The City of Union Municipal Building will be closed Friday while upgrades are made to its heating and air conditioning systems.

Mayor Harold Thompson said Wednesday that the city is using a grant to finance upgrades to the building’s heating, air conditioning and lighting.

“We’ve got some upgrades that need to be made to the heating and air conditioning systems,” Thompson said. “We received a $75,000 grant last year to upgrade to the heating and air conditioning systems and some lighting. The lighting work was done in-house and has been completed. On Friday, upgrades will be made to the heating and air conditioning systems.”

Thompson said the decision was made to close the municipal building while the upgrades are being made because of the heat.

“We decided to close the municipal building because the air conditioning system will be shut down while the upgrades are being made,” Thompson said. “Without the air conditioning, it will be pretty hot in the building and so we decided to shut it down until the upgrade is completed. The municipal building will reopen for business Monday morning as usual.”

Anyone who wants to pay their utility bill Friday may still do so by placing the bill and the payment in the drop box at the municipal building. Thompson added that if a customer prefers to pay their bill in person, they may wait until Monday to do as there will be no cut-offs of service Friday.
