I'm guessing there's something I haven't checked. I've replaced the air filters and vents but everymorning I wake up when the heatings been on that night I have a sore throat and stuffed up nose. Any HVAC geniuses out there? Thanks.
Not sure where you live but I would suspect you are in a dry climate. I have forced air heating using natural gas but I live in a climate where the humidity is quite high. I believe you are experiencing these difficulties from the drying action in your nose and throat from the hot dry air being circulated by your forced air fan. I could only suggest the use of a humidifier to help relieve this condition. If you are not in a dry type of atmosphere you've got me. Have you had you furnace checked for a leak in the heat exchanger ( usually if the furnace is over 15 to 20 years old it has this potential. A leak in the heat exchanger can cause CO (carbon monoxide) to be blown into the rooms through the heating ducts. This could cause more serious problems but if your furnace is of that vintage you should get it checked, good hunting!
Sounds like you need a humidifier,also an electronic air cleaner.
