What Size Air Conditioner System Should You Install?

May 19, 2025

Choosing the right size air conditioner for your home is a crucial decision that impacts not only your comfort but also your energy bills. An air conditioner that's too small won't cool your home effectively, while one that's too large will cycle on and off too quickly, wasting energy and putting unnecessary strain on the unit. In this post, we'll explore key factors you need to consider when determining the optimal size for your new air conditioning system.


Consider the Size of Your Home

The size of your home is the primary factor that dictates the size of your air conditioning system. Larger homes generally require more cooling power, which means a larger unit. The cooling capacity of an air conditioner is measured in BTUs (British Thermal Units), and a rough rule of thumb is that you need about 20 BTUs per square foot of living space, in our experience. However, this is a very general estimate and other factors such as ceiling height, insulation, and the number of windows can influence the necessary BTU capacity.


Understand Your Area's Climate

It's also essential to consider the climate in which you live when determining the size of your air conditioner system. In hot and humid areas, you might need a more powerful system to cope with the extreme weather conditions. According to This Old House, almost 90% of homes in the United States are equipped with air conditioning units. This high percentage underscores the importance of factoring in your specific local climate conditions, as it can significantly affect the cooling needs of your home.


Consider the Energy Efficiency

Moreover, the energy efficiency of the air conditioner system you install plays a significant role. Units with higher SEER (Seasonal Energy Efficiency Ratio) ratings are more efficient and can handle higher cooling loads without excessive energy consumption. This can be particularly beneficial over the long term as energy costs continue to rise. Always consider energy-efficient models that provide the best balance between capacity and power consumption.


Selecting the right size air conditioner system for your home requires more than just a quick glance at square footage. You must consider several factors, including the layout of your home, climate, energy efficiency, and potential future changes in home usage. Consulting with an HVAC professional can help you take these variables into account, ensuring you select a system that offers optimal performance and efficiency.

When people think about HVAC problems, they usually point to the air conditioning unit itself. But one of the most overlooked causes of high energy bills and inconsistent home comfort is hiding in plain sight—your air ducts. At On Deck AC, we’ve seen it time and again: a perfectly functioning HVAC system underperforming because of ductwork that’s leaking, blocked, or poorly installed. The truth is, even the most advanced HVAC system can't operate efficiently if the air can’t flow freely and cleanly throughout your home or building. Why Air Ducts Matter More Than You Think Your air ducts are essentially the veins of your HVAC system, distributing heated or cooled air throughout your space. But over time, ducts can suffer from: Leaks or holes caused by age, pests, or poor installation Disconnected joints or loose fittings Dust and debris buildup that restricts airflow Poor insulation, especially in attics or crawlspaces Improper sizing or design, leading to pressure imbalances The result? Up to 30% of your heated or cooled air could be lost before it even reaches your rooms. That means your system has to work harder, run longer, and ultimately cost you more in energy and repairs. Signs of Air Duct Inefficiency Not sure if your ductwork is the problem? Here are some common warning signs: Certain rooms are always hotter or colder than others Higher-than-normal energy bills despite regular HVAC maintenance Musty or dusty smells when your system is running Weak airflow from vents Excess dust buildup around your home What Can Be Done? At On Deck AC, we specialize in identifying and solving ductwork inefficiencies. Our trained technicians perform detailed inspections and airflow testing to locate: Leaks and disconnections Blockages or restrictions Areas needing sealing or insulation Poorly designed or outdated duct layouts Once identified, we offer solutions that may include duct sealing, repairs, cleaning, or even complete redesign if needed. The Benefits of Efficient Ductwork Fixing duct issues not only boosts your system’s performance—it improves your entire home environment: Lower energy bills (sometimes significantly) More consistent temperatures room-to-room Better indoor air quality with reduced allergens and dust Less strain on your HVAC system, extending its lifespan A quieter, more comfortable home Ready to Breathe Easier?
