AC and Refrigeration Service in Lebanon: Installation, Maintenance, and Gas
AdvisorLB Team
From split units in apartments to chillers in offices, AC and refrigeration is one of the most common service categories in Lebanon. A clean, well-charged system uses less electricity — which matters when you're partially on generator.
Installation basics
- BTU sizing should be based on room area, sun exposure, ceiling height, and insulation — not just floor space.
- Copper line lengths should be kept as short as practical; longer runs lose efficiency.
- Outdoor units need airflow and shade. A unit baking against a south wall will struggle in July.
Maintenance schedule
- Clean indoor filters monthly during peak summer.
- Professional service yearly — coil cleaning, drain check, gas pressure, electrical inspection.
- If cooling drops, don't just add gas; ask the technician to find the leak first.
Gas types
Most modern units use R32 or R410A; older units use R22, which is being phased out globally. If your old unit needs a major repair, replacing with R32 is often more economical long term.
Choosing a contractor
- Ask for a written quote that separates unit, installation, accessories, and gas.
- Ask about warranty — and what voids it (lack of annual maintenance is a common exclusion).
- For commercial spaces, request a maintenance contract with quarterly visits.
