YORK® product
YORK® PCG4U
The PCG4U is the ultra-low-NOx variant of York's gas/electric packaged unit — 14 SEER cooling, 81% AFUE heat, with a burner design that sharply cuts nitrogen-oxide emissions for jurisdictions and owners that require it. Same one-cabinet convenience, cleaner combustion. We verify the requirement before you pay the premium; not every application needs it.
Factory-authorized
YORK® PCG4U
The PCG4U is the ultra-low-NOx variant of York's gas/electric packaged unit: the same 14 SEER-class cooling (13.4 SEER / 11 EER listed) and 81% AFUE gas heat as the PCG4, with a burner engineered to sharply cut nitrogen-oxide emissions for jurisdictions and owners that require it.
Low-NOx requirements are spreading — several air-quality districts now mandate them for new gas equipment, and some commercial owners specify them by policy. The PCG4U delivers compliance without changing the one-cabinet installation story: same footprint, same connections, same single-stage scroll simplicity, with sound as low as 72 dBA.
One honest note before you pay the premium: not every application needs it. We verify whether your jurisdiction or project actually requires ultra-low NOx before quoting this unit over the standard PCG4 — and if it doesn't, we'll say so.
Every install starts with a free in-home assessment and a flat written price — no surprises. Call 512-528-4258 or request service online.

Who this model fits
- Projects in jurisdictions with NOx emissions mandates for gas-fired equipment.
- Commercial owners with sustainability specs that call for low-emission combustion.
- Like-for-like PCG replacements where the emissions requirement arrived with the permit.
Warranty
- York: lifetime heat exchanger limited warranty (PCG gas models, with registration) and 10-year parts limited warranty.
- MLD Services: lifetime workmanship warranty — if our install or repair work ever fails, we make it right.
York's extended warranty terms require online registration within 90 days of installation — otherwise parts coverage reverts to 5 years. We register every unit we install as part of the job, so you never have to think about it.
From the field
Owning this system in Central Texas
Ultra-low-NOx burners hold tighter combustion tolerances, so annual combustion analysis isn't optional bureaucracy on this unit — it's how the emissions and the efficiency both stay where the permit says. We log the readings at each visit.
Everything else about owning it matches the standard PCG4: outdoor cabinet care, seasonal changeover checks, and the same one-cabinet service convenience. The premium bought compliance, not complexity.
A note on documentation: low-NOx compliance projects usually require the equipment submittal and combustion records at final inspection. We keep both in your job file and hand copies to your permit holder or GC — chasing paperwork six months later is nobody's idea of a good time.
