Choosing the correct HVAC system size for your home is essential. It has a big impact on your ability to enjoy your home and your power expenses. In this HVAC sizing guide, the specialists at Korando Heating & Cooling, Inc. will explain how to choose the correct size of heating and cooling system for your home, what features they take into account and why picking the best size HVAC is so important to your comfort.

Why HVAC System Size Matters for Home Comfort and Efficiency

Proper HVAC size is different for every home. Your HVAC system needs adequate heating and cooling capacity to make your entire home comfortable. It shouldn't have to work extremely hard to keep up in extremely hot or chilly weather. However, an HVAC system that's oversized is inefficient, costs more up front and can lead to complications that make your home less comfortable.

Key Factors Professionals Consider for HVAC Sizing in Chester, IL

To select the correct HVAC system size for a home, the HVAC installation specialists at Korando Heating & Cooling, Inc. carry out a Manual J load calculation to determine how many British Thermal Units (BTUs) are required to heat and cool and the home. A Manual J calculation evaluates multiple features of your home, such as:

  • Size of the home: The size of the home is arguably the most important factor in choosing the size of your HVAC system. How much space will your new HVAC system be required to heat and cool?
  • Insulation levels in the home: A properly insulated home maintains the indoor temperature more effectively, which can affect how much heating and cooling capacity you need.
  • Regional Climate: The local climate in Chester, IL, has a significant role in identifying the correct size HVAC. Homes in hotter climates may require a system with an increased cooling capacity, while chillier regions may need less.
  • Window size: Windows can be a considerable source of energy loss. The number, size, type of glass used, and whether they’re single paned or double paned can significantly affect heating and cooling requirements.
  • Amount of sun: A home that receives a considerable sunlight will naturally be warmer than one that doesn't, which impacts central air sizing. Orientation in relation to prevailing winds and number of nearby shade trees also influence the correct HVAC size.

HVAC Size Mistakes Homeowners Often Make

A frequent mistake homeowners make when determining the size of their HVAC system is to rely solely on square footage. Although the square footage of your home has a significant impact on what size HVAC you need, other considerations also influence how much heating and cooling capacity is required to keep your home comfortable.

Another typical mistake is not engaging a professional. It's essential to have an experienced HVAC technician conduct a Manual J calculation, which takes all the essential factors into consideration to determine the appropriate HVAC size.

Why Is Your Home HVAC System Size Important?

An improperly sized system can lead to comfort problems and increase expenses. Here's a closer look at the pitfalls of a incorrectly sized HVAC:

Problems with HVAC systems that are too small:

  • Reduced lifespan and breakdowns: HVAC systems that are too small often seem to run all the time to try to heat or cool a home, leading to more wear and tear. This can lead to breakdowns and even require premature HVAC replacement.
  • An unpleasant home: Small HVAC systems are too weak to heat and cool your entire residence, which can result in hot, stuffy rooms or areas of your home that are chilly and uncomfortable.
  • Increased energy expenses: An underpowered HVAC system that runs continuously trying to keep up uses more energy, increasing your monthly power bills and wasting your hard-earned money. A properly sized and energy-efficient HVAC system uses less power and helps to lower your monthly bills.

Issues from oversized HVAC systems

  • Unnecessary expenses: Larger HVAC systems are usually more costly, so buying more heating and cooling capacity than your home requires is an unnecessary expense.
  • Shorter system life and breakdowns: HVAC systems that are oversized often start and stop frequently, referred to as short cycling. This can lead to wear and tear on your machine, reducing its service life or requiring HVAC repair.
  • Increased humidity: An HVAC system should balance indoor air moisture, but an oversized HVAC system often completes its cycle before it has time to accomplish that task. This can result in indoor air quality issues, such as mold growth.
