacity and higher run time.
The result of an efficiency optimization visit is a system that reaches its rated performance more closely, which shows up as shorter run times for the same comfort level and a lower percentage of total home energy going to HVAC. We document before and after readings so the improvement is something you can see in numbers, not just take on faith, and any parts replaced (a capacitor, a contactor, a badly corroded coil section) come with the standard ProAir parts and labor warranty.
