A replacement quote that starts by reading the tonnage off your old nameplate is copying whatever the last contractor guessed. We size from a load calculation on the actual house — square footage, window area, insulation, orientation, and the duct system that has to carry the air. An oversized condenser short-cycles, never runs long enough to pull humidity out, and leaves the house cold and clammy through an Oklahoma July. Oklahoma sits in the DOE South region, so any new split-system air conditioner installed here has to meet 14.3 SEER2 and 11.7 EER2. The northern minimum is 13.4 SEER2, which means equipment that is legal to install new in Ohio cannot go in your house. SEER2 is also tested at a higher external static pressure than the old SEER rating, so identical equipment reads a lower number now. Manufacture of residential R-410A ended on January 1, 2025, and new ducted systems ship with R-454B. Condenser and coil replacement generally runs $5,000 to $9,000, while a typical residential installation lands between $7,500 and $10,000, averaging around $8,000. Duct condition, electrical, and the condensate path all move that figure. Estimates on a new or replacement system are always free.
