Redland City Council has spent $150,000 to replace air conditioning at the Donald Simpson Community Centre.
Mayor Karen Williams said the project reinforced council's commitment to the community facility.
"The Donald Simpson Community Centre has thousands of members and is one of the largest social hubs on Redlands Coast," she said.
"This project will ensure local and visiting seniors can socialise and enjoy the activities on offer in the comfort of a newly air conditioned centre.
"This project is on top of the maintenance of approximately $49,000 and other support provided annually to the Donald Simpson Community Centre.
"Council is committed to supporting the great work they do in our community and this project is creating a comfortable environment during both hot and cold weather and goes a long way to ensuring members continue to engage in the centre's vast range of programs."
Centre manager Thomas Jithin said the air conditioning replacement was appreciated.
"The centre is in use six days a week, from 8am to 5pm, and a couple of nights 'till 9pm and also hosts some great shows like annual orchid and bonsai shows, and other expos.
"The Donald Simpson Centre appreciates council replacing the previous older unit which was under performing for the room size," Mr Jithin said.
The centre opened in 1987 and was named after former Redland Shire clerk Donald Simpson, who served the city from 1963 to 1978.
In 2017 council had a falling out with the centre after councillors decided to end annual operational funding of $100,000 a year but to maintain maintenance works up to $60,000 a year and a notional rent of $100,000 a year.
Councillors said the $100,000 saved would be distributed more equitably to the needy.
Over 30 years, the centre received more than $1 million in funding for infrastructure and services while demand had increased from other sectors, like those with disabilities.
