Evaporative Air Conditioners

An Evaporative air conditioner that is regularly serviced and maintained will run better and last longer. A poorly maintained Evaporative air conditioner will be inefficient and be prone to breakdown. It could also be dirty and unhealthy.

Regular and ongoing maintenance also gives you the peace of mind of knowing that your Evaporative air conditioner can be relied upon and will constantly work at its optimum capacity.

To ensure your Evaporative air conditioner is running its best, and in many cases, to ensure you satisfy warranty conditions, manufacturers do advise that maintenance be carried out at least twice a year (Before Summer and at the end of Summer).

The cost of maintenance is it important to the life of the Evaporative air conditioner, not to mention the cleanliness and health of your home, but it also pays for itself by catching small defects before they have the opportunity to turn into major problems.
