Do Heat Pumps Work in a Real Winter?

Heat pumps don't make heat — they move it. So what happens at −25°C (−13°F)? In this video: how a heat pump really works in a cold winter, why some installations leave people cold, and the three questions that decide whether one makes sense for your home. ━━━━━━━━━━━━━━━━━━━━ WHAT YOU'LL LEARN • How a heat pump pulls heat out of freezing air • How efficiency drops as it gets colder — and how cold is too cold • The 4 ways a heat pump install goes wrong (including the sizing mistake) • Why "3× as efficient" doesn't mean "3× cheaper" • When dual-fuel (heat pump + furnace) is the sweet spot ━━━━━━━━━━━━━━━━━━━━ FREE CHECKLIST Run these checks on your own home — the bill test, the specs to demand, and the questions to ask every contractor: 👉 https://progradehomescience.com/heat-...
