Tulsa Weather and HVAC Load
Tulsa logs 3,451 heating degree days and 2,128 cooling degree days in a normal year, based on the closest NOAA weather station. Neither season dominates in Tulsa. That balance is a big reason heat pumps and dual-fuel systems sell well in Oklahoma. On average, Tulsa gets 72 freezing nights and 74 days above 90°F per year. Snowfall averages about 9 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 45,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Tulsa Housing Stock
The median Tulsa home dates to 1972, according to the Census ACS. That makes the typical house about 54 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 52% of occupied homes, roughly 89,000 households. Homes here have a median value of $189,600 and households a median income of $58,407. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Tulsa County show 46 hail days and 46 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Tulsa County also had 6 tornado days in that period.

Oklahoma Permits, Efficiency Rules and Rebates
Oklahoma is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Expect the contractor to pull a mechanical permit for a replacement job in Tulsa. If a bidder suggests skipping it, move on. Also ask for a Oklahoma license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
