Maintenance Services

Air Technology Systems are specialists at reactive repairing, overhauling, and pro-active servicing and maintaining all types of HVAC systems.

Heating & Cooling

Our capabilities cover fully ducted systems with AHUs, incorporating electric or gas fired heaters as well as all types of standalone heating systems/units such as radiant heaters, unit heaters, fan heaters or those associated with air conditioning systems.

We are experts when it comes to resolving issues with HVAC Systems, including the provision of remote monitoring systems (RMS), which allow us to monitor your system remotely and spot any faults, or imminent failures to allow for an early resolution.

Cooling Only

We are experienced in dealing with AHUs that provide Industrial Cooling Solutions and incorporate DX / chilled water coils, condensers, and chillers. We have a very broad knowledge of Gas Fire Heat Pumps (GHPs) and, can also work on split air conditioning systems & VRF systems.

AHU Servicing

Air Handling Units typically treat and supply air to a ducted system. They are made up of various components, typically they may include:

  • Mixing box to allow mixing of fresh and room (recirculated air), with or without actuated control dampers
  • Filters
  • Fan(s)
  • Heating / cooling coils (DX, chilled water, electric or gas)
  • Instrumentation to allow monitoring and control
  • Local control panel

AHUs require regular servicing to keep them operating efficiently and safely. Problems can occur, for instance, when filters are not continually changed, or if a control instrument fails which will affect the correct running of the system.

We offer Planned Preventative Maintenance to all types of AHUs.

Ventilation

We offer PPM plans for fully ducted systems with AHUs, centrifugal and axial fans, filters, dampers, grilles, and louvres.

Industrial Ventilation systems are provided within buildings to provide sufficient fresh air for operatives or processes, or to keep buildings safe and comfortable (e.g., local exhaust ventilation systems, or general building extraction systems).

It is therefore important to keep them in a serviceable condition, to ensure your building is meeting the necessary requirements and to avoid unexpected breakdowns.

Our experience also covers the full Service & Maintenance of Odour Control Units (OCUs), as we have over 20 years experience in the industry.

Odour Control

Air Technology Systems have a vast experience in providing Odour Control systems and can issue maintenance, repairs, and media changes to:

  • Biofilters
    • We can make repairs to biofilters (e.g., blocked or poorly performing irrigation systems which are common without regular maintenance).
    • Media replacements – all types of organic and inorganic media (e.g., shells, bark chippings, lava rock etc)
  • Carbon filters
    • We can make repairs and replace all types of carbon filter and complete media replacements.
    • We offer all types of carbon non-impregnated and impregnated and can work with you to understand your needs

 

LEV

Air Technology Systems are experienced at reviewing and assessing all types of LEV and Odour Control Systems and can provide certification to show correct operation of the systems.

Often Odour Control Systems have a complexed design & control, and correct operation of the system should be checked regularly to ensure it is working correctly.

This is especially important for those which are linked to Local Exhaust Ventilation (LEV) systems – e.g., directly extracting from tanks, to comply with HSE Regulations where this a legal obligation to complete these checks at least every 48 months.

We can also visit a site to conduct surveys and assessments of existing operational and failed Odour Control plants to make recommendations to improve operations or bring them back into service.

Maintenance Compliance

When working with gas systems you can rest assured that Air Technology Systems engineers are fully trained and Gas Safe, and for refrigerant systems have the peace of mind that we are F Gas Registered.

F Gases are refrigerant gases such as HCFCs, HFCs and CFCs; they are used in refrigerated applications and equipment, including air conditioning.

REFCOM Standards

As regulated by REFCOM, all air conditioning and cooling installations that contain more than 2.14kg (5 Tonnes CO2) of an F gas refrigerant should be leak checked once a year. If the system contains more than 24kg (50 Tonnes CO2) of F gas refrigerant, then they should be check checked every 6 months, for leaks and damage, by a contractor certified to work with F gases.

Air Technology Systems can provide the necessary legal checks and certification as part of a servicing agreement, to ensure that your installation remains safe and compliant.

We issue a detailed report after every visit to inform you of the work completed and any further recommended works.

Call Outs

For reactive works and repairs we can typically attend site within 24 hours, and will quickly diagnose the problem, making recommendations to allow us to get your system back up and running as quickly as possible.

For planned servicing and maintenance visits, we will collaborate with you to understand your risks, busy operating periods to develop a pro-active maintenance schedule to support your business.

We can also provide one-off service visits, filter changes or other specific tasks to suit your needs and budgets.
