GUILFORD COUNTY, N.C. (WGHP) —  Crews are working to resolve heat issues at Rankin Elementary School in Greensboro. The school closed early on Tuesday and let students out at 11:30 a.m. because the heating system wasn't working properly. A spokesperson with Guilford County Schools said there was a technical issue in the control system of one of the units that led to mechanical issues. FOX8 caught up with the district’s only HVAC tech who was working all day on Tuesday at Penn Griffin School for the Arts to ensure the heating system was working properly. “Motors go bad. Bearings go bad. Bolts go bad. The igniters on gas packs. You never know what you're going to find when you get there,” GCS HVAC Tech 2 Joey Solomon said. Solomon is currently the only HVAC tech with GCS. Solomon was recently named GCS’s employee of the month. He works along with two assistants to address heat and air conditioning issues in the district. “There's always a problem somewhere. Predominantly, they keep me in High Point, and contractors do the rest of the county,” Solomon said. Solomon says he mainly works to fix HVAC issues at 23 schools while still getting around to the other schools in the district. The district has more than 100 schools, so they rely on contractors to help keep up with the demand. “Nothing runs forever or something breaks down every day,” Solomon said. Solomon listed some of the issues that are a top priority. “Burning smell, gas smell, water pouring out of a unit or ... especially kindergartens and mobile units ... Different emergencies, but I have tickets, and I try to go do the tickets. Unless I get an emergency call then I got to pack up and go do that one,” Solomon said. GCS when the coldest temps hit, its HVAC and boiler units can sometimes struggle to keep the buildings warm. Like RES where contractors are working to restore the heat. That school is 101 years old. “The newer stuff ... stays running for a good little while before it breaks ... The older stuff breaks down rather often then you fix it and hope for the best after that,” Solomon said. GCS says its HVAC employees and several contractors continue to prioritize and address heating issues as quickly as possible. In the meantime, GCS asks that parents send their students to school dressed for cooler temperatures or in layers that can be removed. If possible, the district will install portable heater units. Students may also be relocated to warmer spaces. If temperatures in more than 50% of a school fall below 60 degrees and HVAC repairs cannot be made within two hours, schools will be dismissed early or shift to remote learning.
