Cost by home & system size

Square footage is the starting point — we confirm the exact size with a Manual J load calculation, since insulation, windows, and the two-story heat gain common in Mason builds all move the number.

Honest planning ranges, not a quote — every home is different. An oversized unit short-cycles and leaves Mason summers humid; an undersized one never keeps the upstairs cool. Right-sizing is where the real value is, and it's why your exact number comes from a free in-home visit.

Where Your Money Actually Goes

Should You Repair or Replace Your AC?

It's the question every Mason homeowner faces when an air conditioner starts acting up: is it worth fixing, or is it time for a new system? The honest answer comes down to three things — the part that failed, the age of the unit, and the refrigerant it uses. A minor repair like a capacitor or contactor on a newer, well-maintained system is almost always worth making. But a major repair such as a failed compressor, or a refrigerant leak in an older R-22 system, often points toward replacement, where the same money buys years of reliable, more efficient cooling instead of a short-term patch.

The 50% rule of thumb: when a repair would cost more than about half the price of a new system — or your AC is 12–20 years old and runs on phased-out R-22 — replacement is usually the smarter long-term move. Still weighing it? Read our repair-or-replace guide or the signs your AC is failing.

A Higher SEER2 Pays You Back Every Summer

SEER2 is simply the efficiency score of an air conditioner — a higher number means less electricity for the same cooling. Many builder-grade units we replace in Mason were rated SEER 8–10, so a modern system can cut summer Duke Energy bills by roughly 30–50%. Here's how the tiers compare:

A higher SEER2 costs more upfront but keeps paying you back across the system's 15–20 year life — we'll show you the payback math for your specific home and Duke Energy bill.

Three Ways the Real Cost Comes Down

The sticker price isn't what you actually pay. Between flexible financing, federal tax credits, and Duke Energy rebates, your out-of-pocket on a new Mason AC is often well below the quote — and we handle the paperwork.
