Although only eight percent of the world population has an air conditioner, 90 percent of American households use one.
Access to centralized air is important to American families. With summers constantly reaching record highs, we expect to see an even greater rise in air conditioning.
If you’re looking to upgrade or install a new heating and air system in your large home, you probably have a million questions.
What’s the best HVAC system for my home? What system size do I need?
Keep reading to learn how to choose the best heating and air solution for a big home.
Heating and Air Options
Heating, Ventilation, and Air Conditioning (HVAC) is the generalized term for using technology to control home temperature.
HVAC systems play a big role in overall home comfort. Given that we rely on these systems often, you want to be sure you make the best investment possible.
If you’re looking to replace both systems, you may want to consider installing a heat pump. In homes with moderate heating and cooling needs, these are the most energy efficient option.
However, a heat pump won’t work in all homes, so here are additional ways to choose the best heating and air options.
First, Check your Current System
You’ll need to be sure your current HVAC system ductwork is efficient and functional. Although you may be eager to have a new system installed immediately, you shouldn’t skip this procedure.
If you have leaks or blockages in your duct system, your new HVAC will be inefficient. Be sure to find a professional who can evaluate your current system.
The size of your new air conditioner will largely depend on the size of your home. Central air conditioners are measured by tons, which is defined as the ability to cool 12,000 BTU in an hour.
To get an idea of what size you may need, perform the following equation: multiply the square footage of your home by 30, and then divide by 12,000 and subtract 1.
[(Square footage X 30)/12,000]-1
For example, a 2,000 square foot home X 30 =60,000
Divide 60,000 by 12,000=5
Finally, subtract 1 for a tonnage of 4.
Climate, the shading of your home, and other factors will also affect the required size of your system.
This online calculator helps you to choose what furnace size can efficiently heat your home. The calculation takes into account the square footage of your home and your climate zone to come up with the number of BTUs your furnace will need to heat.
Furnaces can have variable settings:
- Single stage furnaces function on “high” at all times are less efficient
- Two-stage furnaces have a “high” and “low” option depending on your needs
- Variable speed furnaces are most efficient, running at the speed required to reach a certain indoor temperature
Upgrading your heating and air systems is an important investment to not only keep your home comfortable but also improve energy efficiency.
The above guidelines will help you choose the right system size, but you should seek professional help from local contractors to understand specific needs in your climate zone.
