Choosing the appropriate HVAC system size for your home is vital. It affects your comfort and your power expenses. In this HVAC sizing guide, the professionals at House of Heating Incorporated will explain how to determine the right size of heating and cooling system for your home, what factors they take into account and why selecting the most suitable size HVAC is so important to your convenience.

How Does HVAC System Size Affect Your Home Comfort and Efficiency

Proper HVAC size varies for each home. Your HVAC system needs sufficient heating and cooling capacity to make your entire home cozy. It shouldn't struggle to keep up in extremely warm or chilly weather. However, an HVAC system that's too large is inefficient, wastes money and can lead to complications that make your home less agreeable.

Crucial Features Professionals Consider for HVAC Sizing in Marshfield, WI

To choose the appropriate HVAC system size for a home, the HVAC installation experts at House of Heating Incorporated perform a Manual J load calculation to determine how many British Thermal Units (BTUs) are necessary to heat and cool and the home. A Manual J calculation evaluates several factors, such as:

  • Size of the home: The total area of the home is arguably the most crucial factor in selecting the size of your HVAC system. How much space will your new HVAC system need to keep comfortable?
  • Home insulation: A properly insulated home retains the indoor temperature more efficiently, which can influence how much heating and cooling power you require.
  • Regional Climate: The local climate in Marshfield, WI, has a major role in identifying the right size HVAC. Homes in sunnier climates may require a system with an increased cooling capacity, while cooler regions may require less.
  • Number of windows: Windows can be a significant source of energy loss. The number, dimensions, type of glass used, and whether they’re single or double paned can greatly affect heating and cooling requirements.
  • Sun and shade: A home that gets a lot of 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 influence the correct HVAC size.

Most Common DIY HVAC Size Mistakes

A frequent mistake homeowners make when determining the size of their HVAC system is to base their decision on square footage. Although 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 comfortable.

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

Why Is Your Home HVAC System Size Important?

An inadequately sized system can cause comfort problems and increase expenses. Here's a deep dive into the pitfalls of a incorrectly sized HVAC:

Undersized HVAC system problems:

  • Shorter system life and breakdowns: HVAC systems that don't have enough power often seem to run all the time to strive to maintain the temperature in a home, leading to more wear and tear. This can cause breakdowns and even require premature HVAC replacement.
  • An uncomfortable home: Small HVAC systems don't have enough power to heat and cool your entire residence, which can cause hot, stuffy rooms or areas of your home that are uncomfortably cold.
  • Increased energy bills: An underpowered HVAC system that works constantly trying to keep up uses more energy, driving up 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.

Issues from oversized HVAC systems

  • Wasted money: Larger HVAC systems typically have a higher purchase price, so investing in more heating and cooling capacity than your home requires is an unnecessary expense.
  • Shorter system life and breakdowns: HVAC systems that are excessively large often start and stop frequently, referred to as short cycling. This can result in wear and tear on your machine, reducing its service life or requiring HVAC repair.
  • Humidity issues: 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.
