AC Installation: Why Size Matters

Heating and air conditioning installation checklist on top of a new outdoor HVAC unit.

Summer is progressing right along, and we’re dealing with hot temperatures daily. If you’ve lived in this area for even just a year, you know just how uncomfortable it can be when temperatures soar to their highest. This means that if you’re looking for an AC installation right now, you’re likely in a hurry to get a new one, right?

We understand that sense of urgency, but we really encourage our customers to slow down and make their decisions about home comfort carefully. Failing to do so can leave you with an inefficient and ineffective solution for your home cooling. Factors such as the size and efficiency of the unit significantly influence the AC installation cost, so it’s important to consider these aspects. AC replacement basics to consider can help guide your decision-making process.

One component of this is sizing. We’re not talking about the volume of the air conditioner itself, but rather how many “tons” of cooling it can handle (that is, how many tons of ice would be melted by the heat drawn out of your home per hour–which is measured in British Thermal Units–BTUs). An “oversized” system can be just as detrimental to your comfort and home efficiency as an undersized one. Read on to learn more about this, especially if you’re unsure whether your current system is truly the right fit for your space. It’s crucial to factor in considerations like installation costs and cooling capacity when choosing the right AC unit. Read on to learn more about this.

Why is correct sizing important for heating and air conditioning installation?

Correct sizing ensures your system can efficiently heat and cool your home without wasting energy. An undersized unit runs constantly and struggles to maintain comfort, while an oversized unit short-cycles, causing poor humidity control, uneven temperatures, and premature wear. Proper sizing leads to better efficiency and system longevity.

Introduction to Air Conditioning Installation

Air conditioning installation is a crucial process that requires careful consideration and planning to ensure optimal performance and energy efficiency. A new air conditioner can provide improved cooling performance, reduced energy bills, and increased comfort for homeowners in Des Moines and surrounding areas. The air conditioning installation process involves several complex tasks, including removing the old AC unit, installing the new system, and connecting refrigerant lines, electrical wiring, and drainage systems. Only EPA-certified personnel can remove, handle, and dispose of refrigerant in an air conditioning system, ensuring compliance with environmental regulations.

It’s essential to choose the right AC unit for your home, considering factors such as cooling costs, energy efficiency, and proper sizing. ENERGY STAR®-certified models are a great choice for efficiency, as they meet strict energy performance standards. A professional AC installer can help you navigate the installation process, ensuring that your new air conditioner is installed correctly and functions efficiently. New air conditioning units tend to be larger to accommodate more efficient coils compared to older systems. The cost of air conditioning installation can vary depending on several factors, including the type of AC unit, existing ductwork, and installation cost. If you’re unsure where to begin, is it time for new installation is a great starting point.

Homeowners can expect to save money on their energy bills with a new, energy-efficient air conditioner, which can also increase the value of their home. Modern AC systems improve indoor air quality and comfort with features for air filtration and humidity control. Regular system testing and maintenance can help extend the lifespan of your air conditioner and prevent common signs of wear and tear. A well-maintained air conditioner typically lasts between 10 to 20 years. By investing in a professional installation, you can ensure that your home remains cool and comfortable for years to come.

Why AC Unit Size Matters More Than You Think

The first step in purchasing a home comfort system of any kind is to find the one that best matches your specific home, and we mean that literally. Properly sizing your cooling system is the only way you’ll be able to meet your home’s unique cooling needs. Additionally, recognizing the signs that indicate when an air conditioning system needs to be replaced is crucial for maintaining efficiency and comfort. Signs you need a new AC are essential to know as you evaluate your current unit’s condition.

As we said above, when we talk about an air conditioner’s “size” we’re not talking about the volume of the system itself or how much space it takes up in your home. We’re talking about the amount of energy output in comparison to the relative size of your home, plus other factors of your home.

Bigger isn’t always better, and this is especially true when it comes to your air conditioner. An air conditioner that isn’t properly sized will cause inefficiency through wasted energy, and therefore wasted money.

An undersized air conditioner simply won’t be able to effectively cool the space it is installed in, while an oversized air conditioner will go through a process called “short-cycling” where it cycles on and off rapidly instead of going through regular cycles as it meant to. Various elements, such as environmental conditions and the installation process, can affect the lifespan and functioning of air conditioning units.

An oversized air conditioner can also lead to inadequate humidity control. By cooling the space too quickly, it doesn’t run long enough to effectively remove moisture from the air, resulting in a clammy and uncomfortable indoor environment. Proper sizing ensures balanced humidity levels, enhancing overall comfort.

Short-cycling doesn’t just impact the lifespan of your system—it also affects indoor air quality. When the air conditioner fails to complete its full cycle, it can leave excess humidity in the air, making your home feel clammy and uncomfortable. This issue often signals that your AC needs professional help, and may even warrant a repair or replacement evaluation. This can even contribute to the growth of mold or mildew in more humid regions, compounding health risks and maintenance costs over time.

An air conditioner is designed to run its compressor in 15-minute increments, 2-3 times an hour. Short-cycling increases wear and tear on the system, which in turn increases repair needs and decreases overall lifespan.

To avoid this, our professionals do what’s called a cooling load calculation, where we look at the square footage of your home or space you’re cooling, but also how many windows and doors are in the space, how high the ceilings are, and what kind of insulation is in the space. Understanding the process behind this assessment can empower you to make more informed decisions during the installation process. Additionally, the ideal location for an air conditioner installation ensures proper airflow and maximum efficiency. Replacing an outdated unit can lead to significant cost savings and improved efficiency.

It’s also essential to consider your household’s specific cooling habits. For example, if certain rooms in your home are consistently occupied and require cooler temperatures, this might influence the overall capacity needed for your system. Similarly, accounting for heat-generating appliances or electronics in heavily used areas ensures your AC can keep up with demand efficiently without overworking.

In addition to the factors mentioned, it’s essential to consider the orientation of your home and the local climate. Homes with significant sun exposure or located in warmer regions may require systems with higher cooling capacities to maintain comfort. Conversely, homes in shaded areas or cooler climates might need less capacity. Tailoring the air conditioner’s size to these specifics ensures optimal performance and energy efficiency.

Short-cycling can also result in inconsistent indoor temperatures, leaving some areas of your home too warm while others are overly cooled. This uneven cooling not only affects comfort but may lead to higher humidity levels in certain parts of your home, which can promote mold growth and reduce overall air quality. Proper sizing eliminates these risks, ensuring your home remains consistently cool and comfortable.

Once we determine the proper sizing for you, then we can go about having it installed in your home. But the sizing is what makes it so important for you to hire a professional! After installation, testing is performed on the AC unit to ensure proper operation. During testing, the technician verifies that the refrigerant is flowing and the air conditioner is conditioning the air properly. Please don’t hesitate to reach out to us with any questions you may have.
