What to Know When Replacing Your HVAC System

February 16, 2023

When it’s time to replace your HVAC system, you want to make an informed purchase. After all, buying a new heating and cooling system is a significant investment that you’ll live with for many years. Here are some things you need to know when you make this purchase.

HVAC System Efficiency Ratings

It’s probably been many years since you’ve purchased a new furnace or air conditioning system — and a lot has changed. HVAC technology has rapidly advanced, and today’s systems are more efficient than ever. When shopping for a replacement system, you want to consider the Seasonal Energy Efficiency Ratio (SEER) for air conditioning systems and the Annual Fuel Utilization Efficiency (AFUE) percentage for heating systems. The higher the SEER rating, the more efficient the system. The minimum SEER rating allowed by law for residential systems as of 2023 is 14. AFUE refers to how much fuel converts to energy. You want the AFUE percentage to fall between 80-90 percent, although some systems can have a 99% AFUE rating.

Keep in mind that you don’t have to get a top-of-the-line HVAC system to get an efficient system. Consider your budget and speak with a qualified installer to determine the best system for your situation.

Load Calculations

Another important factor is the system’s load requirements. The biggest mistake a homeowner can make when replacing their heating and cooling system is failing to have proper load calculations done and only upgrading their current model with the same size.

Load refers to how many British Thermal Units (BTUs) are required to heat and cool the home. Qualified HVAC installers have a precise formula they use to ensure correct calculations that guide you toward purchasing the most efficient system for your home.
