Multi-family first

38% of North Myrtle Beach homes are single-family detached, 5% are in two- to four-unit buildings and 49% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4551280, checked 2026-10-19).

With 49% of North Myrtle Beach homes in buildings of five or more units and 38% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 18% of North Myrtle Beach homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4551280, checked 2026-10-19), the landlord signs the quote in many of them.

North Myrtle Beach has 15 points fewer detached houses than Horry County overall (53%) and 24 points more five-plus-unit buildings than the county's 25% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US45051, checked 2026-10-19).

Heating fuel in North Myrtle Beach

North Myrtle Beach tracks Horry County on housing age, with the county at 1% pre-1940 and 49% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US45051, checked 2026-10-19).

The median North Myrtle Beach home was built in 1997 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4551280, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4551280, checked 2026-10-19).

Sizing for Horry County

Heating design temperature: 28F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Horry County row, 99% heating, PDF pages 105 to 107 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.

That 28F figure is the Horry County cold-day number a North Myrtle Beach heat pump is sized against, so ask the installer to show the system's heating output at 28F, not at the milder rating-label temperature.

Next step

Ask for the heat-loss calculation room by room; the median North Myrtle Beach home has 4.9 rooms and was built around 1997, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
