Biloxi Weather and HVAC Load
Biloxi logs 1,457 heating degree days and 2,754 cooling degree days in a normal year, based on the closest NOAA weather station. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 11 nights at or below freezing and 52 days over 90°F.

Biloxi Housing Stock
The median Biloxi home dates to 1990, according to the Census ACS. That makes the typical house about 36 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Biloxi has roughly 9,600 owner-occupied homes, or 48.6% of households. Homes here have a median value of $203,200 and households a median income of $55,958. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 21 days with damaging thunderstorm winds in Harrison County. 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.
When It Makes Sense
- The house heats with electric baseboard, oil or propane
- Your AC needs replacing, and you'd like cheaper heat at the same time
- There's no natural gas service on your street
What Moves the Price
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- A ducted system or a ductless mini-split
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
- Size in tons, and whether the unit is cold-climate rated

What the Quote Should Cover
- Thermostat setup and backup heat settings
- Commissioning and warranty registration
- Line set, drain and electrical hookups
- The outdoor heat pump and an indoor air handler or coil
- A load calculation and equipment selection
Mississippi Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in Biloxi; the contractor normally pulls it. Before you sign, ask each bidder for their Mississippi 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.
Before You Hire
- Make sure the installer sized the system for your heating load, not only cooling.
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Ask your electric utility and state energy office what heat pump rebates are open right now.

Heat Pump Installation Questions from Biloxi Homeowners
How much is heat pump installation in Biloxi?
Plan on $5,500 to $13,500, with most jobs near $9,900. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Biloxi?
Between late fall and early spring. With 52 days over 90°F, Biloxi contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
