Why is my heat pump not keeping my house warm?
A clogged air filter
The first thing you should check when your heat pump begins to struggle with delivering warmth is the air filter for the HVAC cabinet. If the filter is clogged up with dust and lint because it hasn’t been changed in many months, it restricts how much air enters the heat pump to be heated.
