Comprehensive Air Conditioner Services by GossTech
We offer end-to-end AC solutions — from brand-new installations to preventive maintenance and expert repairs. Here’s a breakdown of our core services:
🔧 Installation
- Site inspection & load calculation to determine the correct unit capacity (in BTU / Tonnage), based on room size, insulation, and intended use (bedroom, office, living room, commercial space).
- Correct placement of indoor and outdoor units — ensuring adequate clearance, structural support, and proper airflow.
- Proper electrical and wiring setup — includes installation of circuit breakers, surge protectors, earthing (grounding), and dedicated AC power lines if needed.
- Gas charging and leak testing — ensuring refrigerant is at manufacturer‑recommended levels with no leaks before commissioning the unit.
- Functional testing — verifying cooling performance, thermostat calibration, airflow, drainage, and remote / control panel functionality before handing over.
🧽 Servicing & Preventive Maintenance
Regular maintenance is essential to avoid breakdowns and prolong AC lifespan. Our maintenance service typically includes:
- Cleaning or replacing air filters.
- Cleaning indoor evaporator coils and outdoor condenser coils.
- Checking refrigerant levels and topping up if needed (subject to leak test).
- Inspecting and tightening electrical connections.
- Testing thermostat, controls, fans (indoor blower + outdoor condenser fan), and drainage system.
- Lubricating motors and checking compressor and other mechanical parts for wear.
- Cleaning the drainage pan and ensuring the condensate pipes are clear.
- Verifying cooling efficiency and airflow after maintenance — adjusting settings for optimal performance.
We recommend servicing at least twice a year (beginning and end of dry or hot seasons) — more often if the AC is used heavily or in dusty environments.
🛠️ Repair & Troubleshooting
When something goes wrong — noisy operation, no cooling, leaks, or power issues — GossTech technicians arrive with tools, diagnostic equipment, and a commitment to restore your AC to full working order. Below we list common AC problems and how we diagnose and fix them.
Common Air Conditioning Problems & How GossTech Diagnoses & Repairs Them
Below is a detailed table listing the most common issues AC owners face — along with what GossTech does to diagnose and fix each.
| № | Problem / Symptom | Diagnosis Approach | Repair / Solution by GossTech |
|---|---|---|---|
| 1 | AC running but not cooling (or low cooling efficiency) | Check for dirty/blocked filters, clogged evaporator or condenser coils, insufficient refrigerant, faulty compressor, restricted airflow, or improper thermostatic settings | Clean or replace filters; clean coils; check refrigerant levels and top up (or fix leak if found); test compressor function and replace compressor if faulty; correct thermostat settings; ensure proper airflow (fans working properly) |
| 2 | AC not powering on or not responding | Inspect power supply: circuit breaker, wiring, earthing; inspect remote and control panel; check internal safety switches | Reset/fix circuit breakers; repair or replace faulty wiring or earthing; fix or replace defected control panel or remote; ensure all safety switches are functional |
| 3 | Water leaking from indoor unit (or onto walls or floor) | Check drainage tray and pan, drain pipe for blockages; inspect condensation drip pan; inspect refrigerant line insulation; check for overflow due to misalignment | Clear blockages; realign or re-install drain pipe; clean or replace drainage pan; re‑insulate refrigerant lines if sweating; re‑mount indoor unit levelly if misaligned |
| 4 | Outdoor unit making loud / unusual noise | Inspect fan motor/blades, condenser fan, compressor mounting, vibration dampers, foreign objects (e.g. debris, sticks), loose bolts | Remove debris; tighten bolts; replace damaged fan blades; lubricate or replace fan motor; replace worn vibration dampers; secure compressor mountings |

| 15 | AC not cooling rooms uniformly (hot/cold spots) | Check airflow distribution, duct or vent blockage, improper unit sizing, faulty fan/airflow, refrigerant imbalance | Clean or clear vents/ducts; rebalance airflow; ensure unit size is correct for room capacity; repair blower or fan; perform refrigerant balancing and calibrate thermostat / dampers if installed |
How GossTech Diagnoses — and Why It Matters
When you call GossTech for a repair, our technicians follow a systematic diagnostic approach rather than guesswork. First, they conduct a full inspection — examining electrical wiring, refrigerant levels, airflow, filters, thermostat settings, and visible signs of damage or wear (e.g., oil stains, rust, water leaks, coil frost, noise, obstruction).
Next, where needed, they deploy specialized diagnostic tools such as:
- Refrigerant pressure gauges / leak detectors
- Clamp‑meters / multimeters (for electrical testing)
- Airflow meters or simple airflow inspection methods
- Refrigerant line temperature probes (to detect freezing or undercharge)
- Visual inspection / flashlight / moisture sensors (for leaks)
Based on findings, they provide you with a clear diagnosis and cost estimate — whether it’s a simple filter cleaning or a full compressor replacement. Only after your approval do they proceed with repairs or maintenance.
This thorough methodology ensures problems are addressed at the root cause — not just patched temporarily — saving you from repeated breakdowns and unnecessary costs.

Frequently Asked Questions (FAQ)
Q: How often should I service my air conditioner?
A: We recommend servicing your AC at least twice a year — ideally at the beginning and end of the hot season. If the unit is in heavy use or the environment is dusty (e.g., near dirt roads, Gatundu surroundings), servicing every 4–6 months is better.
Q: How long does a typical AC repair take?
A: Minor issues — like cleaning filters, clearing drainage, or topping up refrigerant — can often be completed in 1–2 hours. More complex jobs — such as compressor replacement or fixing refrigerant leaks — may take a half day to a full day, depending on parts availability and complexity.
Q: Do I need to buy spare parts myself?
A: No. GossTech carries common spare parts (filters, capacitors, fans, wiring, basic compressors) and can order brand-specific parts if they’re not in stock. We include the cost of parts and labor in our quote before beginning work.
Q: Can you service older AC units or do you only repair new ones?
A: Yes — we service and repair both new and older units. As long as the unit is repairable (i.e., not structurally damaged or irreversibly corroded), we can perform cleaning, leak detection, gas recharge (if allowed), electrical repair, and more.
Q: Does GossTech offer any guarantee on repairs?
A: Yes. We stand by our workmanship: for most small to medium repairs (fan motors, wiring, capacitor, gas top-up) we offer a 30-day workmanship guarantee. For major repairs (e.g., compressor replacement), we guarantee correct installation and testing — but compressor parts are covered by the manufacturer’s warranty (if applicable).
