Hello, we lived in another house for 10 years, no problems. we just moved to this older house that was recently remodeled about a year ago. during the day, we are fine. but at night, we're always coughing, our noses are stuffy and we get sore throats. i had a mold company come out, and they told me we didn't have mold. I change the AC filters constantly. i have NO IDEA how to even go about finding out what is causing this, but i can't sleep and neither can my husband or son. We are always getting sick, my son has bronchitis for the 4th time this year and my voice is getting weak from getting a sore throat every night. i also don't want to keep wasting money so i want to figure out what the problem is, but i don't know where to start. i thought of maybe buying an air purifier? i'm am at a loss as to what this could be. the house has beautiful Brazilian cherry floors and i keep it very clean. i also thought about replacing the air ducts. I am in Miami. Any ideas? i have no idea what else to do?
thanks for any guidance,
Carlos Alberto
