Choosing the Right Size of HVAC System

HVAC Installation

Investing in a new HVAC system is a big decision that shouldn't be taken lightly. One of the most essential factors that you need to consider when selecting an HVAC system is the size. Your system's size will impact its efficiency, cost, and lifespan. If you choose a system that's too small, it won't be able to keep up with demand, leading to higher utility costs and a shorter lifespan. Conversely, a too-large system can lead to higher upfront costs and unnecessary energy waste.

1. Calculate Your Home's Cooling and Heating Needs

The first step in selecting the proper size HVAC system is determining your home's heating and cooling needs. This is usually done by calculating the square footage of your home and factoring in insulation, windows, and climate. However, relying solely on square footage can lead you wrong. Consulting with an HVAC professional is highly recommended to ensure accurate calculations. They'll also consider factors such as number of occupants and floor plan.

2. Consider Your Climate

Where you live is another crucial consideration when choosing an HVAC system. If you live in a hot, humid climate, you'll likely need a more powerful cooling system to handle high temperatures and high humidity levels. Conversely, a powerful heating system is paramount if you live in a colder climate. Weather patterns, as well as regional and local climate conditions, should be taken into account in addition to the home's insulation.

3. Choose a System with a SEER Rating of 14 or Higher

The SEER rating measures the efficiency of your system during cooling mode and stands for Seasonal Energy Efficiency Ratio. The higher this number, the more efficient your system is, leading to lower energy costs. As of January 2021, the minimum SEER rating for most new HVAC systems is 14.

4. Choose a System with a HSPF Rating of 8 or Higher

An HSPF rating measures the efficiency of your system during heating mode. This rating is equally essential to the SEER rating. The minimum HSPF rating set by the US Department of Energy is 8. Technological advances are making combining high SEER and HSPF ratings in the newest HVAC systems easier.
