Planned Maintenance Contracts

A Reactive approach to Air-conditioning and refrigeration service and maintenance, such as repairing a system only when breakdowns occur, significantly increases through-life costs due to premature component failure and inefficient energy use.

Avoiding Service breakdowns is one major factor when regular maintenance visits are carried out. Industry experience evidence has proven that maintaining your equipment correctly has a massive impact on the life expectancy of systems.

With constantly increasing energy costs and the increasing impact on high energy usage on the planet a poorly maintained system will work harder and inevitably use more energy to run.

Your health has to be the most important thing whether at home at work out shopping or eating at a restaurant, where air-conditioning is installed and you are breathing the air around you. To prevent the spread of pathogens and bacteria it is highly important to keep your systems clean, filters free from heavy particle build up. If it’s just a single system at home or a business it is your responsibility to provide that people around you are in a safe healthy environment.

All maintenance work is carried out by our friendly, polite qualified service engineers. All visits are scheduled and booked in for an agreeable time and date and can be rescheduled if required at your instruction and we have various payment options to suit each customer individually. We run a 24 hour service existing customers benefit from a priority call out service.

What a Planned Maintenance Contract Includes

Your planned maintenance contract will be tailored to suit your particular installation. The frequency of visits will be discussed to ensure the optimum reliability and efficiency of your air-conditioning.

On each visit we carry out the following processes:

  • Check and clean condenser and evaporator coils
  • Check and clean evaporator filters
  • Check fan blades, fan motors and compressor
  • Check all electrical connections and cables
  • Check fuses, electrical isolators and protection devices
  • Check Condensate Pumps
  • Check and flush condensate drain, descale and water treatment
  • Check air ducts, grilles, filters and insulation
  • Check refrigerant pipework for damage and insulation integrity
  • Check Refrigerant temperatures and pressures
  • Check expansion devices
  • Check supply air temperatures
  • Check unit operation in all modes, controls and settings
  • Ensure units are clean and damage free
  • File a Schedule of all system details
  • Report any faults/submit a quotation for repairs
  • Leak check

Consumable items are included in the maintenance costs such as anti bacterial coil cleaners, cleaning materials, nitrogen and drain cleaning tablets. If you would like to discuss a planned maintenance contract or would like a one-off maintenance visit, please don’t hesitate to give us a call.

R22 Phase Out

R22 – A hydroflourocarbon (HCFC). R22 is a member of a class of compounds which have been linked to ozone depletion in the earth’s upper atmosphere. As a result, HCFCs ceased being used in new air conditioning equipment in the UK in 2003, in favour of non-ozone-depleting alternatives such as R410a and R407c. As from 1 January 2010, the use of virgin R22 and other HCFCs in the repair and maintenance of air conditioning and other refrigeration equipment was banned. To complicate matters further, the regulations also outlaw the stockpiling of virgin R22 for use after the deadline, so any R22 left unused at the end of 2009 should have been returned for destruction at the owner’s expense. New legislation is already in force for the removal and replacement of this low temperature refrigerant. A ban on the production of the refrigerant came into effect from the 1st January 2010. R22 refrigerant was widely used throughout in new air conditioning and industrial refrigerant plants and these changes in legislation affect any company that has a high requirement for R22 refrigeration; over 65% of the UK’s systems are assumed to still be running on R22. The refrigerant is still available in a reclaimed format until December 2014 however, demand is high due to the recent phase out and prices are expected if not already rising to extreme levels.

Options available to you:

1. Do nothing

Regulations do not prohibit the use of R22 equipment even after the December 2014 deadline and understandably if the system is operating satisfactorily, there is no urgent need to replace an existing installation. However, depending on how crucial the system(s) are to your business, the risk of failure is increasing as the years go by and even now spare parts are increasingly difficult to source mostly parts are obsolete. The risk with this strategy is however that at some point in the very near future the system operator/owner will be forced to choose between options 2, 3 or 4. It is therefore one of our objectives in assisting our clients both existing and new helping with a long term planning structure with our detailed advice and guidance with energy efficiency key to sustainability.

