Having a humidifier is a wonderful thing. I have my humidifier built right into my HVAC system. I used to have dry and annoyed skin, now that I have my humidifier my dry annoyed skin has gone away. The humidifier puts moisture into the air. winter time dries out the air so it is best to put some moisture back in the air. The moisture is what prevents the dry, itchy skin from happening. When my humidifier breaks down, I feel as if I break down as well. I start to worry about my dry itchy skin coming back. To prevent this from happening I try to get official maintenance on it. I get it looked at when I get my tune ups twice a year. I try to notice when two things happen; water leaks or not enough moisture. Both of these things can indicate that there may be a problem with my humidifier. If there is a water leak this can mean that the wick isn’t receiving enough water to be evaporated into the air. There could be too much pressure anywhere or a blockage. If there is not enough moisture in the air this could mean there also isn’t enough moisture getting to the system. A number of issues is related to this, however it could just be a plugged line. This system needs little maintenance however when I get my HVAC unit tune up, I make sure they also look at the humidifier. It is the best way to guarantee that I do not have to spend money for future repairs. An HVAC company is regularly a cellphone call away. I know that I can trust them to make sure all HVAC equipment runs effectively and efficiently.
