A heat pump can both heat and cool a home, compared to an air conditioner which only provides cooling. In other words it's a replacement for both your air conditioner and your furnace or boiler. That means when you install a heat pump you're getting two major appliances for the price of one.

Common Causes of an Air Conditioner Blowing Warm or Hot Air These can be due to clogging issues, electrical problems, low refrigerant, evaporator coil malfunctions, or compressor problems. If you've ever had the ac system in your car stop functioning, it's often due to a refrigerant leak or dirty coil.

Forced air heating relies on a furnace or heat pump to distribute warm air through a network of ducts, while central heating uses a central heating unit, such as a boiler, to circulate heated water or air through pipes or ducts to radiators, baseboard heaters, or underfloor heating systems.

If your air conditioner won't blow hot air, there is a possibility that it is having trouble receiving power. It could be a bad breaker, faulty wiring, or an undersized breaker. You can start troubleshooting by looking for signs like corroding or fraying wires, burnt breakers, and more.
