Matheson Heating Air Plumbing — an 80 year company and 10 time Carrier President’s Award recipient — recently achieved a verified 34 micron vacuum on an air conditioner installation, representing the absolute top tier of refrigerant line preparation in the residential HVAC industry.
Four procedures executed on every installation:
• Nitrogen purge during brazing — prevents oxidation scale that damages compressors over time
• Nitrogen pressure test — verifies zero leaks before refrigerant is introduced
• Deep evacuation verified at 34 microns by Bluetooth micron gauges — removes all moisture that forms acid inside the system
• Vacuum break with nitrogen — final inert purge before refrigerant introduction
Most contractors never use a micron gauge. We verified 34. The real deal on every installation.
