Thanks for the responses, the units here are condos, four buildings with eight units each and one with four. Our CCRs state that the coolers are the owners responsibility. It is my belief that no owner should be allowed on the roof and that in order to service the coolers a licensed professional needs to be hired. I will call my insurance company and ask them.
Jared,
Based on my past experiences with evap coolers in Arizona, I would think that these are not a very good choice for a condo complex where the owners are expected to maintain their own coolers. These things take a lot of maintenance, with a minimum of installing new pads in the spring and preparing for winter in the fall. Thirty six owners climbing on the roofs twice a year creates a lot of potential disasters. You not only have the possibiltity of people falling off the roofs, but also dropping things from the roof, dropping things through the roof, and putting holes in the roof. If the owner does things wrong, you can end up with water running on the roof, under the roof, into the trusses, or down the ducts into the condo.
The best solution would be to encourage owners to replace the evaporative coolers with refrigeration-type air conditioning. Since that is a hard sell, your next best solution would be, as you suggested, to allow only licensed contractors to do the job. I would, however, take it one step forward and have the association hire a single contractor to bring all units up to snuff and keep the coolers maintained. I think you should be able to make a pretty good deal for regular monthly maintenance on 36 coolers. This means that the assessments go up to cover this new expense, but the deal you make ought to cost less than each owner hiring his own contractor.
When I first moved to Phoenix in the late 1960's, swamp coolers were in widespread use. Today, they tend to be relegated to older homes in less desireable areas. Evap coolers do not do a good job when the humidity goes up and the added moisture in the air does a fair amount of damage as it rots wood and rusts metal. The units themsevles will eventually rust out and water leaks from them can cause serious structural damage. As I mentioned above, there is a fair amount of maintenance during cooling season. By contrast, refrigeration keeps the home cool without the moisture and the units run forever with little maintenance. I have not had a swamp cooler in over 30 years and do not miss them a bit.
