Mr Clancy, who regularly buys rags from the op shop for his business, Dave Clancy Electrical, saw a The North West Star article about elderly women volunteers at the op-shop working in the heat, last October, and decided to do something about it.

"I came down to the shop because my mate needed a suit for a ball we were going to, so we got him a $10 suit and some shoes and I just started chatting to Robyn, the manager, about what they needed," Mr Clancy said.

He said he saw "the girls" doing their good work and realised they needed some cool air - just his line of work.

The volunteers showed him the article and he took it away and laminated it for them.

True to his word, Mr Clancy installed the split system air conditioner in December, and it has given them relief over the hottest months, said manager Robyn Hammond.

"It's been so good for us and even cools down our little tin shed out the back where we have our morning tea," Ms Hammond said.

The facility manager for the Laura Johnson Home, Jan Hills, presented a plaque of appreciation to Mr Clancy at the op shop yesterday.

"The op shop is run totally by volunteers and the shop generates a steady income for the nursing home and has done for many years," Ms Hills said.

"Any assistance that we get from the community is always appreciated and it is this kind of gesture that is really appreciated by all the volunteers."
