Project Overview

P C Kelly Plumbing, Heating & Air Conditioning was appointed to provide a comprehensive Planned Preventative Maintenance (PPM) programme for a portfolio of commercial air conditioning systems across multiple business premises.

The customer operated a range of office spaces, production facilities and staff welfare areas that relied heavily on air conditioning to maintain comfortable working conditions throughout the year. With increasing demands on the systems, the client wanted to reduce the risk of unexpected breakdowns, improve energy efficiency and ensure ongoing compliance with F-Gas regulations.

Our experienced air conditioning engineers developed a tailored maintenance programme covering routine servicing, performance inspections, refrigerant checks and reactive support where required.

The result is a reliable, energy-efficient HVAC system that provides year-round comfort while reducing operational costs and extending the lifespan of valuable equipment.

Customer Requirements

The client required a specialist HVAC contractor capable of maintaining multiple commercial air conditioning systems under one planned maintenance agreement.

Their objectives included:

• Annual and bi-annual servicing. 
• Reduced equipment downtime. 
• Improved energy efficiency. 
• Compliance with F-Gas legislation. 
• Extended equipment lifespan. 
• Fast reactive support. 
• Comprehensive service reports. 
• One trusted maintenance contractor. 

The customer also wanted detailed records of every service visit to assist with compliance and asset management.

Our Solution

Following detailed surveys of each site, P C Kelly created a bespoke Planned Preventative Maintenance programme tailored to the customer's equipment and operational requirements.

Each air conditioning system was logged within our maintenance schedule, allowing servicing to be planned before peak summer demand.

Every visit includes a comprehensive inspection of system performance, cleaning of critical components and testing of refrigerant circuits to identify any developing faults before they become major breakdowns.

Any defects identified during servicing are reported with recommendations, allowing repairs to be planned before they affect business operations.

Scope Of Works

The maintenance programme includes:

• Air conditioning servicing. 
• Indoor unit cleaning. 
• Outdoor condenser inspections. 
• Filter cleaning. 
• Evaporator inspections. 
• Condenser coil cleaning. 
• Refrigerant pressure checks. 
• Refrigerant leak inspections. 
• Electrical inspections. 
• Drainage inspections. 
• Fan motor testing. 
• Temperature performance testing. 
• Operational testing. 
• Service reporting. 
• Reactive breakdown support. 

All servicing is completed by our directly employed REFCOM-accredited, F-Gas certified engineers.

Installation / Delivery Details

Air Conditioning Servicing

Each system undergoes a comprehensive service to maximise efficiency and reliability.

Typical servicing includes:

• Cleaning air filters. 
• Cleaning evaporator coils. 
• Cleaning condenser coils. 
• Inspecting fan motors. 
• Inspecting electrical components. 
• Refrigerant pressure checks. 
• Condensate drain cleaning. 
• Operational testing. 

Routine servicing significantly improves system performance while helping reduce energy consumption.

F-Gas Compliance

Where applicable, systems are inspected in accordance with current F-Gas Regulations.

Checks include:

• Refrigerant leak inspections. 
• Visual inspections. 
• Refrigerant charge verification. 
• Pipework inspections. 
• Record updates. 
• Compliance reporting. 

Maintaining compliance helps protect both the customer and the environment while ensuring systems continue to operate safely.

Improving Energy Efficiency

Dirty filters and poorly maintained equipment can dramatically increase running costs.

Our maintenance programme helps customers achieve:

• Lower electricity consumption. 
• Improved cooling performance. 
• Better heating performance. 
• Improved indoor air quality. 
• Reduced system wear. 
• Lower operating costs. 

Routine servicing ensures every system continues to perform as efficiently as possible throughout its lifespan.

Project Challenges

Multiple Locations

The customer operated several commercial premises requiring coordinated maintenance throughout the year.

Maintenance visits were carefully scheduled to minimise disruption while ensuring every system remained fully operational.

Preventing Summer Breakdowns

The majority of air conditioning failures occur during periods of high demand.

By servicing systems before the summer season, our engineers significantly reduced the likelihood of costly breakdowns during the busiest months.

Maintaining Business Operations

Many systems served occupied offices and production facilities.

Our engineers completed servicing with minimal disruption, allowing businesses to continue operating normally throughout maintenance visits.

Testing & Commissioning

Following each service, every system underwent operational testing.

This included:

• Cooling performance. 
• Heating performance. 
• Temperature measurement. 
• Airflow checks. 
• Refrigerant pressure verification. 
• Electrical safety checks. 
• Drainage inspections. 
• Final operational assessment. 

The customer received a detailed service report outlining the condition of every system together with recommendations for future maintenance or repairs.

Health & Safety

Health and safety is integral to every maintenance visit.

P C Kelly prepares:

• Risk Assessments. 
• Method Statements. 
• F-Gas compliance procedures. 
• Working at height procedures where required. 
• Site-specific safety documentation. 

All servicing is completed in accordance with current industry regulations and manufacturer recommendations.

Project Outcome

The Planned Preventative Maintenance programme has significantly improved the reliability and performance of the customer's air conditioning systems.

The customer now benefits from:

• Fewer unexpected breakdowns. 
• Improved energy efficiency. 
• Lower running costs. 
• Better indoor air quality. 
• Extended equipment lifespan. 
• F-Gas compliance. 
• Detailed maintenance records. 
• One trusted contractor for all HVAC servicing. 

The programme has enabled the customer to move from reactive maintenance to proactive asset management, reducing downtime while improving overall system performance.
