On a repair call in LaSalle Parish, a contractor starts with the compressor and the contactor, because those are the parts that have been cycling hardest. Homes in LaSalle Parish, LA run cooling about five months a year, from May through September. A compressor that starts and stops through a full cooling season accumulates wear on its capacitor, its contactor points, and its refrigerant seals at a rate that shows up in failure patterns a contractor can read from what they find when they open the unit. Condenser fan motors take the same outdoor heat exposure. A diagnosis that skips those components and goes straight to the air handler is skipping the parts most likely to have given out.
Parts availability is what decides the scope and the bill on many repairs in this parish. Half the homes in LaSalle Parish, Louisiana were built in 1983 or earlier (2020-2024 ACS 5-year). Housing stock that old has been through more than one generation of central AC, which means the system a contractor opens today is running in a house that was built for something else entirely. When a part is worn or failed, whether it is still manufactured, and what a contractor can source and when, shapes the repair more than the diagnosis does.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it holds the compressor and condenser coil. These are the parts a contractor reaches first when a system stops cooling, runs constantly, or makes noise it should not make. A failed compressor or a coil clogged with debris are common reasons a system stops doing its job.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil is a frequent source of trouble, whether from ice buildup, refrigerant loss, or dirt that accumulates over time. The blower moves conditioned air into the duct system, and a failing motor or a dirty wheel shows up as weak airflow throughout the house. The thermostat and the refrigerant lines connecting the two units round out what a contractor examines.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in LaSalle Parish
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
