In past years, we would have two humidifiers working all winter long.
They would both be in the living room, and it would barely keep the humidity levels above forty.
This year, we went from using a humidifier to wishing we had a dehumidifier. The humidity was so high that I could feel the moisture on my face. I asked my husband what was going on, and why it was so humid, and he said he thought we had a vapor lock. I thought he was crazy. I had never heard of a house that got vapor locked. He said it usually kept the humidity out of the house, but something must have gone wrong. The vapor barrier was used to keep the humidity levels low in the summer, but it shouldn’t be working this way in the winter. We were now worried there could be mold throughout the house with this happening. I called the HVAC company the next morning and told them about the excess humidity in the house. He came over that afternoon and started looking for the problem. He said he couldn’t find anything wrong with the HvAC system, but if it persisted, he would need to look at something else. He then said it was a longshot, but he was wondering if there wasn’t a problem with the ductwork. He called the ductwork cleaners and told them we needed to have our ductwork cleaned before he did any further research on the humidity problem.
