What you can check yourself
Look at the outdoor unit first. If snow or ice has built up around the base or the coil is packed solid, clear it away so air can move through. Check the air filter inside, a clogged one chokes airflow and makes the whole system work harder than it should. Walk around the house and make sure no vents are blocked by furniture or closed off. Check the thermostat batteries and settings, a heat pump set to the wrong mode will blow air that feels cold even though nothing is broken.
