Finding the right HVAC system size for your home is vital. It impacts your home enjoyment and your energy bills. In this HVAC sizing guide, the experts at DNA Heating & Air will explain how to select the correct size of heating and cooling system for your home, what features they take into account and why selecting the ideal size HVAC is so important to your satisfaction.

How Does HVAC System Size Affect Your Home Comfort and Efficiency

Proper HVAC size is different from home to home. Your HVAC system needs adequate heating and cooling capacity to make your entire home pleasant. It shouldn't have to work extremely hard to keep up in extremely warm or cold weather. However, an HVAC system that's too big is inefficient, costs more up front and can lead to complications that make your home less enjoyable.

Crucial Features Pros Consider for HVAC Sizing in Columbus, GA

To select the correct HVAC system size for a home, the HVAC installation experts at DNA Heating & Air conduct 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 elements, such as:

  • Size of the home: The total area of the home is arguably the most significant factor in choosing the size of your HVAC system. How much space will your new HVAC system need to heat and cool?
  • Home insulation: A well- insulated home retains the indoor temperature better, which can affect how much heating and cooling power you demand.
  • Climate: The local climate in Columbus, GA, has an important role in determining the correct size HVAC. Homes in hotter climates may require a system with a greater cooling capacity, while cooler regions may require less.
  • Window placement and size: Windows can be a considerable source of energy loss. The number, dimensions, type of glass used, and whether they’re single or double pane can considerably impact heating and cooling requirements.
  • Amount of sun: A home that gets a considerable sunlight will automatically be warmer than one that doesn't, which affects central air sizing. Positioning in relation to prevailing winds and number of nearby shade trees also affect the proper HVAC size.

HVAC Size Mistakes Homeowners Often Make

A frequent mistake homeowners make when choosing the size of home HVAC system is to base their decision on square footage. While the square footage of your home has a big impact on what size HVAC you need, other elements also influence how much heating and cooling capacity is necessary to keep your home pleasant.

Another typical mistake is not engaging a professional. It's essential to have a skilled HVAC technician perform a Manual J calculation, which takes all the essential factors into consideration to find the correct HVAC size.

Why Does HVAC System Size Matter?

An improperly sized system can cause 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 don't have enough power often seem to run all the time to attempt to regulate the temperature of a home, leading to increased wear and tear. This can result in breakdowns and even require premature HVAC replacement.
  • An uncomfortable home: Small HVAC systems are too weak to heat and cool your entire living space, which can result in hot, stuffy rooms or areas of your home that are uncomfortably cold.
  • Higher energy bills: An underpowered HVAC system that runs continuously trying to keep up uses more energy, increasing your monthly power bills and costing you money. A properly sized and energy-efficient HVAC system consumes less energy and helps to reduce your monthly bills.

Problems with HVAC systems that are too big

  • Wasted money: Larger HVAC systems tend to cost more money, so purchasing more heating and cooling capacity than your home needs is a waste of money.
  • Less service life and breakdowns: HVAC systems that are too big often start and stop frequently, referred to as short cycling. This can result in wear and tear on your equipment, shortening its service life or requiring HVAC repair.
  • Increased humidity: An HVAC system should control the moisture level in your home, 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.
