Rooftop Package Unit Swap - Old Rheem Out, Lennox 5-Ton 2-Stage In

Here's what a worn-out rooftop system looks like when it's been fighting a losing battle for too long. The old Rheem Classic package unit had rust streaking across the roof decking, corroded connections, and visible wear that told the whole story. When a unit gets to this point, it stops being an HVAC system and starts being a liability.

Getting a unit this size off a commercial rooftop isn't a two-man-and-a-ladder kind of job. We brought in a crane to lift the old unit off and set the new Lennox 5-ton 2-stage package unit in place. That's just the right way to do it - no shortcuts, no improvising.

The Lennox 2-stage unit is a meaningful upgrade over a straight single-stage system. A 2-stage compressor runs at a lower capacity most of the time, only ramping up to full power when conditions demand it. That means more consistent temperatures inside the building, less stress on the system, and lower energy costs compared to a unit that just hammers on and off at full blast all day.

Once the new unit was set on the existing curb frame and connected to the ductwork, we made sure everything was properly tied in and running clean. No half measures. When you're doing a commercial HVAC installation, every connection point matters - because a problem up on the roof doesn't stay on the roof. It shows up as comfort complaints, high utility bills, and emergency calls at the worst possible time.

This is the kind of HVAC installation work we do - diagnose the real problem, spec the right equipment, and install it correctly. If your rooftop unit is showing signs of age or causing issues for your building, it's worth having someone take a real look before it becomes a bigger headache.
