Installation workflow — how GossTech does new AC installations
- Site survey & load calculation — We measure the room, occupancy, sun exposure and insulation, and calculate required BTUs (Cooling capacity). This prevents oversizing or undersizing.
- Unit selection advice — We recommend split, multi-split, inverter or ducted systems based on needs and budget.
- Electrical readiness check — Verify power supply capacity, earthing and MCB requirements; advise on upgrades if needed.
- Professional installation — Mount indoor and outdoor units, run copper lines, insulation, vacuum, pressure test, charge refrigerant, slope drainage and secure outdoor mounting.
- Testing & commissioning — Run system to confirm pressures, temperatures, current draw and airflow meet specifications. Provide user handover and operation tips.
- Warranty & service plan — Offer maintenance plans to keep manufacturer warranty valid and system efficient.
Maintenance & service plans (recommended)
| Plan | Frequency | What’s included |
|---|---|---|
| Basic Servicing | Every 6 months | Filter cleaning, basic coil wipe, drain check, performance test |
| Standard Maintenance | Every 4 months | Full indoor coil clean, condenser clean, blower check, refrigerant status check, electrical safety check |
| Premium Care Plan | Quarterly + priority calls | Everything in Standard plus annual chemical coil wash, UV treatment options, priority emergency response, discounts on parts |
Regular servicing preserves efficiency and prevents expensive failures — especially important in Nairobi’s climate.

Energy efficiency & upgrade recommendations
- Inverter ACs: Recommend inverter models for large rooms or offices for energy savings.
- Correct sizing: Oversized units short-cycle; undersized units run continuously. We always size properly.
- Smart controls & timers: Add programmable thermostats or smart plugs to reduce runtime.
- Regular maintenance: Dirty coils or blocked drains increase energy consumption — schedule regular servicing.
- Insulation & shading: Improve room insulation, blinds and reflective films to reduce cooling load.
FAQs (quick answers)
Q: How often should I service my AC?
A: At least twice a year (pre-hot season and post-hot season). Heavy use or dusty environments: every 3–4 months.
Q: Is refrigerant top-up a permanent fix?
A: No — refrigerant is sealed. A top-up without repair typically indicates a leak; GossTech finds and fixes the leak then recharges.
Q: Do you install split and ducted systems?
A: Yes — we install, service and repair split, multi-split, cassette and ducted systems.
Q: Can you service older brands/models?
A: Yes — we service very old and very new units. We advise when replacement is more cost-effective.
