An AC compressor in Prairieville was overheating, drawing approximately 30 amps, and shutting off on thermal overload. An inspection revealed a large ant mound and debris blocking part of the condenser coil. After cleaning, compressor amperage dropped to approximately 19–20 amps.An AC compressor in Prairieville was overheating, drawing approximately 30 amps, and shutting off on thermal overload.

A Prairieville homeowner had little airflow downstairs even though the air conditioner was operating. We diagnosed a failed Zone 1 damper and found a crushed return ductboard plate pulling hot attic air into the system.

An upstairs HVAC system in Geismar struggled with cooling, humidity, and weak airflow. We found closed registers, a closed duct damper, excessive discharge pressure, and a dirty condenser coil.

A Bard wall-mounted air conditioner at SA Recycling in Prairieville kept freezing overnight even after an initial coil cleaning and blower-control repair. A deeper cleaning of the thick three-row evaporator coil uncovered heavy internal buildup, while refrigerant testing also revealed the system had been significantly overcharged. This Prairieville HVAC case study shows why airflow must be verified before adding refrigerant to a frozen air-conditioning system.

A previous diagnosis pointed to a bad capacitor, but complete testing uncovered two different problems: a disconnected reversing-valve plug and a refrigerant leak. Here is how the Gonzales heat pump was repaired without replacing a capacitor that was still testing properly.

A five-ton Denham Springs AC was still operating, but several electrical issues were making the system work harder than it should. Here’s what we found with the weak capacitor, aging hard-start kit, and 30-amp fuses on equipment rated for up to 55 amps.

If your AC runs all afternoon but the indoor temperature keeps rising, learn the common causes, what you can check safely, and when to schedule HVAC service.
