Sometimes even on Saturday’s we have to get our customers out of a tough spot. A 20 year old unit decided to finally quit on this homeowner. A elderly couple with respiratory issues, our guys knew they needed to step up, without even asking several of our employees voluntarily asked to help this customer get up and running as fast as possible.

Appreciate all the hardworking from our staff and am pleased our customers were only without air conditioning for a few hours!
