Why sizing matters
An oversized heat pump short-cycles, runs inefficiently, and doesn't dehumidify properly. An undersized one can't keep up in deep cold, runs constantly, and wears out faster.
Our approach
We do an in-home assessment that looks at:
- Square footage and ceiling height.
- Insulation quality (visible R-values, age of construction).
- Window count, orientation, and quality.
- Exposure (windward, sheltered, coastal).
- Existing or planned ductwork.
We don't size off a chart from the back of a brochure. We measure the home.
Common sizes for NL homes
- 2.5 ton: smaller homes, well-insulated, good layout.
- 3 ton: typical mid-size home.
- 4 ton: larger homes or homes with weaker insulation.
- 5 ton: large homes or those with significant exposure.
Aux heat is part of sizing
Most NL central ducted installs include a 10 kW or 15 kW auxiliary heat kit. The combined heat pump + aux capacity is what matters during the deep cold.
