For your home

What this week’s weather means for heating, cooling, pipes and fresh air.

Drip faucets tonight

Tonight’s low: 15°−9°

Overnight low of 15°F for 8+ hours — cold enough that pipes in unheated spaces can freeze. Let faucets on exterior walls drip overnight.

Heating this week

About 72% less heating than a typical week.

47, 17 and 5°F are the test points heat pumps are rated at. About 8 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 24°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.
