Full Lennox 4-Ton Split System Replacement Done Right

When a system starts giving out, it doesn't just stop cooling or heating - it starts costing you. Comfort drops, energy bills climb, and you're left wondering how much longer it'll hold on. That's exactly the situation we walked into here. The old outdoor condenser and the existing air handler had both run their course.

The before tells the story pretty clearly. The old air handler was worn, wiring was a mess, and the outdoor unit wasn't going to make it much longer. We pulled everything out and started fresh - and that meant doing the prep work right before anything new went in. The new sheet metal plenum base you see sitting in that alcove is a perfect example of that. Clean, properly fitted, built to support the new system the way it should be.

From there we set the new Lennox furnace - a clean, tight fit in that exterior alcove with properly run refrigerant lines and PVC condensate drain routing done neatly. No cutting corners on how it connects to the duct system. That stuff matters for airflow and long-term performance. Then came the new 4-ton Lennox condenser outside, set in the same footprint but looking like a completely different setup.

This is what a proper HVAC installation looks like. Matched equipment, correct sizing, clean line sets, and everything buttoned up so the system can actually perform the way it's rated to. A brand like Lennox already gives you a solid foundation - but the install quality is what determines how long it lasts and how efficiently it runs. We take that seriously on every job.

If your system is getting older and you're starting to notice the signs - inconsistent temperatures, higher utility bills, more frequent repairs - it's worth having a real conversation about replacement options. A well-matched, properly installed system is one of the best investments you can make in your home's comfort and efficiency.
