After being a stay-at-home mom for two years, my friend and I opened a daycare. We installed the best HVAC unit that the HVAC company could offer to help with indoor comfort. Given that we were to cater to kids between six months and one year, we also installed an air purification system because we didn’t want babies struggling with respiratory diseases while their moms were away working. We enlisted for home service with the HVAC technician from the local business to ensure we kept up with the HVAC maintenance schedule, significantly changing the air filter for improved air quality. All was well until the kids started showing symptoms of allergies. Unfortunately, one baby already had adenoids, and the mom withdrew him from daycare to avoid worsening the condition because he was struggling. That’s when we decided to close the daycare for a while until we solved the issue for the welfare of all the babies. The first thing we did was call the HVAC professional to assess all our air quality systems to see if the issue was somewhere within. We also called the local contractor who’d been in charge of the renovations in our daycare center when we renovated it to fit our needs, and he agreed that it could be a potential issue with the air in the rooms or something in our garden. Everything was inspected, with even a botanical florist coming to check on all the plants we had blooming; they let our triggering pollen into our sunroom area. The assessments revealed that we had accumulated dirt in the ductwork, which could be resolved with professional duct cleaning. Once the clean-up was complete, we reopened the daycare, and it’s been easy for all of us since.
