How often should I change my air filters?
It depends on the filter and other factors, including whether you have pets in the home, smoke, leave windows open during the day, etc. Some filters will fill up within a month, while others may take three months. Because every home is different, we recommend checking your filters every month until you establish the ideal frequency for your home.

Can I use a heat pump to cool my home as well?
Yes, heat pumps can both heat and cool your home, making them ideal for year-round comfort.
