Air Conditioning Maintenance

With our tailored maintenance programmes and rapid response in the event of an emergency you can rest assured that you and your air conditioning are in safe hands.
Routine preventative maintenance

Regular maintenance of your air conditioning system will save you money in the long run, minimising the likelihood of breakdowns and ensuring efficient operation.

All of our new installations are offered with a comprehensive preventative maintenance programme to ensure that your equipment is working optimally, reducing energy costs, repair bills and prolonging equipment life.

Manufacturers will only honour warranties on air conditioning systems that are regularly maintained, so a suitable maintenance programme is essential. Additionally, we offer routine and one-off maintenance programmes for existing air conditioning equipment already installed at your premises.

Statutory refrigerant leak testing

In line with the latest F-Gas regulations, most systems of a relatively small size must be leak tested at least once a year. The legislation lays down strict requirements for record keeping which must be kept for at least 5 years.

As members of Refcom Elite, you can be sure that we operate to the very highest standards of refrigerant management. Our company and engineers are F-Gas certified. Let us manage all of your F-Gas responsibilities for you as part of a planned routine maintenance programme to ensure you always comply.
