Finding the appropriate HVAC system size for your home is essential. It has a big impact on your comfort and your energy bills. In this HVAC sizing guide, the specialists at Superior Comfort Systems will explain how to determine the right 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 convenience.

How Does HVAC System Size Affect Your 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 struggle to keep up in extremely warm or cold weather. However, an HVAC system that's oversized is inefficient, wastes money and can lead to complications that make your home less comfortable.

Crucial Factors Professionals Consider for HVAC Sizing in Hendersonville, NC

To select the appropriate HVAC system size for a home, the HVAC installation specialists at Superior Comfort Systems carry out a Manual J load calculation to determine how many British Thermal Units (BTUs) are needed 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 significant factor in picking the size of your HVAC system. How much space will your new HVAC system have to heat and cool?
  • Amount of insulation: A properly insulated home retains the indoor temperature more efficiently, which can influence how much heating and cooling power you need.
  • Local Weather: The local climate in Hendersonville, NC, has an important role in determining the appropriate size HVAC. Homes in hotter climates might need a system with an increased cooling capacity, while chillier regions may require less.
  • Number of windows: Windows can be a significant source of energy loss. The number, size, type of glass used, and whether they’re single paned or double paned can considerably influence heating and cooling requirements.
  • Sun exposure: A home that gets a substantial sunlight will automatically 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 impact the appropriate HVAC size.

HVAC Size Mistakes Homeowners Often Make

A frequent mistake homeowners make when sizing their own HVAC system is to focus only on square footage. Although the square footage of your home has a significant impact on what size HVAC you need, other factors 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 crucial to have a qualified HVAC technician carry out a Manual J calculation, which takes all the essential aspects of your home into consideration to establish the appropriate HVAC size.

Why Is Your Home HVAC System Size Important?

An incorrectly sized system can cause comfort problems and drive up your monthly power bills. Here's a deep dive into 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 excessive wear and tear. This can lead to breakdowns and even require premature HVAC replacement.
  • An uncomfortable home: Small HVAC systems lack the necessary capacity to heat and cool your entire residence, which can result in hot, stuffy rooms or areas of your home that are chilly and uncomfortable.
  • Higher energy expenses: 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 operates more efficiently and helps to reduce your monthly bills.

Problems with HVAC systems that are too big

  • Unnecessary expenses: Larger HVAC systems typically have a higher purchase price, so purchasing more heating and cooling capacity than your home needs is a waste of money.
  • Shorter system life and breakdowns: HVAC systems that are too big often start and stop frequently, referred to as short cycling. This can cause wear and tear on your equipment, reducing 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 cause indoor air quality issues, such as mold growth.
