🔌

Surge Protection — Gauteng Essential

Gauteng's load-shedding and grid voltage spikes are the leading cause of inverter PCB and compressor failures. Ask your technician about surge protection installation on every repair — it protects your investment.

Know Your System

Common AC Faults & Aircon Sizing Guide — Gauteng

Recognising your AC's symptoms early prevents costly damage. The guide below covers the most common HVAC faults across Gauteng — and the standard BTU sizing reference for when a replacement becomes the better option.

🔍 Common AC Faults — What They Mean

Gauteng's climate and power grid create specific HVAC failure patterns. These are the faults our technicians repair most frequently across the province.

🌡️

AC Not Cooling / Warm Air

Usually indicates a refrigerant leak, low gas levels, dirty coil, or compressor failure. Do not keep running — switch off and call immediately.

💧

Water Leaking from Indoor Unit

Blocked drain line, faulty drain pump, or frozen coil thawing. Can cause ceiling and wall damage — turn off the unit and call for same-day repair.

AC Tripping the DB Board

Electrical fault — typically a failed capacitor, contactor, or wiring fault. Very common in Gauteng due to voltage spikes during load-shedding cycles.

❄️

Ice Forming on the Unit

Indicates low refrigerant levels, dirty air filter, or restricted airflow. Switch the AC to fan-only mode and call for a refrigerant check.

🔊

Strange Noises (Rattling, Grinding)

Loose components, failing fan motor bearings, or compressor damage. Noises worsen over time — early repair is always cheaper than delayed repair.

💨

Weak or Reduced Airflow

Blocked filter, dirty evaporator coil, or failing fan motor. Regular servicing prevents this — book a maintenance visit before the Gauteng summer peak.

📐 Aircon Size Reference — Gauteng Properties

If your AC system is beyond economical repair, this sizing guide helps you choose the right replacement. As a rule of thumb: if repair costs exceed 50% of the replacement cost, a new system is the better long-term investment.

Room SizeBTU RequiredTypical Use
12 to 18 m²9,000 BTUGuest Room, Study, Small Bedroom
19 to 25 m²12,000 BTUStandard Bedroom, Lounge, Office

Our technicians are factory-certified on all leading residential and commercial HVAC systems, ensuring expert-level repairs for both common and complex faults.

Gauteng's load-shedding cycles create two types of damage to AC systems. First, voltage spikes occur when power is restored — these can instantly destroy inverter PCBs and compressor electronics. Second, frequent on-off cycling stresses capacitors and contactors far beyond their design limits. KFRCOOL strongly recommends surge protection on all inverter AC systems in Gauteng, and we offer surge protection installation as an add-on to every electrical or compressor repair. It is the most cost-effective investment you can make to protect your AC system.

Yes. KFRCOOL provides priority commercial HVAC repair for all business types across Gauteng — offices, retail spaces, restaurants, hotels, shopping centres, warehouses and industrial facilities. We repair commercial VRF systems, cassette units, ducted systems, rooftop HVAC units, and central AC with emergency response typically within 30 minutes. After-hours installation and repair is available to minimise business disruption. We also offer tailored commercial maintenance contracts.

Call KFRCOOL immediately on 078 298 4438. Switch the AC off at the wall — do not keep running a unit that isn't cooling as this can worsen compressor damage and significantly increase repair costs. Note any error codes displayed on the remote or indoor unit. Do not attempt DIY repairs, as this can void warranties and create electrical safety hazards. Our Gauteng technician will arrive within 30 minutes and handle everything safely and correctly.

Refrigerant leaks in Gauteng are caused by corrosion of copper refrigerant pipes, vibration damage from loose components or poor installation, wear on connection joints and seals, physical damage to refrigerant lines, and age-related deterioration. Signs of a refrigerant leak include reduced cooling capacity, ice forming on the indoor unit or pipes, hissing or bubbling sounds, and rising electricity bills. KFRCOOL uses UV dye and electronic leak detectors to accurately locate leaks and provides permanent repairs with proper refrigerant recharge to manufacturer specifications.

Yes. KFRCOOL offers annual and bi-annual HVAC maintenance contracts for Gauteng homes, lifestyle estates, and commercial properties. Regular preventive servicing extends your system's lifespan, improves energy efficiency by up to 40%, and prevents costly emergency breakdowns. Contract benefits include priority emergency call-out, filter cleaning, coil wash, refrigerant level checks, electrical testing, and discounted repair rates for all contract clients.
