Selecting the correct HVAC system size for your home is crucial. It impacts your home enjoyment and your power expenses. In this HVAC sizing guide, the experts at Farnell Heating & Air Conditioning Inc will explain how to choose the correct 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 comfort.

Why HVAC System Size Matters for Home Comfort and Efficiency

Proper HVAC size varies for every 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 hot or cold weather. However, an HVAC system that's too big is inefficient, wastes money and can cause problems that make your home less agreeable.

Key Features Pros Consider for HVAC Sizing in Mobile, AL

To determine the correct HVAC system size for a home, the HVAC installation experts at Farnell Heating & Air Conditioning Inc 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 elements, such as:

  • Home size: The total area of the home is arguably the most crucial 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 retains the indoor temperature better, which can affect how much heating and cooling power you need.
  • Regional Climate: The local climate in Mobile, AL, has a significant role in identifying the right size HVAC. Homes in warmer climates might need a system with a greater cooling capacity, while chillier regions may need less.
  • Window size: Windows can be a considerable source of energy loss. The number, size, type of glass used, and whether they’re single paned or double paned can greatly impact heating and cooling requirements.
  • Amount of sun: A home that gets a lot of sunlight will inherently 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 affect the appropriate HVAC size.

HVAC Size Mistakes Homeowners Often Make

A common mistake homeowners make when sizing their own HVAC system is to base their decision on square footage. While the square footage of your home has a significant impact on what size HVAC you need, other elements also influence how much heating and cooling capacity is necessary to keep your home cozy.

Another typical mistake is not engaging a professional. It's crucial to have a qualified HVAC technician perform a Manual J calculation, which takes all the essential aspects of your home into consideration to establish the appropriate HVAC size.

What Difference Does HVAC System Size Make?

An inadequately sized system can result in comfort problems and drive up your monthly power bills. Here's a detailed view of the pitfalls of a wrong-sized HVAC:

Issues with undersized HVAC systems:

  • Shorter system life 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 cause breakdowns and even require premature HVAC replacement.
  • An unpleasant home: Small HVAC systems don't have enough power to heat and cool your entire living space, which can result in hot, stuffy rooms or areas of your home that are uncomfortably cold.
  • Higher energy bills: An underpowered HVAC system that works constantly 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.

Issues from oversized HVAC systems

  • Unnecessary expenses: Larger HVAC systems tend to cost more money, so investing in more heating and cooling capacity than your home requires is an avoidable expense.
  • Less service 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 machine, 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 result in indoor air quality issues, such as mold growth.
