This summer’s record-breaking temperatures are putting air conditioning systems to the test on construction equipment everywhere. Excessive heat contributes to operator fatigue, which can result in lost productivity and create potential hazards on the job site, so it’s important to make sure your heavy equipment’s air conditioning systems are in peak working order. A poorly performing air conditioning system puts additional load on the machine’s engine, which means higher fuel consumption. Even a slow freon leak affects cooling performance, and the loss of lubricant can lead to system contamination or premature air conditioner failure. A freon recharge, in the short run, will keep your construction equipment’s A/C going, but it will not solve the root cause of the problem.
