Why Is Properly Sizing Your HVAC System So Important?

When we speak about the sizes of HVAC systems, some of you are probably thinking, “The bigger, the better”; Wrong! Bigger systems don’t automatically yield the best results and conditions for your home. Others will opt for smaller units due to affordability. The topic is often misunderstood, but in layman’s language, undersized and oversized HVAC systems can be problematic. So why do our HVAC experts at Central Florida necessitate the need for proper HVAC system sizing?

What is HVAC system sizing?

The approach describes special calculations used to determine which system best suits your cooling and heating needs. Your HVAC technician will measure your home in square footage and conduct some calculations that arrive at the right size of the HVAC system for your home.

Why is the practice essential?

Maintaining energy efficiency

As a homeowner, you are probably aware that heating and cooling costs account for a significant amount of your energy bills. When investing in an HVAC system, you want something that will be kind on your energy bills. The sizing of your HVAC system plays a significant role in ensuring that your bills are reasonable. But how? An oversized HVAC system experiences short cycles, struggling to maintain your indoor air temperature and quality. It wastes a lot of energy regulating temperatures frequently.

On the other hand, an undersized unit runs continually trying to match up to your home’s cooling and heating needs. Eventually, the continuous runs translate to escalated energy bills. Proper HVAC system sizing helps you determine the right capacity of the equipment you need for your home to save you utility costs.

Even cooling and heating efforts

HVAC systems are designed to alleviate humid conditions and regulate temperatures to preferred settings. You wouldn’t achieve these with an undersized or oversized system. For instance, an oversized HVAC unit will have a hard time controlling humidity, causing fluctuating room temperatures. These conditions created by using an oversized system cause duct leakage, encourage mildew growth and reduce your home’s air quality. Undersized systems struggle to adjust humidity and temperature, causing frequent breakdowns, uneven cooling, and heating effects, and expensive repairs.

System longevity

Proper HVAC unit sizing ensures that you shop for a system that can stand the test of time. Oversized units suffer from short cycles that cause wear and tear, significantly reducing their lifespan. Undersized units constantly run to satisfy the heating and cooling demands of your home, which similarly results in wear and tear of running parts, duct-work, and air filters. The stress on your HVAC units makes it hard for your system to live up to its anticipated life expectancy.

Who should you go to for HVAC system sizing?

While it’s important to research and explore your options, it’s equally essential to involve an expert in the buying and decision-making process. Your HVAC contractor will make the necessary calculations to ensure that you are investing in the right size of the HVAC system for your home.