2. Recycled R22 (unavailable after 31 December 2014)

Use of recycled R22, seems to provide an easy way of extending the life of existing installations. However, a recent study by the British Refrigeration Association identified that a volume equivalent to just 10% of the amount of virgin R22 currently being used in the UK, is being returned for recycling. Due to its limited availability, recycled R22 is currently around 3 times the cost of virgin R22.Therefore, unless the situation improves radically, its poor availability and high cost means that a policy of relying on recycled R22 when the need arises is unlikely to be wise.

3. Drop in alternative

R22 can be replaced with a few alternatives and Premiair have actively been testing some of our current systems with R417a (splits) and R422D (VRF / VRV). This can only be considered a short term fix since as mentioned parts will be difficult to source and an end user may end paying for initially replacing the refrigerant short term with the inevitable full replacement that in the long term costs more money than a planned replacement over several years. Issues can also relate to the energy performance of the system with higher running costs, the pressure rating of compressors, condensers and associated pipe work, leak containment, lubricant compatibility and potential conflicts with manufacturer warranties will all need to be considered.

For owners of ageing R22 air conditioning equipment with a limited usefullife remaining, these complications can be overwhelming

4. Replacement of equipment

Replacement of the old R22-based air conditioning equipment with a new ozone-friendly system. At first sight, this seems to be the most expensive solution. However there are a number of factors which make this alternative increasingly the option of choice for owners, operators and maintenance contractors alike. The first reason is that as any R22-based air conditioning system is at least 6 years old and likely, therefore, to be driven by obsolete fixed-speed compressor technology. Its replacement with a modern, digital inverter-controlled system will bring significant immediate energy savings of up to 50%.

The cost and time spent replacing out-dated equipment can be reduced in some cases by retaining existing pipe work and electrical supplies. Many equipment manufacturers have introduced condensers and fan coil units specifically designed for this purpose, which can greatly simplify the installation and reduce disruption to building finishes and the activities of the occupiers.

Assuming the pipe work is replaced or found to be in good condition, a new installation will offer improved resistance to refrigerant leaks, ensuring owners can more easily satisfy their obligations under the European Fluorinated Gases (FGas) Regulations. These regulations require annual inspections to be carried out by qualified personnel, ensuring refrigerant systems are free of leaks and in full working order. A new system is also far less likely to suffer a breakdown and the associated costs of downtime and repairs, and will commonly come with the added benefit of a manufacturer-backed 3, 5 year warranty; in some cases 7 years with Premiair. A little-known further benefit is that, as almost all modern air conditioning systems incorporate heat pump technology as standard, the same system that provides comfort cooling in the summer can provide clean, highly energy-efficient heating in the winter.

This option of full system replacement is compelling but three more factors which make it even more convincing. Firstly, if the installation is in a domestic property, purchased by a charity or by a range of other not-for-profit institutions, the reduced VAT rate of 5% applies. Secondly, the Government’s commitments contained in the 1997 Kyoto Protocol came into force in February 2005. The aim of radically reducing the UK’s CO2 emissions has led to the introduction of the Enhanced Capital Allowance Scheme ( This Revenue & Customs-backed scheme allows any company replacing an existing air conditioning system with a more energy-efficient installation, to offset the entire cost of the project against its taxable profits in year the new system is installed. This effectively reduces the cost of the new system by an impressive 30%. It should also be remembered that a more energy-efficient system will enable building owners to achieve improved energy ratings under the recently-introduced Energy Performance of Buildings Directive. In addition, The Carbon Trust ( offers UK businesses of all types unsecured and interest-free loans. These loans, repayable over 4 years, are designed to fund their investment in a wide range of modern, energy efficient systems such as air conditioning.

For owner/operators who are concerned about meeting their responsibilities, Premiair can offer a wide range of technical expertise and commercial guidance with the foresight of planning towards a greener more efficient environment meeting your exact needs.
