An “always on” fan often causes concern — but most often there is nothing wrong. In most cases, someone in your home has moved the fan switch to “On” instead of “Auto”. This cues your system to power the indoor fan continuously. Simply move the switch back to “Auto” and the fan should turn off after each cooling cycle.
While a heat pump is more than capable of effectively heating your home, the temperature of the air coming out of the registers is heated to about 90 to 95 degrees, depending on the outdoor temperature. This means the heat pump is heating your home by blowing air that is still below normal body temperature (98.6 degrees Fahrenheit). Because it’s nearly 10 degrees cooler than your internal temperature, your body’s thermometer perceives the air as being “cool”.
At the beginning of each heating and cooling season, it’s important to ensure your system is ready for the season. Spending a little twice a year can save you a lot in energy bills every month by keeping your system running at peak efficiency. You can also avoid expensive repairs by identifying and fixing minor problems before they turn into big ones. In addition, the manufacturer warranties for your units may be considered invalid if they aren’t serviced twice a year.
