-
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.
-
Do heat pumps work when it’s cold outside?
Yes, heat pumps even work when it’s cold outside, but the colder it is, the harder they work to do so. That means that as it gets colder, it becomes less energy-efficient. However, they’re ideal for Phoenix’s climate, where temperatures are rarely below freezing.
