No, a bigger AC unit won’t automatically cool your home better. In fact, oversizing the unit will make the system less efficient and could make your home uncomfortable, especially in humid weather.

Sizing the system is the most crucial step in a Suffolk County AC installation. Learn why, and see how a top-rated Long Island HVAC contractor will ensure that your new unit perfectly suits your home.

How an Oversized AC Unit Causes Problems

Air conditioners are designed to run in sustained cycles. During the cycle, the system doesn’t just cool your home; it also removes moisture. If the system is too large for the space it’s cooling, it will hit the target temperature quickly before turning off or slowing the compressor. This is a pattern known as short cycling. It will prevent your system from dehumidifying your home, leaving interiors feeling clammy, even though the temperature is where you want it.

• Short cycling puts additional mechanical stress on the compressor, reducing the service life of the air conditioner.
• Oversizing doesn’t mean better cooling. It means paying more for something that won’t last as long.
• Even with variable-speed compressor systems, oversizing won’t make your unit more efficient or performant; it will just hit you harder on the installation bill.

The best HVAC contractors perform manual load calculations to determine the best size for an air conditioner installation in Suffolk County.

How Professionals Size Air Conditioners

A simple online calculator will size an AC based on the square footage of your home, but this is only part of a detailed load calculation. An experienced HVAC technician will look at other factors when planning the AC installation, including:

• The types of materials used to construct your home.
• The layout of rooms, hallways, and living spaces.
• The number of heat-producing appliances in your home.
• The number of occupants.
• Airflow throughout the home.
• The quality of the insulation (R-value).
• Sunlight exposure and heat gain through windows.

The final calculation is called a Manual J Load Calculation, and it’s the most crucial aspect of an AC installation, outside of choosing the unit itself. At Soundview Heat and Air Conditioning Corp., we perform detailed calculations so that your home is cool and comfortable, without overspending on AC tonnage that you don’t need.

What if My System is Oversized But Not Ready for Replacement?

There are options to modify your system to make your AC more efficient. A refrigerant charge adjustment or airflow modification can help.

Many homeowners find themselves mid-lifecycle with an air conditioner that’s too large for the home. This happens often in older homes with weak insulation, where the original contractor decided to brute force the cooling performance.
