We assess honestly with you: is replacement the right economic decision now? We calculate the cost of keeping the old unit (repeated repairs + high electricity consumption) against the cost of a new unit — and guide you based on the numbers.
Old unit at EER 2.5 vs modern unit at EER 4.0: in Khamis Mushait running 2,000 hours annually (hot summer), the electricity bill difference can reach SAR 2,000–4,000 per year — meaning the new unit pays for itself in 2–4 years.
When Does Replacement Make Sense?
- Unit is over 12–15 years old
- Compressor has failed and replacement cost exceeds 60% of a new unit price
- Unit uses R22 refrigerant (old, scarce, expensive)
- Recurring repairs cost more than SAR 1,500 per year
- Unit fails to cool adequately despite repeated repairs
Upgrading to Inverter AC — The Smarter Investment
An old fixed-speed compressor (On/Off) runs at full power or not at all — like a light switch with no dimmer. An inverter compressor works like a dimmer — adjusting output precisely to what the room needs at each moment.
Why Inverter Matters Especially in Abha
Abha needs cooling in summer and heating in winter, and in both cases the load fluctuates throughout the day. An inverter adapts to this variability with efficiency a fixed compressor cannot match. An inverter AC in Abha consumes 30–45% less electricity than a conventional equivalent.
Correct Inverter Capacity Calculation for the Region
Upgrading to inverter is an opportunity to correct a possible original sizing error. We recalculate the thermal load properly, accounting for: Abha's altitude (10%+ correction factor), Jazan's humidity (additional dehumidification capacity requirement), and Khamis Mushait's peak heat load. The result may be a different capacity than the unit being replaced.
Full System Redesign
Sometimes an upgrade reveals other problems — inefficient old ductwork, or unbalanced air distribution. When installing a new unit into an old system, we assess the complete installation and provide a comprehensive recommendation: is replacing only the AC sufficient, or does the system benefit from partial ductwork upgrade as well?
Upgrading to R32 Technology
Old R22 units used an ozone-depleting refrigerant that has been phased out. R410A is far better, but R32 is the next generation — 5–10% more thermally efficient with lower atmospheric impact. When replacing an old R22 or R410A unit, we flag this advanced option.
A 2-ton conventional AC consumes ~2.4 kWh/hour. An equivalent inverter consumes ~1.6 kWh at average load. Difference: 0.8 kWh × 16 hours/day × 120 summer days × SAR 0.18/kWh = ~SAR 276 saved per summer. In 3–4 seasons the new unit fully pays for itself through electricity savings alone.
