On a hot day, the last thing you need is a heat pump that can’t properly remove heat out of your house. Installing an incorrectly sized heat pump will force your system to work extra hard to meet your home’s comfort demands. Here are some signs that a heat pump is too big or small for a home in Barefoot Bay, FL:

High Energy Bills

You may see an increase in your energy bill after installing a new heat pump, yet utility rates remain the same. An inappropriately sized system is one of several HVAC concerns that can lead to a high energy cost.

A heat pump usually cycles on and off two to three times an hour. A system that’s too large may attempt to regulate temperature better than your home’s cooling and heating load requires. As a result, the system will give a quick burst of warm or cold air before shutting off.

The compressor of a heat pump uses a lot of energy when it first starts up. As a result, if the compressor starts and stops more frequently than it should, your energy costs will rise.

On the other hand, a smaller system won’t be able to meet your home’s heating and cooling needs. As a result, it’ll run indefinitely, attempting to attain the temperature you set on the thermostat. Continuous functioning raises your energy bill.


An overly large system heats and cools your house quickly and reaches the desired temperature before the whole cycle completes. This will cause the system to cycle on and off. Short-cycling can cause your HVAC system to wear out faster and lose efficiency.

Unequal Temperature Distribution

In the case of an undersized heat pump, the rooms closest to the system will be warmer during winter, while those further away will be colder. If you have an oversized system, failing to finish a temperature regulation cycle results in varying temperatures in different rooms in your home.

Repairs Are Required Regularly

As a larger-than-necessary system cycles on and off, it exerts a lot of strain on its components, causing wear and tear. As a result, you may need to call your service technician more frequently to maintain the system.

Investing in a heat pump that suits your house perfectly is the best approach to enhance energy efficiency. As a result, we begin each installation process by assessing your home’s temperature control requirements, taking into account the following:

  • Insulation.
  • Square footage.
  • Layout.
  • Load-generating appliances.
  • Doors, windows, walls and the roof.

Parts of a small heat pump also fail more frequently since the components are constantly in use. Certain components, such as the compressor, are too expensive to repair. Upgrading to a new system is recommended for increased comfort, efficiency and lower repair costs.

Humidity Issues

The evaporator coils of your heat pump collect excessive moisture from the air. The device then releases the moisture to the outside while allowing the dehumidified air to flow throughout your home.

High amounts of humidity in your house encourage biological growth. Biological growth emits spores into the air, affecting your indoor air quality. Your heat pump aids in the regulation of indoor temperatures as well as the removal of excess humidity.

A system must complete a temperature regulation cycle to eliminate excess humidity. Since it shuts down too quickly, an excessively large heat pump cannot eliminate the extra moisture in your house.
