What to do if your heat pump is undersized?
The fix: Unfortunately, if your heat pump system is undersized, the best solution is to replace it with a system that is the correct size. Before installing your heat pump, a technician should have performed a load calculation, which would have determined the correct size heat pump you need for your home. However, sometimes technicians cut corners or simply make mistakes, which is how you could have ended up with a heat pump that is too small for your home.
Why Do Heat Pumps Run All the Time?
During cold days—the days when the temperature is below 30 degrees especially—your heat pump will run all of the time. In a standard furnace heating system, the unit consumes fuel, be it gas or electricity, and then pushes a large volume of hot air into your home and disperses it evenly.
How efficient is a heat pump?
A heat pump, however, is designed to run slowly and steadily, and to provide more consistent heat.

The Mechanics of the Heat Pump
Your heat pump works by taking refrigerant gas and compressing it. When this gas is compressed, it heats up.
The Disadvantages
Now that we know the advantages, let’s take a look at some of the disadvantages of a heat pump.
Cold Climates
With the heat pump becoming less efficient when temperatures are consistently below 30 to 40 degrees F, the U.S.’s northern states are not the best place to install a heat pump.
