The tonnage on the old unit is not the answer
Most replacements get sized by looking at the rating plate of the dying unit and ordering the same. But the old unit was often oversized the day it went in — and an oversized system is the single most common reason an Erie home cools to temperature while the air stays damp. Short cycles drop the thermostat but never run long enough to pull water from the air. The fix happens before the order: a load calculation on the actual house, so the new system runs the long, steady cycles that make a lake-plain summer livable.
What installation day looks like
The old system comes out and gets hauled away — refrigerant recovered properly, not vented. The new condenser sets level on a fresh pad, the coil matches the furnace or air handler it’s paired with, and the lineset gets pressure-tested before the charge goes in. Then the part that separates a real install from a swap: commissioning. Charge verified against manufacturer spec, airflow measured and set, temperature split confirmed across the coil. Most replacements run a single day, and you walk the thermostat and filter routine with the tech before the van leaves.
When replacement beats repair
The honest line: age plus the repair’s size. A capacitor on a nine-year-old system is a repair. A compressor on a sixteen-year-old R-22 unit is a down payment on a system that will fail again — refrigerant for those climbs in price every season. When the math is close, you get both numbers side by side in writing, with the efficiency difference spelled out in plain terms. The decision is yours; the information shouldn’t be the hard part.
