In corroborating their theory that a modern electric heat pump could replace the oversized system, the homeowner utilized data collected from smart thermostats. They discovered that their heating needs amounted to a fraction of the furnace’s capabilities, leading them to deduce that they only required a 2-ton heat pump—essentially the same as their air conditioning needs.
Utilizing tools like block load calculations can also help homeowners better understand their heating requirements. These calculations take into account various factors like insulation and thermal properties of building materials, providing a more accurate measurement of the necessary HVAC capacity.
