Finding the appropriate HVAC system size for your home is essential. It has a big impact on your ability to enjoy your home and your power expenses. In this HVAC sizing guide, the specialists at Giordanos Heating and Air Conditioning will explain how to choose the right size of heating and cooling system for your home, what features they take into account and why selecting the ideal size HVAC is so important to your satisfaction.

What Impact Does HVAC System Size Make on Home Comfort and Efficiency

Proper HVAC size differs 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 warm or frigid 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.

Critical Factors Professionals Consider for HVAC Sizing in Derby, CT

To select the appropriate HVAC system size for a home, the HVAC installation experts at Giordanos Heating and Air Conditioning carry out a Manual J load calculation to determine how many British Thermal Units (BTUs) are needed to heat and cool and the home. A Manual J calculation evaluates several factors, such as:

  • Home size: 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?
  • Amount of insulation: A well- insulated home retains the indoor temperature more efficiently, which can influence how much heating and cooling power you demand.
  • Regional Climate: The local climate in Derby, CT, has a major role in finding the appropriate size HVAC. Homes in hotter climates may require a system with an increased cooling capacity, while cooler regions may demand less.
  • Window placement and size: Windows can be a considerable source of energy loss. The number, dimensions, type of glass used, and whether they’re single or double pane can greatly impact heating and cooling requirements.
  • Sun and shade: A home that receives 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 affect the proper HVAC size.

HVAC Size Mistakes Homeowners Often Make

A frequent mistake homeowners make when choosing the size of home HVAC system is to rely solely on square footage. Although the square footage of your home has a significant 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 a skilled HVAC technician perform a Manual J calculation, which takes all the essential factors into consideration to find the appropriate HVAC size.

Why Does HVAC System Size Matter?

An improperly sized system can cause comfort problems and cost you money. Here's a detailed view of the pitfalls of a wrong-sized HVAC:

Undersized HVAC system problems:

  • Less longevity and breakdowns: HVAC systems that are too small often seem to run all the time to strive to maintain the temperature in a home, leading to more wear and tear. This can lead to breakdowns and even require premature HVAC replacement.
  • An uncomfortable home: Small HVAC systems are too weak to heat and cool your entire residence, which can lead to 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, 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.

Oversized HVAC system problems

  • Unnecessary expenses: Larger HVAC systems typically have a higher purchase price, so purchasing more heating and cooling capacity than your home needs is an unnecessary expense.
  • Shorter system life and breakdowns: HVAC systems that are excessively large often cycle on and off, referred to as short cycling. This can result in wear and tear on your machine, shortening 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 cause indoor air quality issues, such as mold growth.
