Lennox Two-Stage AC Replacement in NW Portland

Here's what we were working with - an aging single-stage AC unit that was doing its best but struggling to keep up. Single-stage systems are either fully on or fully off. No in-between. That means hard starts, uneven temps throughout the house, and higher energy use every time the system kicks on.

We replaced it with a new Lennox two-stage unit. The difference matters more than most people expect. A two-stage system runs at a lower capacity most of the time, only ramping up to full power when conditions actually call for it. The result is more consistent cooling, quieter operation, and less wear on the equipment over time.

That constant cycling you hear with older units - on, off, on, off - is hard on the system and hard on your energy bill. Two-stage operation smooths all of that out. The unit runs longer at a lower speed, which also does a better job pulling humidity out of the air. In a place like Portland, that matters.

When your AC has to work harder and harder just to keep up, repair costs start stacking up fast. At some point, replacement makes more financial sense than patching an old system that's past its prime. This homeowner made the right call, and now they've got a reliable, efficient setup that's built to handle Pacific Northwest summers for years to come.
