Commercial Air Conditioning Installation
The right air conditioning system starts with understanding the building and what the system needs to achieve.
Before specifying equipment, factors such as the use of the building, occupancy, operating hours, areas requiring cooling, heating and cooling loads, existing infrastructure, controls, access and future maintenance requirements may all need to be considered.
PGS can design, specify and select air conditioning systems to meet the requirements of the project, or work to an existing consultant or client specification where one is already in place.
We can support:
- New air conditioning installations
- Replacement installations
- Extensions to existing air conditioning provision
- System upgrades
- Changes required following alterations to building use or layout
Where existing equipment is being replaced, we do not assume that a like-for-like replacement is automatically the right answer. Changes to the building, occupancy, operating requirements or the performance of the existing system may mean a different approach is more appropriate.
Once the system and specification have been agreed, our engineers can carry out the installation and commissioning.
We also understand that commercial air conditioning is frequently installed or replaced in operational buildings. Access, working hours, occupants, customers, tenants and other contractors may all need to be considered, so installation is planned with communication and disruption in mind.
Air Conditioning Servicing & Maintenance
Regular servicing helps maintain air conditioning performance, identify developing problems and reduce the risk of avoidable breakdowns.
The servicing required will depend on the equipment, how heavily it is used, its operating environment, manufacturer requirements and any applicable F-Gas obligations.
Depending on the system, servicing may include checks of:
- General equipment condition
- Filters
- Coils and heat exchangers
- Fans and airflow
- Condensate and drainage
- Controls and sensors
- Electrical components and connections
- Operating temperatures
- Refrigerant circuits where applicable
- Unusual noise, vibration or leakage
- Overall system operation and performance
Where F-Gas requirements apply, appropriately qualified engineers can undertake relevant refrigerant handling, leak checks and record keeping.
If servicing identifies a fault or deterioration, we can distinguish between work requiring more immediate attention and items that should be monitored or planned for the future.
PGS offers standalone air conditioning maintenance contracts, as well as the option to incorporate air conditioning into a wider PGS Planned Preventative Maintenance programme.
Commercial Air Conditioning Repairs & Fault Finding
When air conditioning isn’t performing properly, the symptom does not always tell you where the problem lies.
You may be experiencing:
- Air conditioning not cooling effectively
- Inconsistent temperatures
- Reduced airflow
- Unusual noises or vibration
- Water or condensate leakage
- Control or sensor faults
- Intermittent operation
- Equipment repeatedly cutting out
- Unexpected changes in system performance
- Complete system failure
Our engineers can investigate the system, identify the cause of the problem and advise on the appropriate repair.
Where faults require urgent attention, PGS also provides reactive 24/7 air conditioning call-out support.
The aim is to understand what has failed and why before recommending the next step. Where appropriate, this may also identify underlying maintenance issues or developing problems elsewhere in the system rather than simply addressing the immediate symptom.
Air Conditioning Replacement & Upgrades
An air conditioning fault does not automatically mean the system needs replacing. Equally, continuing to repair ageing or unreliable equipment is not always the most practical long-term option.
When assessing an existing system, we can consider factors including:
- Equipment age and condition
- Reliability
- Frequency and cost of repairs
- Current system performance
- Energy use
- Availability of replacement parts
- Obsolescence
- Refrigerant considerations
- Whether the equipment still meets the needs of the building
- Changes to occupancy or building use
Depending on what we find, the appropriate route may be repair, partial upgrade or replacement.
Where replacement is appropriate, we can assess the current requirements of the building rather than simply reproducing an installation that may have been designed many years earlier.
Air Conditioning Maintenance Contracts & PPM
For organisations responsible for commercial buildings, regular air conditioning maintenance can be easier to manage when it is planned rather than arranged only when something goes wrong.
PGS offers standalone air conditioning maintenance contracts for businesses that want scheduled support specifically for their air conditioning equipment.
Air conditioning can also be incorporated into a wider PGS Planned Preventative Maintenance (PPM) programme, alongside other supported building services.
A planned approach can help provide:
- Greater visibility of servicing requirements
- A developing maintenance history
- Earlier identification of recurring faults
- Better planning of remedial work
- Visibility of ageing or deteriorating equipment
- Improved coordination across multiple systems or sites
- Fewer unexpected maintenance requirements
- Better information for future repair and replacement decisions
For facilities managers, property managers and organisations responsible for multiple buildings or sites, this can provide a clearer picture of air conditioning requirements across the estate rather than managing each problem in isolation.
Free Air Conditioning Site Evaluation
If you have inherited air conditioning equipment, have limited service records or simply aren’t sure what condition your systems are in, knowing where to start can be difficult.
PGS offers a free initial Air Conditioning Site Evaluation to help establish that starting point.
Depending on your requirements, we can look at the equipment in place, discuss known faults or performance concerns, review available maintenance information and understand how the systems and building are currently being used.
From there, we can help identify practical priorities and whether servicing, repairs, further investigation or a planned maintenance programme should be considered.
This gives you a clearer starting point before deciding what, if anything, needs to happen next.
