Recent HVAC Jobs in Prairieville
A look at real HVAC work completed by Air Innovations in Prairieville, Louisiana.
TechPure Whole-House Air Cleaner Installation in Prairieville
Indoor Air Quality
Installed a new TechPure TT-MAC-2522 whole-house air cleaner at the indoor HVAC system in Prairieville. The air cleaner is fitted at the duct connection beside the air handler as part of an indoor air quality installation.
AC Compressor Overheating From Dirty Condenser Coil in Prairieville
HVAC Maintenance
Performed HVAC maintenance and system diagnostics after the air-conditioning compressor was overheating and shutting off on internal thermal overload. The compressor was initially drawing approximately 30 amps, exceeding its 23.7-amp rated load amperage. Inspection found a large ant mound, dirt, and debris accumulated inside the condenser and along the lower portion of the condensing coil, severely restricting heat transfer. Thoroughly cleaned the condensing coil and removed the ant mound and accumulated debris from inside the condenser. Allowed the compressor to cool, restarted the system, and checked operating pressures and amperage. After cleaning, compressor amperage decreased to approximately 19–20 amps, and the compressor was no longer overheating or shutting off on thermal overload. Verified the system was operating at the completion of service.
Failed Zone Damper Actuator and Damaged Return Ductboard in Prairieville
Duct Repair & Airflow
Responded to a complaint of poor airflow to the downstairs living area. Performed diagnostics on the zoning system and verified the zone control board was operating properly. Found the Honeywell power-close, spring-open Zone 1 damper actuator had failed, preventing the downstairs damper from opening correctly during a cooling call. Manually secured the damper in the open position to temporarily restore airflow and cooling until the actuator can be replaced. While inspecting the attic, found the ductboard plate above the return-air grille had been stepped on and crushed. The damaged return ductboard is allowing the system to pull unconditioned attic air into the return, reducing efficiency and increasing the cooling load. Verified refrigerant operation and found the system operating within an acceptable range at the time of testing.
Thermostat Fan Relay Wiring Repair in Prairieville
Thermostat Service
Customer reported that the air-conditioning system was running continuously and would not shut off. Performed diagnostic testing and found an issue with the thermostat fan-relay wiring that was keeping the blower energized. Corrected the wiring and verified that the system was cycling and operating properly. Checked the refrigerant operation after the repair and found the readings within the normal operating range. Also noticed that the outdoor condenser coil is dirty and should be cleaned to help maintain airflow, efficiency, and cooling performance. Recommended enrolling in the Single System Maintenance Plan.
Disconnected Kitchen Ducts Found at Stefano’s Authentic Italian
Duct Repair & Airflow
Inspected the attic ductwork at Stefano’s Authentic Italian near Highway 42 and Airline Highway. Found two 8-inch supply ducts disconnected from their ceiling grilles and discharging conditioned air into the attic. Provided an estimate to rework the duct system with four 8-inch drops serving the kitchen. Also found the freezer condenser rejecting heat into the attic and recommended venting it outdoors. No ductwork or venting corrections were completed during this visit.
Commercial AC Freeze-Up Repaired at SA Recycling
AC Repair
Responded to SA Recycling on Airline Highway after the system repeatedly froze up. Instead of recommending immediate replacement, corrected the underlying problems. Replaced the stamped return grille with a return filter grille, thoroughly cleaned the evaporator coil, blower, condenser coil, and drain pan, blew out the condensate drain, replaced the failed fan relay on the control board, and installed a new two-pole contactor.
AC Tune-Up, Capacitor Replacement, and Coil Cleaning
HVAC Maintenance
Performed an AC tune-up and diagnosed a failed run capacitor as the cause of the service call. Replaced the capacitor and cleaned the heavily soiled outdoor condenser coil to improve airflow and system operation.
Located Hidden Attic Filter Base for Easier Filter Changes
Duct Repair & Airflow
Investigated the customer’s difficult filter-access setup, which required removing a ceiling grille. Located the system’s existing filter base behind the attic furnace and showed the customer where the 20x25x5 filter is designed to be installed, eliminating the need to remove the ceiling grille for routine filter changes.
Smart Thermostat Installation and Blown Fuse Repair
Thermostat Service
Responded after a homeowner’s smart-thermostat installation caused the 3-amp fan-coil fuse to blow. Replaced the fuse and installed the new thermostat. Found the foil backing separated from an insulated access panel and secured it with spray adhesive. Also observed mold inside the fan coil, discussed a UV light as an option to help control growth, and straightened the 3/8-inch copper refrigerant line so it would not become buried in the ground.
High Humidity Diagnosis and Weak Capacitor Replacement
HVAC Maintenance
Investigated a complaint of excessive indoor humidity. Found a return-duct condition that may be drawing attic air into the system, with moisture and rust visible around the furnace and heat-exchanger area. Tested the 70/7.5 µF capacitor at 41/5.7 µF and replaced it. Operating amperage decreased after replacement. Provided repair options for the return-duct and humidity issue.
