Humidity plays a crucial role in maintaining the comfort in your home during the cold months. Make sure that the humidity levels remain in the 30-60% range. You don’t want the air to become dry because that will require the heater to work at higher temperatures for achieving the desired comfort level. This could also force the heating unit to work harder and increase the chances of heater repair services. On the other hand, make sure that water drops don’t form on the windows or other surfaces in your home because it is a sign that the air contains too much of humidity. If the humidifier is not working properly, get it checked by certified heating and cooling services.
