How ac installation works

What a ac installation job looks like in Gresham.

An AC install isn't just dropping a condenser on a pad. We Manual J the home, size the line-set correctly for the run, charge refrigerant by weight to the manufacturer's spec, and verify superheat/subcool on start-up. Triple-evacuation to 500 microns before charging — the step most installers skip.

We install Trane high-SEER systems by default, with American Standard as a value-tier alternative. Same compressor reliability, same warranty parity. SEER2 16–18 is typical — modern minimums are SEER2 14.3 but the efficiency gain pays back inside 5–7 years for most homes.

Outdoor unit on a level pad, line-set routed cleanly with proper insulation, service disconnect sized correctly, vibration pad installed. Quiet operation and long life come from getting these details right.
