Loves Air Explains How to Choose the Right Size Air Conditioning Unit for Your House in the Central Valley
- AC cooling capacity is typically measured in AC tonnage.
- Choosing the right AC tonnage depends on multiple factors, including home size, Insulation, and climate zone.
- An improperly sized air conditioner cannot cool your home effectively and leads to unnecessarily high energy bills.
- Consulting a professional HVAC technician is the best way to determine the right AC size for your home.
What Is AC Tonnage? Tonnage and BTU Explained
AC tonnage is the standard measurement for an air conditioner’s capacity to remove heat from your home. Despite the name, tonnage doesn’t refer to the weight of your air conditioner — it actually refers to the cooling power provided by one ton of ice melting over 24 hours. You might also hear AC power measured in BTUs (British Thermal Units), with one ton of power equal to 12,000 BTUs.
When thinking about tonnage and BTUs, it’s helpful to remember that air conditioners don’t actually make cold air — they pull heat out of your home and transfer it outside. The AC rating refers to how many units of heat energy your air conditioner can remove from your indoor air in one hour. While tonnage and BTUs measure the same thing, tonnage is the most common measurement since the numbers are smaller and easier to use.
How to Find Your AC’s Tonnage
If you’re worried about how to find AC tonnage, it’s no sweat — your manufacturer has already done the heavy lifting for you. All you need to find your AC’s tonnage is to locate the manufacturer’s date plate, which is typically on the outdoor condenser unit. On the data plate, you’ll find the model number for your air conditioner, and within that model number, you’ll see an even number between 18 and 60. This number is your air conditioner’s BTU rating. To calculate AC tonnage, simply divide the BTU by 12, and you’ll have your tonnage rating.
Why Is It Important to Properly Size Your AC Unit
A properly sized AC unit is essential for efficiently cooling your home, especially during the Central Valley’s scorching summers. An air conditioner that isn’t the right size won’t be able to deliver the right amount of cooling power, so you’ll either end up with a home that’s too warm or you’ll be left with soaring energy bills. When you book an air conditioner installation with Loves Air, we promise a 100% satisfaction guarantee on all services, so you’ll never have to deal with the hassle of an improperly sized AC unit.
Signs Your AC Is Undersized
When your air conditioner is too small for your home, it’s forced to work overtime to fight the Northern California heat. Undersized AC unit problems include an AC unit that runs continuously, leading to higher energy costs and a system that wears out prematurely. You might also notice that your home is never as cool as the temperature you’ve set on your thermostat or that some rooms are dramatically warmer than others.
Signs Your AC Is Oversized
When shopping for a new type of AC, it can be tempting to err on the side of caution and buy one that’s larger than you need. Unfortunately, an oversized AC can cause just as many problems as an undersized unit. If your AC is too big for your home, you might notice frequent short cycling, with the unit turning on and off rapidly every 10 minutes or less. When your AC shuts off before performing a full cycle, it often leads to inconsistent temperatures in different zones, especially on upper floors. Because your AC draws more power than it needs to, you’ll also often end up with costly energy bills.
How Do Professionals Determine the Right AC Size
Determining the right AC size for your home is about more than just square footage. When you call our team at Loves Air to install your new air conditioner, we’ll perform a comprehensive heat load calculation based on several key factors, including:
- The layout and square footage of your home, including the height of your ceilings
- The placement, size, and quantity of your windows and doors
- Your home’s insulation levels
- The intense cooling demands of California’s Central Valley
- Ductwork, ventilation, and airflow inside your home
- The number of occupants and heat-generating appliances inside your home
- The type of AC you want, including central AC and ductless mini-splits
- Your personal cooling preferences
What to Do if Your AC Is the Wrong Size?
If your AC is the wrong size, the best solution is to contact a professional for AC replacement. Although this may sound like a significant investment, continuing to use an AC that’s the wrong size will cost you far more than necessary in monthly utility bills. Instead, call the licensed HVAC team at Loves Air and find out why we’re rated the best in the Central Valley for AC service. Our HVAC pros will properly size and install your new AC unit with full satisfaction guaranteed. If you don’t feel ready to install a new unit at this time, we can talk to you about other strategies, like home insulation, to help you manage with your current AC.
