Geothermal Performance Service, Georgetown TX
A geothermal performance service is a comprehensive evaluation and tuning of your entire geothermal system, from ground loop fluid condition and flow rate through refrigerant circuit performance to electrical system health. The goal is to ensure your system is delivering the efficiency it was designed for, not just functioning.
Geothermal systems can lose 15-25% of their designed efficiency without any obvious malfunction, gradual loop fluid degradation, minor refrigerant charge loss, or slowly declining circulation pump performance are common culprits. A performance service catches and corrects these before they become comfort problems.
Signs You Need Geothermal Performance Service in Georgetown
- ⚠Utility bills that have crept up gradually over several years without an obvious cause
- ⚠Longer run times than the system needed when it was newly installed
- ⚠Temperature swings that feel larger than they used to before reaching setpoint
- ⚠It's been more than a year since the system's full performance was checked
What's Included
Measure entering/leaving water temperatures and flow rate under operating conditions.
Test and correct loop fluid chemistry for optimal heat transfer and corrosion protection.
Measure and verify refrigerant charge, superheat, and subcooling against manufacturer specifications.
Test all electrical components for performance degradation, capacitors, contactors, control boards.
Verify airflow, filter condition, and coil cleanliness on the indoor air handler.
Documented before/after measurements with efficiency calculations.
Georgetown TX Considerations
A geothermal system's efficiency advantage depends on the ground loop, heat exchanger, and refrigerant circuit all performing at their designed capacity, and small losses in any one of those areas compound gradually rather than causing an obvious failure. A performance service checks loop flow rate, refrigerant charge, and heat exchanger efficiency together against the system's original specifications, catching the kind of slow efficiency drift that shows up as a higher electric bill long before it shows up as a system that stops working. We provide a written summary of all measurements taken, giving homeowners a documented baseline to compare against at next year's service.
A full performance service measures loop flow rate, refrigerant subcooling and superheat, and heat exchanger approach temperature, comparing each against the system's original commissioning data where available, or against manufacturer specifications when it isn't. Catching a small efficiency loss in any one of these areas early, before it compounds with losses elsewhere, is what keeps a geothermal system performing close to its designed efficiency for the full life of the equipment rather than gradually drifting toward the performance of a conventional system while still carrying the geothermal price tag. We recommend this service annually for Georgetown geothermal systems given how much compressor runtime they see during the area's long, hot cooling season.
