This type of environment produces harmful airborne particles and gases, so effective extraction directly at source is essential for both safety and air quality.

Project Overview

This installation was carried out within a teaching workshop environment, requiring a clean, robust and highly effective solution.

The system includes:

• Twin wall-mounted extraction arms positioned over each workstation
• Rigid galvanised ductwork, neatly routed at high level
• High-quality capture hoods to extract fumes directly at source
• System designed for consistent airflow across both stations
• Clean, symmetrical install to suit an educational setting
• Explosion-Proof Extraction Fan

A key requirement of this project was the inclusion of an explosion-proof extraction fan.

Welding and brazing processes can introduce flammable gases and fine particulates into the air. Installing an explosion-proof fan ensures:

• Reduced risk of ignition within the system
• Compliance with higher safety standards
• Safe operation in a workshop training environment

The Finished Result

The completed system now provides:

• Effective removal of fumes directly from the source
• Improved air quality throughout the workshop
• A safer environment for both students and staff
• A professional, durable setup suitable for daily use

What Climate was called out to investigate poor-performing air conditioning units in Basildon at the Ministry of Hair Academy.

The system consisted of 4 x 7kW Samsung CAC 360 Cassette Unit systems, which were no longer delivering effective cooling or heating across the space.

Staff had noticed the environment becoming uncomfortable, with reduced airflow and inconsistent temperatures — clear signs the systems required attention.

The Issue: Reduced Cooling & Airflow

On inspection, it was clear the units were suffering from reduced performance due to lack of servicing.

Common issues identified included:

• Blocked or dirty filters restricting airflow
• Build-up on internal components affecting efficiency
• Reduced cooling and heating output across all four units
• Systems working harder than necessary to maintain temperature

Over time, this kind of build-up can significantly impact performance and increase running costs.

Our Air Conditioning Service

We carried out a full professional air conditioning service in Basildon, focusing on restoring system performance.

The service included:

• Deep cleaning of filters and internal components
• Inspection and cleaning of coils
• Checking airflow and overall system operation
• Electrical and performance checks
• Ensuring each unit was operating efficiently

Each unit was carefully serviced to bring it back to optimal working condition.

The Result: Strong Cooling Performance Restored

Following the service, the difference was immediate:

• Cooling performance fully restored
• Heating performance fully restored
• Strong, consistent airflow across all areas
• Stable and comfortable temperatures
• Improved efficiency and reduced strain on the systems

The academy now benefits from a much more comfortable environment for both staff and students.

Air Conditioning Servicing in Basildon

This project highlights how important regular maintenance is. Even high-quality systems like Samsung cassette units will lose performance over time without proper servicing.

At What Climate, we provide air conditioning servicing in Basildon and across Essex, helping businesses keep their systems running efficiently and reliably.

We work with:

• Salons and academies
• Offices and commercial spaces
• Retail environments
• Multi-unit systems

What Climate attended a same-day air conditioning call-out in Colchester to the No. Twenty Four Beauty & Skin Care salon.

The client reported that their Panasonic compact cassette air conditioning unit had stopped working and was displaying an error code, affecting comfort levels within the salon.

The Fault: H99 Error Code

Upon arrival, our engineer identified the system fault as:

H99 – Indoor Unit Freeze Prevention Protection

This error typically indicates that the system has detected conditions that could lead to freezing within the indoor unit, triggering a protective shutdown.

Left unresolved, this can result in:

• Loss of cooling or heating
• Reduced system performance
• Potential long-term damage if ignored

Diagnosis & Testing

A full diagnostic was carried out to identify the root cause of the issue, including:

• Testing the indoor pipe temperature sensor values
• Checking the indoor PCB (printed circuit board)
• Assessing overall system operation and conditions

All components tested within expected parameters, indicating no failed parts.

The Solution

With no component faults found, the system was:

• Safely reset
• Re-tested to confirm normal operation
• Monitored to ensure the fault did not return

The unit returned to full working order without the need for replacement parts.

The Result

• System fully operational again
• Cooling restored quickly
• No unnecessary parts or costs
• Customer very happy with the outcome

This was a great example of how accurate fault diagnosis can save time and money.

What Climate recently completed a commercial air conditioning installation in Harwich for the Harwich Haven Authority, delivering a high-performance cooling solution for a critical communications room.

This project demonstrates our expertise in server room cooling, data centre air conditioning, and commercial HVAC systems in Harwich and across Essex.

Project Overview – Server Room Cooling Harwich

• Location: Harwich
• Client: Harwich Haven Authority
• System Installed: Mitsubishi Electric PCA-M140KA3 (14kW)
• Application: Communications / Server Room

We were pleased to install the best in class Mitsubishi Electric LGH Lossnay ducted heat recovery ventilation units that have the option of being centrally controlled, or fully automated by the additional co2 traffic light sensor that communicates directly with the Lossnay unit itself as it senses when air quality levels dip below a set point.

A heat recovery system works by supplying fresh air and removing stale air simultaneously while retaining up to 81% of heat energy for ultimate efficiency. Other benefits include consistent air changes, giving a constant supply of fresh air, enabling staff to stay alert, and taking on tasks without the mental fatigue stale air can create.

For the air conditioning, it was an easy decision to stick with Mitsubishi Electric and the MSZ-AY / MSZ-AP R32 systems with a built-in WiFi interface enabling the end user full control over each unit by downloading the Mitsubishi Electric MEL cloud app onto a smart device.

All units both cool and heat, and for added security and peace of mind we installed protective security cages to help prevent vandalism and theft

We designed and installed a Mitsubishi Electric Lossnay heat recovery system. Each room needed both extract and supply air grilles that sit flush within the ceiling, making it visually appealing installation.

As with every ventilation project, our trained engineers fully balance and commission each rooms air volumes depending on size and traffic.
