Rooms need to meet a temperature of 68 degrees at all times and system has given alerts indicating temperatures reaching 70-71 degrees. Currently the system outputting cooling to those rooms is a 2005 unit and contains r22 Freon. The temperature split is 21 degrees and refrigerant pressures are within range. Recommendations are to speak to our new equipment consultant as more supplemental cooling might be needed to maintain a low temperature within those rooms. A heat load calculation can be done to see how much more cooling is needed to accomplish temperature needs. System is cooling upon departure.
