Right Size AC Unit | AC Installation in Garner, NC

Choosing the right size AC unit is more than just about comfort. It affects your home’s energy efficiency, utility bills, and indoor air quality.

If the unit is too small, it will struggle to cool your home.

If it’s too large, it may cycle on and off too often, leading to uneven cooling & higher costs.

Getting the size right is one of the most important steps in planning AC installation in Garner, NC—it’s what keeps your home comfortable for years to come.

Start with Your Home’s Square Footage

Begin by figuring out your home’s total square footage.

That number is what your installer will use to match you with the right cooling capacity, measured in British Thermal Units (BTUs).

For example:

1,000–1,200 sq. ft.: about 21,000 BTUs
1,500–2,000 sq. ft.: about 30,000–34,000 BTUs
2,000–2,500 sq. ft.: about 34,000–40,000 BTUs

These are general guidelines, but your home’s layout, insulation, & ceiling height can also affect the required size.

Factor in Sunlight and Windows | AC Installation in Garner, NC

Natural light is great, but it can impact cooling needs. Homes with many large windows or those facing direct sunlight for most of the day may require a slightly larger unit.

Conversely, a well-shaded home might need less cooling power.

The type of window glass also matters; double-pane windows help keep heat out better than single-pane windows.

Don’t Forget Ceiling Height and Insulation

A home with higher ceilings means more space to cool. Poor insulation will also make your AC work harder, no matter the size.

Before installing an AC unit, check your attic insulation, wall insulation, & weather stripping.

Good insulation helps maintain cool air inside, allowing you to choose the right unit without overcompensating.

Think About Household Habits

Every family uses their home differently. If you cook often, the heat from the kitchen can raise indoor temperatures.

A home office filled with electronics can generate extra heat. If your household prefers cooler temperatures, you might need more cooling capacity.

Consider these daily patterns before deciding.
