Is a Larger Air Conditioner Really More Efficient?

At T-Mark Plumbing, Heating & Cooling, we often encounter homeowners who believe that installing a larger air conditioning unit will result in better cooling and improved efficiency. Today, we’re here to debunk this common myth and explain why proper sizing is crucial for optimal AC performance.

The Myth: Bigger AC Units Cool Better and Save Money

Many people assume that a larger air conditioner will:

• Cool their home faster
• Maintain lower temperatures more easily
• Use less energy in the long run

The Truth: Proper Sizing is Key

In reality, an oversized AC unit can lead to several issues:

1. Short Cycling

Oversized units cool spaces too quickly, causing frequent on-off cycles. This leads to:

• Increased wear and tear on the system
• Higher energy consumption
• Reduced lifespan of the unit

2. Inadequate Dehumidification

Properly sized ACs remove humidity as they cool. Oversized units don’t run long enough to effectively dehumidify, resulting in:

• Clammy, uncomfortable indoor air
• Potential mold growth

3. Higher Operating Costs

Contrary to popular belief, larger units often consume more energy due to inefficient cycling.

The Solution: Professional AC Sizing

To ensure optimal efficiency and comfort, it’s crucial to have a professional HVAC technician perform a load calculation. This takes into account factors such as:

• Home size and layout
• Insulation levels
• Window placement and type
• Local climate
