The key to smarter, more efficient HVAC investments
As a Raleigh-based HVAC contractor, we often get questions from business owners trying to make smart investments in their heating and cooling systems. One key metric should always be on your radar when selecting an HVAC system: the SEER rating. A system’s SEER rating directly impacts energy usage, utility costs, and long-term return on investment.
In this blog, we’ll break down what SEER ratings are, how they affect your business, and what to consider when choosing or upgrading an HVAC system in North Carolina.
What Is a SEER Rating?
SEER stands for Seasonal Energy Efficiency Ratio. It’s a measure of how efficiently an air conditioner or heat pump operates over a typical cooling season. Technically, it’s calculated by dividing the total cooling output during a normal cooling season by the total electric energy input over that same period.
In simpler terms: the higher the SEER rating, the more efficient the system.
Recently, the U.S. Department of Energy introduced a new metric: SEER2. This new standard reflects more real-world conditions, including the impact of external static pressure on HVAC systems. SEER2 ratings are slightly lower numerically than SEER but more accurate in predicting energy use.
Why SEER2 Ratings Matter
Raleigh and the surrounding Triangle area experience hot, humid summers. In this climate, businesses rely heavily on their air conditioning systems from late spring through early fall. As a result, HVAC energy usage can account for a significant portion of a commercial building’s utility expenses. Here’s why SEER matters specifically for local businesses:
- Energy Savings: Higher SEER units consume less power, helping reduce energy bills over time—critical for businesses that operate large spaces or require 24/7 climate control.
- Environmental Regulations: North Carolina, like many states, follows evolving federal guidelines on energy efficiency. Commercial HVAC systems are now required to meet minimum SEER2 efficiency standards.
- Customer Comfort: Efficient systems tend to provide more consistent temperature control and humidity regulation, which improves comfort for customers and employees.
- Building Compliance: Commercial building codes are also starting to demand higher efficiency equipment. Keeping up with SEER2 standards helps you stay compliant.
The ROI of High-SEER Systems
Let’s talk business. Investing in a high-efficiency HVAC system with a better SEER2 rating often delivers measurable ROI in the form of:
- Lower monthly utility bills
- Reduced maintenance and repair costs
- Tax deductions (via Section 179 for commercial HVAC)
- Increased property value and tenant appeal
But upgrading or selecting a commercial HVAC system isn’t just about picking the highest SEER2. You need a local partner who understands the nuances of energy codes, rebate programs, and the unique climate demands of the Triangle area.
