Maintenance Proven To Save You Money

Costs of Running Your Air Conditioning Unit
Contamination of the condenser and evaporator coils can increase your system's energy consumption by as much as 36%.
Dirt buildup on the Air Conditioning coils will reduce your system efficiency. This will mean:
  • Bigger energy bills
  • Poor system performance
  • Short component life

Optimum Performance Levels

System Efficiency & Cleaning
Cleaning your Air Conditioning system will also destroy 99.9% of all bacteria and fungi on contact in under 60 seconds.
As well as making sure your unit is working when you need it, maintenance and system cleaning is also effective in eliminating many micro organisms including:
  • M.R.S.A
  • Legionella
  • E.coli

Air Conditioning Service & Maintenance

For your peace of mind we strongly recommend that your systems are subject to regular maintenance. It is a recognised fact that a regularly serviced air conditioning unit will have a far longer lifespan, higher performance and be more energy efficient than a unit which does not receive Planned Preventative Maintenance.

We are able to offer you a ‘tailor made’ Planned Preventative Maintenance contract to suit your needs which will ensure that your systems are always working at optimum performance levels.

The installation of your air conditioning system is a major investment.  Naturally you will want to protect your investment by prolonging the life of your system and ensuring that the air conditioning units are running efficiently and economically.   To achieve this we would suggest that you enter into a Maintenance Contract which will ensure regular servicing and will help achieve the longevity and efficiency of your system for many years.

It is our experience that the vast majority of expensive air conditioning repairs occur as a result of systems which have not been subject to any regular maintenance or servicing.  Typically when being used in a residential environment we would normally recommend two service visits per year, but for more critical use, e.g. server rooms, trading floors, retail shops and restaurants, we would normally advise that your air conditioning Maintenance Contract allows for more frequent service visits.

Look out for the following symptoms – they are the classic indicators of a poorly maintained air conditioning system:

  • Poor airflow
  • Stale odours
  • Loss of performance
  • Dirty appearance
  • Sludge in drain line
  • Increased energy bills
  • Prone to freezing
  • Leaking water
  • Nuisance High Pressure & Low Pressure alarms

Advice on Air Conditioning Service & Maintenance

There is no better time than the Spring to have your air conditioning system serviced in good time for the Summer months. Very often small problems spotted at the time of service stop them from becoming major and expensive problems later on. Here are some questions we are frequently asked: -

Q. Is there a suggested period for re-gassing my air conditioning system?

A. Using your air conditioning system does not use up the refrigerant gas inside it. In fact, if conditions were ideal it would never need re-gassing. During servicing and maintenance, the level of gas is checked and a low level means that in all likelihood there is a minute leak in the air con system. Most recently manufactured air conditioning units have connections which are welded to minimise leaks but older units used to have mechanically connected fittings which, over the years, can vibrate loose and cause a leak and the air conditioning system will fail.

The effects of a gas leak are as follows: -

  1. The efficiency of the air conditioner is reduced considerably.
  2. The refrigerant cools the compressor and over a period of time a low level of gas can cause the compressor to overheat and
    breakdown. This would require a complete replacement of the compressor and sometimes the condensing unit as well.
    These are both very expensive repairs.
  3. Low gas levels can also cause the evaporator coil to freeze up. When the air conditioning unit defrosts, it will normally restart and
    then freeze again.
  4. The refrigerant gas is a “controlled substance” in respect of environmental hazard. It therefore, must not be released into the
    atmosphere which is a process obviously happening if your system is leaking.
Q. Should I take my installer’s advice and arrange regular check ups for my air conditioning systems?

A. We do recommend at least annual air conditioning system checkups and these should be done in the Spring. By undertaking this programme of maintenance, you would minimise the risk of expensive repairs later on. Also, the main advantage is that your system should function efficiently during the Summer months.

Q. What actions are carried out to the air conditioning system during the service?


  1. Filters are checked and cleaned.
  2. The evaporator and condenser coils are cleaned.
  3. All motors are oiled where required.
  4. Check condenser.
  5. Check thermostat is working accurately.
  6. Check all electrical fittings and test controls.
  7. Check for correct refrigerant levels. If found to be low check and repair any leaks before adding further gas.
Q. What can I do to maintain my air conditioning unit?

A. Ensure that the condensing unit which is located outside of your premises is not covered up or blocked in any way. The efficient operation of your system depends on the condenser unit drawing air into the system so that it can be cooled and expelled inside. If the condenser is blocked in any way then it will not be able to pull through enough air from outside. An air conditioning unit needs to breath the same as humans do.
