Choosing the right HVAC system size for your home is crucial. It impacts your comfort and your power expenses. In this HVAC sizing guide, the experts at Just Right Heating and Cooling will explain how to select the best size of heating and cooling system for your home, what features they take into account and why selecting the most suitable size HVAC is so important to your comfort.

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 comfortable. It shouldn't struggle to keep up in extremely warm or frigid weather. However, an HVAC system that's too large is inefficient, increases your energy expenses and can lead to complications that make your home less comfortable.

Crucial Features Pros Consider for HVAC Sizing in Goshen, OH

To determine the appropriate HVAC system size for a home, the HVAC installation specialists at Just Right Heating and Cooling perform 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:

  • Home size: The size 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 be required to keep comfortable?
  • Amount of insulation: A well- insulated home maintains the indoor temperature better, which can influence how much heating and cooling power you demand.
  • Local Weather: The local climate in Goshen, OH, plays a major role in finding the right size HVAC. Homes in hotter climates might need a system with a higher cooling capacity, while chillier regions may demand less.
  • Window placement and size: Windows can be a significant source of energy loss. The number, dimensions, type of glass used, and whether they’re single paned or double pane can greatly influence heating and cooling requirements.
  • Sun exposure: A home that receives a substantial sunlight will inherently be warmer than one that doesn't, which impacts central air sizing. Positioning in relation to prevailing winds and number of nearby shade trees also influence the appropriate HVAC size.

Most Common DIY HVAC Size Mistakes

A frequent mistake homeowners make when sizing their own 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 factors also influence how much heating and cooling capacity is required 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 elements into consideration to establish the appropriate HVAC size.

Why Does HVAC System Size Matter?

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

Undersized HVAC system problems:

  • Reduced lifespan and breakdowns: HVAC systems that are too small often run constantly to attempt to regulate the temperature of a home, leading to more wear and tear. This can cause breakdowns and even require premature HVAC replacement.
  • An uncomfortable home: Small HVAC systems are too weak to heat and cool your whole home, which can result in hot, stuffy rooms or areas of your home that are uncomfortably cold.
  • Increased energy expenses: An underpowered HVAC system that operates nonstop trying to keep up uses more energy, running up 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 tend to cost more money, so purchasing more heating and cooling capacity than your home needs is an unnecessary expense.
  • Shorter system life and breakdowns: HVAC systems that are too big often start and stop frequently, referred to as short cycling. This can lead to wear and tear on your equipment, reducing its service life or requiring HVAC repair.
  • Excessive indoor humidity: An HVAC system should control the moisture level in your home, but an oversized HVAC system may lack adequate runtime to accomplish that task. This can lead to indoor air quality issues, and encourage the growth of mildew or mold.
