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.

Electricity Savings Calculation — The Region

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 range from about SAR 2,000 to SAR 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 costing more than roughly 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.

Return on Investment Calculation — Khamis Mushait

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.

Frequently Asked Questions

Do you remove the old unit?
Yes — we dismantle and remove the old unit. If it is in reasonable condition, it can sometimes be sold and the value deducted from the new unit cost.
Can the old unit's bracket be reused for the new one?
Sometimes yes — depends on size and type. We inspect it before installation to confirm it is safe.
What warranty comes with the new unit?
Manufacturer warranty (typically 3–5 years on the compressor) plus our installation warranty for one year.
When does replacing beat repairing?
A useful rule of thumb: multiply the unit's age in years by the repair cost. If the result exceeds the price of a new unit, replace. In practice: any unit past ten years that needs a new compressor is a clear replacement candidate.
Will a new unit actually cut my bill?
Yes, and noticeably so in a region where ACs run long hours. Inverter technology varies compressor speed rather than constantly cycling on and off, which cuts consumption especially on long runs — exactly the usage pattern of a Khamis Mushait summer.
Can I keep the existing copper pipework?
Sometimes, but not always. The lines must be flushed and inspected, and if the old compressor burned out, acids will have contaminated them — reusing them will kill the new compressor. Modern refrigerants also run at higher pressures that older pipework may not suit.
What happens to the old unit?
We dismantle it and recover the refrigerant properly — venting it to atmosphere is environmentally harmful and not permitted. We then take the old unit away.
How do you size the new unit?
We don't simply match the old one — the old one may have been the wrong size to begin with. We calculate from room area, ceiling height, insulation, window orientation and occupancy. Abha's cooler climate may need a smaller unit than Khamis Mushait for the same floor area.
Should I replace both units or just the outdoor one?
Both, in most cases. The two are designed as a matched pair; pairing a new outdoor unit with an old indoor coil means lower efficiency than advertised, refrigerant compatibility problems, and usually a void manufacturer warranty.
