Version 1.45 brings significant reliability improvements based on direct feedback from field technicians. Replace on Burnout (ROB) Projects ROB projects now complete the full workflow successfully. A crash that occurred when entering air handler phase has been resolved. Field Review Field technicians can now finish Field Review when a flagged Test-Out snapshot requires variance notes. The variance text field now renders correctly in all conditions, eliminating a workflow blocker reported in the field. Electrical Readings Two separate issues causing misreported electrical errors have been corrected, improving calculation accuracy across all project types. PDF Report Accuracy Air handler watts now correctly include power factor in both Test-In and Test-Out report calculations. Test-Out relative humidity calculations have been corrected. Photos Photo thumbnails display reliably. The photo picker no longer loses a selected photo. Filter Before/After photos now attach correctly. Invoice NaN display errors in invoice calculations have been eliminated. Customer name, address, and contact details now populate correctly. Measurements & Gauges Supply Air Wet Bulb Temperature now displays correctly in live gauges and diagnostic snapshots. Superheat gating in multi-circuit systems has been corrected. Measure date is now always recorded. Nominal capacity now uploads correctly to the database. Equipment Data Condenser serial and model numbers now save and persist correctly between sessions. Thermostat project “Add Equipment” no longer carries over condenser model number, serial, and sticker ID from the previous unit. New: Vane Anemometer in Quick Test Airflow testing now includes vane anemometer measurement in the Quick Test screen. Other Improvements Probe connection indicators no longer appear when no probes are connected. Pre-Clean workflow improvements. Tonnage selection list corrected for large-tonnage units.

New features and enhancements Smarter Project Setup: We've streamlined the project setup process by consolidating residential and commercial classifications, making it easier and more intuitive to get started. Enhanced Stability Indicator: The stability indicator is now more robust! We've implemented new logic to lock out test-in and test-out snapshots and provide clearer feedback on system stability with real-time delta pressure and timer displays. Improved Refrigerant List: Finding the right refrigerant is now quicker! The 12 most common refrigerants are now prominently displayed at the top of the list, followed by the rest in alphanumeric order. Simplified Field Review: We've removed the "remaining useful life" slider from the field review section for a cleaner, more focused experience. Precise Geotagging: CoolSaver now ensures that only the building number is captured for addresses, preventing the entry of address ranges and improving accuracy. Clearer Model and Serial Number Wording: We've updated the wording for model and serial number entry to provide more clarity on where to find this information. Advanced Field Review Logic: We've replaced the amps/ton rule with a new condenser power rule in the field review section, providing more accurate assessments for both test-in and test-out measurements. Comprehensive M&V Project Handling: For M&V projects, measurements will no longer clear until all corrective measures are completed, ensuring thorough and accurate project tracking.
