Testo digital manifolds and micron gauges
Digital manifolds such as the Testo 557s read system pressures, temperatures, superheat and subcooling at the same time. A wireless micron gauge confirms the vacuum level before refrigerant goes back in.
How we work
Pro tools. Factory procedures.
We measure before we replace anything, follow the manufacturer's service procedure for your model, and use original parts where available.
1. Professional-grade diagnostic tools
The tools in our van, and what each measurement does for you.
CPS vacuum pumps, recovery and leak detectors
Vacuum pumps pull a deep vacuum, recovery equipment removes refrigerant safely instead of venting it, and electronic leak detectors track down where refrigerant is escaping.
Fieldpiece meters, probes and manometers
Clamp meters and multimeters check motors, compressors and controls; temperature probes measure supply and return air; manometers check gas pressure and airflow.
What those readings mean for you
Correct charge, to spec
Refrigerant is charged to the manufacturer's target using superheat and subcooling, not by guesswork. A correct charge cools properly, uses less power and is easier on the compressor.
Deep vacuum removes moisture
Moisture and air left in a sealed system cause acid, ice and early compressor failure. We pull a deep vacuum and verify it on a micron gauge before recharging.
The real leak, found
If a system is low on refrigerant, there is a leak. We look for where it is, so you are not paying to top it off again next season.
Readings you can see
We can show you or text you the readings before and after the repair, so you know what was wrong and that it was fixed.
2. Manufacturer service procedures
Repairs and maintenance follow the manufacturer's service manual and specifications for your model: diagnostic steps, error codes, torque and clearance specs, refrigerant type and charge, and test values. When the manual calls for a specific test before a part is replaced, we do that test first.
3. OEM or manufacturer-approved parts
We use original (OEM) or manufacturer-approved parts where they are available. They fit the way the unit was designed and keep it working to its original specification. If an original part is not available or is on backorder, we explain the options before going ahead.