The free initial evaluation is not a detailed technical condition survey. Where more extensive investigation is required, we will explain this before any additional work is undertaken.
REFCOM F-Gas Certified Air Conditioning Support
PGS holds REFCOM company certification for relevant work on stationary refrigeration, air-conditioning and heat-pump equipment containing fluorinated greenhouse gases.
Our appropriately qualified engineers can undertake installation, repair, servicing, maintenance, leak checking, refrigerant recovery and decommissioning where the relevant F-Gas requirements apply.
Depending on the type and quantity of refrigerant within the equipment, operators may have statutory responsibilities relating to leak checks, repairs and record keeping. PGS can help identify the requirements relevant to the equipment we maintain and provide the appropriate service documentation.
PGS REFCOM Company Certification: REF1024497
TM44 Air Conditioning Inspections
Commercial air-conditioning systems in England and Wales with a combined effective rated output of more than 12kW must generally be inspected by an accredited air-conditioning energy assessor at intervals of no more than five years.
This can include multiple smaller air-conditioning units where they are under the control of one person and their combined effective rated output exceeds 12kW.
A TM44 inspection is separate from routine air-conditioning servicing, maintenance and F-Gas leak checks. It assesses the energy efficiency and sizing of the air-conditioning system and provides recommendations where improvements could be made.
PGS can help identify the air-conditioning equipment and installed capacity at your premises and establish whether a TM44 inspection may need to be considered. Where a statutory inspection is required, this must be carried out by an appropriately accredited air-conditioning energy assessor.
Air Conditioning for Commercial Buildings
Commercial air conditioning requirements vary considerably depending on how a building is used.
PGS supports air conditioning in commercial environments including:
- Offices
- Retail premises
- Hospitality
- Education
- Care environments
- Industrial premises
- Warehouses
- Commercial property
- Public sector premises
- Multi-site estates
An office occupied throughout the working day can have very different requirements from a warehouse, care environment, retail unit or building containing areas where temperature control is particularly important.
Occupancy, operating hours, internal heat loads, access, critical areas, maintenance windows and the consequences of equipment failure can all influence how air conditioning should be installed and maintained.
Our approach considers those operational requirements alongside the equipment itself.

Commercial Air Conditioning FAQs
Can you take over an air conditioning system installed or previously maintained by another contractor?
Yes. PGS can assess and maintain existing air conditioning equipment regardless of who originally installed or serviced it. Where service information is available, this can help us understand the system's history. Where records are limited, we can establish the current condition and maintenance requirements from the starting point we find.
How often should commercial air conditioning be serviced?
The appropriate servicing frequency depends on the type of equipment, how heavily it is used, its operating environment, manufacturer recommendations and any applicable F-Gas requirements. We can assess your equipment and help establish an appropriate maintenance schedule rather than applying the same servicing frequency to every system.
Can you maintain air conditioning across multiple sites?
Yes. We can support air conditioning across multiple buildings or locations. Understanding the equipment at each site allows servicing and maintenance to be planned around individual requirements while building a clearer maintenance history across the estate.
Do you offer air conditioning maintenance contracts?
Yes. PGS offers standalone air conditioning maintenance contracts. Air conditioning can also be incorporated into a wider PGS Planned Preventative Maintenance programme alongside other supported building services.
Do you provide 24/7 air conditioning call-out support?
Yes. PGS provides reactive 24/7 air conditioning call-out support when faults require urgent attention.
How do I know whether an air conditioning system should be repaired or replaced?
There is rarely a single deciding factor. Age, condition, reliability, repair history, system performance, parts availability, refrigerant considerations and whether the equipment still meets the requirements of the building can all influence the decision. We can assess the existing equipment and explain the available options.
Can you design and specify a new commercial air conditioning system?
Yes. PGS can design, specify and select air conditioning systems to meet the requirements of the project. We can also work to an existing consultant or client specification where one is already in place.
What if we don't know what air conditioning equipment we have?
That isn't unusual, particularly where equipment has been inherited with a building, installed at different times or previously managed by several contractors. Our free initial Air Conditioning Site Evaluation can help establish what is in place and provide a starting point for servicing, repairs or planned maintenance.
Can air conditioning servicing and installation be planned around our operating hours?
Yes. We regularly work in operational commercial buildings, so access, working hours, occupants and the potential for disruption can all be considered when planning the work. The appropriate arrangements will depend on the building and the work required, which can be discussed with you in advance.
Does my commercial air-conditioning system require a TM44 inspection?
In England and Wales, air-conditioning systems with a combined effective rated output of more than 12kW must generally be inspected by an accredited air-conditioning energy assessor at intervals of no more than five years. Multiple units under the control of one person can count as a single system when determining the combined output. The inspection is separate from routine servicing and F-Gas leak checks. PGS can help identify the equipment and installed capacity at your premises and advise whether a TM44 inspection may need to be considered.
Is PGS REFCOM F-Gas certified?
Yes. PGS is REFCOM F-Gas certified for relevant work on stationary refrigeration, air conditioning and heat pump equipment containing fluorinated greenhouse gases. Our REFCOM company certification number is REF1024497.
