Finding the correct 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 professionals at True Temp Heating & Air Conditioning will explain how to choose the right size of heating and cooling system for your home, what factors they take into account and why choosing the ideal size HVAC is so important to your satisfaction.

How Does HVAC System Size Affect Your Home Comfort and Efficiency

Proper HVAC size differs from home to home. Your HVAC system needs enough heating and cooling capacity to make your entire home cozy. It shouldn't struggle to keep up in extremely hot or frigid weather. However, an HVAC system that's oversized is inefficient, increases your energy expenses and can cause problems that make your home less agreeable.

Key Factors Pros Consider for HVAC Sizing in Chatsworth, GA

To determine the correct HVAC system size for a home, the HVAC installation experts at True Temp Heating & Air Conditioning 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 features of your home, such as:

  • Square footage: The size of the home is arguably the most important factor in picking the size of your HVAC system. How much space will your new HVAC system have to keep comfortable?
  • Insulation levels in the home: A fully insulated home retains the indoor temperature more efficiently, which can influence how much heating and cooling capacity you demand.
  • Climate: The local climate in Chatsworth, GA, plays a major role in finding the appropriate size HVAC. Homes in warmer climates might need a system with a higher cooling capacity, while milder regions may need less.
  • Number of windows: Windows can be a major source of energy loss. The number, size, type of glass used, and whether they’re single or double paned can greatly impact heating and cooling requirements.
  • Amount of sun: A home that receives a considerable sunlight will inherently be warmer than one that doesn't, which impacts central air sizing. Home placement in relation to prevailing winds and number of nearby shade trees also affect the appropriate 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. Although the square footage of your home has a big impact on what size HVAC you need, other considerations also influence how much heating and cooling capacity is necessary to keep your home cozy.

Another typical mistake is not employing a professional. It's essential to have an experienced HVAC technician conduct a Manual J calculation, which takes all the essential aspects of your home into consideration to find the appropriate HVAC size.

Why Does HVAC System Size Matter?

An inadequately sized system can cause comfort problems and drive up your monthly power bills. Here's a deep dive into the pitfalls of a wrong-sized HVAC:

Issues with undersized HVAC systems:

  • Less longevity and breakdowns: HVAC systems that are too small often run constantly to attempt to regulate the temperature of a home, leading to excessive wear and tear. This can lead to breakdowns and even require premature HVAC replacement.
  • An unpleasant home: Small HVAC systems don't have enough power 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 operates nonstop trying to keep up uses more energy, increasing your monthly power bills and costing you money. A properly sized and energy-efficient HVAC system uses less power and helps to lower your monthly bills.

Issues from oversized HVAC systems

  • Wasted money: Larger HVAC systems tend to cost more money, so purchasing more heating and cooling capacity than your home requires is a waste of money.
  • Reduced lifespan and breakdowns: HVAC systems that are too big often cycle on and off, referred to as short cycling. This can cause wear and tear on your equipment, reducing its service life or requiring HVAC repair.
  • Humidity issues: 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 lead to indoor air quality issues, such as mold growth.
