Choosing a new air conditioning (AC) system for your Lubbock home requires balancing upfront costs with long-term energy savings. The most critical factor in this decision is the unit’s SEER rating. Understanding what this number means will directly impact your utility bills and overall comfort for years to come.
At Nugent Mechanical Contractors, we prioritize guiding our customers through efficiency ratings to ensure they make a smart, informed investment.
What is the SEER Rating?
SEER stands for Seasonal Energy Efficiency Ratio.
In the simplest terms, the SEER rating measures the efficiency of an air conditioner over an entire cooling season. It is calculated by dividing the total cooling output (in BTUs) during a typical cooling season by the total energy input (in Watt-hours) consumed during the same period.

Higher SEER = Greater Efficiency: A higher SEER number indicates that the unit uses less electricity to produce the same amount of cooling power.
The New Standard: Introducing SEER2
As of January 1, 2023, the Department of Energy (DOE) introduced a new testing standard for AC efficiency called SEER2.
| Rating | Standard | Efficiency Level |
| SEER | Old testing method | Phased out by DOE |
| SEER2 | New testing method | Current industry standard |
The new SEER2 testing method is designed to better reflect real-world operating conditions, particularly static pressure (airflow resistance), by using more realistic test procedures. Therefore, a unit rated at 14 SEER under the old system might be rated slightly lower, say 13.4 SEER2, under the new system, even though it’s the exact same piece of equipment.
The minimum efficiency standard for central AC units in Texas is now 14.3 SEER2.
How SEER2 Translates to Savings
In a climate like Lubbock’s, where summers are long and hot, choosing a higher SEER2 rating offers substantial benefits:
| SEER2 Rating Comparison | Potential Savings |
| 14 SEER2 | Current minimum standard. Good efficiency. |
| 16 SEER2 | Excellent efficiency. Often saves enough electricity to offset the higher unit cost within a few years. |
| 18 SEER2+ | High-Efficiency. Often includes variable-speed compressors, offering superior dehumidification and precise temperature control. Best choice for large homes or those prioritizing maximum long-term savings. |

The Investment: While a higher SEER2 unit has a greater upfront cost, the reduction in your monthly utility bills provides a return on investment (ROI) that can pay for the difference over the unit’s lifespan.
Why SEER2 Matters in Lubbock
-
Lower Utility Bills: The longer your AC runs, the more the efficiency gap between a 14 SEER2 unit and a 16 or 18 SEER2 unit widens. Given the sustained summer heat in West Texas, investing in high efficiency translates to immediate and substantial monthly savings.
-
Increased Comfort: Higher SEER2 systems often use two-stage or variable-speed compressors, which run for longer periods at lower capacities. This operation not only saves energy but also improves comfort by removing more humidity from the air, making your home feel cooler even when the thermostat setting is slightly higher.
-
Future-Proofing: As energy costs continue to rise, a higher SEER2 unit ensures your home is protected against future utility inflation.
When it’s time to replace your unit, don’t just ask about the price—ask about the SEER2 rating. Contact Nugent Mechanical Contractors to explore high-efficiency AC options perfectly sized for your home.
