For your home
What this week’s weather means for heating, cooling, pipes and fresh air.
Heating this week
About 65% less heating than a typical week.
This week 61Typical 173
Heating degree days, base 65°F

47, 17 and 5°F are the test points heat pumps are rated at. About 31 hours are near freezing and damp, when outdoor units defrost more often.
Comfort
Dry air outside (dew point 25°F). Indoor air will run dry too — a humidifier keeping indoor relative humidity in the 30–50% range is more comfortable and cuts static shocks, without going so high it fogs cold windows.
Open the windows?
No stretch in the next few days is comfortable enough outside, by temperature, dew point and air quality.
Is this typical?
