Living in a bushfire prone area with an evap is a huge risk.
Found these guys online and put a query in through their website. Received a reply the same day and had screens installed 5 days later.
Great service, high quality product at a very reasonable price.

Approximate cost: $650

I have these ember guards installed on my evaporative cooler two years ago. They work well and look good. Clarence at Ash Screens was a pleasure to deal with and all correspondence was prompt.

Ember screens are very important and Ash Screens make a very good product. Cant recommend them more.

Approximate cost: $700

As the fire season was fast approaching I decided I really needed to do something about a cover for our evaporative airconditioner. After doing lots of searching, I found the website for Ash Screens, and was delighted to find they were local, as well as appreciating the range of information on the website.
I contacted Ash for a quote via the website and received a very speedy response. A couple of follow up emails were also quickly responded to, and the screens were measured up and installed within two weeks of my order, which I thought was really great considering that lots of other people are probably wanting them fitted before summer really kicks off.
Great service and a very useful product which will help with peace of mind!
