Gulfport Weather and HVAC Load
In a normal year, Gulfport racks up 1,507 heating and 2,748 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. On average, Gulfport gets 16 freezing nights and 69 days above 90°F per year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

The median Gulfport home dates to 1986, according to the Census ACS. That makes the typical house about 40 years old.

Homes here have a median value of $167,100 and households a median income of $46,044. Those two numbers drive the labor adjustment in our estimate.
Harrison County had 10 hail days and 21 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2 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. Harrison County also had 9 tornado days in that period.

Mississippi Licensing and Efficiency Rules
Mississippi 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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Mississippi the company should carry a state license or registration. Ask for both.
Before You Hire
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- If the furnace is past 15, ask the tech to price both a repair and a replacement.
- Ask whether the diagnostic fee comes off the repair bill.
