Heat pumps are known for their impressive energy efficiency and have become increasingly popular among Rhode Island homeowners in recent years. But in order for a heat pump to operate at peak efficiency, it needs to be the right size for your home. If it’s too big or too small, it won’t be able to perform optimally and could end up wasting energy and costing you money. 

Why Does Heat Pump Size Matter? 

When we talk about heat pump sizing, we’re not referring to the physical measurements of the unit, but to its output, and how that output compares to the heating and cooling load of your home. 

If Your Heat Pump Is Too Big...

Heat pumps that are too big produce more energy than is necessary to heat and cool your home, which causes the heat pump to meet set temperatures quickly and then shut off soon after starting up in a process called short-cycling. Short-cycling puts added stress on your HVAC system and can cause excessive wear and tear and breakdowns. It also wastes energy and is likely to drive up your electricity costs. 

If Your Heat Pump Is Too Small...

Undersized heat pumps are no better. If your heat pump is too small, it won’t be able to keep up with your home’s heating and cooling demands, leading to inconsistent and uncomfortable temperatures throughout the house. Undersized HVAC units also waste energy, as they’ll run constantly as they try to meet a temperature they aren’t powerful enough to reach. 

How Is Heat Pump Size Calculated?  

In order to enjoy optimal efficiency, energy savings, and home comfort, your heat pump needs to be the right size for your home. Figuring out what size heat pump you need, however, can be tricky. There are a lot of factors that need to be considered, including the: 

  • Size of your home 
  • Location of your home 
  • Height of your ceilings 
  • Number, style, and position of your windows 
  • Amount and effectiveness of insulation in your home 
  • Amount of air infiltration your home experiences 
  • Number of people who live in your home and their temperature preferences

Sizing a heat pump or mini split involves a lot of complex calculations, and if you get it wrong, you could end up wasting a lot of money on equipment that doesn’t work the way you need it to. That’s why it’s best to turn to an HVAC professional for mini split heat pump sizing calculations.   

HVAC contractors perform size calculations all the time, and they have the tools needed to perform exact calculations quickly. A trusted contractor will also be able to answer any other questions you may have about HVAC sizing, like “what size HVAC ducts do I need?”
