We maintain wall-mounted and ceiling-cassette split ACs from leading brands—Daikin, Gree, Carrier, Mitsubishi—performing comprehensive coil cleaning, filter replacement, and refrigerant-charge optimization. Each service includes chemical disinfection of evaporator coils, fan-motor lubrication, TXV calibration, and airflow testing. Technicians verify superheat/subcooling readings, adjust refrigerant levels, and run performance tests under simulated load. Clients receive a service certificate detailing all actions, measured improvements, and next-service recommendations—ensuring sustained comfort in Lahore’s climate.

AC Fix Lahore’s certified team handles large-scale VRF/VRV networks and chillers up to 500 TR capacity. Services encompass oil-analysis and replacement, refrigerant balancing across multiple indoor units, microchannel-coil deep cleaning, and expansion-valve array calibration. We perform tube-bundle cleaning for shell-and-tube condensers, cooling-tower biocide treatments, and PLC-firmware updates on central controllers. Detailed thermal-imaging and vibration-analysis reports verify component health—ensuring reliable operation for hotels, malls, and data centers.

Our mobile service vans deploy 24/7 across Lahore, each carrying recovery machines, spare compressors, filter-driers, and diagnostic tools. Emergency repairs—compressor rebuilds, refrigerant leak sealing, control-board swaps—are executed on-site to restore cooling rapidly. Vehicles are GPS-tracked, with live ETAs sent via SMS. If immediate repair isn’t possible, we install temporary cooling units at no additional cost, ensuring critical processes and occupant comfort remain uninterrupted.

Our preventive-maintenance agreements cover scheduled inspections: refrigerant-leak tests, pressure-drop measurements, filter and belt replacements, safety-valve verification, and electrical-connection torque checks. Each inspection yields a compliance report aligned with Pakistan’s safety regulations, helping clients maintain warranties and insurance requirements. Detailed logs track system health metrics year-over-year, enabling predictive maintenance planning and budgeting.

We deep-clean duct networks using rotary brushes and negative-pressure vacuums, eliminating accumulated dust, mold, and microbial contaminants. Post-cleaning, we apply EPA-approved antimicrobial coatings and install UV-C sterilization lamps in air-handling units. Our IAQ assessments employ calibrated sensors to measure particulates (PM₂.₅/PM₁₀), VOCs, and CO₂. Based on results, we recommend HEPA or activated-carbon filtration upgrades, humidification controls, and regular maintenance schedules—ensuring healthier indoor environments for homes, schools, and offices.

For aging AC installations, we offer retrofits to boost efficiency and lower operating costs. Services include converting fixed-speed compressors to inverter-driven models, installing economizer controls for free-cooling, and integrating BMS connectivity via BACnet or Modbus. We upgrade heat-exchanger surfaces—replacing finned coils with microchannel units—and add variable-speed drives on fans and pumps. Each retrofit is supported by energy-savings projections under Lahore’s electricity tariffs and payback analyses—often achieving full ROI within two years.
