Lafayette Weather and HVAC Load
Lafayette logs 1,574 heating degree days and 2,715 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. On average, Lafayette gets 18 freezing nights and 80 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.

Lafayette Housing Stock
The median Lafayette home dates to 1981, according to the Census ACS. That makes the typical house about 45 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 55% of occupied homes, roughly 29,000 households. The median home value is $251,300, and median household income is $61,454. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 14 days with damaging thunderstorm winds in Lafayette Parish. The largest hail reported was 1.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.
When It Makes Sense
- Your AC needs replacing, and you'd like cheaper heat at the same time
- The house heats with electric baseboard, oil or propane
- Energy bills are higher than you want them to be
What Moves the Price
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
- A ducted system or a ductless mini-split
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Size in tons, and whether the unit is cold-climate rated
We raised the national figures about 4% for Lafayette using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Commissioning and warranty registration

- Line set, drain and electrical hookups
Louisiana Permits, Efficiency Rules and Rebates
Louisiana 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 Lafayette; the contractor normally pulls it. Before you sign, ask each bidder for their Louisiana 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
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.
- Make sure the installer sized the system for your heating load, not only cooling.
- Ask your electric utility and state energy office what heat pump rebates are open right now.

Heat Pump Installation Questions from Lafayette Homeowners
How much is heat pump installation in Lafayette?
Plan on $5,700 to $14,100, with most jobs near $10,300. 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 Lafayette?
Between late fall and early spring. With 80 days over 90°F, Lafayette contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
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.
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.
