SEER2 Explained in Simple Terms

1. What Is SEER2?

SEER2 is a way of describing how efficiently a cooling system uses electricity during a typical season. You can think of it as a "miles per gallon" style number for air conditioning:

• Higher SEER2 = uses less electricity for the same cooling.
• Lower SEER2 = uses more electricity for the same cooling.

It does not tell you everything about comfort, noise, or quality, but it does give a rough idea of energy use on the cooling side.

2. What Is "Normal" SEER2?

Most new systems today meet updated efficiency rules, so you'll often see SEER2 numbers in a range something like:

• Basic systems: lower end of the current allowed range.
• Mid-range systems: comfortably above the minimum.
• High-efficiency systems: noticeably higher numbers.

The exact "cutoffs" depend on your region and local regulations, so instead of chasing one magic number, it's better to think in simple terms: higher SEER2 generally means better cooling efficiency, but also higher upfront cost.

3. Does SEER2 Affect My Comfort?

Indirectly, yes — but it's not the whole story. Comfort is more heavily influenced by:

• Whether the system is single-stage, two-stage, or inverter (how it ramps up and down).
• The quality of your ductwork and airflow.
• How well the system is sized and installed.

A modest SEER2 system with good ducts and careful installation can feel better than a high-SEER2 system installed poorly.

4. What Should I Do With SEER2 on My Quote?

Here are some simple ways to use the SEER2 info you see:

• Make sure the quote clearly lists the SEER2 rating or model number.
• Ask the contractor what other options exist slightly above or below that number.
• Ask how much of a difference the efficiency will make for your home and usage.

There's no universal "right" SEER2 — it's a tradeoff between upfront cost and electricity use over time.

5. Good Questions to Ask Your Contractor

• "What SEER2 range do you usually install in homes like mine?"
• "Are there one or two alternative models with a slightly different SEER2 I should consider?"
• "Can you explain how this system's efficiency will affect my cooling bills in simple terms?"
