I always run my furnace for about six months straight, and my house becomes extremely dry inside the winter. The forced air heat pulls most of the moisture from the air and creates insufficient humidity levels. This results in a whole bunch of problems and health problems. The dry air actually feels much colder as opposed to properly moisturized air, which always causes me to adjust the thermostat. Higher thermostat settings puts a more substantial workload onto the furnace. The furnace runs longer, uses more electricity, costs more to operate and even wears out faster. Plus, the dry air is bad for home furnishings, causing wood to dry out quickly and crack. Since I do have hardwood floors and moldings, and whole bunch of priceless antiques in my household, I hope to avoid these kinds of damages. I’ve also noticed that dried out air causes my skin to itch and forces me to constantly need to apply skin moisturizer. My hair gets frizzy, my lips chapped, and I get too many headaches. I’ve also read that when the air is overly dried out, people become more susceptible to getting sick. When I was growing very tired of the issues with the dry air, I contacted a local HVAC technician and invested in an actual humidifier. The humidifier didn’t cost as much as I expected. It was installed directly into the HVAC unit, and allows me to regulate moisture levels within my humble home. It operates silently, needs very little maintenance, and has definitely paid for itself. The furnace no longer needs to work as hard, and my house is now very comfortable. I certainly feel warmer, healthier and happier. I no longer get a shock every time I walk on the carpet. I’ve been able to lower the thermostat setting because of the humidifier which saves me a lot of money.
