Visiting her grandma was the highlight of Alison’s Summer each year from when she was a baby. Even as an adult, she still kept the tradition whenever possible. She’d still plan to visit now despite running a really busy real estate firm in another city, and her grandma was regularly waiting for her with open arms during each visit. But, last year was the first time she wasn’t waiting outside waiting for Alison. When her granddaughter pulled up at the driveway, she got worried seeing the empty poach seat. After letting herself in, she found her Grandma in bed because she had an awful sore throat. The house was frosty because the A/C was turned up. Alison rushed to the control component to turn it down plus started tending to her grandma. It turns out that because it was in the middle of Summer, her Grandma wanted cooler air from the HVAC system. But, by increasing the output, she had put her health at risk. The cool air from the powerful A/C component had caused her to catch a cold and was responsible for the sore throat. Her Grandma was shocked that the unit could cause her to fall ill. Alison drove her grandma to the doctor plus explained what had happened with the cooling unit. The doctor recommended her Grandma to avoid cranking up the smart AC, especially at night. It was better to endure a little heat as opposed to having frequent infections. The heating plus A/C system was producing too much dry air that would continue to harm her health. Additionally, he insisted they get a heating plus A/C expert to check the component plus do usual service as a preventive measure. At times, dirt tapped in the air filter would contribute to sore throats. The best way to prevent this in the future was to have the filters cleaned respectfully.
