Preventative Maintenance Programmes

At Thermachill, we believe that proactive maintenance is the most cost-effective approach to climate system management. Our tailored maintenance programmes are designed to prevent breakdowns, optimise performance and maximise energy efficiency.

Each maintenance programme includes:

Comprehensive system inspection and performance testing
Cleaning of critical components including condensers and evaporators
Refrigerant leak detection and system pressure checks
Control system calibration and operational verification
Filter replacement and air quality assessment
Detailed condition reporting with recommendations

We offer flexible maintenance frequencies tailored to your system requirements, from quarterly visits for critical equipment to annual inspections for less demanding applications. All maintenance is performed to manufacturer specifications, ensuring warranty compliance and optimal system performance.

Specialist Repair Services

When system faults occur, our specialist repair service delivers swift, effective solutions to minimise disruption to your business. Our comprehensive repair capabilities include:

Advanced diagnostic services using electronic fault-finding equipment
Compressor replacement and refrigeration circuit repairs
Electronic control system troubleshooting and repair
Fan motor and bearing replacement
Heat exchanger leak detection and repair
Refrigerant recovery, system evacuation and recharging

Our engineers carry extensive spare parts and diagnostic equipment, enabling first-visit resolution for most common faults. For more complex issues, we work efficiently to source specialist components and implement permanent solutions with minimal system downtime.

System Health Checks and Performance Optimisation

For businesses without regular maintenance contracts, we offer comprehensive system health checks to assess equipment condition and identify potential issues before they lead to failures.

Our health check service includes:

Visual inspection of all system components
Performance measurement against manufacturer specifications
Energy efficiency assessment
Refrigerant level and condition checks
Control system function testing
Detailed report with recommendations for optimisation

Following inspection, we provide clear recommendations for performance improvements, efficiency enhancements and preventative maintenance requirements, helping you make informed decisions about your climate systems.

FAQs

How frequently should commercial climate systems be maintained?

Maintenance frequency depends on system type, usage and criticality. Generally, we recommend quarterly maintenance for commercial refrigeration systems, bi-annual servicing for air conditioning systems (pre-summer and pre-winter), and annual inspection for less frequently used equipment. F-Gas regulations also mandate specific leak detection frequencies based on system refrigerant charge, which we incorporate into maintenance schedules.

What are the benefits of a preventative maintenance contract?

Preventative maintenance contracts deliver multiple benefits: reduced breakdown frequency (typically 60-80% fewer failures), extended equipment lifespan, lower energy consumption through optimised operation, priority status for emergency repairs, preferential labour rates, simplified budgeting with fixed maintenance costs, and comprehensive documentation for compliance purposes. Most clients experience a return on investment within 12-18 months through reduced repair costs and energy savings.

What warning signs indicate potential system failure?

Warning signs to watch for include: unusual noises (grinding, squealing or rattling), reduced cooling or heating performance, inconsistent temperatures, excessive cycling, increased energy consumption, ice formation on components, water leakage, and unusual odours. Early intervention when these symptoms appear can prevent minor issues developing into major failures and minimise repair costs.

Do you maintain systems installed by other companies?

Yes, we maintain and repair systems installed by other companies. Our engineers are trained across all major manufacturers' equipment including Daikin, Fujitsu, Mitsubishi Electric, Panasonic, J&E Hall, Kyong Dyong, Copeland and Danfoss. We begin with a thorough system assessment to understand the installation before developing an appropriate maintenance programme. We can often improve performance of systems installed by others through proper optimisation and component upgrades.

What environmental practices do you follow during maintenance and repairs?

Our environmental practices include: proper refrigerant management with specialised recovery equipment to prevent atmospheric release, responsible disposal of waste materials through certified recycling schemes, use of electric service vehicles for reduced emissions, optimisation of systems for energy efficiency, and recommendations for environmentally friendly refrigerant alternatives where appropriate. All our procedures comply with F-Gas regulations and environmental best practices.
