Selecting the right HVAC system size for your home is vital. It impacts your home enjoyment and your utility costs. In this HVAC sizing guide, the specialists at Evenaire Heating & Air Conditioning will explain how to determine the correct size of heating and cooling system for your home, what features they take into account and why choosing 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 varies for each home. Your HVAC system needs adequate heating and cooling capacity to make your entire home comfortable. It shouldn't have to work extremely hard to keep up in extremely scorching or chilly weather. However, an HVAC system that's too big is inefficient, increases your energy expenses and can lead to complications that make your home less agreeable.

Key Features Professionals Consider for HVAC Sizing in Pflugerville, TX

To determine the appropriate HVAC system size for a home, the HVAC installation specialists at Evenaire Heating & Air Conditioning 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 multiple factors, 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 be required to heat and cool?
  • Home insulation: A properly insulated home retains the indoor temperature better, which can affect how much heating and cooling power you need.
  • Climate: The local climate in Pflugerville, TX, has a significant role in determining the appropriate size HVAC. Homes in warmer climates may require a system with a greater cooling capacity, while cooler regions may need less.
  • Number of windows: Windows can be a major source of energy loss. The number, dimensions, type of glass used, and whether they’re single or double paned can considerably impact heating and cooling requirements.
  • Sun and shade: A home that receives a considerable sunlight will automatically 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 impact the proper HVAC size.

Common HVAC Size Mistakes to Avoid

A common mistake homeowners make when determining the size of their HVAC system is to focus only 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 necessary to keep your home comfortable.

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

What Difference Does HVAC System Size Make?

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

Issues with undersized HVAC systems:

  • Reduced lifespan and breakdowns: HVAC systems that are too small 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 unpleasant home: Small HVAC systems are too weak to heat and cool your whole home, which can lead to hot, stuffy rooms or areas of your home that are chilly and uncomfortable.
  • Increased energy bills: An underpowered HVAC system that works constantly 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 reduce 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 needs is an unnecessary expense.
  • Shorter system life and breakdowns: HVAC systems that are oversized often start and stop frequently, referred to as short cycling. This can lead to wear and tear on your equipment, shortening its service life or requiring HVAC repair.
  • Excessive indoor humidity: An HVAC system should regulate indoor humidity, but an oversized HVAC system might not run long enough to accomplish that task. This can cause indoor air quality issues, such as mold growth.
