Preventative Maintenance

Hills Air provide air conditioning servicing which goes beyond the expectations, as not just the main plants are serviced. We ensure that the diffusers and air intakes are cleaned, ducts are clean, ask those in the area being conditioned if they have any issues, or comments to report. On completion of each air conditioner service, reports are completed, and we shall communicate with those that manage the buildings or the facilities manager. Should we find an issue we endeavour to rectify this as soon as we have approval for the extra work required.

Planned Maintenance Programs

Hills Air provide preventative planned maintenance agreement service programs (PPMAS). We ensure all systems have regular servicing to suit the application or climate it is located in. Commercial air conditioning maintenance ensures all the services comply with the manufacturer’s specifications and ensure the equipment is kept in good order to prevent unexpected cost, fatigue, and down time.

Quality Residential Air Conditioning Maintenance

Hills Air provides a wide range of air conditioning maintenance and breakdown services for all types of home heating and cooling systems. We recommend that your residential ac unit and heating equipment be checked and maintained twice a year.


We also recommend having a preventative maintenance service in the spring before you start using and in the height of summer and in autumn before the fall of winter. Much better to catch a problem before it becomes an expensive breakdown during a heatwave in summer or a freeze in winter.


On a maintenance service, we ensure your air conditioning system is operating to 100%. Following is a general list of requirements we recommend to keep your system in its most effective order to operate saving you operation cost.

General requirements recommended to keep your system in effective order to save operation cost

FILTERS

Ensure filters are clean, installed correctly in the filter frame, and that it isn't broken down - letting unfiltered air pass into your system.

CONDENSATE DRAINS

It is critical drains are flushed and tested to ensure water is draining away, as these can block up and cause flooding.

ELECTRICAL

Ensure all electrical connections are tight to prevent fires and shorting out to your system, causing damage to other parts.

ZONING

Ensure your zone damper actuators are opening and closing correctly, and that zone ordering is correct.

DUCTING

Ensure that the ducting is all connected and not leaking air into the ceiling cavity.

REFRIGERATION SYSTEM

Ensure that the cooling system has the correct refrigerant level, and that all valve caps are fitted and not leaking.
