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.

Louisiana Licensing and Efficiency Rules
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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Louisiana license or registration number before the visit.
Before You Hire
- Keep two feet clear around the outdoor unit, including snow.
- Book maintenance twice a year, once before summer and once before winter.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from Lafayette Homeowners
What does heat pump repair cost in Lafayette?
Most bills land between $180 and $890, including the service call. A typical visit is about $570. Night and weekend calls cost more.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
