MESQUITE (CBSDFW.COM) – Some residents at a Mesquite apartment complex are hoping today is the day they will finally get some relief from the heat.  Since Thursday, dozens of residents at a Mesquite apartment complex have been living without air conditioning.  Despite assurances from the City of Mesquite and property managers that the units had been fixed, residents were still complaining about issues early Tuesday afternoon.

The temperature started rising some resident’s units after the chiller system at the Hillcrest Apartments broke. The problems couldn’t have come at a worse time, as temperatures start to creep near the triple-digits.

The A/C failure were a result of a massive leak in the chiller system at the complex, near the intersection of North Galloway Avenue and Hillcrest Street. However, days after the problem was discovered, repairs were still being made.

Officials with the City of Mesquite provided some relief — with fans, etc. They also set a deadlines for the complex, stating that if repairs were not completed before 4:00 p.m. on Tuesday, the city would begin relocating some residents. Those at the most risk would be given the highest priority.

There was at least one building at the Mesquite apartment complex that was still without air conditioning Tuesday morning, according to residents. But nearby, another building started to feel cool air again overnight.

As residents waited for repairs to be completed, they found their own ways to keep cool, leaving windows open at night and getting away from the apartment complex during the heat of the day. Regina Miller said, “Me and my son, we actually drove to south Dallas and ride around in the car to keep cool. I think we went to every 7-Eleven getting Slurpees.”

Miller said she hoped property managers understood the frustration of their tenants. “They sitting in the A/C right now,” she stated. “I wish they could just sit in an apartment like us for one night and see how it feels to experience what we going through, because they wouldn’t be able to do it.”
